The Gräser-Eschbach Group with companies in Mannheim and Bad Schönborn recently took delivery of a new flagship – its new Liebherr LTM1450-8.1 mobile crane, which will be the largest crane in its fleet. One of its first jobs was to dismantle a tower crane in the new Gateway Gardens business global business village at Frankfurt Airport.
Crane operator Ralf Bundrock had set up the crane with 44 metres luffing jib for the job. The challenge was the constricted space available on the site, which LTM1450-8.1perfectly fits for the job. Managing Director Frank Eschbach highlighted that it was the most economical solution because of its short set-up time and outstanding lifting capacity, particularly with the hook height required. The 85-metre telescopic boom was the main criterion in their decision to purchase the 450-tonne mobile crane.
The main areas of use for the crane will be in structural steel and bridge construction as well as construction crane erection works. In the design of the LTM1450-8.1, Liebherr focused on high economy and simple set-up on site. The 8-axle crane is able to travel on the public road with a 12-tonne axle load including its complete telescopic boom and all 4 outriggers. The LTM 1450-8.1 can work with a variable ballast radius as VarioBallast® enables it to be reduced with infinite adjustment from 7 metres to 5 metres using a simple hydraulic system, a feature which is very practical on constricted sites.
The Gräser-Eschbach Group has more than 70 years of experience as a crane and transport contractor and currently has a workforce of around 100 staff. The company has almost 50 mobile cranes with lifting capacities ranging from 40 to 450 tonnes operating throughout Germany.
