Problems solved by technology

[0004] Due to the need to disassemble and assemble the weight 2 frequently, it is necessary to use an auxiliary crane to hoist the auxiliary counterweight 202' for each disassembly and assembly. The disassembly and assembly process is cumbersome, which reduces the work efficiency and increases the use cost of the crane

Abstract

The invention discloses a counterweight system of a crane, which comprises a main counterweight (201) fixedly connected with the upper main structure (4) of the crane and an auxiliary counterweight detachably connected with the main counterweight (201). The counterweight (202) also includes a self-detachable power assembly (1) detachably connected to the auxiliary counterweight (202), and the self-detachable power assembly (1) can move the auxiliary counterweight ( 202) Connect or detach the secondary counterweight (202) from the main counterweight (201). By using the self-disassembly and assembly power assembly (1) that comes with the crane to hoist the auxiliary counterweight, the combination and disassembly of the counterweight (2) are completed, which makes the disassembly process easier, improves work efficiency, and reduces use costs. The invention also discloses a crane including the counterweight system.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a counterweight system of a crane. Furthermore, the present invention also relates to a crane comprising the above-mentioned counterweight system. Background technique [0002] Crane is a widely used engineering machinery, which includes two states, please refer to figure 1 with figure 2 , figure 1 It is a schematic diagram of the hoisting operation state of the crane; figure 2 It is a schematic diagram of the traveling state of the crane. When in the hoisting state, in order to improve the stability of the whole machine, it is necessary to set a counterweight 2 with sufficient weight on the main body structure 4; Limit the weight of the counterweight. [0003] Please refer to image 3 , image 3 It is a structural schematic diagram of a counterweight system in the prior art. The main counterweight 201' and the auxiliary counterweight 202' are set, the main counter...
