If necessary, remove any ice and snow from the truck crane before com-
mencing crane operation.
Keep all handles, steps, step treads and ladders free of dirt, snow and ice.
Keep all electric and hydraulic connections free of dirt. Check the connecting
points for dust, foreign bodies and moisture before installation. This also
applies to protective caps and bridging plugs.
Check all operating and control elements in the crane cab before starting the
engine.
After starting the engine, take note of all the lights and control elements.
Make sure that there are no unauthorised people in the vicinity of or on the
truck crane during rigging work or crane operation. Cordon off the danger
area clearly and mark the area as such.
When lifting a load, balance out the increase in working radius caused by
flexure of the boom by raising the boom, so that the load is lifted vertically
and does not drag, injure helpers or topple into the hoist rope (e.g. from a
vehicle or scaffolding). Inform any banksmen and helpers about this issue
as well.
Support the truck crane with the outrigger span required for the currently
rigged counterweight before turning the superstructure.
Always level the truck crane before operating the crane.
Only use parts of equipment (counterweight sections, lattice extension) that
belong to your truck crane. Both the truck crane and the equipment must
have the same serial number.
Lifting loads simultaneously with two cranes is particularly hazardous.
Carry out this type of work with special caution.
Always set the load down when there is a break in work, and never leave the
truck crane whilst a load is raised.
Whenever you leave the truck crane, secure it against unauthorised use.
