Fall-back guard strut of the luffing jib
This additional page applies to all GMK7450 as of serial number 8031, except 8033, that are equipped with luffing jibs.
Reasons for the additional information
As opposed to the information in the lattice extension operating manual, the fall-back guard strut is:
–no longer hoisted during unrigging and rigging, –fastened with a tightening belt during transport. The risk of accidents during unrigging and rigging is reduced.
SRisk of damage to the fall-back guard strut
The fall-back guard strut can be damaged if it: –is not securely fastened during transport, –is hoisted during unrigging and rigging.
To avoid damage, fasten the fall-back guard strut and rig as described in the following:
When riggingCreate a joint between the luffing control arm and the fall-back guard strut
• Remove the pin from bore (6). Insert it into bore (5) and secure it.
• Join the stand (1) and the fall-back guard strut (3) with the pin (2).
• Remove the tightening belt from the strut(4).
When unriggingLoosen the joint between the luffing control arm and the fall-back guard strut
• Remove the pin from bore (5). Insert it into bore (6) and secure it.
• Secure the fall-back guard strut with a tightening belt at the strut (4); à During transport
• Pull the pin (2) out of the bore and set the stand (1) down.
• Insert the pin (2) into the bore on the fallback guard strut (3) and secure it.
During transport
The following information applies regardless of the means of transport.
SRisk of damage to the fall-back guard strut
The fall-back guard strut can be damaged if it is not securely fastened during transport. It may not move backwards or forwards, or laterally.
To avoid damage, fasten the fall-back guard strut as described in the following:
• Place the tightening belt (2): –from left side of the strut (1) –in front of the roll (3) completely around the fall-back guard strut, once, –to the right side of the strut.
• Tighten the tightening belt.
• Make sure that the pin is inside the bore (4) and is secured.
Validity
Slinging points
These additional pages apply to all GMK 7450 as of serial number 8001, that are equipped with luffing jibs.
Reasons for the additional information
The foot section of the luffing jib is frequently lifted with the short intermediate section attached together with the rear pendant link. The lattice extension operating manual is supplemented in the slinging points section by the following.
When lifting
GRisk of accidents if used improperly! Attach the boom sections to these slinging points only, as they will then automatically have the right centre of gravity. Use only the supplied lifting gear of sufficient lifting capacity.
• Only use the following slinging points.
