Hydraulic System
All three variable displacement piston-type pumps are driven by a heavy-duty pump drive. One of these pumps is used in the right propel circuit and hook hoist circuit, and can accommodate an optional third circuit. Another is used in the left propel circuit, boom hoist circuit and hook hoist circuit. The third variable displacement pump is used in the swing circuit. In addition, two gear pumps are used in the control system and auxiliary equipment, and two gear pumps serve the brake cooling system.

Swing lock: 2 Position lock for transportation.
Rotating bed turntable: Single-row ball bearing with an integral internally cut swing gear.
Swing speed: 4.0 rpm
Boom Support System:
Single drum powered by a hydraulic axial piston motor through a planetary reducer.
Brake: A spring-set, hydraulically released multipledisc brake is internally fitted in the boom hoist motor and operated through a counter-balance valve. An external ratchet is fitted for locking the drum.
Drum: Single drum, grooved for 16 mm (5/8") diameter wire rope. Boom Hoist reeving is 12-part line.
Gauges
Fuel gauge, engine water temperature gauge, hour meter and tachometer are located on the monitor display.
Warning display
All potential warnings, including battery charge, engine oil pressure, air cleaner, engine oil filter, control main pressure, and hydraulic oil temperature will appear on the monitor display when a fault occurs.
Safety device
Function lock lever, anti-two-block, boom over hoist limit switch, boom angle indicator, signal horn, boom hoist drum lock, front and rear drum lock, swing lock, swing alarm (buzzer and lamps), boom backstops and load moment indicator.
Operator's Cab:
Totally enclosed, full vision cab fitted with tinted safety glass. A fully adjustable, highbacked seat with arm rests permits operators to set their ideal working position. Side mounted console for auxiliary controls and instruments. An air conditioner, a signal horn, cigarette lighter, windshield wiper and inspection lamp socket are standard features.
Controls
In front of operator are the foot pedals for front, rear and third drum (optional) brakes and foot throttle pedal. At operator's right side are the travel (propel) control levers and the function lock lever. To the operator's right front are the boom hoist control lever, front and rear winch control levers and the free-fall select switches for the front and rear winches and drum turn indicators (front /rear drum). To the operator's left front are the swing control lever and third drum (optional) control lever. To the operator's left are the crawler extend/retract lever and the positive swing lock. The left hand console contains toggle switches for travel (propel) speed, free-fall high/low select, gantry control, crane/clamshell select switch and the anti-two-block/boom overhoist switches. Directly in front of the console are the drum pawl lock for boom, front, rear and third drum (optional) and the engine ignition key. The swing parking brake and signal horn are mounted on the swing control lever.
Lowerworks
Carbody:
The durable carbody features steel welded construction with extendible axles.
Crawlers:
Crawler assemblies can be hydraulically extended for wide-track operation or retracted for transportation. Crawler belt tension adjusted with hydraulic jack and maintained by shims between idler block and frame.
Crawler drive
The independent hydraulic propel drive is built into each crawler side frame. Each drive consists of a hydraulic motor driving a propel sprocket through a planetary gearbox. The hydraulic motor and gearbox are built into the crawler side frame within the shoe width. The track rollers are sealed for maintenancefree operation.
Crawler brakes
Spring set, hydraulically released, multiple disc-type parking brakes are built into each propel drive.
Steering mechanism.
The hydraulic propel system provides both skid steering (driving one track only) and counter-rotating steering (driving each track in opposite direction) and differential track speed.
Crawler shoes:
63 shoes per side, 914 mm (36") wide each crawler.
