Wheel loader for cost-effective Block Handling

Marble has not only been used in art and sculpture for centuries, but has also been very popular for architecture and for both the interior and exterior design of buildings throughout the ages.

To ensure that the rock can be ﬁ nished to the best possible effect it is extracted in the largest possible block sizes. A wheel loader is then responsible for removing the solid, valuable marble blocks. The block handling version of the Liebherr L 586 2plus2 wheel loader has been specially developed for this purpose.

The hydrostatic drive used in the block handling machines from Liebherr provides the high level of economy and safety to which Liebherr users have become accustomed. It reduces fuel consumption by up to 25% and features excellent weight distribution as a result of the unit installation position of the components. In addition the foot brake suffers practically zero wear. When driving on gradients, the hydrostatic braking effect massively enhances the safety of the driver and the area around the machine.

Like all Liebherr wheel loaders, the block handling machines are also operated using a single control lever. The driver’s left hand can remain on the steering wheel at all times, resulting in greater comfort and safety for him.

Liebherr has a range of optional equipment which has been designed specially for block handling and using which the wheel loader can be tailored perfectly to the speciﬁ c conditions in which it is used. The quick-change device included in the block handling package provides a high level of ﬂ exibility.

Maximum performance, economy and reliability as well as comfort in the equipment used in the machines make Liebherr an ideal partner for block handling.

Economy

Compared to conventional transmission, the Liebherr driveline achieves a reduction in fuel consumption for wheel loaders of 25% or more! 5 litres less fuel per operating hour signiﬁ cantly reduce operating costs and environmental pollution.

Reliability

All the materials used in Liebherr wheel loaders have passed long-term tests to ensure that they match up to Liebherr’s exacting standards even in the toughest conditions. The mature concept and proven quality make Liebherr wheel loaders to the benchmark for reliability.

Performance

The Liebherr driveline allows the Liebherr diesel engine to be mounted lengthways in the rear, with the output shaft facing backwards. Compared to conventionally driven wheel loaders, the operating weight is much lower, the tipping load is higher, and more material can be moved each operating hour.

Comfort

The ultra-modern cab design with advanced ergonomics, continuously variable Liebherr driveline with 2plus2 gearbox for uninterrupted tractive force, standard Liebherr ride control, optimum weight distribution and easy service access thanks to unique engine installation position lead to extraordinary overall comfort.
