Abstract

The invention relates to the technical field of engineering machinery, in particular to an auxiliary arm of a crane and the crane. The auxiliary arm comprises an auxiliary arm main body, a wheel shaftand an arm head pulley block, the auxiliary arm main body is provided with an arm head, the wheel shaft is arranged on the arm head, the arm head pulley block is arranged on the wheel shaft, the auxiliary arm further comprises a supporting seat, wherein the supporting seat is fixed on the arm head so as to support the wheel shaft. The auxiliary arm of the crane and the crane aims at solving the technical problem that the stress concentration of the matching part of a pulley shaft and the arm head is solved to a certain extent due to the fact that a steel wire rope spins.

Description

technical field [0001] The present application relates to the technical field of engineering machinery, in particular to a crane jib and the crane. Background technique [0002] According to the size of the turntable space, the crawler crane can adopt the design of single-lift hoisting mechanism or double-lifting hoisting mechanism. Since a hoisting hoisting mechanism is usually equipped with only one hoisting wire rope, the single hoisting hoisting mechanism adopts a single hoisting wire rope, and the double hoisting hoisting mechanism adopts the configuration of double hoisting wire ropes. When the crawler crane adopts the design of the double hoisting hoisting mechanism, usually two steel wire ropes can be used at the same time under the long-arm or super-long-arm working conditions, and only a single steel wire rope can be used under the relatively short working conditions of the jib. [0003] Such as Figure 7 and 8 As shown, traditionally, crawler cranes can use jib ...
