Fully enclosed and insulated steel module is equipped with sliding door, large safety glass windows on all sides and roof. Signal horn, cab space heater, front and roof windshield wipers, air conditioning, dome light, sun visor and shade, fire extinguisher and air circulating fan are standard. Optional: tilt cab. Optional: nylon protective window covers.

Engine

Cummins Model QSL 8.9 liter diesel, 6 cylinder, 253 kW (340 BHP) @ 1800 governed RPM. Includes engine block heater (120 V), air heater starting aid (24 V), oil heater starting aid (120 V), high silencing muffler, radiator and fan. Multiple hydraulic pump drive transmission provides independent power for all machine functions. Two 12 volt maintenance-free, Group 8D batteries, 1375 CCA at -18°C (0° F), 24 volt starting and 70 amp alternator. One 568 l (150 gal) capacity diesel fuel tank, mounted on right side of upperworks, with level indicator in operator’s cab.

Hydraulics

Our closed-loop system provides a separate hydraulic circuit to power each crane function. The result is truly independent, variable-speed operation of the swing, load hoist, boom hoist, and travel functions.

Hydraulic System

Six high-pressure piston pumps are driven through a multi-hydraulic pump transmission. These six pumps provide independent “closed loop” hydraulic power for front drum, rear drum, boom hoist system, swing system, and both left and right crawler operation. Hydraulic reservoir capacity is 300 l (79.25 gal) and is equipped with breather, sight and electrical level indicator, clean out access, and internal diffuser. Each function is equipped with relief valves to protect the hydraulic circuit from overload or shock. A replaceable, ten micron (absolute) full flow tank filter is furnished in the hydraulic circuit. All oil is filtered prior to return to the hydraulic reservoir. The hydraulic system also includes a pump transmission disconnect clutch and hydraulic oil cooler.

Drums

Two equal width winches are driven by independent variable displacement axial piston hydraulic motors through planetary reduction mounted on separate front and rear shafts with anti-friction bearings. Drums are grooved for 26 mm rope. Powered hoisting/lowering operation is standard with automatic (spring applied, hydraulically released) multi-disc brakes and a drum rotation indicator. Optional features include free-fall operation for front and/or rear drum(s) and an auxiliary (third) hydraulic powered drum mounted in the boom butt, which includes a third drum control system. The auxiliary drum is used as the luffing hoist when the machine is equipped with a luffing jib. Preparation for the auxiliary drum includes electric wiring, controls, hydraulic selector valve, and plumbing.

Boom Hoist

The independent boom hoist consists of a drum grooved for 22 mm diameter wire rope and includes 22 mm diameter wire rope for 20 part line reeving. The drum is powered by a variable displacement hydraulic motor coupled to an internal brake and planetary gearbox equipped with a ratchet and pawl.

Swing System

The high strength fabricated steel alloy rotating bed is mounted on a 2.76 m (108-9/16”) diameter turntable single-row ball bearing. The independent swing is powered by a fixed displacement hydraulic motor coupled to a planetary gearbox with an internal brake. The swing system has a maximum speed of 2.3 rpm.

Carbody

The carbody connects the rotating bed to crawler assemblies. It is a high strength fabricated steel assembly with a FACT™ connection system for fast installation and removal of crawler assemblies.

Crawlers

Crawler assemblies are 8.3 m (27’ 2”) long with 1.22 m (48”) wide cast steel crawler pads. Each crawler is identical and can be mounted on either side of the carbody. Each crawler is powered independently by a variable displacement hydraulic motor and includes two hydraulically powered pin actuators for fast installation and removal from the carbody. The carbody mounted drive motors are connected to the crawler final reduction via telescoping shafts, allowing crawlers to be removed without opening their hydraulic circuits. Crawlers provide ample tractive effort that allows counter rotation with a full rated load, achieving a maximum ground speed of 1.8 kph (1.1 mph). An optional self-erect system includes carbody jacking cylinders with pads, controls, a 27.2 t (30 USt) assembly block, boom-butt installation support, gantry cylinders, and a crawler handling chain.

Controls

Modulating electronic-over-hydraulic controls provide infinite speed response directly proportional to control lever movement. Controls include Manitowoc’s exclusive EPIC® Electronically Processed Independent Control system providing microprocessor driven control logic, pump control, on-board diagnostics and service information. Block-up limit control is standard for hoist and whip lines. Rated Capacity Indicator system (RCI) is standard for main boom and upper boom point. “Function cut-out” or “warning only” operation is available via programmable configuration. Travel and swing alarms are standard.

No. 76 Heavy-Lift Main Boom

The liftcrane is equipped with a 20 m (65.6’) No. 76 basic heavy-lift tubular chord boom consisting of a 5.5 m (18’) butt, 5.5 m (18’) insert, and 9 m (30’) top with seven 76.2 cm (30”) diameter roller bearing sheaves in 3 sheave packs. It includes rope guides, boom hoist wire rope, and a boom angle indicator. The No. 76 boom utilizes steel suspension straps and Manitowoc’s exclusive FACT™ connection system, which consists of two hooks, two horizontal connection pins, and alignment pads for each boom connection location. A powered boom hinge system, including cylinder, piping, operating controls, and locking device, is standard. Additionally, luffing jib preparation is included as standard.
