The invention provides a tower body of a tower type crane with a foldable telescopic arm. The tower body of the tower type crane with the foldable telescopic arm comprises a first telescopic arm, a second telescopic arm, a first connecting rod and a luffing mechanism, the first telescopic arm is formed as a rod body which is telescopic in the axial direction of the upper end; the second telescopicarm is formed as a rod body which is telescopic in the axial direction of the lower end, the upper end of the second telescopic arm is movably connected with the upper end of the first telescopic arm, so that the first telescopic arm and the second telescopic arm are switched between a folded position and an unfolded position, when the first telescopic arm and the second telescopic arm are in thefolded position, the second telescopic arm is arranged in parallel with the first telescopic arm, when the first telescopic arm and the second telescopic arm are in the unfolded position, the upper end of the first telescopic arm is oppositely arranged with the upper end of the second telescopic arm, and the first telescopic arm is coaxial with the second telescopic arm; and the luffing mechanismmoves to drive the first telescopic arm and the second telescopic arm to be switchable between the folded position and the unfolded position. The tower body of the tower type crane with the foldabletelescopic arm has a large rising height and is convenient to be transported.
Description
technical field [0001] The invention relates to the technical field of cranes, in particular to a tower crane with foldable telescopic arms. Background technique [0002] In the prior art, the tower body of the crane is large in size and weight, and the length of the telescopic arm is not easy to change, which is not convenient for different operation requirements.
