Engine speed / drive level:

full power at low revs

On a Tier 4i /stage IIIB generation loader,

the engine speed should be between

1,300 and 1,500 rpm and for machines

of the Tier 3 /stage IIIA wheel loader

between 1,400 and 1,600 rpm. The

hydrostatic drive achieves its full pump

performance at 60 to 70 % of the engine

speed, depending on the type of use.

Full power and low revs enable drivers

to work efficiently and save fuel.

Shovel position: fill the shovel

in a cutting, flowing process

The driver can achieve maximum results

by taking the material onto the shovel in

a cutting process. Note the control

angle and the alignment of the shovel

attachment. These show you the shovel

position in the material from the parallelity

of the blade. If you practice the right shovel

guidance, the cutting process takes care

of itself during forward movement and lift.

Fill the shovel in a flowing movement

without interruption. Filling a shovel

without touching the material with the front

tyres will also reduce tyre wear. Fast and

precise work are also supported by the

automatic shovel return, which makes it

easier to return the shovel to the parallel

rest position.

Only use manual tractive

power control when needed

When working on very loose ground such

as sand, you should set the machine’s

tractive power to manual. Manually

reduced tractive power will enable you to

move and work with the highest traction

possible. When you are working in sand,

for example, this will prevent the tyres from

spinning. Manual tractive power control is

available on all medium and larger series

Liebherr wheel loaders. For standard

operations you do not need manual

tractive power control. Conventional

wheel loader operations require pressure

peaks on the drivetrain in certain situations.

If in this case you reduce traction manually,

there will not be enough power on the

travel drive. Trying to increase this with the

throttle will unnecessarily use more fuel.

Use the inch pedal as necessary

to freely control traction

If necessary, you can freely control traction

with the inch pedal. This may be necessary

for deliberately slow forward traction with

simultaneously high working hydraulic

performance, for example, when loading

a truck. As a rule, it is not necessary to

brake manually as the hydrostatic travel

drive already features a self-actuating

braking effect.

Wheel loader operating tips

Engine speed range, drive stage and shovel control are the essential parameters that drivers can use to

influence the economy of their wheel loader. The following tips will help you to get the most out of your

machine, achieve good turnover rates and, at the same time, save fuel.

Advice – Part 2

Engine revolutions

at a glance.

With full power at low engine speed,

drivers work efficiently and save fuel.

The inch pedal should be used for

deliberately slow forward traction

with simultaneously high working

hydraulic performance.
