3.1
Vehicle chassis requirements
In order to comply with the applicable underrun protec-
tion standards, there are requirements for the vehicle
chassis on which the rear tail lift is mounted.
The moment of inertia in a cross-section on the cur-
rent frame beam (excluding any support frame) shall
not be less than 1929 cm⁴. The cross-section of the
frame beam shall therefore have at least dimensions of
255x70x6 mm, corresponding to a surface moment of
inertia of 1929 cm⁴ around the x-axis. See illustration.
If in doubt, contact ZEPRO for support.
3.2
Statutory dimensions for underrun protection
Distance between the beam and the ground when the vehicle is unloaded:
Max. 450 mm for vehicles with air suspension.
Max. 500 mm for vehicles with conventional suspension.
If the exit angle with the above setting is less than 8º, the distance between beam and ground in an unladen
vehicle may be increased until the angle is 8º, but to Max. 550 mm.
Horizontal distance from the outermost part of the platform to the underrun protection: Max. 294 mm. See
illustration below.
NOTE!
The underrun protection may be placed further back and lower.

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