** Many factors influence the force found at a loader crane stabiliser support leg:

• If the vehicle is loaded or partially loaded

• The vehicle’s pneumatic tyres

• The vehicle’s suspension system

• The torsion resistance of the vehicle

• How hard the stabiliser jacks are deployed

• Working on sloping ground

The crane must be operated as stated in the use & maintenance manual supplied with the crane.
