STAHL CraneSystems presents in the SHA wire rope hoist a new, flexible motor concept for light industrial cranes.
The wire rope hoists in the SHA range combine the advantages of frequency-controlled hoist and travel motors (FU) with an adaptive speed range (ASR):
Stepless speed adjustment and smooth starting make work easier and reduce the stress on the crane system.
The adaptive speed control speeds up the lifting and lowering process to three times standard speed if the load is 10 % maximum load or less.
With higher loads the hoisting speed is adapted to the actual load on the hook. The SHA uses less power due to the lower output, reducing stress on the power supply and conserving valuable resources.
The SHA comes into its own in production environments where lower loads are lifted frequently, however a higher lifting capacity is required for occasional applications. A flexible range of applications and an excellent price-performance ratio make the SHA wire rope hoist an attractive alternative to the SH series of wire rope hoists.
