18 Obtaining the Best Accuracy
Lifting Speed
The hydraulic pressure required to lift a load varies with the speed of lift.
The LR810 electronically corrects for most variations, but better accuracy is
obtained if you limit the range of lifting speed used.
Keep engine revs consistant
Trigger Point
The hydraulic pressure required to start lifting is much greater than is
required to keep the load moving smoothly upwards. It is important that the
load is moving at a steady speed when it reaches the trigger point.
We recommend that you:
Start the lift well below the trigger point
(In terms of time, at least 2 seconds of lift before the trigger point.)
Bounce
Most loaders have pneumatic tyres which can cause the machine to bounce
when lifting. Any bounce causes variation in the hydraulic pressure and
affects the accuracy of the weight measurement.
To minimise the effect of bounce:
Always operate the lift lever before accelerating the engine and as
recommended above “Start the lift well below the trigger point”
Centre of Gravity
The hydraulic pressure in the lifting cylinders depends on where the centre
of gravity of the load is.
It is important that:
The bucket is always in the same position - fully rolled back
Uneven Ground
Uneven or sloping ground changes the pressure required to lift a load and
hence affects the accuracy of weighing.
Whenever possible:
Avoid weighing on uneven or sloping ground.
