FOPS canopy
FOPS canopy (Falling objects protective structure)
mounts on the ROPS. It meets the ISO 3449:2005
FOPS level 1 (1365 J) criteria.
Rated operating capacity
To determine how much the loader can handle safely, a
table of the tipping load and a calculated Rated Operating
Capacity (ROC) is shown in the adjacent label.
A rated Operating capacity label is located near the driver’s
seat and can be read while you sit on the driver’s seat
Rated operating capacity depends on type of use of the
loader:
• In bucket and general application the rated operating
capacity is 50% of tipping load
• In pallet fork application the rated operating capacity is
60% of tipping load
The information shown in the table is the worst case
minimum load, with the conditions listed below. Actual lifting
capacity could be significantly higher, or it may be lower,
depending on terrain conditions, available lifting force, and
load distribution. Adding or removing counterweights will
affect the indicated ROC.
The ROC table is valid, when:
• The ground is firm and level
• Loader is stationary or driven max 2 km/h, with smooth
and slow control movements
• Driver 75 kg is seated on the driver’s seat
• Load is distributed evenly on pallet forks, with the load
centre of gravity at 400 mm from the vertical part of
pallet fork arms. The weight of the fork attachment is
taken into account in the indicated load values
Risk of tipping over when
handling heavy loads - See the
warnings and safety instructions
about handling of heavy loads
shown in this manual.
Tipping load
Tipping load is the load at which the rear tires 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 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
conditions operating whenever loads or
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 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 750 mm
in in front of the front axle (400 mm from the pallet forks
at ground level), the tipping load is about 1250 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), defined as 60 % of
tipping load for pallet forks.
