AI Technical Summary
Existing telescopic boom cranes have difficulty in flexibly adjusting the lifting point position in complex factory environments, and the possibility of adjusting the lifting point position is low, which increases the difficulty of lifting.
A boom head connection structure for cranes was designed, including a boom body, a boom head, a first drive device, a ratchet mechanism, and a second drive device. The boom head can be rotated at any angle and automatically locked through the cooperation of the ratchet and pawl. Combined with the mechanical transmission structure, stepless angle adjustment is achieved, thereby enhancing the load-bearing capacity.
It enables flexible adjustment of lifting point positions in narrow spaces, expands the lifting range, reduces lifting difficulty, improves the load-bearing capacity of the boom head, extends equipment service life, reduces maintenance costs, and is simple and practical to operate.
