18000 Manitowoc crane - load chart, specs & dimensions (2005 - 2020)

Vision operator’s cab

The Vision Cab™ is a fully enclosed and insulated steel module mounted to the left front corner of the rotating bed. The module is equipped with power tilt, a sliding door, and large safety glass windows on all sides and the roof. Standard equipment includes a signal horn, power seat, all-season climate control package, front and roof windshield wipers, dome light, sun visor and shade, fire extinguisher, swing and travel alarms, and a radio/CD player. Additionally, the operator’s station swings over the front of the rotating bed for transportation.

Engine

Cummins Model QSX 15 Diesel, 6 cylinder, 447 kW (600 BHP) @ 1800 governed RPM. Includes engine block heater (120V), ether starting aid, transmission disconnect clutch for cold weather starting, high silencing muffler, hydraulic oil cooler, radiator and fan. Multiple hydraulic pump drive transmission provides independent power for all machine functions. Two 12 volt maintenance-free batteries, 1 300 CCA at -18°C (0° F), 24 volt system and 75 amp alternator. One diesel fuel tank, 1 040 l (275 gal.), mounted on rear 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

Multiple high-pressure piston pumps, driven by a multi-pump transmission, provide independent closed-loop hydraulic power for the hoisting drums, boom hoist, swing, left crawler and right crawler. The hydraulic reservoir has a capacity of 1,188 l (314 gal.) and is equipped with a breather, clean out access, and internal diffuser. Each function is equipped with relief valves to protect the hydraulic circuit from overload or shock. The system includes an oil cooler and a replaceable, ten-micron absolute full flow filter. All oil is filtered before entering the hydraulic pumps.

Carbody

Connects the rotating bed and crawler frames. The fabricated steel rotating bed lower module mounts to a single-piece carbody by a 3 m (9’ 10”) diameter triple-row roller bearing turntable. Each crawler frame is mounted to the carbody with the FACT™ connection system power-actuated pins. Crawler drive motors are mounted on the carbody, permitting crawler removal without opening the travel drive hydraulic circuit.

Crawlers

Crawler assemblies are 11.81 m (38’ 9”) long with 1.52 m (5’) wide cast steel crawler pads and lubricated intermediate rollers. Each crawler is powered independently by two variable displacement hydraulic motors 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 drive shafts. Crawlers provide ample tractive effort, allowing counter-rotation with a full load rating. The maximum ground speed is 1.1 kph (0.7 mph).

Swing system

Bearing adapter-mounted independent swing is powered by a fixed-displacement hydraulic motor coupled to an internal brake and planetary reduction. Includes Manitowoc Patented swing lock. Two swing drives are required for standard machine configuration, while four swing drives are required for MAX-ER®. The swing system maximum speed is 1.2 rpm.

Mast hoist system

Single drum mast hoist mounted in rotating bed is powered by a fixed displacement hydraulic motor and a planetary reduction gear box with internal brake. Ratcheting pawl is standard and includes mast-hoist wire rope.

Boom support system

Moving Mast: The moving mast is 9.1 m (30’) long and connects to the fixed mast suspension rigging. When used with the optional self-erect package, the mast is utilized for crane assembly and disassembly, and it is capable of lifting and positioning the crawler assemblies. Fixed Mast: The stationary No. 56 lattice mast provides geometry to raise and support all boom lengths. A 30.5 m (100’) mast is standard for the basic crane, while a 42.7 m (140’) mast is required for MAX-ER® applications. The boom-hoist rope is reeved from the drum in the mast butt through sheaves in the mast top, and the boom-hoist equalizer forms 16-part boom-hoist rigging. High-strength steel straps connect the equalizer to the boom top, and both cushioned boom stop and automatic boom stop are standard.

The MAX-ER

The MAX-ER attachment components include: One 12.2 m (40') No. 56 insert, added to increase the mast length to 42.7 m (140'). Two additional swing drives (for a total of four) mounted on the rotating module. Each swing drive is powered by a fixed-displacement hydraulic motor coupled to a planetary reduction gearbox and internal brake. A wheeled or hanging MAX-ER counterweight assembly attaches to the top of the mast by steel straps and to the rear of the upperworks by a shearframe, and to the top of the moving mast by steel straps for the 12.1 m (40') counterweight position. The hanging MAX-ER counterweight is 18 m (59') behind the crane's centerline of rotation, while the wheeled MAX-ER counterweight is either 12.1 m (40') or 18 m (59') behind the crane's centerline of rotation. The wheeled counterweight uses large off-road tires, which can be positioned for traveling or swinging, and it also includes hydraulic support jacks and pads.
