The electrical control system of the gantry crane on the dam crest adopts Schneider PLCs. Each mechanism uses ABB’s AC880 series frequency converters. The Kunlun Tongtai touch – screen is used to monitor the entire equipment. This equipment is applied to the first – phase reclamation project of Wenzhou Oufei, which is the largest single – unit reclamation project in China.
Electrical control system for the 2×800KN mobile gantry cranes on the dam crest of Cao’e River
In this system, the auxiliary hoisting, gantry, and trolley mechanisms all adopt the conventional rotor – series resistance control method. The main hoisting mechanism selects two ACS800 frequency converters from ABB to control two hoisting motors respectively. By controlling the…
