Manitowoc’s all-new GRT8100 launches the manufacturer’s Grove rough Terrain line.
The 90tonne GRT8100 is an update of the RT890E and has a 47m boom with a maximum tip height of 49m. With a full complement of boom extension and insert options, the crane has a reach up to 77m. The boom is lighter and longer than its predecessor, but has the ability to lift heavier loads.
“Customers will find the new crane more reliable thanks in part to our Product Verification Centre in Shady Grove, Pennsylvania, US,”

“Customers will find the new crane more reliable thanks in part to our Product Verification Centre in Shady Grove, Pennsylvania, US,” said Mike Herbert, global product director of rough-terrain cranes at Manitowoc. “Each component has undergone extensive component validation and prototype testing.”
With increased capacity at mid-range and maximum radii, the GTR8100 has up to 16% greater capacity at full radius, 13% greater capacity in mid-range applications and 27% greater capacity at close radii. With offsettable boom and fly extensions, customers can lift heavier loads to greater heights.
Manitowoc said the GRT8100 will be the only crane in its class to offer a hydraulic luffing boom extension. The bi-fold hydraulic boom extension can be configured to 10m to 17m lengths. Other optional boom extensions for the GRT8100 include a 10m to 17m manual offsettable bi-fold boom extension with fixed offsets at 0, 20 and 40 degrees, as well as a heavy-duty 3m jib that is offsettable to 40 degrees.
A new boom extension stowage system for both the GRT8100’s hydraulic and offsettable jib options decreases erection and stowage time by 60% when compared with previous generation Grove cranes.
The GRT8100 will also have best-in-class line pulls at 7,883 kg on both the main and the auxiliary hoists. The stronger pull results in fewer parts of line being needed to lift loads, which will lead to increased productivity on the job site and faster customer payback.
The crane has Manitowoc’s Crane Control System while the updated cab features a new ergonomic jog dial and new joysticks. CCS enables operators to more quickly set up their cranes and offers the new ECO mode feature to improve fuel efficiency and decrease wear and tear on the powertrain and hydraulic systems.
