1-12
Hydraulic System:
Standard:
Tandem pump, direct-driven by engine crankshaft, delivers 16 GPM (61 L/min)
at 3000 PSI (207 bar) and 32 GPM (121 L/min) at 3000 PSI (207 bar) at 2500
RPM governed engine speed. System protected by relief valves, suction line
strainer and 10-micron full-flow return line filter. 25-gallon (95 L) reservoir
equipped with filler cap and breather element.
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. Telescope cylinder and the boom elevation cylinder are equipped with
direct-connected holding valves. Boom angle indicator on side of boom.
Boom Rotation:
Standard:
Heavy-duty bearing rotation gear with external teeth supports boom. Rotation is
powered by hydraulic motor and worm gear drive. Rotation gearbox may be
adjusted as wear occurs to minimize backlash. Boom is attached by high
strength steel weldment.
Main Hoist:
Standard:
Turret-mounted, planetary gear hoist, is hydraulically powered to provide a bare-
drum line pull of 11,300 lbs (5200 kg) at a speed of 100 feet per minute (30.5
m/min). Hoist drum 11.65 inch (296 mm) diameter by 12.89 inches (327 mm)
long. Provides even pull and long cable life.
Main Hoist Rope:
Standard:
Main hoist rope is 9/16” (14 mm) diameter, Warrington-Seale construction, 6x36
classification, EIP grade, IWRC core, RRL lay, minimum breaking strength
35,000 lbs (156 kN), 140’ (43 m) long. Weight per foot is 0.6 lbs (0.9 kg per m).
Note that rope weight is not included in load calculations.
Boom Attachments:
Standard:
Anti-Two-Block Device:
Prevents damage to hoist rope and/or machine components from
accidentally pulling sheave block or downhaul weight against boom tip.
Consists of trip arm at boom tip , which is moved upward by sheave block or
downhaul weight as hook approaches boom tip. Trip arm actuates electric
switch , which is connected through cable reel mounted on boom to solenoid
dump valve in the hydraulic circuit. This valve will dump the HOIST RAISE,
TELESCOPE EXTEND, BOOM LOWER, SWING LEFT and SWING RIGHT
circuits. No other circuits are affected. These circuits are returned to normal
operation by operating the HOIST LOWER or TELESCOPE RETRACT
control.
