The GRT8100 and GRT880 rough-terrain cranes replace the RT890E and RT880E, respectively. The 90-tonne GRT8100 has a 47-meter boom and a maximum tip height of 49 meters. The 80-tonne GRT880 has a 41-meter boom. The GRT8100 has a hydraulic luffing jib that can be configured at lengths between 10 and 17 meters. A boom extension stowage system decreases erection and stowage time by 60 percent, the company says.
Both cranes have Manitowoc’s Crane Control System (CCS). An updated full-vision cab tilts to 20 degrees and also features a new ergonomic control arrangement including a tilting steering column, electronic joysticks, and a jog dial for simple CCS menu navigation.
