Customized chassis 20 t

The chassis for load capacities of 20 t are welded to size, i.e. no side sections
can be moved or beams removed. Observe the installation procedure described
in the section "Installation of suspended chassis". The same aids and tools are
required. Deviating from this, the following assembly steps must be performed.
Attach the pit jack with a round sling to the front lift rollers. Then lift the pit jack
off the pallet and place it on level ground. Remove the round sling. Attention:
Danger of tipping!
Remove the transport lock and install the compressed air line.
Remove the jack axles including rollers by loosening the four M12 screws on
the jack support plate (see illustration).
Raise the chassis using suitable lifting gear so that it cannot tip over and lower
it over the pit jack until the top plate is approx. 90 mm above the running
surface of the chassis. Then fit the lifting axles including rollers (see
illustration). Tighten the screws to 50 ±5 Nm.
Raise the chassis so that the jack is still firmly positioned on the ground and the
chassis rollers are already in contact with the chassis. Now follow the
procedure for securing the jack described in step (6) in the section "Mounting
the suspended chassis". As the made-to-measure chassis do not have handle
openings, we recommend wrapping the side section. Note the central alignment
