Liebherr wheeled excavators
Wheeled Excavators.The wheeled excavators featuring operating weights of between 9 t and 113 t distinguish themselves via their uniform excavator design, featuring the most state-of-the-art technology. These machines are applied in civil engineering, industrial material handling, tunnelling applications, water resources engineering and demolition and mining industries.
All working attachments including backhoe buckets, bottom-dump buckets, material handling or demolition attachments, are all designed and manufactured by Liebherr themselves.
Performance.Liebherr wheel excavators have been designed for maximum productivity. Maximum digging performances, high lift capacities and quick working cycles are prerequisite for efficient building site operation, and a wide variety of attachments optimize every excavator application.
Comfort.Largely dimensioned and ergonomically designed, the Liebherr excavator cab features an operator’s seat which can be individually adjusted, as well as clearly arranged control instruments and ideal all-round view. Automatic air-conditioning guarantees an optimum temperature in the Liebherr Feel-Good cab at all times.
Economy.The Liebherr-Litronic-System increases machine performance, reduces fuel consumption and minimizes service and maintenance costs. Due to Liebherr’s well-balanced range, the ideal machine can always be selected to suit every application.
Reliability.Liebherr hydraulic excavators have been designed and built to withstand the toughest of conditions at the building site. Their rugged design, high-tensile materials and individual components ensure maximum availability and long life-expectancy.
Innovative solutions
Multitude of attachments.Liebherr provide an individual, application-related range of diverse attachments. Hydraulic booms, adjustable both in height and offset positions, as well as standard and offset-adjustable goosenecks, can be combined with different sticks.
Extensive lifting capacities.Canalization and the lifting of pipes are everyday tasks for rubber-tyre excavators. These requirements are endorsed via an intelligent concept of uppercarriage sectioning together with the positioning of the Liebherr engine, mountedat a transversal angle directly in front of the counterweight. Separate hoist cylinder bearing points at the upper end of the basic boom also increase the lifting capacities considerably.
Quick working cycles.High swing torque – attained as a result of the Liebherr swing ring featuring internal teeth and swing drive, specially designed to increase the torque.
Performance without compromise.Maximum performance and maximum forces are available to the operator at all times.
Liebherr Tool Control.Available as an option, immediately after the changeover of a hydraulic tool, the required pressure and oil flowvalues can be selected with a push of a button. Up to 10 combinations can be programmed. A tool changeover cannot be simpler and more time saving.
Rugged undercarriage.Various undercarriage designs featuring welded, durable outriggers allow safe positioning, optimum stability, and long life-expectancy of the machine for every application. Prop-up blade / dozing blade in box-type design – only two bearing points for high torsional resistance.
