12.2 Dynamic load test.
12.2.1 Test with max. load
Place a test load on the platform, as shown in table (for each lift model/lift capacity). Check that the lift oper
-
ates correctly in the normal range of movement, i.e. up, down, tilting at ground level and tilting at vehicle floor
level.
12.2.2
Test with overload
Place a test load on the platform, as shown in table (for each lift model/lift capacity). The test load should be
1.25 x the lift model’s max. load. Verify that the tail lift cannot lift the load when the up function is switched
on (it may however be possible to tilt up the load).
Dynamic load (Test load 1.0 x tail lift loading capacity). For tail lifts with load centre of 750 mm

Test of safety functions
The tail lift functions must be tested.
Check:
• That the red light in the driver's cab is disabled when the platform is in transport position and vice a versa,
and that it is enabled when the platform is deployed.
• That the tail lift cannot be activated if the cabin switch is in the off position.
• That the tail lift cannot be activated when the main switch fuse is removed.
•
That the overflow valve is activated when the lift is operated up to the vehicle floor level or end stops.
• That the tail lift cannot be lowered or tilted down if the electrical connector from the electric hose rupture
valves is disconnected from the lift and tilting cylinders respectively.
• That the platform
max load sticker is present and suitably positioned in relation to the load diagram for the
lift model concerned.
•
That warning flags and reflectors are fitted and fulfil their function correctly.
•
That all safety and operating stickers are affixed in their respective positions.
• That the platform's
mechanical locking device is working (if accessible).
• That the instructions for using the tail lift have been left in the driver’s cab.
•
That the CE declaration of conformity has been completed.
