Lifting Magnet Controllers |
Class 6815 Type A Lifting Magnet Controllers
|
These controllers are designed to handle the large inductive currents switched during magnet operations. The Type A Magnet Controllers are
designed for 31-130 ampere, generator-powered magnets. Applications include crawler cranes, mobile cranes, locomotive cranes, and DC
generator-powered overhead traveling cranes.
Features:
Uses LINE-ARC® Type M mill-type contactors
Reliable, simple circuitry, easy to maintain
Adjustable reverse current by rheostat inside the enclosure

Class 6815 Type MF Magnet Controllers with Fanning Control
|
Type MF controllers have an additional slow-discharge circuit, activated by a separate Fan push button. This feature allows the operator to
visually control the dropping of all or part of the load, depending on the length the time the push button is held depressed.
Features:
Uses LINE-ARC® Type M mill-type contactors
Tabweld® mill type discharge resistor
Reverse-current adjustable within enclosure
Rectifier or generator power supply is completely isolated from magnet discharge
