come from gas, wind, or nuclear? And Scope 3 includes emissions from across the company’s entire supply chain. This last would include emissions from equipment used to construct new facilities for the company itself, or its suppliers. This will further push adoption
of electric equipment on many sites. So too will noise regulations. On many city sites operations cannot be carried out at night or the early morning due to noise. Tadano says that its new crane will emit lower noise when operating. This will result in significant advantages for customers, the company says, when working in congested urban areas with noise ordinances, completing lift projects at night, and operating indoors. The details of the new crane
are still firmly under wraps, at least until ConExpo. But it would perhaps be a reasonable guess that this crane will be somewhere around the 100t class, with a long boom, as this has been the focus of many recent crane launches.
ALL PURPOSE FOCUS The 100t class was the focus for Liebherr when it first re-entered the rough terrain market a few years ago after a decades-long absence. It’s perhaps the class that is most widely demanded by users and the direction of travel looks to be very much towards higher capacities and longer booms on two-axles. Ehingen’s first two new models
offered capacities of 90t and 110t. At ConExpo, it will be launching a new 130t model: the LRT 1130-2.1. This crane will be, the company says, the largest on two axles. The capacities of Link-Belt and Manitowoc Grove’s two-axles RTs, for example, both top out at 120t, with booms of 50m on the Kentucky-built 120|RT, and 60m on Manitowoc’s GRT8120.

GRT8100-1 brings the flexibility of the MAXbase variable support system to the 100t class
The new Liebherr will add 10t of capacity, compared to both these cranes, and feature a 60m long boom. This boom length is now very much the norm for telescopic cranes and looks likely to be a target for most new launches in the rough terrain class. The six-section Telematik
fast-extending boom can be supplemented with a 10.8m single folding jib or a 10.8–19m double folding jib. It is mounted at angles of 0°, 20° or 40°, or can optionally be hydraulically tilted from 0° to 40°. With an additional seven- metre lattice section as a telescopic extension, the new crane reaches
hook heights of up to 85m. The crane was first shown in
prototype at Bauma in October 2022. It will receive its official launch at ConExpo, and Liebherr says its primary focus will be the US market. Here, long journeys between sites, on roads with often highly variable vehicle weight and axle loading regulations, tilts the balance further in favour of the use of RTs over ATs, even for shorter jobs. And US users make heavy use of these cranes in pick and carry and tilt-up operations. But the crane has also been designed to be sold internationally. It can be transported economically
