Abstract

The invention relates to the technical field of revolving cranes, specifically to a telescoping revolving crane. With tidy wiring of cables, normal operation of a telescopic boom is guaranteed. The telescoping revolving crane comprises a pedestal, on which a revolving seat is installed. A telescoping lazy arm and a support arm for supporting the telescoping lazy arm are installed on the revolving seat. the telescoping lazy arm comprises a fixed arm and a movable arm which sleeves the fixed arm, and is characterized in that the lateral part of the fixed arm is provided with a horizontal driving cylinder, a piston rod of which is connected to the lateral part of the movable arm; two first suspension rings are installed on a cylinder body of the horizontal driving cylinder; the piston rod of the horizontal driving cylinder is equipped with a second suspension ring; and a cable extends out of the fixed arm and successively bypasses the first suspension rings and the second suspension ring and finally is connected to an electric control component inside the piston rod of the horizontal driving cylinder.

Description

technical field [0001] The invention relates to the technical field of slewing cranes, in particular to a telescopic slewing crane. Background technique [0002] Crane refers to a multi-action lifting machine that vertically lifts and horizontally transports heavy objects within a certain range. It is common equipment in ships, construction sites and other places. Among them, hydraulic slewing cranes are common. Moreover, in order to meet various needs, they are also used. A retractable boom will be provided, and the boom drive is generally driven by an oil cylinder, and cables are necessary. Due to the large number of cables, the wiring is disordered, which affects the telescopic operation of the telescopic boom. SUMMARY OF THE INVENTION [0003] In order to solve the above problems, the present invention provides a telescopic slewing crane whose cables are neatly wired to ensure the normal operation of the telescopic boom. [0004] The technical solution is as follows: ...
