3.1 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 on the current
frame beam (excluding any support frame) shall not be
less than 937 cm
4
. Thus the frame beam cross-section
must measure at least 220x70x4 mm, which corre-
sponds to a minimum moment of inertia of 937cm
4
around the x-axis. See Figure 7. If in doubt, contact
ZEPRO for support.
3.2 Statutory dimensions
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 300 mm.
See Figure 8.
NOTE!!
The underrun protection must be located further back and lower.
Figure 8. Statutory dimensions
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.
