3.9 Tipper/tipper bodies- The rear pivot bearings of the three-sided and rear tip bodies must be located close to the rear axle.
- Make provision for guide brackets for the pivot bearings, so the tipper is guided when lowered.
- The maximum pivot angles and tipper lengths, in consideration of max. body exterior dimensions, are derived from the axle load calculation.
- The ram carrier must be attached to the cross member in the subframe assembly.
- The subframe cross members should be located above the cross members of the vehicle chassis frame.
- On three-sided tipper bodies, the working point of the tipper ram should be placed where possible in front of the centre point of gravity of body and payload.
- Safety
If necessary, prevent the tipper from creeping down. Prevent unauthorised operation. A control lamp must be connected in the cab as an optical warning (tipper not in driving position).
- Subframe
The subframe must be manufactured with sufficiently dimensioned steel cross members throughout the structure. Finish rear area to box body and reinforce with diagonal cross. Join subframe relative to load to vehicle chassis frame as per item 3.3.3.
- To fix the sides of the subframe, weld guide plates in the area of the cross members on the subframe.
- Subframe resistance moment figures:
Model | Wx/longitudinal member in cm3 | | Crafter 30 (3,0t)
Crafter 35 (3,5t) | 30 | For profile dimensions see diagram item 3.3. The figures given refer to normal operating conditions, without overhang extension. | Crafter 50 (5,0t) | 40 |
