8500-1 Manitowoc crane - load chart, specs & dimensions (2017 - 2018)

Operator's Cab

Totally enclosed, full vision cab fitted with tinted safety glass and an opening front window. It features a fully adjustable, high-backed seat with arm rests, short handle control levers, and an electronic twist grip hand throttle. Additionally, an air conditioner, a signal horn, and a windshield wiper are standard. The lighting includes: 2 - Front flood lights 1 - Cab inside light. A new easy-to-read LMI and maintenance display serves as a safety device.

Retractable crawlers

Crawlers can be extended and retracted for better jobsite maneuverability. On some models, these crawlers can also ship attached for easier transport and quicker setup.

Working weight

Approximately 75,100 kg (165,600 lb) including upperworks and lowerworks, full upper counterweights, full carbody counterweights and 12,2 m (40') basic boom.

Weight Considerations

Weight of hooks, hook blocks, slings and other lifting devices are a part of the total load. Their total weight must be subtracted from the rated load to obtain the weight that can be lifted.

Energy saving systems

Green-Engine mode conserves fuel during full speed drum operation under load, at a lower engine RPM. Other available options include Green-Winch Mode and Auto Idling Stop Mode.

Controls

Full-flow hydraulic control system for constant variable pressure to front and rear drums, boom hoist brakes and clutches. Controls respond instantly to the touch, delivering smooth function operation.

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 boom hoist circuit, and can accommodate an optional third circuit. Another is used in the left propel 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.

Drums

Front and rear drums for load hoist powered by variable displacement piston-type motors, driven through planetary reducers. Powered hoisting/lowering and free-fall operation is standard. Drum turn indicators for front and rear drums are also standard. Brakes: spring set, hydraulically-released, multiple-disk holding brake is mounted on the hoist motor and is operated through a counter-balance valve. An external ratchet is fitted for locking the drums. Drums: (front and rear) 545 mm (21.5") P.C.D. x 550 mm (21.7") wide drums, grooved for 22.0 mm wire rope.

Swing System

Swing unit: Powered by a hydraulic piston-type motor driving spur gears through planetary reducers, the swing system provides 360° rotation. Swing brake: A spring-set, hydraulically released multiple-disk brake is mounted on swing motor. Swing lock: 4-Position lock for transportation. Rotating bed turntable: Single-row ball bearing with an integral internally cut swing gear. Swing speed: 4.0 rpm.

Crawlers

Crawler assemblies can be hydraulically extended for wide-track operation. Crawler belt tension is adjusted with a hydraulic jack and maintained by shims between the idler block and frame. 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 maintenance-free operation.

Gantry

This high folding type gantry is fitted with a sheave frame for boom hoist reeving. Hydraulic lift is standard. It provides full up, full down positions.

Boom

Welded lattice construction using tubular, high-tensile steel chords with pin connections between sections. Two idler sheaves and four point sheaves are standard. Basic boom length 12,2 m (40') consists of the boom butt section 5,8 m (19') and boom top section 6,39 m (21'). Optional boom inserts are available to provide extension capabilities. They also have welded lattice construction with tubular, high-tension steel chords and pin connections on each one of the 3,0 m (10'), 6,1 m (20'), 12,2 m (40') inserts. Maximum total length of boom 61,0 m (200').
