With its new HS 8300 HD duty cycle crawler crane Liebherr presents an innovative machine concept at the Bauma 2013 combining the traditional "heavy duty" design with state-of-the-art technologies. Thus, the efficiency of the duty cycle crawler crane weighing over 350 tonnes is significantly improved during practical application.

For a further increase in performance a powerful and eco-friendly hybrid drive was developed and the crawler crane is fitted with hydraulic free-fall winches offering approx. 50 tonnes of line pull.

When developing the new duty cycle crawler crane Liebherr paid special attention to an extended service life of its product. Therefore, the steel fabrication of the basic machine is extremely solid and critical points were reinforced using extra high-quality materials such as carbon fibre. Furthermore, special production methods including the use of automated welding robots increase the machine's service life even under extreme operational conditions.

At the Bauma 2013 the HS 8300 HD is displayed with a hydraulic orange-peel grab made by Negrini. Moreover, the duty cycle crawler crane is suitable for various applications including dragline and grab operation or other material handling jobs.

Powerful and energy-saving hybrid drive

The new HS 8300 HD is fitted with the new Pactronic® system developed by Liebherr. This innovative hybrid drive based on hydraulics offers both economical and ecological advantages. Surplus energy is stored and subsequently regenerated so increasing the material handling capacity while at the same time significantly reducing fuel consumption. Moreover, the proven technology of the hydraulic accumulator ensures low maintenance requirements and maximum reliability. The reduced energy consumption considerably reduces emissions therefore causing much less environmental pollution.

As other Liebherr machines the HS 8300 HD also incorporates many components and system solutions developed by Liebherr. Apart from the homogeneous system environment this also guarantees high availability of spare parts within the Liebherr service network.

The proven Litronic control system which is based on CANBUS technology and includes all control and monitoring functions of the machine belongs to the standard equipment of the HS 8300 HD. The Litronic system works reliably even under extreme weather conditions and vibration.
