Problems solved by technology

The entire tensioning process is completed manually. Since the operating position is higher than the ground, and the ratchet tensioning device is far from the trolley's hanging basket, it is difficult to operate and the safety is difficult to guarantee. In addition, the luffing rope is 20' long The degree of tightness will vary with individual operators, and the effect is difficult to guarantee

Abstract

The invention provides a crab trolley, a crab trolley luffing system of a crane with the crab trolley, and a crane. The crab trolley comprises a frame (11), and further comprises a first winding drum (12) pivoted on the frame (11), and a second winding drum (13) arranged in linkage with the first winding drum (12), wherein the central axis of the second winding drum (13) is parallel to or collinear with that of the first winding drum (12). The technical scheme of the invention is convenient to automatically control tension of a luffing rope so as to improve the tension effect.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a trolley and a trolley luffing system of a crane equipped with the trolley, and the crane. Background technique [0002] The luffing mechanism is one of the working mechanisms of the tower crane. It is to meet the requirements of the material loading and unloading work position, make full use of its own lifting capacity (the reduction of the amplitude can increase the lifting capacity), realize the working mechanism of changing the amplitude, and use it to improve the tower crane. working range, improve production efficiency. According to the movement form, the luffing mechanism can be divided into the boom swing type luffing mechanism and the trolley type luffing mechanism. The advantage of realizing the luffing through the trolley is that the material moves horizontally during the luffing, and the installation is convenient; the speed is fast, the power is saved; the effe...
