Vehicle chassis requirements
In order to comply with the applicable underrun
protection standards, there are requirements for the
vehicle chassis on which the rear tail lift is mounted.
The moment of inertia in a cross-section of the
frame beam concerned (excluding any support
frame) must not be less than 1003 cm
4
. Accordingly,
the frame beam’s cross-section must at a minimum
have dimensions as illustrated, corresponding to a
minimum surface moment of inertia of 1003 cm
4
around the x-axis. See
Picture 7.
If in doubt, contact ZEPRO for support.

Statutory dimensions
Make sure the installation location allows the tail lift to meet the statutory dimensions for underrun protec-
tion when in transport mode
Distance between the platform and the ground when the vehicle is unladen:
Max 450 mm for vehicles with air suspension.
Max 500 mm for vehicles with conventional suspension.
If the departure angle with the above setting is less than 8°, the distance between the platform and the
ground on an unladen vehicle must be increased until the angle reaches 8°, but by not more than 550 mm.
Horizontal distance from the outermost part of the vehicle to the platform: Max 300 mm.
See
Picture 8.

WARNING!
The above dimensions are the minimum permit-
ted for the installation of underrun protection. The
strength requirements for mounting the tail lift
usually require larger dimensions.
