Although it seems like everyone knows of the danger of being
struck by a crane's counterweight, this type of accident still persists in
industry. The following incidents illustrate the hazards faced by employees
working near cranes.
- An ironworker was tying rebar for a column in the close
proximity of a crawler crane. The crane was busy positioning other material on
the job site. The ironworker stepped backwards just as the crane swung it's
load. The ironworker was struck by the crane's counterweight.
- A laborer who was carrying a bag of cement inadvertently
walked behind a crane. The crane swung and the worker was pinned between the
counterweight and an adjacent pier.
- A laborer foreman stopped briefly between a lumber pile and
crane to watch it's operation. As the crane turned, the foreman stepped back to
provide additional room for the swing of the counterweight. The foreman tripped
and fell over a pile of lumber.
A common element in all of the above incidents was the failure
to keep the swing area of the crane's counterweight clear of workers and
materials or equipment that must be retrieved. Several solutions to this problem
KEEP WORKERS & MATERIALS CLEAR OF THE CRANE SWING
- Eliminate the problem -- Locate the crane in a position where
there will be no pinch points created between the counterweights and nearby
objects. The operator should only operate the equipment when the crane's swing
area is clear.
- Guard or warn of the hazard -- The counterweight's swing area
can be barricaded to keep workers out of the hazard zone. When appropriate,
warning tape can be used to identify the swing area. Painting a portion of the
counterweight a bright color helps to warn of the hazard by making it more
- Eye to eye contact -- All workers in the area should be told
to keep clear of the swing area. If material or equipment must be retrieved from
within the counterweight swing area, the worker should make positive visual
contact with the operator prior to entering the hazard zone. Once the worker is
done, the operator and worker should once again make positive visual contact so
that the operator knows it is now safe to continue full operation.
