Hydraulic System:
Standard:
Tandem pump mounted to rear end of hydrostatic piston pump which is
driven by the engine crankshaft. Delivers 6 gpm (23 L/min) at 2,600 psi
(179 bar) for boom circuits and 17 gpm (64 L/min) at 2,250 psi (155 bar) for
hoist circuit. System protected by relief valves and two 10-micron filters.
Hydraulic reservoir with 14 gallons (53 L) capacity.
Boom Assembly:
Standard:
Three section, high strength steel construction, equipped with bearing pads
for efficient support and extension. Double-acting hydraulic cylinders extend
boom sections. The primary extension cylinder and the double-acting boom
elevation cylinder are equipped with direct connected holding valves. Boom
angle indicator provided on both sides of boom.
Boom Hoist:
Standard:
Turret mounted, planetary gear hoist is hydraulically powered to provide
bare-drum line pull of 5,000 pounds (2268 kg) and a line speed of 86 ft/min
(26 m/min). Hoist includes 85 feet (26 m) of 3/8 inch (9.5 mm) wire rope,
downhaul weight, swivel hook, and sheave block for 2-part line. (Required
for lifts over 4,000 pounds (1814 kg).) Sheave block weight is 60 pounds
(27 kg). Downhaul weight is 40 pounds (18 kg).
Optional:
Extra-long Wire Rope:
140 foot (42.6 m) long load line instead of standard 85 foot (26 m).
Net Weight:14 pounds (7 kg)
Boom Swing:
Standard:
Heavy-duty ball bearing rotation gear with external teeth supports boom.
Rotation is powered by hydraulic motor and worm gear drive. 360 degree
continuous rotation.
Boom Attachments:
Standard:
Anti-Two-Block Device:
Has electric solenoid dump valve which prevents damage to hoist rope and
machine components from accidentally pulling load hook against boom tip.
This valve will dump the HOIST RAISE, TELESCOPE EXTEND, BOOM
LOWER, and SWING LEFT RIGHT circuits. No other circuits are affected.
These circuits are returned to normal operations by operating the HOIST
LOWER or TELESCOPE RETRACT control. This system uses a trip arm to
activate switch.
