B5 Rear carriage
Step 2
1. Extend the rear main cylinder (4)
approx. 50 mm.
→ The rear cylinder head (27) is
pressed upwards and pulls the roll-
er blocks (36) against the rail (8).
→ The rear carriage tube (25) is
pressed downwards with the rear
carriage rocker (26) against the lift-
ing force.
→ Cantilever frame moves upwards
accordingly.
→ The rear carriage is in a load-trans-
fer state.
→ Clearance is created on the domed
nuts (62).
2 Screw down the auxiliary tie nuts
(61) until they rest against the main
frame chord (23).
→ The rear carriage rocker is secured
in the bottom position.
(Fig. B5.02)
Force progression in a load-transfer
state
The lifting force from the main frame
chord is transferred to the rail (8) via
auxiliary tie rods (51) and roller blocks
(36).
The hold-down brackets (28) carry the
force to the anchor tie rods (52) which
then transfer the force into the
structure.
