Local Talent and Smart DC Drives Deliver the Goods

The largest cargo-handling and container terminal in Atlantic Canada, Halterm Ltd., Port of Halifax, Nova Scotia, turned to its local Control Techniques distributor for a complete retrofit of one of its cranes, an older DC Gen-Set that had been damaged by a fire. Halterm offers complete terminal services for the global shipping industry. Its system of nine gantry cranes operates 24/7/365, handling over 200,000 teu's (shipping containers) per year, and provides a direct inter-modul link from cargo vessels to trucks and rail lines.

Control Techniques has years of experience in cranes and hoists, and is a leader in this market. Its innovative digital technology also provided the most cost effective solution for the DC retrofit. However, Halterm not only wanted a cost-effective, state-of-the-art solution, but the people and service that would make the solution work. Control Techniques was selected over two major drive vendors, because Halterm knew it would get more than boxes of drives and controls dropped at the door by its distributor. It knew their CT distributor would be there to work with their people--the power engineers, mechanical engineers, and control engineers, to see the job through start to finish.

Digital DC Drives — Smart, Rugged and Reliable

Control Techniques developed the first digital DC drive nearly 20 years ago. With the addition of advanced circuitry and components, more powerful software, and enhanced communications capabilities, the third generation of that drive is available today in the Mentor II and Quantum III.

Although AC drive technology has advanced, DC drive technology has remained simple, rugged, robust, and the most cost-effective solution for regenerative applications. Coupled with its capacity for delivering 100% torque at zero speed and smooth speed and torque control, demand for DC drives remains strong in several industries--metals and plastic, wire and cable, and a wide range of materials handling and conveyance applications.
