Tipping load
Tipping load is the load at which the rear tyres lose
contact with the ground (tipping forward). Tipping
load is influenced by several factors:
 The total load on the loader boom
(attachment weight and load combined)
 The distance of the load from the front tyres
 Straight or articulated position of the loader
frame
 Levelness of the ground
 Installed counterweights
 Driver presence
 Movements of the loader and the load
The lifting capacity of the loader is
limited by the possibility of tipping
around the front axle.
The operator must pay attention to
safe operating conditions
whenever handling loads.
Load diagram
With the diagram the load handling capability of the
loader can be evaluated, according to the distance
between the centre of gravity of the load and the
front axle of the loader. The diagram represents the
forward stability only, it does not refer to maximum
available lift force.
The load diagram below shows the tipping loads on a
level surface:
a) Tipping load with the loader frame in straight
position.
b) Tipping load with the loader frame in
maximum articulation.
 ROC (Rate operating capacity), defined as
60 % of tipping load for pallet forks.
The lifting capacity and the stability of the loader are
at the best, when:

the loader frame is kept straight

the centre of gravity of the load is as close to the
loader as possible

counterweights are fitted to the loader

swinging of the load is prevented and all controls
are used in a calm and careful manner
Example: If the centre of gravity of the load is 840
mm in front of the front axle (400 mm from the pallet
forks at ground level), the tipping load is about 390
kg with a driver weighing 75 kg and with the
articulated frame turned to max articulation.
If the driver leaves the machine, tipping
and max. loads are reduced
respectively.
The indicated load is the maximum load
that can be loaded on pallet forks and
the machine will not tip over, i.e. the
weight of the pallet fork attachment (95
kg) is taken into account.
WARNING
Avoid overloading the loader -
know the load and lifting
capacity of the loader. The
diagram is valid only on firm
and level ground, with the
conditions listed above.
