ROUGH TERRAIN CRANES Ӏ SECTOR SPOTLIGHT
from 9–16 m, while a bi-fold
swingaway jib extends reach to 67m. It can achieve a maximum capacity of 715kg when working at its maximum radius of 46m. For pick-and-carry operations 15.2t can be handled at 3.5m with the boom fully retracted. It has Grove’s MAXbase variable
outrigger system, a 12-inch CCS 1+ touchscreen display, a wider full-vision tilting cab, and a new carrier design. Like the GRT765 it has Grove Connect telematics and fleet management and oCSI. The standard 7,938kg of counterweight can be supplemented with an optional 1,360kg for greater strength; either configuration is compatible with the optional hydraulic counterweight removal system for fast and easy self-assembly. “The GRT780 is a great
demonstration of the productivity, advantages customers get with the latest generation of Grove rough-terrain cranes,” says Daniele Montanaro, product manager for rough-terrain cranes at Manitowoc. “We are looking forward to producing this model in our Niella Tanaro factory. It’s a great option for customers in both European and emerging markets equipped with the latest Cummins Stage V engine to support its impressive strength improvements while delivering cleaner, more efficient operation.”
HIGH END At the top end of the lifting capacities on display at Bauma was the 130 tonne class LRT1130-2.1 from manufacturer Liebherr. The crane is Liebherr’s most
recent rough terrain model since its re-entry to the rough terrain market. It was first seen as a prototype at Bauma 2022 and was also our cover star on the March 2023 issue (when it was officially launched).

Liebherr’s LRT1130-2.1
The LRT1130-2.1 has a
maximum load capacity of 130 tonnes, a 60m telescopic boom, a maximum hoist height of 85m, and a 66m maximum radius. At the start of this year Liebher sold one LRT 1100-2.1 and LRT 1130-2.1 to South African company T3 Projects. To complement the RTs it also bought an LTM 1300-6.3 mobile (all terrain) crane. The LRT 1100-2.1 has a
maximum load capacity of 100t, a 50m telescopic boom, a maximum hoist height of 69m, and a maximum radius of 54m. T3 Projects specialises in mining and infrastructure projects and handles all the processes from planning, the entire erection process and commissioning. It employs over 900 people in South Africa, Mozambique, DR Congo, Ghana and Burkina Faso. “As we often work in harsh conditions, we rely on high-quality, robust and powerful equipment,” says Donovan Carroll, operations director at T3 Projects. “LRT rough terrain cranes are known for their advanced safety systems, which
helps us to achieve our goal of maximising safety on all projects. At the same time, their simple operation ensures additional safety and increases efficiency. “The cranes are easy to
transport and set up, which saves a considerable amount of time and resources on sites. This will improve our overall project and cost efficiency. We are delighted that we will be able to handle a wider range of projects with the new cranes.”
As the global construction landscape evolves rough terrain cranes remain an important resource in the construction lifting toolkit. They may not grab the headlines like some other crane types but they remain dependable workhorses of jobsites worldwide. Their off-road agility, compact
size, and pick and carry capabilities make them indispensable across oil fields, infrastructure projects and rugged environments. At Bauma and beyond their evolution is quietly but clearly on display. They may not always get the spotlight… but in the world of lifting they are the unsung heroes.
