11. Working procedures – Lorry Cranes

11.1 General


  • Lorry cranes may only be used by qualified personnel.

  • Crane operators must ensure that the equipment is in a safe
    condition.

  • There must be sufficient light for the crane operator or the
    signalman to see the load. There must always be a visual and/or
    preferably a two-way communication between the crane
    operator and the signalman.

  • The crane operator shall not perform multiple tasks to avoid
    distractions from crane operations.

  • Mobile phones shall not be used during lift operations. Unless it
    is a part of the planned communication for the lifting operation.

  • The crane operator shall wait for signal or see the entire load
    before lifting starts.

  • Guidelines shall be used to control extended, heavy or difficult
    lifts.

  • The crane operator shall not put the controller away if there is a
    load in the hook.

  • The crane operator is responsible for ensuring that all crane
    operations are performed correctly. In case of doubt, the crane
    operator will refuse to lift until safe conditions are met.

  • Action must be taken against danger of collision when multiple
    cranes are in the same working area. Measures such as sector
    limitation, communication, transport directions, etc. shall be
    considered. Document the actions and responsibilities in the
    SJA.


11.2 Working procedure

Arrangement

  • Crane leg pads should always be used when lifting.

  • The base for the crane leg pads must be secured in order to
    avoid.

  • Make sure the stability is horizontal and that the crane leg pads
    correctly aligned and positioned. Verify that there is pressure
    on all support legs.


Checklist before starting a lift operation

  • Ensure that the lift operation is done within the range of the
    lifting capacity of the lorry crane.

  • Check that the safety equipment is working properly.

  • Correct lifting equipment for the task.

  • Check wind conditions.

  • The work must be stopped, and your supervisor must be
    contacted if there are any doubts about the lift operation.


Checklist during lift operations

  • Clear communication between crane operator and signalman.

  • Visual and/or preferably a two-way communication between
    crane operator and signalman.

  • No lift operation above people.

  • Make sure the crane is stable.


Checklist after the lift operation

  • Check if lifting equipment and crane are in good condition.


Driving on the road
Make sure the lorry crane is prepared for safe and legal transport
on road, that it is equipped according to the conditions and that
you have valid dispensations where required.

Hazardous situations:
- Instability. Focus on the type of road (ex bearing capacity).
- High/low voltage lines in the air and in the ground.
- Remember that plastic support plates can slide on snow.
Preferably use sand or gravel underneath.
- Road verges that cannot handle the load of larger vehicles.
- Load above people.

Instructions:

  • Lorry crane manual


Quality control:

  • Lifting equipment must be certified and be marked with SWL or
    WLL

  • Daily inspection (machine report) of lifting devices.
