The invention relates to a balance leg used for a small crane. The balance leg comprises a first-stage telescopic leg, a second-stage telescopic leg, a third-stage telescopic leg, a supporting leg anda foot drive. The second-stage telescopic leg is slidalby connected with a first sliding groove of the first-stage telescopic leg through a first sliding block. A first limiting mechanism is connected with the first-stage telescopic leg for limiting the motion stroke of the second-stage telescopic leg. The third-stage telescopic leg is slidalby connected with a second sliding groove of the second-stage telescopic leg through a second sliding block. A second limiting mechanism is connected with the second-stage telescopic leg for limiting the motion stroke of the third-stage telescopic leg. One end of the supporting leg is vertically connected with the end, away from the second-stage telescopic leg, of the third-stage telescopic leg through a connecting part. The other end of the supporting leg is fixedly connected with the foot drive. The first-stage telescopic leg is further provided with a bolt hole and connected with a chassis of the crane through a bolt. The balance leg is convenient to mount and dismount, and the small crane can be effectively prevented from rollover.
Description
technical field [0001] The invention belongs to the field of mechanical cranes, and more specifically relates to a balance foot for small cranes. Background technique [0002] At present, the outriggers used in cranes are all large hydraulic outriggers, which are too bulky to be installed on small cranes for power grid maintenance. Small cranes without outriggers have potential safety hazards in operation, which may cause the small crane to roll over during operation. It may even cause damage to substation equipment, affecting the normal electricity consumption of surrounding residents, and the resulting loss will be extremely large. Contents of the invention [0003] In order to overcome at least one of the above-mentioned defects in the prior art, the present invention provides a balance foot for a small crane, which is convenient for disassembly and assembly, effectively prevents the power grid from turning over when the small crane is in operation, and greatly improve...
