In FIG. 3, a number of vehicles s are arranged in an aligned state on the deck C, and the length of each vehicle s alone is, for example, about 12 m. As shown in Fig. 6, the front part is supported by a portable support base 5 and the rear part is supported by wheels 6 mounted on the chassis of each vehicle s. It is intended to be run and moved.

Each of the B deck, C deck, D deck, etc. is provided with a belt tension fixing device 7 at each of a number of specific positions p (indicated by 〇 in FIG. 3) related to the arrangement of the vehicle s. The following describes each belt tension fixing device 7 with reference to FIGS. 7 to 14.

That is, as shown in FIG. 7 and FIG. 8, the concave portion 8 is formed at each of the specific positions P on the deck f. The recessed part 8 is an up-and-down rectangular tube member ⁸ a, It is surrounded by a bottom plate 8b fixed to the lower end thereof. Reinforcing members 9a and 9b are installed vertically and horizontally on the inner peripheral surface near the upper end opening of the rectangular tube member 8a, and the upper surface of the reinforcing members 9a and 9b is liquid-tight on the upper surface side. The upper plate 10 is bolted so as to form a shape, and four circular holes 10a are formed in the upper plate 10 as shown in FIG. The guide cylinder member 11 is extended downward in each circular hole 10a force, and at this time, the upper end 11a of the guide cylinder member 11 is made thick and the upper end corner of the inner peripheral surface is formed. p 1 has an arc shape, and the lower part 11 b is relatively thin.

As shown in FIG. 10, four belt holding portions 12 are fixed to the upper surface of the bottom plate 8b. As shown in FIGS. 8 and 11, each belt holding portion 12 has a pair of upright plates 12a, 12a arranged in parallel to each other and a pair of upright plates 12a, 12a. A pair of upright plates 12a, 12b, and a pair of upright plates 12a, 12a. The take-up shaft 13 is mounted in a cross-linkable manner only between rotations while being freely rotatable, and the base end of the belt 14 is connected to the take-up shaft 13 so that the pair of upright plates 12 a and 12 a The belt 14 is stored in a wound state. To fix the belt holding portions 12 and the recessed portions 8, the bottom plate 12 b and the bottom plate 8 b are fastened with bolts 15, and the side plate 12 c and the square tube member 8 a are connected to a plurality of pin members. The upper end edges of the pair of upright plates 12a and 12a and the corresponding lower end of the guide tube member 11 are densely joined. Thus, each belt holding portion 12 is firmly fixed to the recess 8.

As shown in FIGS. 7, 8 and 11, each belt holding portion 12 has a belt winding force applying means 17 for applying a belt winding force to the winding shaft 13. And a driving force applied from the outside to the winding shaft 13 to send the winding shaft 13 to the belt winding side r 1 and rotate the same. And a booster feed rotating mechanism 1 ^8, and卷取Rijiku 1 3 half turns regulating means 1 9 and restricts the rotation of the reverse belts Certificates up side r 1 (also up side), the winding Winding shaft rotation enabling mechanisms 20 and 21 for changing the winding shaft 13 to a freely rotatable state are provided.

The belt winding force applying means 17 is provided with a coil spring 22 as a kind of spring member between the extension 13a at one end of the winding shaft 13 and one of the upright plates 12a. When a pulling force of a specified magnitude or more is applied to the tip of the belt 14 wound around the shaft 13, the winding shaft 13 is rotated against the elasticity of the coil spring 22 to rotate the belt 14. When the pulling force is removed, the winding shaft 13 is rotated to the belt winding side r 1 by the elastic force of the coil spring 22, and the belt 14 is turned into the winding shaft 13. It is said that the operation of winding it up can be obtained.

The boosting feed rotation mechanism 18 includes a pair of ratchet wheels 23, 23 fixed to both ends of the winding shaft 13 and positioned outside the respective upright plates 12a, 12a. An input lever 24 having an arm pivotally attached to both ends of the winding shaft 13 outside the pair of ratchets 23, 23, and an arm length between the arms of the input lever 24. It consists of a feed pawl 25 that is mounted so that it can be displaced in any direction. The input lever 24 is connected to the free ends of the pair of arms by a horizontal member 24a, and an input portion 2 for inputting an external driving force to a central portion of the length of the horizontal member 24a. 4b is formed. The feed pawl 25 is a substantially U-shaped plate member in plan view, and is formed with protrusions 25 a and 25 a at two places in the middle of the length of the main body, and left and right sides 25 b and 2 5b is passed through guide holes 24c, 24c formed in the corresponding input levers 24 along the length of the arms. The tips of a and 25a are passed through through holes a and a formed in the horizontal member 24a. The compression springs 26, 26 are externally fitted to the projections 25a, 25a, respectively. The other end is in contact with the horizontal member 24 a of the input lever 24.

The half-rotation control means 19 is provided with a detent 27 in an approximately gourd-shaped guide through-hole b formed at a specific location facing the pair of uprights 12a and 12a. At the same time, a compression spring 28 acting to bring the locking portion 27a of the detent pawl 27 close to the ratchet wheel 23 is provided, and the compression spring 28 is always engaged by the elasticity of the compression spring 28. The stop part 27 a is kept pressed against the outer periphery of the ratchet wheel 23, and the ratchet wheel 23 is allowed to rotate to the belt winding side r 1, but is returned to the return side. The rotation of 23 is regulated.

A double-acting pneumatic cylinder 29 is installed between the input part 24 b of the input caller 24 and the reinforcing member 9 a so that the output part 29 a is reciprocated linearly by air pressure. The input lever 24 is reciprocally swingably displaced around the winding shaft 13 by the reciprocal displacement of the output portion 29a.

Therefore, when the output portion 29 a is displaced downward and the input lever 24 is swung to the belt winding side r 1 around the winding shaft 13, the detent pawl 27 is a ratchet wheel 2 3 Since the rotation to the belt winding side r 1 is not restricted away from the pawl, the feed pawl 25 is connected to the pawl valley of the pawl 23 via the compression springs 26 and 26. In the locked state, the input lever 24 and the ratchet wheel 23 are rocked and displaced integrally with each other, and the reciprocating displacement causes the winding shaft 13 to be belt-wound integrally with the ratchet wheel 23. When the output part 29a is displaced upward and the input lever 24 is swung to the return side, the return stop pawl 27 is used for the ratchet wheel 23. In order to restrict the return rotation, the feed pawl 25 is pushed out by the elastic force of the compression springs 26 and 26 and the pawl 23 of the rotation-restricted pawl 23 The input lever 2 4 slides along the circumference, and the input lever 24 moves together with the feed pawl 25 It is displaced relative to 23 on the return side. When the vertical swing displacement of the input lever 24 is repeated, the winding shaft 13 is intermittently fed and rotated toward the belt winding side r1.

The winding shaft rotatable mechanism 20 is composed of a restriction releasing driving means for releasing the rotation restriction of the winding shaft 13 by the rotation half restricting means 1 ^. The rotatable mechanism 21 comprises a regulation releasing member for releasing the restriction of the rotation of the winding shaft 13 by the feed pawl 25 of the booster feed rotating mechanism 18.

The restriction release drive means 20 is a relatively small single-acting pneumatic cylinder 31 on a support piece 30 protruding laterally from the side plate 12 c between the pair of upright plates 12 a, 12 a. And the output part of the pneumatic cylinder 31 is fixed to the center of the return detent 27 in the direction of the center axis of the ratchet wheel, and compressed air is supplied to the pneumatic cylinder 31. When supplied, the output part is displaced downward by the force of the compression spring 28 mounted in the pneumatic cylinder 31, and the downward displacement causes the detent 27 to be locked. Principal part 27a is the ratchet wheel 23: It is separated from the outer peripheral edge, and the detent is stopped. When the compressed air supplied to (1) is discharged, the output of the pneumatic cylinder (31) is resilient by the spring (27). By being displaced upward, the detent pawl returns to the original position, and the rotation of the detent wheel 23 to the return side is regulated again.

The restriction release member 21 is made of a cam plate fixed to the outer surface of each of the upright plates 12a and 12a, and as shown in FIG. The radius of each point from the center of the winding shaft 13 is set to be larger than that of the crest of the claw wheel 23 and the belt winding side r 1 of the specific range portion c 1. In addition, a slope c2 is formed so that the radius length gradually decreases as it moves toward the belt winding side r1. Has been done. The specific range part c 1 and the inclined part c 2 of the restriction release member 21 are required to be locked by the left and right sides 25 b and 25 b of the pawl 25 by the elasticity of the compression spring 26 to 26. When the input lever 24 is pivotally displaced from the position of the imaginary line e to the belt winding side r1 when the input lever 24 is displaced from the position indicated by the imaginary line e, the feed portion is engaged. The pawl 2 5 is gradually displaced outward from the radius of the pawl wheel 2 3, and the specific range portion c 1 is set so that the feed pawl 25 is closed when the input lever 24 is positioned closest to the belt winding side _r 1. The vehicle is moved away from the radius of the peak of the claw of car 23 outward.

Therefore, even if compressed air flows into the pneumatic cylinder 31, the detent pawls 27 are separated from the ratchet wheel 23 against the elasticity of the compression springs 28, and the winding shaft 13 is fed. When the pawl 25 is pushed up against the elasticity of the compression spring 28 at a specific range portion c 1 of the restriction release member 21, the pawl 25 is freely rotatable. When a manual pulling force is applied to the belt 14 in the rotatable state, the winding shaft 13 is rotated by the pulling force, and the belt 14 wound and stored therein is pulled outward. Will be issued.

—A pair of rollers 32, 32 are mounted above the pair of uprights 12a, 12a. These rollers 32, 32 support the belt 14 and support the winding shaft. It acts to determine the position of the belt 14 taken in and out when it comes in and out. A lower plate 33 is fixed to the lower end of each guide cylinder member 11, and a belt passage hole 33 a is formed at a position directly above the pair of rollers 32, 32 at the lower plate 33. The belt passage hole 33a is provided with a brush body g for rubbing the belt 14 for cleaning. A circular lid 34 is placed at the upper end opening of each guide cylinder member 11 in a liquid-tight manner by a sealing member (not shown). At this time, the circular lid 34 is bell-shaped to prevent loss. To hook member 3 5 connected to the tip of It is better to connect them with a relatively short string of about 10 cm to several tens cm. A locking bar 36 bent in a U-shape is fixed to a central portion of the lower surface of the circular lid 34, and a knob bar piece 34a is fixed to a concave portion of the upper surface. At this time, the hook member 35 is hooked on the hook bar 36. As shown in FIG. 13, a pair of frame-shaped covering members 37, 37 are mounted on the upper surfaces of the capturing members 9a, 9b, and these frame-shaped covering members 37, 37 are mounted on the inner side thereof. The side bar portions 37a, 37a are surrounded by portal bending members 38, 38 fixed to the upper surface of the reinforcing members 9a, 9b, and are loaded on the frame-shaped cover members 37, 37. It is mounted so that a large load is not applied to the circular lid 34 etc. even when the body is placed, and each frame-shaped cover 37 swings around the side bar 37 a. Is to be done. Reference numeral 39 in FIG. 7 denotes a plate member fixed to the inner surface of the rectangular tube member 8a to prevent the belt holding portion 12 from floating.

The structure of the belt tension fixing device 7 has been described above. In the illustrated example, four belt holding portions 12 are provided in one recess 8. However, the present invention is not limited to this. And the members related thereto may be any number.

A control box (not shown) for controlling the pneumatic cylinder 29 and the pneumatic cylinder 31 is provided for each group of the belt tension fixing device 7. The control box is provided with a “fixed position”, which is a handle position where the pneumatic cylinder 29 is in a shortened operation state and the input lever 24 is in a state shown by a solid line in FIG. 7, and a pneumatic cylinder 29 A winding handle that can be switched to one of the "winding position", which is a handle position in which the input lever 24 is set to the state shown by the imaginary line e in FIG. 7 as the extension operation state. And the compressed air is supplied from the pneumatic cylinder 31 to the pneumatic cylinder 31 to supply compressed air to the other pneumatic cylinder 31 so that the winding shaft 13 can rotate freely. Let the air flow out and take up the shaft 13 A stop handle is provided that can be switched to either one of the "regulation position", which is the handle position for restricting the return rotation to the return side.

Next, the procedure for placing the vehicle s on the deck f of the roll-on-off ship described above and lashing it, and the operation of each part will be described.

With the hull 1 moored to the quay, the bow lamp 2 and the stern lamp 3 are opened and lowered, and are hung over the quay, and the towing vehicle s is used to pull the vehicle s loaded with containers. And move it from the quay to the inside of the ship, for example, first move it on the D deck, and then, if necessary, move it on the other deck f via the in-ramp ramps 4a to 4d. This process is repeated, and a number of vehicles s are aligned at specific positions on each deck f as shown in FIG.

During this alignment work, the circular lid 34 and the frame-shaped covers 37, 37 of each belt tension fixing device 7 are closed as shown in FIG. The fixing device 7 does not interfere with the vehicle s when the vehicle s travels, and the loading of the vehicle s is smoothly performed without being affected by the belt tension fixing device 7. At this time, the pair of frame-shaped cover members 37, 37 of each belt tension fixing device 7 is mainly supported on the upper surface of the reinforcing members 9a, 9b, so that the wheel 6 of the vehicle s is mounted on the frame-shaped cover member 3. The weight does not act directly on the circular lid 34 even if it is placed on 7, 37.

Wheels 6 of each aligned vehicle s are provided with a bollard, and the front of the chassis of the vehicle s is supported on a portable support 5 as shown in FIG. 4, whereby each vehicle s It is positioned at a specific position on deck f.

Next, a vehicle corresponding to the position of a group of belt tension fixing devices 7 controlled by a stopper handle and a winding handle in one of the control boxes. Lashing is performed for each s group.

First, the stopper handle is positioned at the “regulation release position”. As a result, the rotation of the winding shaft 13 toward the return side by the return stop pawl 27 of the rotation half-restricting means 19 is released. In this state, when the winding handle S is positioned at the “fixed position”, the feed pawl 25 is pushed up by the specific release point c 1 of the restriction release member 21 so as to be separated from the ratchet wheel 23. As a result, the rotation restriction to the return side by the feed pawl 25 of the pawl wheel 23 is released. As a result, there is no restriction on the rotation of the winding shaft 13 to the return side, and the winding shaft 13 can freely rotate to the return side.

Thereafter, each frame-shaped cover 37 is swung upward around the inner rod member 37a as shown in FIG. 14, and each circular lid 34 is moved upward from the upper end opening of the guide cylinder member 11. Remove to. Then, a manual pulling force is applied to the belt 14 of each belt holding portion 12, and at this time, the winding shaft 13 resists the elasticity of the coil panel 22 by the amount that the belt 14 is pulled out. The belt 14 wound around the belt holding portion 12 is pulled out through each guide tube member 11 by a length corresponding to the pulling operation. The hook members 35 of the four belts 14 thus pulled out are fixed to the side of the vehicle s on one side adjacent in the row direction of the vehicle s row as shown in FIGS. 4 to 6. Lock to the locking member h.

At this time, the relationship between the vehicle s-row and the belt tension fixing device 7 is preferably such that two adjacent vehicles s-row are opposed to each other in a direction orthogonal to the row direction, as shown in FIGS. The four belts 14 of one belt tension fixing device 7 having four belt holding portions 12 are pulled out from the locking members h of the four vehicles s as shown in FIG. Lock each of 5. However, at the side of the vehicle s row to be lashed that does not face the other vehicle s row, it is not possible to pull the two vehicle s rows as shown in Figs. 4 to 6 on the same belt tension fixing device 7. One belt tension A belt tension fixing device 7 having one or two belt holding portions 12 or a belt using a belt 14 of a part of the belt holding portions 12 of the fixing device 7 is formed. If the belt tension fixing device 7 does not exist at an appropriate position with respect to the vehicle s, the necessary lashing is manually performed using a rope or the like. After the belt hang-up process of the group of vehicles s is completed as described above, first, the stopper handle is switched from the “regulation release position” to the “regulation position”. As a result, the rotation half regulating means 19 regulates the rotation of the ratchet wheel 23 and the winding shaft 13 toward the return side. Next, the winding handle is moved in the order of “fixed position”, “coiling position”, and “fixed position”. At this time, first, when the winding handle is located at the “winding position”, the output portion 29 a of the pneumatic cylinder 29 is displaced downward, and the incoming caller 24 is swung to the belt winding side r 1. As a result, the feed pawl 25 rotates the pawl wheel 23 to the winding side rl on the belt take-up side 23, and the rotating position of the pawl wheel 23 rotated in this way returns. The rotation toward the return side is restricted by the pawl 27. Then, when the winding handle is located at the “fixed position”, the output part 29 a of the pneumatic cylinder 29 is displaced upward and returns to the original position, and the feeding jaw 25 is the jaw wheel 23. Although the rotation is not restricted, the rotation of the ratchet wheel 23 toward the return side is regulated by the return stop pawl 27, and the input lever 24 is shown by a solid line in FIG. Returns to the state. When the winding handle is moved two or three times in the order of “fixed position”, “winding position”, and “fixed position”, the above-described series of operations is repeated. The ratchet wheel 23 and the take-up shaft 13 are intermittently fed and rotated to the belt take-up side r 1, thereby removing the slack in the belt 14 and moving it to the pneumatic cylinder 29. Tensioned at a specific tension related to the pressure of the supplied compressed air, each vehicle s is reliably lashed and fixed on deck f. Note that the winding handle at the end of lashing is Position ”.

By performing the same processing for the other vehicle S rows, all vehicles s on each deck f are in a lashed state. Thereby, each vehicle s is basically in a state where the four corners are pulled downward by the belts 14 as shown in FIG. 15B.

After the lashing is completed, the tension of the belt 14 is stably maintained at a required level for a long period of time due to its elasticity and the like. However, the tension of the belt 14 may be insufficient during the voyage, etc., but in such a case, the belt 14 is to be re-tightened. As described above, the belt 14 is moved in the order of “fixed position”, “winding position”, and “fixed position”, whereby each belt 14 is driven by the pressure of the compressed air supplied to the pneumatic cylinder 29. Tightened by the specific tension related to

The lashing in the above example is normally performed, but when the sea is windy and the cruising distance is short, each vehicle s is placed on the bell on the rear side of the chassis as shown in Figure 15A. G is omitted, and only the left and right corners on the front side of the chassis are pulled downward by the belt 14.

When unloading vehicles s that have been lashed on deck f, the lashing of those vehicles must be removed.First, the stopper handle is switched from the "restricted position" to the "restricted position". Next, the winding handle is moved in the order of “fixed position”, “winding position”, and “fixed position”. As a result, the output portion 29a of the pneumatic cylinder 29 instantaneously applies a rotational force to the belt winding side r1 to the winding shaft 13 to temporarily tighten the belt 14. After that, this tension is lost, and the belt 14 rotates the winding shaft 13 slightly to the return side due to its own elasticity, and loosens only by the winding force of the coil spring 22. State. Next, the hook member 3 5 hooked on the locking member h of each vehicle s is connected to the locking member h. , Whereby each vehicle s is released from lashing by the belt 14 and becomes free. The belt 14 removed from the locking member h is wound by the rotation of the belt winding side r 1 given by the elasticity of the coil spring 22 while being related to the operation of the belt 14 manually. It is wound around the shaft 13 and stored in the belt holding portion 12. Finally, the hook member 35 is locked to the hook bar 36 of the circular lid 34, and the circular lid 34 in this state is placed on the upper end opening of the guide cylinder member 11 so as to cover it. I do. The circular lid 34 placed in this way is pulled downward by the elastic force of the coil panel 22 through the belt 14 and the hook member 35, so that the placed state is stably maintained. Is done. Then, as shown in Fig. 13, all the circular lids 34 of each belt tension fixing device 7 are placed on the corresponding guide tube member 11, and the frame-shaped covers 37, 37 are placed in a horizontal posture. And Thereafter, each vehicle s whose lashing has been released is unloaded and moved, and at this time, each belt tension fixing device 7 can be stepped on the vehicle s as described above, and the vehicle s Does not hinder the landing of the ship.

After unloading vehicle s in this way, deck washing is carried out again before loading the next vehicle s to be transported.First, the stopper handle is moved from the "deregulation position" to " Then, the operation of moving the winding handle from the “fixed position” to the “winding position” is repeated about two or three times. At this time, the winding handle performs this operation. At the end of the process, the compressed air is supplied to the pneumatic cylinder 29 at the `` winding position '', and the force for displacing the output portion 29a downward with a strong force is always applied to the belt 14. It works. As a result, the belt 14 is effectively tensioned, and the respective circular lids 34 are brought into water-tight contact with the corresponding upper peripheral edge of the upper end opening of the guide cylinder member 11. Under this condition, deck cleaning is performed, whereby washing water does not enter the four-way portion 8 from the close place between the circular lid 34 and the guide cylinder member 11. It is surely blocked.

The above embodiment can be modified as follows.

That is, it is preferable to apply a slip promoting material for smoothing the sliding movement of the belt 14 at a portion where the belt 14 is rubbed at a part of the upper end opening of the guide cylinder member 11. The pneumatic cylinders 29 and 31 may be hydraulic cylinders or air motors or electric motors having a power type rotating body for rotating the take-up shaft 13. Since 1 does not require a large output, it may be a solenoid. Then, instead of the rotation restriction releasing member 21, a power driving means for directly displacing the feed pawl 25 may be replaced.

FIG. 16 shows a further modification of the above embodiment.

The belt tension fixing device 7 shown in this figure is of a portable type, is lighter and smaller as a whole as compared with the previous embodiment, and the input lever 24 is directly oscillated by hand. The detent 27 is to be manually operated. At this time, when the input cradle 24 is fully swung to the return side (opposite to the belt winding side r 1), the rotation restriction releasing member 21 moves the feed pawl 25 to the wheel 23. The rotation of the winding shaft 13 toward the return side by the feed pawl 25 can be freely adjusted. When the rotation stop by the feed pawl 25 is released in this way, the detent pawl 27 is pushed downward by pressing the manual push button to operate against the resilience of the torsion coil panel. The restriction of the rotation of the winding shaft 13 to the return side by 19 is completely released, the rotation of the winding shaft 13 around the center is made free, and the winding shaft 13 is wound and stored on the winding shaft 13. Belt 14 will be drawn out arbitrarily. In addition, the input lever 24 is replaced with a hand and is of the above-mentioned power type, and is controlled collectively by an air motor having an air reserve tank in the piping system individually piped or by an electric motor. To do Good. In FIG. 16, substantially the same portions as those in the previous embodiment are denoted by the same reference numerals.

The above-described present invention is widely used, and for example, the present invention may be applied to a vehicle s such as a truck or a chassis. The present invention can be used for fixing to a vehicle, and the present invention can also be used to fix the vehicle loaded on the deck of a ship such as a car ferry to the deck. become able to. In this way, the present invention does not have to be applied to the deck of a ship.

In addition, the product of the present invention may be applied to the container body. In this way, the container can be easily lashed to a transportation platform without lashing equipment. Further, the present invention is applied to a gantry used for a front leg of a chassis or the like, and lashing of the chassis main body can be easily performed by fixing the gantry and the chassis main body by fitting uneven metal parts. Industrial applicability

According to the present invention configured as described above, the following effects can be obtained. That is, according to the method invention of the present application, the lashing is performed by the operation of hanging the tension cordage between the adjacent loads and the operation of pulling the corresponding tension cordage downward by the power tensioner. Can be implemented.

Also, when a load such as a vehicle s is fixed to a support side such as a deck f, even if the distance between the load s and the support side changes arbitrarily, a belt that can be pulled out between them can be changed in length. Thus, the belt 14 can be easily provided with a required amount of tension to the belt 14, so that the load s can be easily and reliably fixed to the support side, and the load and the support can be easily fixed. The versatility is improved by being able to cope with relatively large changes in the distance on the side. More specifically, since the winding shaft 13 is rotationally driven by the expansion and contraction operation of the pneumatic cylinder 29 to wind and tighten the belt 14, a large number of belts 14 are identified by remote control. It is possible to easily apply a large amount of tensile force, and to rotate the winding shaft 13 via the boosting feed rotation mechanism 18 so that the belt 14 has a specific size. The driving force of the output portion 29a of the pneumatic cylinder 29 when applying a tensile force of 20 mm can be reduced, and the winding shaft can be freely rotated by the winding shaft rotating mechanisms 20 and 21. Since the winding is performed by power, it is possible to easily make the large number of winding shafts 13 freely rotatable at once by remote control.

In addition, since each part of the present invention is present in the recess 8, the upper surface opening of the recess 8 is covered by a covering means such as a frame-shaped cover 37 so that the worker can move on the floor f. The cargo _s can be moved smoothly, and the cargo _s can be fixed efficiently, which contributes particularly effectively to the lashing of many vehicles s on the deck f of the ship. Things.

In addition, the regulation of the rotation of the take-up shaft 13 by the half-rotation regulating means 19 and its release and the regulation of the rotation of the take-up shaft 13 by the double feed rotation mechanism 18 and its release are released by the regulation release driving means (pneumatic pressure). Remote control via the cylinder 3 1) and the regulation release member 2 1 enables the large number of winding shafts 1 3 to be freely rotatable, and the belt 1 4 Can be quickly pulled out from the belt holding portion 12 and passed over the load and the support side.

In addition, it is possible to easily carry the package to an arbitrary place and fix the load and the support side with the belt 14 simply and quickly. In addition, since the rotation of the winding shaft 13 by the feed pawl 25 of the booster feed rotation mechanism 18 is released by the displacement of the input lever 24, the winding shaft 13 can be rotated freely. In this case, the manual operation is sufficient by releasing only the rotation restriction of the rotation half-regulating means 19. Further, in a state where the winding shaft 13 is freely rotatable, the belt 14 is wound around the winding shaft 13 by the winding force of the belt winding force applying means 17 so that the lashing is performed. The labor is reduced, and the belt 14 is wound on the winding shaft 13 by the winding force of a relatively inexpensive spring, and the maintenance work is reduced. Can be.
