Do not attempt to operate the crane unless you are trained and thoroughly familiar with all
operational functions. Controls and design may vary from crane to crane, therefore, it is important
that you have specific training on the particular crane you will be operating.
Training is ESSENTIAL for proper crane operation. Never jeopardize your own well-being
or that of others by attempting to operate a crane on which you have not been trained.
You must be mentally and physically fit to operate a crane. Never attempt to operate a
crane while under the influence of medication, narcotics, or alcohol. Any type of drug could impair
physical, visual, and mental reactions and capabilities.
CRANE STABILITY/STRUCTURAL STRENGTH.
To avoid death or serious injury, ensure that the crane is on a firm surface with load and
crane's configuration within capacity as shown on the crane's load rating chart and notes.
Do not lift loads unless the outriggers are properly extended and the crane leveled. On
models equipped with outriggers that can be pinned at the mid-extend position, the outriggers must
also be pinned when operating from the mid-extend position.
This crane should have a functional load moment indicator and control lock-out system.
Test daily for proper operation. Never interfere with the proper functioning of operational aids or
warning devices.
Before swinging the superstructure over the side when the outriggers are retracted, check
the load chart for backwards stability.
Long cantilever booms can create a tipping condition when in an extended and lowered
position. Retract the boom proportionally with reference to the capacity of the applicable load chart.
Check crane stability before lifting loads. Ensure the outriggers (or tires if lifting on rubber)
are firmly positioned on solid surfaces. Ensure the crane is level, brakes are set, and the load is
properly rigged and attached to the hook. Check the load chart against the weight of the load. Lift
the load slightly off the ground and recheck the stability before proceeding with the lift. Determine
the weight of the load before you attempt the lift.
