Liebherr’s new HS 8200 duty cycle crawler crane is based on its predecessor, the HS 895 HD, but the machine boasts an even better performance capacity.
The HS 8200 is the new Liebherr duty cycle crawler crane in the 200-tonne category.
The new duty cycle crawler crane’s design combines safety, performance and economy, as well as a high level of operator comfort, according to the manufacturer.
Thanks to the newly designed drive system, the performance and load capacity is increased by 15 per cent.
The crawler crane is an ideal machine for extraction work and is capable of not only using a dragline bucket but also a grab.
Like all products in the series, the Liebherr HS 8200 may be used for various applications. For deep foundation purposes, the machine can be applied for dynamic soil compaction, as well as fitted with a casing oscillator or fixed leader.
When digging a shaft, the winches can even be used with the full 35-tonne line pull in the fourth layer. Thanks to various counterweight options, the duty cycle crawler crane also performs well in lifting operations.

The new design allows the maximum transport weight of the HS 8200 to be reduced to only 48 tonnes. In comparison to the previous model, that equals a reduction of 12 tonnes.
The rails and walkways on the uppercarriage of the crawler crane, which enable safe access to all service and maintenance points at all times, do not have to be dismounted during transportation. This allows quick transfers between jobsites, creating an economic advantage.
Ground pressure monitoring
The ground load-bearing capacity and the monitoring of the ground pressure are decisive for the safe operation of a construction machine.
The ground pressure visualization of the HS 8200 crawler crane calculates the current ground pressure of the machine in real time, and compares it with the specified safety limits of the relevant jobsite.
The ground pressure is displayed in the operator’s cab and the operator is permanently aware of whether the machine is situated in, or is approaching, a critical area. Dangerous work manoeuvres may also be avoided or adapted in good time.
Revamped crawler crane design
The whole concept is completed by a revamped design, which the machine operator experiences in the new cabin. Principle focus was set on operator comfort. For example, the oil levels of the swing drives, as well as the grab and closing winches can be simply observed on the operator’s monitor.
A modern air-conditioning system with improved airflow, an optimized field of vision and reduced noise emission, as well as an ergonomic operator’s seat with integrated heating and cooling ensure a pleasant operator’s experience.
