US-headquartered crane manufacturer Manitowoc has launched two new Grove rough terrain cranes: the 65 ton capacity GRT765 and the 80 ton capacity GRT780. The cranes were shown at its customer and dealer event, Crane Days, at its Shady Grove HQ, in May. Deliveries of the first units are expected in the second half of 2024.

Boom lengths

The Grove GRT765 replaces the RT765E-2. It has a 126 ft four-section full power boom.

The Grove GRT780 replaces both the RT770E and the GRT880 and has a 155 ft five-section full-power boom.

Jib & counterweight options

Both models have a 35-56 ft bi-fold swingaway jib which can be manually offset up to 45˚. The GRT765 has 15,200 lb of counterweight, while the GRT780 has 17,500 lb – although customers can increase this to 20,500 lb if needed. Buyers can also specify a hydraulic counterweight removal system.

Line pull

Both models offer a line pull of 17,160 lb on a single line.

Transportability & setup

Both the new cranes can typically travel as one load, with the GRT765 having a GVW of approximately 94,000 lb. For the GRT780, GVW is 99,500 lb (102,500 lb with the heavy counterweight). Overall width of both is 9.8 ft.

Set-up is compact, says Manitowoc, is aided via the MAX-base variable outrigger system.

Connect telematics & cab control

The cranes are the first Grove rough terrains to offer Grove’s Connect telematics and fleet management system, which launched in 2022. For the operator there’s a three-inch wider, full-vision cab that tilts to 20˚ and comes with a three-camera system for better visibility.

Operations are managed via a new, bigger 12-in touchscreen CCS display that offers controls and layout that are common across Manitowoc’s product line.

Servicing access

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 are designed to make routine maintenance easier.

John Bair, product manager for rough terrain cranes at Manitowoc, said: “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. 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 jobsites.”
