Swiss firm Clausen Kran expands fleet with the first Liebherr LRT 1090-2.1 rough terrain crane in the country, plus a Liebherr LTM 1150-5.3 mobile crane.

Brig, Switzerland-based crane rental company Clausen Kran AG has expanded its fleet with two Liebherr cranes: an LTM 1150-5.3 mobile crane and an LRT 1090-2.1 rough terrain crane. The rough terrain is the first model in the country.

Clausen plans to use the LTM 1150-5.3 for the assembly and disassembly of construction cranes, plus for operations in chemical plants where large lifting heights are required.

According to Liebherr, the crane’s light weight of 31 tonnes (with the boom dismantled and sliding beams removed) also make it well-suited for power stations and cable car projects with weight-limited access. The light weight also makes it easier to obtain special permits for the routes to be travelled, Liebherr added.

The LTM 1150-5.3 has a 66-metre telescopic boom which Liebherr says puts it on a par with crane types in the 200-tonne capacity class. Liebherr stated that the crane has a large radius and a high lifting capacity with a steep boom.

It has a total weight of 60 tonnes and an axle load of 12 tonnes and carries nine tonnes of ballast, so it can do many jobs without requiring the transportation of extra ballast.

According to Liebherr, the LRT 1090-2.1 rough terrain crane has been designed with a high degree of safety in mind. Standard equipment includes sliding beam monitoring to automatically detects the support status – on tyres or supports – and transfers it to the crane control. The LRT also comes with the variable supporting base VarioBase as standard. The two-axle crane has a maximum lifting capacity of 90 tonnes and a maximum lifting height of 66 metres and is suitable for off-road use.

Company owner Geri Clausen commented, “The LTM 1150-5.3 is a powerful all-rounder allowing flexible use thanks to its variable driving conditions. Its five axles make it very compact and manoeuvrable. With the detachable boom, it also offers a great advantage for a variety of operations in our mountainous region.”

Cornelia Clausen-Ogi, company owner, added, “The LRT 1090-2.1 rough terrain crane is an ideal addition to our crane fleet, enabling us to offer our customers customised solutions for their projects.” 

Clausen Kran AG was founded in 1972. Its fleet comprises seven Liebherr mobile and crawler cranes with lifting capacities of up to 250 tonnes as well as three heavy-duty tractors.
