C2 Pushing the rail forward

General

Danger
The rear carriage as well as the rail are
subjected to high lifting forces.
If connecting elements are improperly
released, this can lead to sudden lifting
of the rear carriage or rail and cause the
balanced cantilever equipment to crash.
⇒ Only open the connecting elements
if the person in charge has given the
go-ahead.
⇒ Attach markings for the required
screw-in depth on all tie rods which
are connected by means of hexago-
nal couplers, and take this into con-
sideration when fastening.
Warning
Incorrect operation or hydraulic damage
can cause unforeseen machine
movements.
As a result, body parts could become
trapped and crushed.
⇒ Keep your distance from the ma-
chine while operating the hydraulic
cylinder.
⇒ Do not change the switch status of
the hydraulic system while working
on the machine.
⇒ Do not place hands between clamp-
ing points.
Requirements
■
The pre-cast bridge section must
have sufficient load-bearing capacity.
■
Remove all loose components from
the rail.
■
Remove mounting parts from the rail
if these have to pass under the
carriages.

Preparations

1. On the rear carriage, release the
hold-down brackets (28) of the rail.
To do this, loosen the bottom domed
nuts (62a) on the bottom anchor tie
rod (52a) and turn the hold-down
bracket to the side.
2. Extend the rear main cylinder
approx. 50 mm.
→ The rear cylinder head pulls the
roller blocks (36) upwards, thereby
raising the rail (8).
(Fig. C2.01)
The rear carriage must still be held in
place by the anchor tie rods (52b).
Do not release the top domed nut (62b)
and hexagonal coupler (64)!
