Abstract

The embodiment of the invention provides a counterweight device and a crane. The counterweight device comprises a counterweight assembly and a supporting assembly, wherein the counterweight assembly is connected with a rotary platform of the crane; one end of the supporting assembly is connected onto the counterweight assembly or the rotary platform; and the other end of the supporting assembly is supported on the ground. Through the structural arrangement, the supporting assembly can form supporting between the counterweight assembly and the ground or between the rotary platform and the ground. Therefore, the whole crane can be effectively prevented from tilting backwards, and the stability of the crane is greatly improved. Furthermore, the phenomenon that the rotary platform and a slewing bearing are damaged due to the fact that the whole machine tilts backwards is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a counterweight device and a crane. Background technique [0002] When the crane is working with a long arm and a heavy load, the moment of tipping forward is very large. It is usually necessary to install a balance counterweight at the tail of the slewing platform to balance the forward moment. However, if the balance counterweight is too large, it will cause the whole machine to tilt backward under no-load or light-load conditions. On the one hand, it will affect the stability of the crane; . Contents of the invention [0003] The invention provides a counterweight device and a crane, which are used to solve the problem that the whole machine will tilt backward under the no-load or light-load working conditions of the existing crane, so as to prevent the whole crane from tilting backward and improve the stability of the crane. Sex, and effectively protect the effect of the ...
