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...
