Definitions
- the invention relates to a method for locking and unlocking coupling pieces for releasably connecting stacked containers on board ships according to the preamble of claim 1. Furthermore, the invention relates to coupling pieces for connecting stacked containers on board ships according to the preamble of claim 7 or claim 16.
- connection of stacked containers on board ships is done with coupling pieces between adjacent corner fittings at the corners of the containers.
- coupling pieces are used, which are designed as so-called semi-automatic twistlocks.
- These known coupling pieces are pre-locked on land under the lower corner fittings of a first (upper) container and then the first (upper) container with the coupling pieces pre-locked underneath are placed on a second (lower) container on board the ship, these coupling pieces having an automatic locking system bring the second (lower) container.
- the semi-automatic twistlocks must be unlocked manually to release them from the second (lower) container.
- fully automatic twist locks are also known. These have a mechanism that triggers an automatic vertical locking of the coupling pieces with the second (lower) container. To unload the ship, the mechanism unlocks the coupling pieces with the second (lower) container, so that the first (upper) container with the pre-locked coupling pieces can be lifted off the second (lower) container without manually opening the coupling pieces Need to become.
- the mechanisms in the coupling pieces for automatic locking of the same are very complex, which makes the coupling pieces considerably more expensive. Above all, the well-known fully automatic twistlocks have proven to be prone to failure in practice. Especially with older fully automatic twistlocks is special reliable automatic locking or unlocking is no longer guaranteed due to corrosion and wear.
- the invention is based on the object of providing a method for locking and unlocking coupling pieces for connecting containers on board ships and simply constructed coupling pieces, with which the containers on board the ship can be reliably locked and unlocked automatically.
- a method for solving this problem has the measures of claim 1. Accordingly, it is provided that by a movement of the ship caused in particular by the sea, the coupling pieces pre-locked under the first container are automatically locked with the second container and the locking of the coupling pieces with the second container is released when the ship no longer performs any significant movements, in particular lies quietly in the harbor.
- This method is based on the idea that a vertical connection of the containers stacked on top of one another by means of coupling pieces, in particular locking the coupling pieces to the second, preferably lower, container is only necessary when the ship is moving in rough seas. Accordingly, such sea-related ship movements are used to automatically bring about the locking of the coupling pieces to the second container that is then required. This lock is also automatically released when the ship is no longer carrying out any significant movements, for example in the harbor. The ship can then be unloaded without first having to manually unlock it from the second container, as in previous semi-automatic twistlocks.
- the coupling pieces pre-locked under the first container are automatically locked by heeling the ship with the second container. This locking occurs on every side when the ship is heeled. The lock is also released automatically only if the ship does not heel, or does not heel significantly. The containers can then be unloaded.
- the locking to the second, preferably lower container is carried out by an oscillating locking means in the respective coupling piece.
- the oscillating locking means is like this formed that at least one locking projection, in particular a locking nose, each locking means engages behind an elongated hole in the respective corner fitting of the second container only when the ship is heeling.
- a usual positive connection between the containers is created by the at least one locking projection or locking lug of the locking means, as is also the case with conventional coupling pieces, in particular semi-automatic twistlocks.
- the oscillating locking means is pivoted laterally in the coupling piece, as a result of which the locking projection or its locking nose reaches a position that engages behind the slot of the corner fitting of the second container. If, on the other hand, the ship is not heeling, the oscillating locking means reaches a vertical central position in which the at least one locking lug of the oscillating locking means does not engage behind the slot in the corner fitting of the second container and the vertical connection of the stacked containers is thus automatically canceled.
- the containers stacked one above the other are preferably locked by the locking projection of the locking means, which partially protrudes from the coupling projection of the coupling piece engaging in the corner fitting of the second (lower) container on the heeling ship, in particular with a locking lug, and thereby positively engages behind the corner fitting from the inside and vertical locking of the stacked containers.
- the locking means is at least supported on the coupling piece in the position pivoted when the ship is heeling and thereby locking the containers lying one above the other.
- the locking means is supported, it is preferably also clamped to the coupling piece.
- the locking means cannot pivot back under load when it engages behind the elongated hole from the inside of the corner fitting into a position in which the locking is released.
- the locking means is not acted upon, or at least not to the full extent, by the force which is exerted on the locking projection of the locking means, particularly in the vertical direction of the containers.
- This force namely a lashing force, is directly from the Locking projection introduced into the coupling piece without the remaining part of the locking means being acted upon by the lashing force.
- the oscillating suspension of the locking means need not be dimensioned so that it is able to absorb the lashing forces.
- a coupling piece for solving the above-mentioned object has the features of claim 7. Due to the oscillatingly mounted locking means in the housing of the coupling piece and the at least one locking lug of the locking means assigned to a coupling projection of the housing, a lock also of the coupling projection, to which the locking lug is assigned, can be brought about automatically during ship movements, in particular heeling of the ship, with the second container to be connected , The locking lug of the locking means only ever comes out of the coupling projection of the housing of the coupling piece when the oscillating locking means swings to one side, in particular by a heel of the ship.
- the locking means hangs vertically in the coupling piece, so that the longitudinal central axis of the locking means and the longitudinal central axis of the housing of the coupling piece coincide.
- the at least one locking lug of the oscillating locking means is then in the coupling projection, ie does not protrude from it. This automatically unlocks the stacked containers.
- the locking means is preferably designed as a locking pendulum, which can generally be moved back and forth in an upright transept plane. As a result, the locking pendulum can swing out when the ship is heeling and bring about a positive locking of the stacked containers. If, on the other hand, the ship has no heeling or no heel worth mentioning, the locking pendulum moves to a central starting position in which the containers are unlocked.
- the locking pendulum has a locking projection on an in particular lower end region.
- the locking projection is located in a recess in the coupling projection, which is in the second, preferably lower container, in particular its corner fitting. intervenes.
- the recess in the coupling projection is open on opposite sides, namely those that run parallel to the longitudinal direction of the ship.
- the locking nose of the locking projection of the locking pendulum which then protrudes laterally from the coupling projection in each case, can bring about a positive connection of the coupling piece with the second, preferably lower, container by the locking nose engaging behind the slot in the relevant corner fitting of the second container from the inside.
- the locking projection of the locking pendulum preferably has two opposite anchoring lugs which lie in the transept plane. Depending on which side the locking pendulum swings out due to a corresponding heeling of the ship, one of the locking lugs alternatively comes out of the coupling projection in order to be able to reach behind the slot in the corner fitting from the inside.
- both anchoring lugs are located at least as far in the recess of the coupling projection in question that this is through the slot in the corner fitting of the second ( lower) container hindurc fits.
- the locking pendulum is freely pivotable with an upper end region about an axis of rotation in the housing of the coupling piece, in such a way that the entire locking pendulum can pivot freely in opposite directions, preferably in a transept plane.
- the locking pendulum is freely movable in opposite directions when the ship is heeling, so that it can automatically move into a locking position.
- the locking pendulum is preferably mounted in the housing in such a way that it can be moved up and down.
- the axis of rotation at the upper end region of the locking pendulum can be brought into an upper end position by spring force when the locking pendulum is not loaded. In this upper end position, the locking pendulum is held in the unloaded state by the spring force.
- the locking pendulum can be locked non-pivotably in the state of locking the second (lower) container, ie under load, in the coupling projection which engages in the corner fitting of the second (lower) container.
- the locking pendulum can be clamped in the corresponding coupling projection in the loaded state. This prevents the anchoring pendulum from swiveling back unintentionally when it is under load, so that the vertical locking of the containers lying one above the other is reliably maintained when the ship is lifting and the locking pendulum is not loaded by the lashing forces.
- the locking pendulum is locked in its locking position by a central elevation arranged on the underside of the locking projection of the locking pendulum and a corresponding central elevation on the underside of the recess in the coupling projection in which the locking projection of the locking pendulum is arranged.
- the projections correspond in such a way that in the unloaded state of the locking pendulum as a result of the pendulum being raised by the spring-loaded axis of rotation, the projections can be moved past one another. This allows the locking pendulum to move freely in the unloaded state.
- a further coupling piece for solving the above-mentioned object which may be a preferred development of the coupling piece described above, has the features of claim 16.
- This relates to a special design of the coupling projection which engages in the corner fitting of the second (lower) container.
- this consists of a central part which engages the abutment and which extends through the slot of the corner fitting in question, and a locking head which continues the central part and lies within the corner fitting.
- this locking head is designed such that it projects at least on one side with respect to the central part, but only to such an extent that the entire coupling projection with the locking head can be passed through the elongated hole in the corner fitting in question.
- the coupling piece can be released from the second (lower) container without manual unlocking.
- the coupling projection is positively locked with the preferably lower container assigned to it. This locking takes place automatically when the ship carries out sea-related movements which cause the containers connected by the coupling piece to slip.
- the locking head preferably projects on all sides with respect to the central part. The result is that the containers can be locked in the vertical direction by displacing the containers lying one above the other in any direction by the coupling projection.
- FIG. 4 shows the coupling piece in a representation analogous to FIG. 3 in a central vertical section rotated by 90 °
- FIG. 5 is a plan view of the coupling piece in the state pre-locked under a lower corner fitting of an upper container
- FIG. 6 shows a section VI-VI through the coupling piece of FIG. 3,
- Fig. 8 shows the coupling piece in a representation analogous to FIG. 4 in the locked state.
- the coupling pieces according to the invention serve stacked containers 10 and 11 to connect with each other (Fig. ⁇ 1 and 2). Two containers 10 and 11 lying one above the other are connected by four identical coupling pieces.
- the coupling pieces are assigned to those at the corners of each container 10 and 11. It is about thereby around standardized corner fittings 12 which are identical to one another.
- a coupling piece in each case holds together corner fittings 12 of the upper container 10 and a lower container 11 lying one above the other.
- the containers 10, 11 are usually stowed in the longitudinal direction of the ship, so that the longitudinal axes of the containers 10 and 11 run in the longitudinal direction of the ship or parallel to it.
- the ship performs rolling and pounding movements, especially caused by swell.
- the ship executes heels to different sides.
- the containers 10 and 11 tend to slide sideways and also tip over.
- the coupling pieces serve to connect the containers 10 and 11 in such a way that they cannot slip relative to one another in the horizontal direction beyond an allowable dimension.
- the coupling pieces also prevent the corner fittings 12 of the containers 10 and 11 from lifting off, so that they cannot tip over.
- the locked coupling pieces also hold the containers 10 and 11 together in a substantially vertical direction.
- first container 10 or 11 Four identical coupling pieces are pre-locked on a first container 10 or 11, either under the four lower corner fittings 12 at the lower corners of the upper container 10 or on the four upper corner fittings 12 of the upper corners of the lower container 11.
- the container 10 or 11, on which the coupling pieces are pre-locked, is the first container.
- the coupling pieces are pre-locked under the lower corner fittings 12 of the upper container 10.
- the upper container 10 is the first container.
- the containers 10 and 11 are placed on top of each other.
- the upper container 10 is placed on the lower container 11 with the coupling pieces pre-locked under its lower corner fittings 11.
- This lower container 11 is therefore considered a second container in the following. Only after the lower container 10 has been placed on the lower container 11, with the coupling pieces according to the invention, the containers 10 and 11 are also locked in the vertical direction, automatically. This automatic locking takes place according to the invention using the heel of the ship. The heel is thus used to make the coupling pieces with the lower container 11 also vertical Lock direction. Likewise, the coupling pieces are automatically unlocked when the ship is no longer heeling.
- the corner fittings 12 assigned to the lower and upper corners of the containers 10 and 11 each have a standardized elongated hole 14 at least in their horizontal contact surfaces 13.
- the elongated holes 14 of all contact surfaces 13 of the corner fittings 12 run in the longitudinal direction of the containers 10 and 11, that is to say parallel to the longitudinal axis of the containers 10 and 11 and thus (in the case of containers 10 and 11 usually stowed in the longitudinal direction of the ship) also parallel to the longitudinal ship axis.
- This coupling piece has a one-piece housing 15 in the exemplary embodiment shown.
- the housing 15 forms a central abutment 16.
- the plate-like abutment 16 is located in the stacked containers 10 and 11 between a lower corner fitting 12 of the upper container 10 and an upper corner fitting of the lower Containers 11.
- Horizontal contact surfaces 13 of the corner fittings 12 lie on opposite sides of the abutment 16.
- the abutment 16 serves as a spacer between the contact surfaces 13 of adjacent corner fittings 12 of an upper container 10 and a lower container 11.
- Opposite sides of the abutment 16 are coupling projections 17 and 18 assigned.
- the coupling projections 17 and 18 are integrally formed on the abutment 16.
- An upward-facing upper coupling projection 17 is assigned to a lower corner fitting 12 of the upper container 10, while an opposing, downward-pointing coupling projection 18 is assigned to an upper corner fitting of the lower container 11.
- Each coupling projection 17 and 18 has a middle part 19, 20 adjoining the abutment 16, which extends through the elongated hole 14 in the respective corner fitting 12.
- the respective middle part 19 and 20 is continued by a locking head 21, 22.
- the locking head 21 and 22 of each coupling projection 17 and 18 is located inside the respective corner fitting 12.
- the upper coupling projection 17 is designed in a manner known per se, in such a way that by rotating the entire coupling piece about a vertical central axis 23, the coupling piece with the coupling projection 17 can be pre-locked and also unlocked under the lower corner fitting 12 of the upper container 10.
- the middle part 19 has diagonally opposite bevels 24, the surfaces of which run parallel to one another (FIG. 6). Because of the bevels 24, the central part 19, which essentially fills the elongated hole 14 of the lower corner fitting 12, allows the coupling piece to be rotated in the elongated hole 14.
- the locking head 21 of the coupling projection 17, which is located in the interior of the corner fitting 12, has a plate-like design and has an essentially rectangular base area, which approximately fills the elongated hole 14, so that the entire coupling projection 17 from below through the elongated hole 14 into the corner fitting 12 can be used.
- Two parallel longitudinal sides 25 of the locking head 21 run in the direction of the diagonally opposite bevels 24 of the middle part 19.
- the locking head 21 has diagonally opposite anchoring projections 26 which protrude on opposite sides of the middle part 19 (FIG. 5).
- the coupling piece is turned back, in the exemplary embodiment shown by approximately 30 °, the anchoring projections 26 of the locking head 21 come to coincide with the elongated hole 14.
- the upper coupling projection 17 is the Dome piece can be inserted through the elongated hole 14 into the corner fitting 12 and moved out of it.
- the lower coupling projection 18 is designed such that it fits through aligned the slot 14 in the upper corner fitting 12 of the lower container 11 when containers 10 and 11 are aligned.
- both the middle part 20 and the locking head 22 of the lower coupling projection 18 have an approximately right rectangular base area which is dimensioned such that it can be inserted through the elongated hole 14.
- the central part 20 has a greater lateral play compared to the elongated hole 14, in the longitudinal and also in the transverse direction of the elongated hole 14, than the locking head 22 located in the corner fitting 12. As a result, the locking head 22 protrudes slightly from the central part 20 on all sides ( 3 and 4).
- the locking head 22 can, however nevertheless - even though with less play compared to the central part 20 - push through the elongated hole 14 when the containers 10 and 11 are aligned with one another in such a way that their adjacent corner fittings 12 lie vertically, i.e. in alignment, one above the other (FIGS. 3 and 4).
- an elongated, vertical franking 27 is arranged in the housing 15 of the coupling piece.
- the franking 27 is located in relation to the central axis 23 of the coupling piece in the center of the housing (FIGS. 3, 4 and 6).
- the franking 27 extends from the upper coupling projection 17 through the abutment 16 into the lower coupling projection 18 (FIGS. 3 and 4).
- the clearance 27 is dimensioned in the area of the lower coupling projection 18 such that it extends continuously through the coupling projection 18 in the transept direction. This creates a continuous recess 28 in the lower locking head 22, which extends for the most part in opposite longitudinal sides 29 of the locking head 22 that run parallel to the direction of the nave and forms large-area openings therein (FIGS. 3 and 5).
- an underside of the franking 27 or the recess 28 is formed in the locking head 22.
- This underside 30 is raised in relation to the transept direction, namely forms a central projection 31 on the underside 30.
- the apex 32 of the projection 31 lies on the central axis 23 of the housing 15 of the coupling piece.
- the underside 30 of the locking head 22 thus falls from the central apex 32 to opposite directions towards the respective longitudinal side 29 (FIGS. 3 and 5).
- a locking pendulum 33 serving as a locking means is pivotably mounted in the recess 28 in the housing 15 of the coupling piece.
- the locking pendulum 33 is pivotally or pivotally mounted at the upper end region about a horizontal axis of rotation 34 located in the region of the locking head 21 of the upper coupling projection 17.
- the horizontal axis of rotation 34 extends in the longitudinal direction of the ship, so that the locking pendulum 33 can be freely pivoted back and forth about the axis of rotation 34 in the direction of the transept. If the ship is not heeling, ie essentially lying straight, the locking pendulum 33 is in a central position, the vertical longitudinal central axis of the locking pendulum 33 lying on the central axis 23 of the coupling piece (FIG. 3).
- the locking pendulum 33 When the ship is heeling, the locking pendulum 33 is pivoted in the direction of the heel side about the axis of rotation 34, so that the longitudinal central axis of the locking pendulum 33, starting from the axis of rotation 34, is at an angle to the central Axis 23 of the coupling piece extends, which corresponds approximately to the angle of the heel of the ship (Fig. 5).
- a horizontal bolt 35 lying on the axis of rotation 34 is mounted in the locking head 21 of the upper coupling projection 17.
- the bolt 35 extends through a vertical elongated hole 36 in the upper end region of the locking pendulum 33.
- the length of the elongated hole 36 corresponds approximately to twice the diameter of the bolt 35 (FIGS. 3 and 5).
- the pin 35 for forming the axis of rotation 34 is in a certain way floating, namely mounted in the vertical direction on the central axis 23 of the coupling piece and can be moved up and down in the upper coupling projection 18.
- Opposing ends of the bolt 35 are supported on a respective compression spring 37.
- the two compression springs 37 are inserted with vertically parallel longitudinal axes in recesses 38 accessible from the outside on opposite sides of the locking head 21 of the upper coupling projection 17.
- the indentations 38 lie opposite one another in the transept direction (FIGS. 4 and 6).
- Opposing end regions of the bolts 35 are supported in elongated holes 39 accessible from the outside in the locking head 21 of the upper coupling projection 17.
- the elongated holes 39 are formed like the elongated hole 36 in the upper end of the locking pendulum 33 and lie coaxially on opposite sides of this elongated hole 36.
- the bolt 35 is held immovably in the elongated holes 39 by means of releasable holding brackets 40 Form locking head 21 closed so that this elongated hole 39 is not continuous. In this case, only the opposite, continuous slot 39 needs to be closable by a bracket 40.
- the locking pendulum 33 has a locking projection 41 in the lower end region.
- the locking projection 41 is an integral part of the locking pendulum 33, that is to say molded onto it.
- the locking projection 41 has an approximately inverted bell-like cross section in the transept direction (FIGS. 3 and 5).
- a lower side of the locking projection 41 is provided with a downward-pointing curvature which has a central, arch-shaped projection 42 lying on the longitudinal central axis of the locking pendulum 33.
- the central apex 43 of the projection 42 is located on the central axis 23 of the coupling piece, so that the apex 43 of the coupling element Projection 42 is located below the locking pendulum 33 perpendicularly above the central apex 32 of the projection 31 of the underside 30 of the recess 28 in the lower coupling projection 18.
- the locking projection 41 has opposite locking lugs 44 and 45 as viewed in the transept direction. These are formed by a design of the locking projection 41 starting from the lower projection 42 of the locking projection 41 and widening upwards on both sides.
- the maximum width of the locking projection 41 with its opposite locking lugs 44 and 45 is dimensioned such that it is approximately the width of the locking head 22 of the lower coupling projection 18 corresponds to the transept direction (FIG. 3).
- both locking lugs 44 and 45 of the locking projection 41 of the locking pendulum 33 lie within the recess 28 of the lower locking head 22 when the locking pendulum 33 is in its undeflected rest position, i.e. the vertical central axis of the locking pendulum 33 approximately on the central axis 23 of the housing 15 of the Coupling piece (Fig. 3).
- the length of the locking pendulum 33 is dimensioned such that when the bolt 35 is pushed up by the compression springs 37 and then strikes against the upper ends of the elongated holes 39 in the upper coupling projection 17, the locking pendulum 33 in the opening 27 in the housing 15 of the coupling piece is free Transept direction is movable back and forth.
- the projection 42 does not lie on the lower end of the locking projection 41 of the locking pendulum 33 on the projection 31 of the underside 30 of the recess 28 in the lower coupling projection 18.
- the apices 32 and 43 of the projections 31 and 42 are then slightly spaced apart (FIG. 3).
- the locking pendulum 33 is deflected in one direction on the transverse plane, that is to say the locking pendulum 33 is pivoted to one side (FIG. 7), a locking lug on the locking projection 41 of the locking pendulum 33 (in FIG. 7 the left locking lug 44) moved to 'one side of the locking head 22 of the lower coupling projection 18th
- An upper contact surface 46 of the locking lug 44 then engages from the inside of the corner fitting 12 a lateral edge region of the elongated hole 14 in the corner fitting 12. This results in a vertical locking of the containers 10 and 11 by the coupling piece.
- the projection 31 comes to rest on the lower end of the locking pendulum 33, namely on the underside of the locking projection 41, on an obliquely outwardly extending section of the underside 30 of the recess 28 in the lower locking head 22, so that the corner fitting 12 of the container 11 opens the locking lug 44 of the locking projection 41 exerts force to support the locking projection 41 of the locking pendulum 33 on the underside 33 of the locking head 22 of the lower coupling projection 18 (FIG. 7).
- the upper coupling projections 17 of the coupling pieces are inserted through the elongated holes 14 in the lower corner fittings 12 of the upper container 10 and then the coupling pieces are rotated about their central axis 23 relative to the corner fittings 12, preferably by approximately 30 °. Thereafter, the anchoring projections 26 on the upper coupling projection 17 of each coupling piece engage opposite edge regions in the elongated hole 14 from the inside of the respective corner fitting 12 (FIG. 3).
- the upper container 10 is now placed vertically on the lower (second) container 11 already on board the ship with the (four) coupling pieces (FIG. 1) pre-locked under its lower corner fittings 12.
- the locking pendulums 33 in the coupling pieces are in their central starting position, in which the vertical central axes of the locking pendulums 33 lie approximately on the vertical central axes 23 of the coupling pieces (FIG. 3).
- the opposing locking lugs 44, 45 of the locking pendulums 33 are located within the lower coupling projections 18 of the coupling pieces, so that the lower coupling projections 18 through the elongated holes 14 in the upper corner fittings 12 of the lower container 11 can be passed through (Fig. 3).
- the abutments 16 of the coupling pieces are located between the contact surfaces 13 of adjacent corner fittings 12 of the superimposed containers 10 and 11 (FIG. 3).
- the locking pendulums 33 remain in the undeflected starting position, as a result of which the coupling pieces do not yet lock the containers 10 and 11 against lifting in the vertical direction (FIG. 3).
- the containers 10 and 11 are secured by the coupling pieces in the undeflected starting position of the locking pendulums 33 only against relative displacement in the horizontal direction.
- the containers 10 and 11 are automatically locked vertically by the locking pendulums 33 of the coupling pieces which move to one side as a result of the heeling. 2 and 7, a heeling of the ship to port is shown. Then the locking pendulums 33 swing in the coupling pieces to port. As a result, the left locking lugs 44 of the locking projections 41 of the locking pendulums 33 pass through the corresponding open longitudinal side 25 of the coupling projection 18, so that the locking lugs 44 project laterally relative to the locking heads 22 of the lower coupling projections 18 (FIG. 7).
- the compression springs 37 press the locking pendulums 33 upwards with the bolt 35, so that the locking pendulums 33 can swing freely and the locking lugs 44 can thereby come out of the recesses 28 in the coupling projections 18 laterally to the outside. If the upper container 10 now lifts up from the lower container 11 or at least the upper container 10 is laterally tilted relative to the lower container 11, all locking lugs 44 moved out of the coupling projections 18 or only the locking lugs 44 of two coupling pieces lying on one side come to rest under one lying next to the elongated holes 14 inner edge region of the corner fittings 12.
- the undersides 30 of the recesses 28 in the lower coupling projections 18 fall off to the sides from the central apices 32 of the projections 31 on the undersides 30 of the recesses 28, the oblique side surfaces of the undersides 30 of the recesses 28 in the lower coupling projections 18 prevents the locking pendulums 33 from moving back under load.
- the locking pendulums 33 are thus reliably secured under load in the position causing the containers 10 and 11 to lock, specifically clamped.
- the transmission of the lashing forces from the locking lugs 44 into the coupling projections 18 prevents the locking pendulums 33 - apart from the locking lugs 44 - from absorbing the lashing forces.
- the bolts 35 supporting the locking pendulums 33 do not need to absorb the loads that occur when the containers 10 and 11 are locked.
- the locking tabs 44 on the inside of the corner fittings 12 are released, whereby the compression springs 33 move the bolts 35 for mounting the locking pendulums 33 up again.
- the locking pendulums 33 are also pulled up, so that the apexes 43 of the projections 42 under the locking pendulums 33 are spaced apart from the undersides 30 of the recesses 28 in the lower coupling projections 18.
- the locking pendulums 33 can then move back into the starting position (FIG. 3), in which the containers 10, 11 are unlocked again in the vertical direction. Then the ship cranks to the other side, i.e.
- the upper container 10 is only to be aligned relative to the lower container 11 such that the elongated holes 14 of the adjacent corner fittings lie approximately on top of each other. Then the locking heads 22 of the lower coupling projections 18, which are wider than the central parts 20, can also be pulled out through the elongated holes 14 in the upper corner fittings 12 of the lower container 11.
