HYDRAULIC SYSTEM - Continued

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.

The crane hydraulic system is a part of the main hydraulic system on the M985 E1/GMT.

The main hydraulic system is powered by a PTO-driven hydraulic pump and fluid stored in

the main fluid reservoir.

The crane hydraulic system consists of cylinders, lines, and valves controlled by the main

control valve. There are six different sizes of cylinders and other components used on the

crane.

Hydraulic lines and inline valves (1) provide fluid transport and control of crane functions.
