The Liebherr LTR 1060 telescopic crawler crane proves its worth high up in the Alps.
The Swiss company Clausen Kran AG knows all about using cranes in the Alps, having factored in all possible complications. Tellingly, Clausen has placed its trust in Liebherr cranes with their innovative technology and is thus, able to complete all sorts of complicated work in difficult terrain.
The Simplon Pass is one such example. It is in the Pennine Alps and is open to traffic all year round. This is made possible only by several protective galleries, structures to protect traffic routes from avalanches or landslides. Part of one of the galleries on the Simplon Pass, at an altitude of around 2,000 m, is now to be removed and replaced.
Due to lack of space, a crane which can operate on the roof of the gallery had to be used at this site. This crane also had to meet several specifications in terms of weight and size, provide good manoeuvrability and adequate load capacities. Clausen's Liebherr LTR 1060 telescopic crawler crane, an off-road crane with excellent manoeuvrability and a compact one with high load capacities, was ideal for this job.
The first stage was to saw off the concrete of the old gallery into sections. The LTR 1060 had to hold and secure the blocks of concrete during the sawing process. The 60-tonner then loaded the concrete sections weighing between 7 t and 22 t onto waiting trucks. This allowed the telescopic crawler crane to show off its great strength, namely moving with the load on the hook. Around 110 t to 140 t of concrete could be sawn off and removed on a single day. The crane was then moved to a lower level where it removed the supports for the gallery. Clausen Kran AG is a family company which first opened for business in 1972 in Wallis, Switzerland. The company characteristics include many years of experience and a competent, motivated team. Its modern, well- maintained fleet consists of four Liebherr cranes and two heavy transport vehicles. The smallest crane is an LTC 1055-3.1 compact crane whilst the largest is an LTM 1220 5.2.
