3.7. Use of the crane
Starting crane operation
DANGER
• Wear a safety helmet (compulsory in some countries!).
• Check that the ground is sufficiently flat and firm.
• To ensure that the vehicle stays in its position, always engage the parking brake
and place chocks under the wheels.
• Check that the ground is not undermined. Look out for sewers, cellars,
excavations etc.
• The stabiliser legs must not be able to sink in! Use support plates that are large
and firm enough for your crane. The plates must not bend under load.
Check that the support plate as, it comes under load, is not pushed into the
ground.
• Ensure you can see the stabiliser legs and stabiliser extensions when you are
operating them.
• Do not lower the stabiliser legs on the edge of an embankment, soft shoulder,
slope etc.
Lower the stabiliser legs only on to a flat and firm surface.
DANGER
• Do not stand in front of the hydraulically
operated stabiliser legs when you are
operating them!
• Never use the stabiliser legs as a parking
brake, since the vehicle could start to
slide.
• Slide the stabiliser extension, on both
sides of the vehicle, out completely if
possible. Then lower the stabiliser legs for
support.
• Never operate the stabiliser legs, while the
crane has a load!
