Abstract
The invention relates to an auxiliary arm system and a crawler crane. The auxiliary arm system comprises an auxiliary arm rear pull plate, an auxiliary arm support, an auxiliary arm, an auxiliary arm front pull plate and a main cargo boom. The auxiliary arm support is composed of a top section arm and a bottom section arm. The bottom end of the auxiliary arm, the bottom section arm of the auxiliary arm support and the top end of the main cargo boom are connected together. The two ends of the auxiliary arm rear pull plate are respectively connected to the bottom end of the main cargo boom and the top section arm of the auxiliary arm support. The two ends of the auxiliary arm front pull plate are respectively connected to the top section arm of the auxiliary arm support and the top end of the auxiliary arm. According to the auxiliary arm system, as torque on a hinge point of the auxiliary arm support from the auxiliary arm rear pull plate is small, the backward overturning torque of a boom system is reduced, the backward overturning possibility of the boom system is reduced, and the whole crane can be stable. Components of the auxiliary arm system are some components of a tower-type auxiliary arm system, and therefore the cost does not need to be increased, and the utilization rate of the crane structure is increased.
