New Liebherr HD crawler

28 February 2008

Liebherr unveiled its new 40 tonne capacity heavy duty crawler crane at September's Matexpo 2007 exhibition in Belgium.

The HS 825 HD Litronic is the most powerful model in the 40 tonne market sector, according to Liebherr, and completes the manufacturer's 5 Series of hydraulic duty cycle crawlers at the bottom end of the range.

With a maximum self-erecting lattice boom length of 47 m, the compact HS 825 HD embodies a “universal machine concept” which the company said was unique to its class, allowing it to work on the most demanding range of applications.

“This universality distinguishes the new HS 825 HD Litronic definitively from other machines in the 40 tonne class, which for the most part are designed for pure lifting work,” said Liebherr's Wolfgang Pfister.

Possible applications include work using a dragline bucket, clamshell, diaphragm-wall grab or casing oscillator, along with straightforward lifting tasks. The model has standard telescopic undercarriage and crawler pads 700 mm in length, with a transport width of 3 m. The 37 tonne transport weight without counterweight also means the machine can be relocated economically, explained Phister.

It is fitted with a six cylinder 180 kW/245 hp new generation Liebherr diesel engine, compliant with Stage 3/Tierr III noise and exhaust emission regulations. A more powerful 270 kW/376 hp version is also available.

Standard equipment includes 16 tonne free-fall winches with maintenance free multi-disc brakes and Liebherr's Litronic system, which comprises all control and monitoring functions and is designed to withstand extreme temperatures and heavy duty tasks.
