LIEBHERR has introduced the L 509 Tele, a telescopic wheel loader which combines the lift height and reach of a regular telescopic loader with the material handling capacity of a ‘classic’ wheel loader.
The machine can reach a top speed of 38 km/h and complies with the emission Stage V/Tier 4f specifications.
The L 509 Tele features an extendable telescopic lift arm, which can lift to a height of 4.8m with a fork attachment. Liebherr explained that thanks to integrated z-bar kinematics, the lift arm allows operators to load containers and lorries at great heights or stack loading material.
A newly designed hydraulic quick coupler enables switching between work tools. The compact design is said to ensure a good view of the attachment being used. The connection dimensions are the same as the L 506 Compact – L 509 Stereo wheel loaders.
The cab contains a height-adjustable 9-inch touch display. Liebherr has modified some aspects of the standard stereoloader cab, for example it has a sunroof window to allow operators to clearly see the works tools and material being handled, even when the telescopic lift arm is extended.
The mini-joystick on the control lever is used for retracting and extending the lift arm as well as controlling hydraulic work tools. The ‘Comfort operation Tele’ is available on request and includes automatic bucket return-to-dig, programmable auto lifting and auto lowering as well as visualisation of the equipment position on the display.
Liebherr has equipped the L 509 Tele with an overload warning system as standard. This consists of a load torque limit and a load torque indicator on the display to inform the operator about the bearing load situation and stability of the loader.
The model also has a reduced articulation angle of 30 degrees thanks to stereo steering. As a result, Liebherr added that the centre of gravity remains in the centre of the machine when transporting large loads, which increases stability.
