Manitowoc increases strength, reach, and flexibility on new Grove rough-terrain cranes
Manitowoc has launched two new Grove rough-terrain cranes in the 65-ton and 80-ton size classes. The GRT765 and GRT780 also deliver operator comfort and easier servicing with a compact design. Deliveries of the first units will begin in the second half of 2024. The new models were presented for the first time to dealers and contractors at Manitowoc's Crane Days event in Shady Grove, Pennsylvania.
"Customers will immediately notice the significant improvements in reach and strength, but we've also packed a lot of other benefits into these new models," said John Bair, product manager for rough-terrain cranes at Manitowoc. "The operators will love the comfort of our new, wider cab as well as the expanded CCS display. We've also added the latest productivity and fleet management technology with our MAXbase variable outrigger positioning system and the Grove CONNECT telematics platform. Not to mention we packed all of this into a very compact and lightweight package, which makes this crane very easy to transport, as well as maneuver around busy job sites."
The Grove GRT765 replaces the RT765E-2 in Manitowoc's current rough-terrain crane lineup. It offers a 65-ton maximum capacity and a 126-foot four-section full power boom. The Grove GRT780 will replace both the RT770E and the GRT880 in the current rough-terrain crane lineup and offers an 80-ton maximum capacity with a 155-foot five-section full-power boom.
Both models feature a 35- to 56-foot bi-fold swingaway jib which can be manually offset up to 45 degrees. For the GRT765 there is 15,200 pounds of counterweight, while the GRT780 comes with 17,500 pounds, although owners can boost this to 20,500 pounds. Both can add a hydraulic counterweight removal system as an option. Both models offer 17,160 pounds on a single line for fast set-up and operation.
Transport and set-up are centred around convenience. Both cranes typically travel as one load, with the GRT765 having a GVW of approximately 94,000 pounds. For the GRT780, GVW is 99,500 pounds (102,500 pounds with the heavy counterweight). The overall width of both is just 9.8 feet – nearly a full one foot narrower than typical cranes in these classes. The set-up is compact, and owners have greater flexibility with the MAXbase variable outrigger system, which gives increased lift capacity and asymmetric configurations to fit on congested job sites.
The cranes are the first Grove rough-terrains to offer the Grove CONNECT telematics and fleet management system launched in 2022. For the operator, there's a three-inch wider, full-vision cab that tilts to 20 degrees and comes with a three-camera system for better visibility. Operations can be managed on a 12-inch touchscreen CCS display that offers controls and layouts that are common across the Manitowoc product line. For service technicians, the cranes include oCSI (on Crane Service Interface) for enhanced diagnostics and service, while centrally located service points on the superstructure and carrier make routine maintenance easier.
