Quick stop for electric chain hoists
Liftket has developed the first electronically controlled chain hoist with quick stop function.
The Star VFD stops without ramp-down immediately after the control button is released. Therefore, loads can be lifted or lowered to the desired level in one go. No longer is there a need for time-consuming stop-and-go, which today still is a common way to position loads with increased precision.
The new series comprises hoists for loads from 125 to 2000kg. With nominal speeds up to 36m/min depending on the load, these chain hoists are much faster than comparable products on the market. Moving with no load, they can be operated with up to 200% of the nominal speed. This also saves a lot of time in everyday operation, since typically half of all runs are empty runs. And even apart from that, hoists are mostly operated with partial load.
The speed of a Star VFD can be increased accordingly when the nominal speed is not fully utilised. This standard series provides customers with cost-efficient, fast hoists for heavy use and large-volume applications.
