Section 1: Operating Instructions & Conditions
1.1: Understand the Capacity of your Lift-Truck
The basic function of a lift truck is to lift, move and place materials. It operates
on the seesaw principle - two weights on opposite sides of a fulcrum. In this
case, the load on the forks must be balanced by the weight of the Combilift.
The location of the centre of gravity of both the Combilift and the load is a
major factor.
1.2: Centre of Gravity (CG)
The centre of gravity of any object is the single point
about which the object is balanced in all directions. Every
object has a centre of gravity. When the lift truck picks up
a load, the truck and load have a new, combined centre
of gravity.
The Combilift has moving parts that change its centre of gravity. The centre of
gravity moves forward and back as the mast is extended and retracted and
also as the mast is tilted backwards and forwards. The centre of gravity also
moves up and down as the mast moves up and down.
