Many manufacturers place great emphasis on the registered operating weight for their wheel loader products, suggesting that the heavier the equipment, the greater its lifting capacity. Although one could argue that increasing the overall weight of the equipment could result in greater lifting ability, the only thing for certain is that fuel economy will be sacrificed, says Liebherr.
Liebherr emphasizes the consideration of a wheel loader’s tipping load as a much more critical factor. In fact, it is the tipping load that determines the proper bucket size, and by extension, the payload capacity for a given wheel loader. Further, the tipping load factor for a wheel loader can be increased by means other than simply increasing the overall operating weight of the equipment.
The Liebherr wheel loader offers equal to or better than, tipping load ratings, while maintaining significantly lower operating weights, resulting in increased productivity and reduced fuel consumption.
This is a direct result of the utilization of a hydrostatic driveline, and the advanced design of our wheel loader product, which places the Liebherr diesel engine and hydraulic pumps, the heaviest components, to the extreme rear of the machine where they act as natural ballast. As a result, the centre of gravity for a Liebherr wheel loader is located to the rear of the back tires, as opposed to torque converter designs whereby the centre of gravity will be much further forward due to the necessary configuration of a “hard line” drive system.
Better weight distribution, hydrostatic drive, reduced brake wear, reduced tire wear and reduced weight all add to reduced operating costs for Liebherr wheel loaders.
The Torque Parallel linkage on these loaders give smooth, parallel lift, high rollback torque and excellent lifting power throughout the lift range. A key element to any wheel loader is visibility, and the linkage on both machines provides class-leading pallet visibility, along with a clear view of
Both models are equipped with separate power steering and load-sensing hydraulic pumps, while differential locks offer 100 per cent lock in both the front and rear axles to ensure synchronized tire spin for optimal traction even in difficult conditions.
Operator comfort has been recognized with the Volvo Care Cab on the L45F and L50F machines delivering all-day operator comfort. Standard air conditioning includes automatic temperature control to suit the operator’s demands, while each cab is installed on fully viscous mounts for reduced noise and vibration and features best-in-class cab filtration system. Cab interiors are designed for fatigue-resisting ergonomic comfort, ensuring that the steering wheel, steering column, standard air suspension seat, armrest and levers can all be adjusted to match each operator. Controls and front-pillar mounted switches are all within easy reach and easy view.
Both loaders are powered by Tier three certified water-cooled turbo-charged Volvo D5 4.8 litre engines. The Volvo L50F engine also includes an air-to-air intercooler with both engines achieving high torque at low engine speeds.
Fully hydrostatic transmissions allow smooth shifting and direction change under full load, prolonging the life of the brakes. A thermostatically controlled, 3-mode reversible hydraulic fan is available, automatically adjusting to reverse air flow and blow any material or debris out of the radiator.
Both L45F and Volvo L50F models are based on a heavy duty articulating frame concept. The front and rear frames are designed for maximum ground clearance, while high-quality steel throughout provides durability, increased stress resistance and operational stability. In addition, both machines are offered with optional Z-bar Volvo patented model attachment brackets. Rear axle oscillation increases machine stability, while low-maintenance features – like a heavy duty planetary axle and sealed, integrated oscillating bearings lubricated with the axle oil – increase machine uptime. Inboard wet-disc brakes improve reliability and safety.
