Cabinet crane control
February 1st 2011

A compact AC drive with built-in crane control functions has been launched by ABB for side-by-side installation within crane cabinets. The low voltage AC drive ACS850, with crane control program, can be preconfigured for use in standalone cranes. Typical applications include new and retrofit tower cranes in hoist, trolley and slew motions and industrial cranes in hoist, trolley and long travel motions. Working in conjunction with the drive's motor control platform, DTC (direct torque control), the crane control program provides smooth speed and torque control of the crane.

Operating time is minimised and lifting capacity optimised through the crane control program's load speed control, which maximises the hoist speed for a given load.
