Abstract

PROBLEM TO BE SOLVED: To reduce the drive energy at the light work time and reduce a transportation cost, while having a boom attachment which can bear a heavy load. SOLUTION: An upper turning body 14 is placed on a lower travelling body 12 through a turning mechanism 13. Two boom attachments 15, 16 are installed parallelly in left and right on the upper turning body 14 and hooks 19, 20 are hung down on the booms 17, 18 respectively. The right/left booms 17, 18 are formed independently and respectively so as to be risen/fallen freely and the right/left hooks 19, 20 can also be wound up/down independently. At a heavy work, one load 39 is hung by right/left hooks 19, 20 and operated simultaneously by interlocking the boom attachments 15, 16. While, at a light load, only one side boom attachment is operated and a load is hung and a drive energy is saved.

2. Description of the Related Art In recent years,
With the increase in size of traveling cranes, the size and weight of boom attachments have become extremely large. Therefore, the boom attachment needs to be disassembled finely because it is overloaded when it is transported by land, and the transportation work is extremely complicated. In addition, when it is difficult to move by land, sea transportation is required, which takes time and increases transportation costs.

Further, even in the case of light work, since a huge boom attachment is operated, drive energy is wasted. Therefore, while having a boom attachment capable of withstanding a large load, a technical problem to be solved in order to operate with a small driving energy at the time of light work and to reduce the transportation cost arises. The purpose is to solve this problem.

Respectively, hooks 19 and 20 are suspended from the ends of the booms 17 and 18, respectively, and the ends of the booms 17 and 18 and the ends of the mast booms 21 and 22 are connected by pendant ropes 23 and 24. Further, the bail 27, 28 is attached to the left and right gantry 25, 26, and the boom / elevation ropes 31, 32 are wound around the bridle 29, 30 and the bail 27, 28.

The wire ropes 33 and 34 of the left and right hooks 19 and 20 and the boom raising and lowering ropes 31 and 32 are wound around the drums of the winch units 35 and 36, respectively, and the left and right hooks 19 and 20 are wound independently. In addition to being able to raise and lower, the left and right booms 17 and 18 are independently formed so that they can be raised and lowered.

A cabin 37 is provided on the right front part of the upper revolving structure 14, and a counterweight 38 is mounted on the rear part of the upper revolving structure 14. Thus, in heavy work, a large load is suspended by using the two boom attachments 15 and 16. As shown by the chain double-dashed line in FIGS. 1 and 2, one load 39 is hung by the left and right hooks 19 and 20, and the left and right winch units 35 and 36 are simultaneously driven to raise and lower the left and right booms 17 and 18. The load 39 is lifted and moved while controlling the angle and the heights of the hooks 19 and 20 to be equal.

As described above, according to the present invention, since two boom attachments are arranged side by side on the upper swing body, it is possible to suspend a load twice the design strength of each boom. Therefore, even with a traveling crane designed to suspend a large load, the boom can be reduced in weight without being large in size, and production costs and transportation costs can be reduced.
