Series 8000L Crane & Hoist System

The series 8000L AC Flux Vector Crane and Hoist System provides you with the ultimate solution in hoist technology. By integrating advanced servo technology with Crane & Hoist features, the Series 8000L System provides the solution for the most demanding hoisting applications.

In addition to providing servo performance for any standard AC induction motor, the control can be powered from either an AC or DC power distribution system. Whether your application is new or retrofit, in material handling, steel, pulp and paper or forest products, the Series 8000L is the right choice for your lifting needs.
