Type 4017 AC Hoist Controller with
Compensated DC Dynamic Lowering


Type 4017 is a DC dynamic lowering hoist controller providing braking action by rectifying the voltage developed on the wound rotor motor slip rings and connecting the DC voltage to a single phase of the three phase wound rotor motor primary windings.  It is recommended for hoists with a fixed minimum load and do not have a mechanical or eddy current brake, but require good speed regulation.

Control in hoisting is the standard secondary resistor method.  In lowering 5 speed points are provided with the secondary slip voltage rectified and connected to a single phase of the primary.  The controller provides relatively float speed-torque curves similar to eddy current brake hoist performance.

Suitable for all NEMA and CMAA service classes
