Liebherr has launched a trio of new mid-range wheel loaders – the L 526, L 538 and L 546 – featuring optimised travel drive performance, modified lift arms, a redesigned operator’s cab and an exhaust gas treatment system that means all three models comply with the emission Stage V/Tier 4f guidelines.
The improved hydrostatic travel drive on all three machines has given the L 538 and L 546 models significantly more engine power whilst fuel consumption remains low, reducing both fuel costs and CO2 emissions.
With the new mid-range wheel loaders, two lift-arm variants are still available before purchase, including z-bar kinematics with high forces in the lower lift-arm positions and newly reinforced bucket arms for increased robustness.
Standard versions of the mid-range L 526, L 538 and L546 weigh in at 11.77, 15.5 and 14.2 t respectively, whilst bucket capacities are 2.1, 2.6 and 2.8 m3. Articulated tipping loads are 8.0, 9.5 and 10.5 t, and engine power outputs are 100, 120 and 138 kW respectively.
The electro-hydraulic pilot control in combination with the standard bucket programming function means that bucket positions can be set on the 9 in. touch display in all models, whilst the powerful hydraulics ensure that the machine operator can also carry out overlapping movements of lifting and lowering as well as tilting in and out at full power, resulting in more efficient operation and increased productivity.
Moreover, new optional stroke limit damping helps protect the wheel loaders and also reduces vibrations for the machine operator. This function allows for smooth moving to the end position of the working attachment and of the lift arms, increasing the life of all components.
As with the XPower large wheel leaders, joystick steering is available for the mid-range wheel loaders upon request. This system can be operated intuitively as the position of the joystick always corresponds to the articulation angle of the wheel loader.
To optimise safety and comfort in day-to-day work, Liebherr are also offering all assistance systems from the XPower large wheel loaders with the new mid-range wheel loader series, including, for example, active personnel detection at the rear, on-board weighing with Truck Payload Assist, integrated tyre pressure monitoring and adaptive working lighting. Front-space monitoring and the Skyview 360° camera system are also available.
