Tipping load
Tipping load is the load at which the rear tires lose contact
with the ground (tipping forward). Tipping load is inuenced
by several factors:
• The total load on the loader boom (attachment weight
and load combined)
• The distance of the load from the front tires
• Straight or articulated position of the loader frame
• Levelness of the ground
• Installed counterweights
• Driver presence
• Movements of the loader and the load
Overload will cause the loader to tip
forward. Always pay attention to safe
operating conditions whenever lifting
loads or handling heavy attachments.
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 tted 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 750 mm
in front of the front axle (400 mm from the pallet forks at
ground level), the tipping load is about 470 kg with a driver
weighting 75 kg and with the articulated frame turned to
max articulation.
If you leave the loader, 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 standard pallet fork attachment
(90 kg) is taken into account.
Load diagram
You can evaluate the load handling capability of the
loader with the load diagram, shown below, and the Rated
operating capacity shown on the next page and on the
label on the loader.The load handling capability depends
on 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), dened as 60 % of
tipping load for pallet forks.
Avoid overloading the loader -
know the load and lifting capacity
of the loader. The diagram is valid
only on rm and level ground, with the
conditions listed above.
