The GRT880 comes with a 12,5 m to 41 m (41 ft to 134.5 ft) four-section, full power boom that provides unmatched lifting performance in its class. This combined with a strong permissible line pull, powerful hoists, Cummins QSB6.7L engine with ECO mode, load sensing hydraulic system and Manitowoc’s Crane Control System (CCS) ensure that the GRT880 will deliver unmatched efficiency on the jobsite. And just like all GRT models, we are so confident in the performance and reliability of the GRT880 that we are backing it with a two-year standard warranty.
Cab: The cab is designed with operator comfort and productivity in mind with full-vision design and 20° tilt for improved viewing at high boom angles. The tilt/telescoping steering wheel can be positioned for optimum use.
Control system: The new Crane Control System (CCS) offers a user-friendly interface, two full graphic displays mounted vertically for easier viewing and a jog dial for easier navigation and data input. The system allows the electronic controllers to be reprogrammed by the operator for specific speed and reaction. Parts commonality across Grove, Manitowoc and Potain product lines enhances operator familiarization and serviceability.
Boom: Lifting performance is enhanced by the 12,6 m – 41,1 m (41.2 ft – 134.7 ft) four-section, full-power boom with sequenced, synchronized extension capability
Backing up our promise: We stand behind our new line of GRT cranes, and we are willing to prove it. With new three-, four- or five-year extended warranty programs as well as a new two-year standard warranty; our GRT line of cranes are built to be GROVE REAL TOUGH.
