Liebherr launches three mid-range wheel loaders

Share

The new Liebherr L 526, L 538 and L 546 mid-range wheel loaders come with a marked increase in the performance of the travel drive, modifications to the lift arms and a redesigned operator's cab.Exhaust gas treatment makess all the three models comply with the emission stage V/tier 4f guidelines. For the first time, the assistance systems and new joystick steering from the XPower large wheel loaders are available for the mid-range wheel loader series.

During development, Liebherr engineers optimised the proven hydrostatic travel drive on all three models. This has given the L 538 and L 546 models significantly more engine power and the L 546 now comes with an new, powerful, six-cylinder engine. The hydrostatic travel drive means consumption remains low. This reduces both fuel costs and CO2 emissions.

Two lift arm variants are still available before purchase. One option is the z-bar kinematics with high forces in the lower lift arm positions. The alternative is the parallel kinematics with enormous holding forces in the upper areas as well as parallel guidance. It is suitable for industrial applications with heavy equipment such as handling metal scrap or glass.

Liebherr has redesigned both lift arm variants for the new series. The L 538 and L 546 models for example have been given larger lift cylinders, which has increased the lifting 1 / 4force by 20 percent compared to the previous generation. The newly reinforced bucket arms with z-bar kinematics increase robustness.

The electro-hydraulic pilot control in combination with the standard bucket programming function enables the bucket and forklift positions to be set on the large 9-inch display in all models. 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. The result is more efficient operation and productivity increases.

The new optional stroke limit damping allows operators to protect their wheel loaders and also reduces vibrations for the machine operator. This function enables smooth moving to the end position of the working attachment and of the lift arms. This increases the lifetime of all components, especially those of the lift arms and the installed attachments.

Liebherr is also offering all assistance systems from the XPower large wheel loaders in the new mid-range wheel loader series. This includes, for example, the active personnel detection at the rear, the weighing device with Truck Payload Assist, the integrated tyre pressure monitoring system and the adaptive working lighting. The front space monitoring and the Skyview 360° camera system are also available.
