Two new rough terrain cranes from Grove

At the 2016 Bauma exhibition in Munich, Grove introduced two new rough terrain cranes - GRT8100 and GRT880 - debuting the new naming system of GRT (Grove rough terrain). The new models are generational updates of the RT890E and RT880E models, respectively.

Mike Herbert, Manitowoc global product director for rough terrain cranes, said, “These new Grove models reflect everything we’ve learned in the last decade of crane design. For example, customers will find the new cranes even more reliable thanks in part to the advances brought by our Product Verification Centre (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 90 tonne GRT8100 has a 47 metre boom with a maximum tip height of 49 m. With boom extension and insert options, the reach is 77 m. The boom is lighter and longer than its predecessor but lifts more throughout the load chart. This will allow customers to get unparalleled usage out of a 90 tonne rough terrain crane, said the company.

The 80 tonne GRT880 features a shorter 41 m boom that is also lighter than the GRT8100 boom. Customers will find this boom especially useful in the mining sector, equipment maintenance, and infrastructure projects, Manitowoc explained.

According to the company, the GRT8100 is the only crane in its class to offer a hydraulic luffing jib that can be configured at lengths between 10 and 17 m. Other optional boom extensions include a 10 to 17 m manual offsettable bi-fold with fixed offsets at 0, 20 and 40 degrees as well as a heavy duty 3 m jib that is offsettable to 40 degrees.

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

Both cranes have Manitowoc’s Crane Control System (CCS). An updated full-vision cab tilts to 20 degrees and also has a new ergonomic control arrangement including a tilting steering column, electronic joysticks, and a jog dial for simple CCS menu navigation.
