26 Training Operators and Instructors of Powered Industrial Lift Trucks (Forklifts)
TRAINING PROGRAMMES
4. Operating safety rules and practices
Operators shall have:
a comprehensive knowledge of the safety standards, rules,
procedures and codes applicable
an appreciation of the capital value of the forklift and equipment,
and its maintenance costs. Similarly, an appreciation of the costs
of damage to plant and equipment
an appreciation of the value and type of product being handled
and, in particular, the precautions to be taken.
Operators shall be able to explain or demonstrate:
the rated capacity of a forklift, the nominal capacity and the
actual capacity at various lift heights and load centres, or with
various attachments, can be much less than the nominal capacity
of the forklift
the factors affecting stability: the principle of a seesaw with its
fulcrum point should be compared with a forklift, and with basic
forklift stability. The principle of the stability triangle, the effect
of mast lift height on stability, the effect of mast forward tilt
on forward stability and rear tilt on sideways stability, should be
clearly illustrated with diagrams or by demonstration. The effects
of inertia, centrifugal forces and ground conditions on the centre
of gravity of the forklift, whether laden or unladen, should also be
understood
the four standard tests as per NZS/ANSI/ITSDF B56.1:2005 name
Table 1 should be shown, along with examples of the rated capacity
of a common-size forklift; illustrating how the capacity reduces
considerably above a certain height. The effects of widening the
wheel base and stability triangle by fitting dual wheels. The effects
of attachments on load capacity
it is recommended best practice that under no circumstances
should more than one forklift be used to lift one load
where an unusual load is being handled, which may require more
than one forklift to be used, an additional person shall supervise
and be responsible for control of the operation; and a written risk
assessment shall be recorded. Consideration should also be given
to using alternative lifting equipment
how the floor and ground conditions, e.g. wet surfaces, curbs,
gullies, cambers and ramps, can affect the stability of a forklift.
This should further explain the reduction in sideways stability with
a raised load.
the correct procedure on ramps, given the operating conditions,
and where possible, keeping the load facing up the ramp whether
ascending or descending. When driving a powered industrial lift
truck in the empty (no load) condition, the forks should point
