Definitions

  • the present invention relates to an equipment for lashing containers stacked on the deck of a ship.
  • each of the containers 2 is subjected to a horizontal force f 1 , f 2 , f 3 and a vertical force v 1 , v 2 , v 3 by the oscillation (rolling) of the ship as shown in FIG. 5(b).
  • a racking force R 1 expressed by Eq. 1 is created on top of the lowest-tier container by the horizontal forces f 1 , f 2 and f 3 . Accordingly, the container is deformed into a diamond shape, and if the deformation exceeds an allowable strength of the container itself, the container is crushed.
  • R 1 f 1 + f 2 + ( 1 / 2 ) f 3
  • the vertical forces v 1 , v 2 and v 3 develop a compressive force V 1 at a corner of the container, and if compressive force V 1 exceeds an allowable compressive strength of the container body, the container is crushed.
  • a lashing rod 6 and a turnbuckle 7 connected to the rod 6 via a joint a are installed between a lashing eye plate 4 on the hatch cover top face 1 and a container corner metal 5, which are located on a diagonal line, by which the container 2 is lashed.
  • the aforementioned racking force R 1 is reduced to R 1 ' expressed by Eq. 2 by the horizontal component Tcos ⁇ of a tension T created on the lashing rod 6 and the turnbuckle 7, by which the container is prevented from being crushed.
  • R ′ 1 R 1 ⁇ T cos ⁇ where ⁇ is a tension angle of the turnbuckle 7 (lashing angle) shown in FIG. 6(b).
  • the horizontal component Tcos ⁇ of the tension T also acts in the direction such as to reduce the aforementioned container overturning force V 2 , by which the container overturning force V 2 is decreased.
  • the decreased container over turning force V 2 ' is given by Eq. 3 according to the ratio of a container height H to a container width B.
  • V 2 ′ V 2 ⁇ T cos ⁇ ⁇ ( H / B )
  • V 1 ′ V 1 ⁇ T cos ⁇ ⁇ ( H / B ) + T sin ⁇
  • case A shows the results of calculation on the second-tier container lashing means shown in FIG. 8
  • case B shows the results of calculation on the third-tier container lashing means shown in FIG. 9.
  • the stowage weight in case A is 111.0 tons (five tier stowage) and 92.75 tons (six tier stowage), and the stowage weight in case B is 133.6 tons (five tier stowage) and 111.5 tons (six tier stowage).
  • an on-deck arrangement of container lashing equipment comprises a plurality of lashing bridge pillars to be erected on the deck of a ship to lash containers stacked on the deck between the lashing bridge pillars and a lashing bridge with an upper horizontal walkway for the workers lashing the containers. Furthermore, it comprises a plurality of first attachment members (lashing eyes) for lashing mounted on the lashing bridge pillars, a plurality of first tightening members (lashing rods), one end (the lower end) of which is to be attached to a first lashing eye on the pillar and the other end (the upper end) is to be attached to an upper corner metal of a container to be lashed so that it is directed under a steep angle upwardly.
  • the first lashing members For allowing a more stable and reliable stacking of containers in addition to the first lashing members it comprises a further plurality of second tightening members (lashing rods), one end of which is to be attached to a second lashing eye mounted on the pillars in substantially the same level as the first lashing eyes and the other end (the upper end) is to be attached to a lower corner metal of the container.
  • Two standard heights of containers should be accommodated. Therefore, the height of the first and second lashing eyes on the pillars for the first and second lashing rods should be halfway between the two mentioned standard heights.
  • the substantially horizontally extending lashing rods thus might extend slightly downwards when the container stack (or the lowermost container) has the lowest standard height (8.5 feet) or extend slightly upwards when the they have the greatest standard height (9.5 feet).
  • an object of the present invention is to provide an on-deck arrangement of container lashing equipment in which in lashing containers stacked on the deck of a ship, the arrangement of tightening means is contrived so that a force component in the direction such as to pull up the container is created, whereby the container can be prevented from being crushed, and the tightening means can be made small in size and light in weight.
  • the on-deck arrangement of container lashing equipment in accordance with the present invention comprises a plurality of lashing bridge pillars for erection on the deck of a ship to lash containers stacked on the deck; a plurality of attachment members mounted on said lashing bridge pillars for lashing thereto; and a plurality of tightening members, an upper end of each being adapted to be attached to one of said attachment members, a lower end of each being adapted to be attached to a lower corner metal of a container stowed between the lashing bridge pillars whereby in use all tightening members that are attached between the pillars and the containers extend slantwise downward, toward said deck of the ship.
  • the attachment members are positioned on said lashing bridge pillars such that a lashing angle that the tightening direction of each tightening member makes with the horizontal plane is set in the range of 5 to 35 degrees, thereby providing an increased force component in a direction acting to pull up the container.
  • the lashing angle may preferably be in the range of 25 to 35 degrees.
  • the on-deck arrangement of container lashing equipment in accordance with the present invention is preferably characterized in that the tightening member is composed of a lashing rod and a turnbuckle or only a turnbuckle.
  • the tightening member whose one end (upper end) is attached to the attachment member for lashing mounted on the lashing bridge pillar erected on the deck of the ship extends slantwise downward, and the other end (lower end) of the tightening member is attached to the corner metal of the container. Therefore, due to the tightening action caused by the shrinkage of the tightening member, an upward component of the tightening force acts in the direction such as to pull up the container, so that the compressive force at the container corner, which has so far presented a problem, can be decreased, thereby preventing the container from being crushed.
  • the length of the tightening member can be decreased significantly as compared with the case of the lashing angle of 45 degrees and larger of the conventional tightening member, by which a small-sized, lightweight tightening member can be provided.
  • the tightening member is composed of the turnbuckle only, and the lashing rod connected to the conventional turnbuckle via the joint is omitted. Thereby, the number of required parts is decreased, and the construction is simplified, so that lowered cost and reduced maintenance can be achieved.
  • the on-deck container lashing equipment in accordance with the present invention achieves the following effects.
  • FIG. 1 is a front view of an on-deck arrangement of container lashing equipment in accordance with a first embodiment of the present invention
  • FIG. 2(a) is a front view showing a case where the equipment shown in FIG. 1 is applied to containers stacked on a hatch cover top face
  • FIG. 2(b) is a front view schematically showing a state in which the containers shown in FIG. 2(a) are subjected to ship oscillation.
  • FIG. 3 is a front view of an on-deck container lashing equipment in accordance with a second embodimentof the present invention
  • FIG. 4 is an enlarged perspective view showing an essential part of the equipment shown in FIG. 3.
  • a plurality of lashing bridge pillars 8 are erected on the deck of the ship, and a lashing eye plate 4 is mounted on the pillar 8 as an attachment member for lashing.
  • a lashing angle ⁇ which the tightening direction of the turnbuckle 7 constituting the tightening member makes with the horizontal plane, is set in the range of 5 to 35 degrees, preferably in the range of 25 to 35 degrees.
  • the lashing rod 6 and the turnbuckle 7, constituting the tightening member, are connected to one another via a joint a.
  • FIG. 2(a) shows the case where the above-described on-deck container lashing equipment is used to lash the containers 2 stacked on a hatch cover top face 1.
  • the symbols in FIG. 2(a) are used as in the case of FIG. 1.
  • FIG. 2(b) shows the state in which the containers 2 shown in FIG. 2(a) are subjected to ship oscillation (rolling).
  • the vertical component T"sin ⁇ of the tension T" acts advantageously on a compressive force V 1 " as is expressed by Eq. 5.
  • V 1 ′ ′ V 1 ⁇ T ′ ′ cos ⁇ ⁇ ( H / B ) ⁇ T ′ ′ sin ⁇
  • the stowage weight is 161.2 tons for five tier stowage and 121.5 tons for six tier stowage. That is, the lashing means shown in FIG. 1 can ensures a stowage weight 30% or more heavier than that of the conventional second-tier lashing means shown in FIG. 8.
  • the length of the tightening member can be decreased significantly as compared with the case of the lashing angle of 45 degrees and larger of the conventional tightening member, by which a small-sized, lightweight tightening member can be provided.
  • FIG. 3 is a front view thereof
  • FIG. 4 is a perspective view thereof.
  • the plurality of lashing bridge pillars 8 are erected on the deck of the ship, and the lashing eye plate 4 is mounted on the pillar 8 as an attachment member for lashing.
  • the turnbuckle 7 serving as a tightening member, which extends slantwise downward and the other end (lower end) of which is attached to the corner metal 5 of the container 2 stowed between the lashing bridge pillars 8.
  • the lashing rod 6 and the joint a in the above-described first embodiment are omitted. That is, since the length of the tightening member is decreased significantly as compared with the conventional tightening member by setting the lashing angle in the range of 5 to 35 degrees, it is necessary only that a rod portion of the turnbuckle 7 be lengthened slightly.
  • the second embodiment also achieves the same operation and effects as those of the above-described first embodiment. Further, since the tightening member is composed of only the turnbuckle owing to the decreased length of the tightening member, the number of required parts is decreased, and the construction is simplified, so that lowered cost and reduced maintenance can be achieved.
