Tower Crane Heavy-duty Support Welding Project: This welding workstation utilizes two-axis positioners and employs dual robots for welding tower crane bases simultaneously. The welding setup of the dual robots consists of a gantry structure with overhead rails (X/Y/Z axes) and a cantilever structure (X/Z/rotational axis). All axes are external to the robots and can be synchronized with robot movements for welding. Both robots can work independently or in conjunction with the positioners. The gantry is equipped with a two-level platform for storing welding power supplies, wire spools, and other items, facilitating inspection and maintenance by personnel.
