After the crawler crane is assembled, the crawler crane needs to be subjected to a maximum lifting capacity debugging test, wherein the maximum lifting capacity debugging test comprises three grades, namely: base arm operating mode maximum lifting capacity, 110% maximum lifting capacity and 125% maximum lifting capacity.

According to the requirements of GB/T14560-2016 crawler crane, the crawler crane needs to carry out the debugging test of the maximum lifting capacity, 110% of the maximum lifting capacity and 125% of the maximum lifting capacity of the working condition of the basic arm. To complete the test, a crane is required to hoist the tooling beam. The tooling beam can be hung with weights at multiple points. By the arrangement, the weights can be stacked in double rows or multiple rows, so that the height of the weights is reduced, and the operation is safer and more reliable.

The pulley mount 2 is fixed to the beam body 1. The first pulley block 3 is mounted on the pulley mounting seat 2. The hoist 4 is attached to the beam body 1 with respect to the center of the beam body 1 in the longitudinal direction.

The tool beam is welded by steel plates to form a box, and the inside of the tool beam is hollow so as to reduce the weight of the tool beam.

The pulley mounting seat 2 can be mounted at the middle of the length direction of the tooling beam in a pin shaft mode. In order to facilitate the installation of the pulley mounting seat 2, a mounting plate 5 is welded at the top of the middle of the tooling beam. The mounting plate 5 comprises two blocks arranged side by side. The longitudinal direction of the mounting plate 5 is the same as the longitudinal direction of the beam body 1. The mounting plate 5 is provided with a mounting hole 51, and the pulley mounting seat 2 is mounted in the mounting hole 51 of the mounting plate 5 through a pin shaft.

In some embodiments, the height of the middle portion of the beam body 1 is greater than the height of the two ends of the beam body 1. I.e. H1 has a height greater than H2. The first pulley block 3 is to be installed at the middle part of the beam body 1, the middle part of the beam body 1 is higher, and the two ends of the beam body 1 are shorter, so that the bearing performance of the beam body 1 is better, the beam body 1 is higher in bearing larger area and smaller in bearing small area, and the weight of the beam body 1 is lighter. In the caterpillar crane debugging test process, the bearing capacity is mainly provided by the weights, and the tooling beam mainly plays a role in bearing the weights, so that the weights can extend out of the caterpillar of the crane, and the safety of hoisting the weights is improved. And the shape and load condition of the weight are more in line with the actual working condition of the crawler crane.

In some embodiments, the thickness of the beam body 1 is the same along its length. The thickness direction of the beam body 1 is perpendicular to the longitudinal direction L and the height direction H shown in the drawing.

Referring to fig. 1, in some embodiments, the first pulley arrangement 3 comprises a plurality of pulleys arranged side by side. The pulleys are arranged side by side to play a role in changing the multiplying power of the steel wire rope, so that the steel wire rope is easier to hoist.
