Testing and verification
11.2
Dynamic test loading.
11.2.1
Test with maximum load
Place a test load on the platform according to the table (for relevant tail lift model and lifting capacity).
Check that the lift operates correctly in the normal range of movement allowed, i.e. up, down,
tilting at ground level and tilting at vehicle floor level.
11.2.2
Test with overload
Place a test load on the platform according to the table (for relevant tail lift model and lifting capacity).
The test load must be 1.25 x the relevant lift model's maximum load. Verify that the tail lift cannot
lift the load when the up function is activated (it may be possible to tilt up the load, however).
11.2.3
Dynamic load (test load 1.0 x tail lift loading capacity). For lifts with a load centre
of 600 mm
Capacity
500 kg

Testing safety functions
The tail lift's safety functions must be tested.
Check:
•
that the red light in the driver's cab is deactivated when the platform is completely closed
against the body and, conversely, that it is activated when the platform is opened.
•
that the lift cannot be activated when the control switch in the cab is turned off.
•
that the lift cannot be activated when the main switch's fuse by the battery is tripped.
•
that the overflow valve is activated when the lift is run up to the vehicle floor level or end
stops.
•
that the lift cannot be lowered or tilted down when dismantling the electrical connection on
the lift cylinders' or tilt cylinders' electrical hose rupture valves.
•
that the platform's "max load" marking is present and correctly positioned according to the
loading diagram for the lift model in question.
•
that warning flags with reflective strips are installed and fulfil their function.
•
that all warning and operating decals are installed in their respective position.
•
that the platform's mechanical locking device is working (where applicable).
•
that instructions for using the tail lift have been left in the cab.
•
that a CE declaration of conformity has been certified.
