Modular Drive Systems

At the heart of Control Techniques crane systems are Unidrive SP Modular AC drives. These compact flexible power devices are capable of driving loads of up to 1.9MW and yet each module is compact and light enough enough to be easily handled on site, simplifiying installation and maintenance.  They can be configured to provide redundancy and fault tollerance so that cranes can continue to operate, even if a module ever failed.

Control Techniques’ Crane Management System (CMS)

Control Techniques’ CMS monitors physical and operating conditions of the crane on a real time basis. It can be used to operate the crane, schedule maintenance, analyse crane faults and provide crane production data.

Differential Global Positioning System (DGPS)

Control Techniques’ DGPS is a GPS based automatic steering and yard management system for port applications, which can be used on both RTG and RMG cranes. The system offers satellite guided relative positioning (differential) mode, giving excellent accuracy with minimal positioning error.
