Remote-control cable (6) can be connected to either the front or rear remote stations.
The remote control box (7) has an emergency shutoff button that halts all crane movement.
The pressure governor switch (8), remote manual valve sensor (9), and oil dispense dump
valve (10) are part of the electrical system.
HYDRAULIC SYSTEM
The cranes are completely hydraulic powered and their principles of operation are the same.
Individual control panel, boom and hydraulic cylinder arrangements, and lifting capacities
are different. All cranes are powered from the vehicle's hydraulic system.
All are equipped with outriggers for stability during operation. All cranes use a combination
of hinged joints and telescoping members to give them their motions. The hydraulic-
powered hoisting winch has an automatic brake to prevent accidental lowering of the load.
