Manitowoc has launched two new Grove rough-terrain cranes that promise to set new standards for the 65-ton and 80-ton classes.
Alongside improved strength and reach, the GRT765 and GRT780 deliver improved operator comfort and easier servicing inside a compact design. Deliveries of the first units began in the second half of 2024, after the new models were presented for the first time at Manitowoc’s Crane Days event in May.
“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. The operators will love the comfort of our new, wider cab as well as the expanded CCS display,” said John Bair, Product Manager for rough-terrain cranes at Manitowoc.
“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 manoeuvrer around busy jobsites.”
Grove delivers more power
The Grove GRT765 replaces the RT765E-2 in the current rough-terrain crane lineup. It offers a 65-ton maximum capacity and a 38.4-metre 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 47.2 metre five-section full-power boom.
Both models feature a 35-56 ft bi-fold swing away jib which can be manually offset up to 45 degrees.

For the GRT765 there is 6,894 kg of counterweight, while the GRT780 comes with 17,500 lbs, although customers can boost this to 7,938 kg for even greater strength. Both cranes can add a hydraulic counterweight removal system as an option and powerful line pull is guaranteed, with both models offering 7,784-kg on a single line for fast set-up and operation.
Transport and set-up are centered around convenience. Both cranes typically travel as one load, with the GRT765 weighing about 42,638 kg. The GRT780 weighs 45,132 kg, or 46,493 kg with the heavy counterweight.
The overall width of both cranes is 3 metres, nearly 30-cm narrower than typical cranes in these classes. Set-up is compact, and owners have greater flexibility with the MAXbase variable outrigger system, which gives increased lift capacity and asymmetric configurations to easily fit on congested sites.
Grove Connect
The rough-terrain cranes are the first to offer the Grove Connect telematics and fleet management system launched in 2022.
For the operator, there’s a 7.5-cm wider, full-vision cab that tilts to 20 degrees and comes with a three-camera system for better visibility.
Operations can be managed via the new, bigger 30-cm touchscreen CCS display that offers controls and layout that are common across the Manitowoc product line.
For technicians, the cranes include on Crane Service Interface for enhanced diagnostics and service, while centrally located service points on the superstructure and carrier make routine maintenance easier.
