GRT8100

Manitowoc has introduced two new Grove rough-terrain cranes: the 100-ton GRT8100, and the 88-ton GRT880, both featuring Manitowoc’s Crane Control System (CCS).

Debuting Grove’s new naming system (GRT= Grove rough-terrain), the GRT8100 and GRT880 are generational updates to the popular RT890E and RT880E models, respectively.

“These new Grove models reflect everything we’ve learned in the last decade of crane design,” said Mike Herbert, global product director of rough-terrain cranes at Manitowoc. “For example, customers will find the new cranes even more reliable thanks in part to the advances brought by our Product Verification Center (PVC). Each component has undergone extensive component validation and prototype testing and with that knowledge, we’ve been able to improve these cranes from the ground up.”

The 100-ton-capacity Grove GRT8100 has exceptional reach with its 154-ft. full-power, five-section telescoping boom that has a maximum tip height of 160 ft. Adding its maximum length of lattice boom extension raises the maximum tip height of 252 ft. The boom is lighter and longer than its predecessor, but can lift heavier loads throughout the load chart.

The 88-ton-capacity GRT880 features a 134-ft. telescopic boom that is also lighter than the GRT8100 boom. Customers will find this boom especially useful for the mining sector, equipment maintenance, and infrastructure projects.

With increased capacity at mid range and maximum radii, the GRT8100 and GRT880 are more versatile than competitors’ cranes – they boast 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, the cranes enable customers to lift heavier loads to greater heights, helping companies compete for - and win - bids for projects they may not have been able to previously.

The GRT8100 is the only crane in its class to offer a hydraulic luffing jib that can be configured at lengths from 33-56 ft. Other optional boom extensions for the cranes include a 33-56 ft. manual offsettable bi-fold boom extension with fixed offsets at 0°, 20° and 40°, as well as a heavy-duty 10-ft. jib that can be offset to 40°.

A new boom-extension stowage system for both cranes’ hydraulic and offsettable jib options decreases erection and stowage time by 60%, compared with previous generation Grove cranes. That enables operators to set up and disassemble the cranes in less time, saving money and increasing return on investment.

The GRT8100 and GRT880 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 GRT8100 and GRT880 will surely increase ROI for customers with the versatility of their long booms and strong load charts,” Herbert said. “Also their hydraulic and crane control systems are designed with efficiency and improved fuel economy in mind. Combined with the heightened reliability improvements brought by our PVC, the new cranes will enable customers to be more efficient and decrease maintenance and operating costs. Rental companies will surely see this benefit, too, as they will generate better rental rates.”

 

Crane Control System (CCS)

Both cranes feature Manitowoc’s Crane Control System (CCS). The standardized CCS is a user-friendly interface that Manitowoc is introducing on all new rough-terrain crane models, as well as crawler cranes, all-terrain cranes, boom trucks and tower cranes. 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.

 

The intuitive nature of CCS enables operators to more quickly set up their cranes and get to work.   Additionally, CCS offers the new ECO mode to improve fuel efficiency and decrease wear and tear on the powertrain and hydraulic systems.
