TYPE 4015 RECTIFIED DYNAMIC LOWERINGFOR HOIST SERVICE
All the advantages of a dc hoist controller on an
ac crane:
Rugged dc series wound mill motor.
Reliable dc series wound brake
Time-proven dc dynamic lowering hoist
circuit.
High-speed hoisting and lowering of empty
hook or light loads.
Slow, stable hook speeds hoisting and
lowering with all loads.
Reliable dc dynamic lowering with motor
connected as a generator and loaded with
the dynamic braking resistor.
"Off point" braking because of spring-
closed dynamic braking contactor.
The complete hoist control system consists of a
power transformer, a silicon bridge rectifier and
the hoist controller with accessories.
The power transformer is a totally
enclosed, nonventilated (TENV), three-
phase unit with delta connected primary
and a three-phase wye-connected
secondary.
The rectifier unit is a three-phase full wave
bridge with diodes in parallel for
redundancy. Rectifier protection is
provided by fuses in each leg and a surge
suppressor and snubbing circuit on the dc
side. Output of the rectifier is 300V dc.
The hoist controller is standard dc dynamic
lowering controller arranged for operation
from 300V dc power. The controller
components are all front-mounted, front-
removable, and front-wired.
A hoist control system with rectifier output of
360V dc is available as an option. Such a
system operates at higher speeds than the
300V dc system, resulting in a reduced duty
cycle time of about 15%.
Suitable for all NEMA and CMAA service
classes.
Recommended for: NEMA service Class I,
CMAA service Classes A1, C, D, E, F
