Abstract

The invention relates to a crane. Crane comprises: boom (1), is used for hanging weight; Pulley assembly (2), is connected with boom (1), and pulley assembly includes first fixed pulley (21), second fixed pulley (22) and for The bearing part (23) carrying the first fixed pulley (21) and the second fixed pulley (22); the first lifting drive part (7), including the first hook for connecting the first end of the weight and for The first rope body that pulls the first hook up and down, the first rope body is wound on the first fixed pulley (21); and the second lifting drive part (8), including the second end for connecting the second end of the weight. The suspension hook and the second rope body used for pulling the second suspension hook up and down, the second rope body is wound around the second fixed pulley (22). Applying the technical solution of the present application, the first hook and the second hook are respectively connected to the two ends of the heavy object, so the crane in this embodiment can independently hoist the bar-shaped heavy object.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a crane. Background technique [0002] figure 1 It shows the principle diagram of hoisting a strip-shaped heavy object in the prior art. Such as figure 1 As shown, at present, two or more cranes 10 are required to operate simultaneously for a weight 20 that is slender in shape or heavy at one end. Simultaneous operation of multiple cranes 10 has higher requirements on the work site, and the cost of hoisting also doubles. [0003] Further, since each crane 20 needs to be equipped with an operator, and each operator's operation level and reflection are inconsistent, which will lead to inconsistent lifting actions, which may cause damage to the hoisted objects, and some even cause rollover. [0004] For multiple cranes hoisting a heavy object, the weight of the hoisted object should be ≤ 0.8 × the sum of the rated load of each crane. The lifting capacity of the crane is no...
