Load test
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 than 3/5” (15 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.
Dynamic test
The functions lifting, lowering, tilt up and tilt down must be tested with a nominal load placed at
nominal load distance. If necessary, the pressure valve must be adjusted so that the load can be
lifted securely.
IMPORTANT
The pressure valve is adjusted in the factory, a correction is generally not necessary.
If it has to be done anyway, please note the following:
The pressure valve can only be adjusted if a manometer for reading the pressure is
provided. The maximum allowed pressure is engraved on the type label.
After the statical and dynamical tests, please check the hydraulic system for leaks.
After performing the static and dynamic tests, visually inspect the hydraulics system for
tightness.
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.
Testing the safety devices
Operate all the functions to their end positions until all the safety devices respond.
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.
