Crane drive and Control Retrofit
A crane’s drive becomes obsolete after 15 to 20 years due to advances in power electronics and controls. Obsolete spare parts are also an issue. Retrofitting new drives will hence extend crane lives, increase crane reliability and improve safety.
Portek’s complete turnkey package includes design and engineering, drive system assembly, installation, and commissioning. We strive for meticulous project planning and execution that minimizes downtime, so cranes can be returned to service after 14 to 30 days of on-site installation and commissioning. By increasing motor power, gearbox power and reducing gear ratio, we can obtain an end-benefit of speed increase to the main hoist and trolley of up to 25%.
