Testing and verification
Testing and verification of the tail lift is performed in accordance with installation/delivery inspection. Verify
that the tail lift is suitable for the vehicle in question and for the intended use.
12.1 Static test loading
12.1.1 Deformation
Position the tail lift halfway up to vehicle floor level and with the platform in the horizontal position. Measure
dimensions A-B-C-D for comparison, as illustrated.
Place a test load on the platform according to the table (for relevant tail lift model and lifting capacity).
Remove the test load from the platform.
Repeat the measurement of A-B-C-D and verify that there has been no permanent deformation of the lift or
its mounting.
12.1.2 Drift
Place a test load on the platform according to the table. The tail lift must be at the same level and angle as
the vehicle floor. Leave the test load for 15 minutes.
Verify that the platform drift is no more than 15 mm in the vertical direction (points A and D) and not more
than 2° in terms of the angle (points B and C) in relation to vehicle floor level.
12.1.3 Static load (test load 1.25 x tail lift loading capacity). For lifts with a load
centre of 600 mm
