13.3.3 Putting the truck crane on the wheels
Lowering wheels
• Retract the supporting cylinders until all wheels are just above the ground.
• Switch on the suspension – the symbol must be green;
à Switching the suspension on/off, p. 5 - 16.
Now lower all wheels to the ground.
G
Danger of overturning by unevenly retracting the outrigger cylinders!
Retract the outrigger cylinders evenly! This prevents the truck crane from
overturning while retracting individual outrigger cylinders.
S
Risk of damage to the axle lines!
Retract the outrigger cylinders evenly! This prevents excessive strain on the axle
lines.
G
Danger of overturning when switching on the suspension!
You may under no circumstances switch on the suspension while the rigged
truck crane is on wheels. Switching on the suspension would cause the suspen-
sion struts to be suddenly collapsed and damaged, and the truck crane could
overturn.
