Folding the Run-Up Rail Out/In
The run-up rail is folded out for rigging and folded back in for
on-road driving after derigging.
Fold out the run-up rail
• Unscrew the spring latch (2).
• (1) engages in the bore hole (4).
Folding in the run-up rail
• Pull the locking bar (1) downwards against the
spring force, and out of the bore hole (4).
• Fold out the run-up rail (3) to a small extent and let
go of the locking bar (1).
• Fold in the run-up rail completely.
SET-UP AND INSTALLATION
• Secure the run-up rail with the spring latch (2).
Connections With Folded Lattice Extension
The lattice extension is turned sideways to the main boom in
the folded position.
In this position there are four areas on the main boom basic
section, where various connections have to be disconnected
and reconnected again during rigging and unrigging.
- in the front area, in front of the locking point at
100%,
- in the middle area, in front of the locking point at
50%,
- in the rear area, over the side panelling.
In each area there are bearing points that can be used for
establishing connections. Depending on the rigging mode
and job, different parts of the lattice extension must be
connected to each other or connected to the main boom
basic section.
Risk of accidents due to falling parts. Always secure the
pins both in the bearing points and in the holders using
retaining pins. This prevents unsecured pins from
becoming loose, falling out and causing injuries.
Connections in the front area
In the front area there is a connection between the 33 ft (10.1
m) section and the main boom.
This connection must be disconnected when the lattice
extension is being rigged or removed.
The connection is made of retaining pins (3), slewing axle
(1), at the basic section and the holders (2) at the 33 ft (10.1
m) section.
For removing the connection, the 33 ft (10.1 m) section is
locked in the slewing axle.
For establishing the connection, the 33 ft (10.1 m) section is
locked in the slewing axle and is secured with locking pins.
