New Z-unit bar linkage: full output with greater versatility
The new Z-unit bar linkage on the L 514 and L 518 models provides maximum force in all operations. It delivers high breakout forces in the lower lift arm range, which is an advantage in earthmoving, and also excels with enormous holding forces in the upper range. The latter is important when working with heavy equipment, such as a high-tipping bucket or a bucket with a hydraulic clamp. The new Z-unit bar linkage enables the machine operator to work precisely and safely with a loading fork over the entire lifting range. This characteristic is of key, particularly in municipal services or ancillary activities in construction and civil engineering.
With the Z-unit bar linkage, operating companies can use all machine attachments productively. The L 514 and L 518 Stereoloaders® can work at full output with a road sweeper, for example, or with a snow plough for winter operations. To accompany the new linkage, Liebherr is offering a new hydraulic quick hitch for both Stereoloader® models. This improves versatility because it enables operators to switch tool attachments more efficiently. The sophisticated design provides a clear view of the working area and equipment including the fork tines, for example. Safety is increased for both the operator and the load.
Powerful components, well-engineered cooling system: focus on reliability
Liebherr Stereoloaders® can undertake a wide range of tasks reliably. To make this possible, Liebherr has invested in the robustness of various aspects of the new L 514 and L 518 models. Take the axles for example: their automatic self-locking differentials provide outstanding traction even on difficult terrain. The robust basic design, high quality steel components and tried and tested hydraulics guarantee reliability regardless of what operation the Stereoloader® is performing.
The newly-developed cooling system in the L 514 and L 518 Stereoloaders® guarantees high levels of productivity. It directs the cooling air diagonally through the entire engine compartment, ensuring optimal heat dissipation from the engine. The system delivers just the right amount of cooling capacity on demand, thereby reducing fuel consumption and noise emissions. The location of the cooling system, directly behind the operator’s cab in the cleanest position on the wheel loader, has several advantages. In that position the system can suck in clean air, which improves the system’s durability and reduces maintenance costs. And personnel can easily and safely reach the cooling system from the ground for cleaning and maintenance.
Innovative design: a focus on comfort and safety
With wheel loaders of this size, there are typically different machine operators working on the construction site. Therefore, Liebherr has developed the L 514 and L 518 Stereoloaders® to be operated intuitively. Clearly organised ergonomic controls offer movement tracking and Liebherr operating levers are integrated into the driver's seat to ensure easy handling, which saves time and increases flexibility on site.
A wide access ladder with non-slip treads and large handrails leads to a spacious and comfortable cab. Comfort is enhanced by a cab door that opens through 180° and a steering wheel, display and driving seat that can be individually adjusted. Thanks to its large windows, the redesigned cab offers outstanding visibility on all sides. The machine operator has a complete view of everything in the immediate vicinity. Powerful headlights provide vision in the dark and can be individually customised by the customer on request.
At Liebherr, safety is a top priority. This is reflected in the design of the L 514 and L 518 Stereoloaders®. The compact engine hood has clear lines that make it easier for the operator to oversee the machine. In addition, the engine compartment is protected from dirt thanks to a completely closed top. Once the engine hood has been opened, the engine compartment can be safely accessed from the ground for maintenance and servicing. The engine is transversely installed at the rear of the wheel loader and therefore serves as a natural ballast weight, as do the hydraulic pumps. This design produces optimal weight distribution, which results in higher tipping loads and more agile handling.
