Konecranes Offers Speed Control Options for Crane Motors

Konecranes, Springfield, Ohio, has introduced two speed control options—extended speed range and adaptive speed range—for overhead lifting equipment motors for the power industry. The control options provide cost-effective solutions for achieving high average hoist speeds without increasing motor size.

The extended speed range has been developed for high duty applications where near capacity loads are routinely lifted. It uses inverter technology to allow increased hoist speed for light loads. The faster hoist speed allows operators to return empty hooks to position or move smaller loads with more speed and efficiency, reducing average hoist cycle time and increasing productivity.

Adaptive speed range automatically varies the speed of the hoist according to the load. For full capacity loads, Adaptive Speed Range forces a slower, more deliberate speed to enhance safe lifting. Moderate loads can be moved with additional speed, while light loads are afforded even more speed.

Designed for applications where high capacity lifts are performed less frequently, Adaptive Speed Range uses a compact motor, maximizing productivity and safety, while reducing unnecessary motor power and maintenance costs.
