Testing the liftgate
59
6.3 Load tests
WARNING
High loading of components
Incorrect installation or defective components may cause components to fail and
break.
Risk of injury when operating the liftgate.
Perform all the load tests specified here.
6.3.1 Static test
Operate the horizontal platform to the height of the vehicle floor.
Place a test load weighing 125% of the rated capacity on the platform within the
loading distance.
During a test period of 15 minutes, the platform must not lower more than15 mm
and must not tilt down more than 2°.
IMPORTANT:
The permissible loading distance and the rated capacity are engraved
on the
liftgate’s rating plate. The loading diagram on the rating plate shows the
permissible loads when the loading distance is changed.
IMPORTANT:
After the static test, the installer must inspect the liftgate for
deformation.
6.3.2 Dynamic test
Test the lifting, lowering, and tilting functions using the maximum permissible
load.
IMPORTANT:
The pressure limiting valve is adjusted ex-works. A correction is
generally unnecessary. If adjustment is necessary, contact the factory.
The maximum permissible pressure is printed on the liftgate’s rating plate.
After performing the static and dynamic tests, visually inspect the hydraulics
system for tightness.
6.3.3 Testing against lifting an overload
Perform a test to guarantee that a load of more than 125% of the maximum rated
capacity cannot be lifted off the ground.
6.3.4 Testing the safety devices
Operate all the functions to their end positions until all the safety devices
respond.
