12. Load testing the tail lift
Dynamic load testing
Test with nominal load
Place a test load on the platform according to the
table for the respective tail lift model and lifting
capacity. Check that the tail lift operates correct in
the normal range of movement allowed ie. up, down,
tilting at the ground level and tilting at the vehicle
floor level.
Test with over load.
Place a test load on the platform according to the
table for the respective tail lift model and lifting
capacity. The test load should be 1,25 x the lift
models max load. Check that the tail lift cannot lift
this load (it may, however, be possible to operate
the tilting movement). Remove the test load from the
platform.
Test of safety functions
The tail lifts safety functions must be tested
Check:
- That the red lamp in the vehicle cabin turns off
when the platform is completely closed against
the body and that it turns on when the platform is
opened (where applicable).
- That the tail lift will not operate if the cabin switch is
in the off position.
- That the tail lift cannot be operated when the main
current fuse is removed (where applicable).
- That the overflow valve is activated when the lift is
run up to the floor level or armstops.
- That the tail lift cannot be lowered or tilted down
respectively if the electrical connector from the lift
and tilt cylinders respectively electric safety valve is
removed.
-That the platforms max load marking has been
included and is correctly positioned according to the
loading diagram for the tail lift model concerned.
- That the warning flags are installed and fulfill their
function correctly.
- That all safety and operating stickers are installed
in their specified position.
- That the platform´s mechanical lock functions
correctly (where applicable).
- That the Operator´s Handbook has been left in the
driver´s cabin.
- That the declaration of CE conformity has been
filled in (where applicable).
