Problems solved by technology

[0002] Since the quick-installation tower crane has a certain height when it is folded, the height of the trailer and the quick-installation tower crane exceeds the allowable height of the road during transportation, which makes the transportation of the quick-installation tower crane difficult
And due to the poor stability of the cross arm, tower crane collapse accidents frequently occur

Abstract

The invention discloses a rapid-assembly tower crane with a cross arm hydraulic folding mechanism. The rapid-assembly tower crane with the cross arm hydraulic folding mechanism comprises a first arm section and a second arm section which are connected through the cross arm hydraulic folding mechanism. The cross arm hydraulic folding mechanism comprises a folding hydraulic cylinder arranged on thesecond arm section, and the folding hydraulic cylinder is connected with a folding triangular plate. The folding triangular plate is connected with a forearm drive rod and a first connection plate ina shaft manner, the other end of the forearm drive rod and the other end of the first connection plate are connected to the two ends of the second connection plate in a shaft manner correspondingly.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a quick-install tower crane with a horizontal arm hydraulic folding mechanism. Background technique [0002] Since the quick-installation tower crane has a certain height when it is folded, the height of the trailer and the quick-installation tower crane exceeds the height allowed by the road during transportation, which makes the transportation of the quick-installation tower crane difficult. And due to the poor stability of the cross arm, tower crane collapse accidents frequently occur. Contents of the invention [0003] Purpose of the invention: The technical problem to be solved by the present invention is to provide a quick-install tower crane with a horizontal arm hydraulic folding mechanism for the deficiencies of the prior art. [0004] In order to solve the above technical problems, the present invention discloses a quick-install tower crane with a horizontal arm hydra...
