RT 880 E (4x4x4) Grove crane - load chart, specs & dimensions (2008 - 2016)

Load moment and anti-two block system

Standard “Graphic Display” load moment and anti-two block system with audio-visual warning and control lever lockout. These systems provide electronic display of boom angle, length, radius, tip height, relative load moment, maximum permissible load, load indication and warning of impending two-block condition. The standard Work Area Definition System allows the operator to pre-select and define safe working areas. If the crane approaches the pre-set limits, audio-visual warnings aid the operator in avoiding job-site obstructions.

Sheaves and Boom Nose

Four nylon sheaves mounted on heavy-duty tapered roller bearings with removable pin-type rope guards. The quick-reeving type boom nose is designed for efficiency. Additionally, there is a removable auxiliary boom nose with a removable pin type rope guard.

Outrigger system

Four hydraulic telescoping single-stage double box beam outriggers with inverted jacks and integral holding valves. The system features a three-position setting: 0%, 50%, and fully extended. All steel fabricated, quick-release type round outrigger floats have a diameter of 775 mm (30.5 in). The maximum outrigger pad load is 56,700 kg (125,000 lb), and an outrigger monitoring system comes standard.

Swing

Two speed, planetary swing drive with foot-applied multi-disc wet brake. Spring applied, hydraulically-released swing brake. Single position mechanical house lock, operated from cab. Maximum speed: 2.0 rpm.

Axles

Front: Drive/steer with differential and planetary reduction hubs rigid-mounted to frame. Rear: Drive/steer with differential and planetary reduction hubs pivot-mounted to frame.

Oscillation Lockouts

Automatic full hydraulic lockouts on rear axle permits 25.4 cm (10 in) oscillation only with boom centered over the front.

Brakes

Full hydraulic split circuit brakes operating on all wheels. Spring-applied, hydraulically released parking brake mounted on front axle.

Cab

For improved operator comfort and visibility of the boom load, the cab can be tilted up to 20°. 20° tilt, full-vision, all-steel fabricated with acoustical lining and tinted safety glass throughout. Deluxe seat incorporates single-axis hydraulic controllers. Tilt/telescoping steering wheel with various controls incorporated into the steering column. Other standard features include: hot water heater, cab circulating air fan, sliding side and rear windows, sliding skylight with electric wiper and sunscreen, electric windshield wash/wipe, fire extinguisher, seat belt, air conditioning, and dual cab mounted work light.
