Swing-away lattice
3.4 Description of the rigging work
H
3 - 82
If you have inclined the truck crane with the outriggers in order to set the
angle of inclination, then level the truck crane again now.
A crane example is illustrated in each of the following diagrams.
•
If necessary, relieve the pin (1) by raising
slightly.
•
Move the pin (1) into the position for the
required angle of inclination, e.g. 40°;
à
Setting the angle – with an auxiliary crane ,
p. 3 - 79.
•
Raise the main boom slowly.
In doing so, the head of the swing-away lat-
tice is pulled across the ground.
•
Lower the main boom until the swing-away
lattice head no longer touches the ground.
The swing-away lattice is inclined to the set
angle of inclination in the process, e.g. to 40°.
•
Fully retract the main boom without touch-
ing the ground with the swing-away lattice
(raise the boom now and again if neces-
sary).
•
Set the head of the swing-away lattice down
onto the ground.
