Liebherr/Mercedes diesel engine V-12 894 HP
(2) Main winch 33 ton with free fall, 2-speed. Compact design with internal, 2-speed planetary gear box, spring loaded and hydraulically released multi-disc holding brake, axial piston type hydraulic motor with variable displacement adjusts maximum hoisting speed depending on load, under utilization of full engine power. When the load is lowered the closed hydraulic circuit transfers back braking energy into drive train. When free-fall mode is selected the load is held or lowered by a wet multi-disc brake.
Winch contact roll consisting of a roller that is pressed to the drum with a spring, assuring correct winding on the drum on both main drums.
Winch synchronization option allows a synchronization of both winches. The line speed is the same for both winches.
Roller bearing slew ring with external teeth. Dual swing drives. Swing speed from 0-3.6 rpm variable with 3-speed ranges.
Automatic central lubrication of swing ring

15,400 lbs. Upperstructure counterweight & 7,700 lbs. lower works counterweight for maximum liftcrane rating – 150-US Ton. (Added: 2012)
All welded torsion resistant construction substructure consisting of carbody and two long B9 crawlers. Crawlers are maintenance free tractor type chain, robust 39” flat crawler pads, welded construction, mounted with bolts. Flat pads assure maximum ground protection when travelling and turning the machine.
Crawlers are quickly retractable from operation width to transportation width with 2 hydraulic cylinders operated by 2 hand levers on the carbody. Two independent axial piston hydraulic motors, spring loaded and hydraulically released multi-disc holding brake, and planetary gearbox. Crawler speed is continuously variable in both directions, each crawler with independent control so that counter rotation is possible.
For quick and clean assembly/disassembly of the crawlers the hydraulic lines are equipped with quick connections

Elevated cab (17.5’ eye level) The cabin elevation enlarges the operator's view over his working area. It is fabricated in box-design and elevates the cabin by 7 ft. and is pin connected. For ease of transport the operators cabin can be folded and pinned in the lower position for transport clearance. The box is equipped with a lockable door and can be used as storage space. For safe and comfortable access to the operator's cabin the elevation is equipped with a large pedestal with handrail and an access ladder with back protector.
Hydraulic power tagline winch 6,600 lbs. maximum proportional and adjustable line pull with freefall release
Rear drum working depth indicator measures the spooled on/off rope length with an incremental sensor on the winch taking into account the different layers on the drum. This length is indicated on the cab monitor and can be set to zero at any time
Catwalks both sides of machinery structure
Lighting Package Accessory includes:
(1) light in operators cab
(3) Adjustable spotlights facing front of machinery house
(3) Adjustable spotlights facing rear of machinery cab
Multiple lights within machinery house
Cold package -13°/-40°F The cold package enables operation of the machine in temperatures down to -13°F and storage of the machine with temperatures down to -40°F. The package consists of a diesel heater of 11 kW and a warm-up device for the hydraulic system. The heater can be started by a timer and warms up engine and operator's cabin. When the engine is running the warm-up device for the hydraulic system is activated and the system is brought to operation temperature.
Hydraulic oil, environmentally friendly
Litronic GSM service-modem
SWG control enables the operator to lower the slurry wall grab in a power lowering mode by using the brake pedals. This allows precise control of the lowering speed and thus prevents damage of the grab through hitting the ground as well as a wash-out of the slurry.
