Description

Technical Field

[0001] The utility model relates to the technical field of crane counterweights, in particular to a counterweight pressing device. Background Art

[0002] Counterweight is the key to determine the lifting capacity of the crane. In order to adapt to different working conditions, the counterweight of the crane is generally set in the form of a combination of multiple counterweight blocks. When in use, multiple counterweight blocks are first stacked and placed, and then the counterweight blocks are limited and clamped through a clamping device to ensure the stability of the counterweight blocks during crane operation.

[0003] At present, the counterweight block clamping device needs to use more bolts for installation when installing the counterweight block. Since the counterweight block needs to be frequently disassembled and assembled during use due to transportation needs, it causes problems such as troublesome disassembly and assembly and increased workload. Based on this, we propose an improved counterweight block clamping device. Utility Model Content
