25. OSHA-Identified Crane Hazards
OSHA's analysis identified the major causes of crane accidents to include:
• Boom or crane contact with energized power lines (nearly 45% of the cases)
• Under the hook lifting device
• Overturned cranes
• Dropped loads
• Boom collapse
• Crushing by the counter weight
• Outrigger use
• Falls
• Rigging failures

26. Who is at
Risk?
• Operators
• Persons at Crane Site

27. Power Lines
The greatest risk for cranes is contacting power lines.

28. Stay clear from power lines
at least 10 feet under
50kv.
If the voltage of the power
lines is unknown, stay at
least 20 feet away or more
and immediately contact
your employer so that they
may contact the utility
provider to determine
voltage of the power lines.
Warning: Power lines can
carry 50kv, 250kv, 350kv,
500kv or more. The higher
the kv the greater the risk of
arcing and employee injury
and property damage.

29. Improper Load
Improper loads or speeds can result
in the tipping of the crane.

31. Improper Load

32. Free Fall Features on Crane

33. Guard Moving Parts
Unguarded
Chain
Drive
Guard moving parts such as gears or belts.

34. Swing Radius
Stay out of the swing radius of the crane –
make sure there are barrier guards showing swing radius.

35. Operator Visibility
Broken
Window
Make sure broken
windows or other
obstructions do not
prevent the operator
from seeing.

36. Ladders
Ladder
Use ladders to get to the upper portion of the cab.

37. Guardrails
Runways and
steps need to have
guardrails,
handholds and slip
resistant surfaces.

38. Planning Before Start-Up
• Level the crane and ensure support surface is firm and able to support the load.
• Contact power line owners and determine precautions. Know the location and
voltage of overhead power lines.
• Know the basic crane capacities, limitations, and job site restrictions, such as
the
location of power lines, unstable soil, or high winds.
• Make other personnel aware of hoisting activities.
• Barricade areas within swing radius.
• Ensure proper maintenance and inspections.
• Determine safe areas to store materials and place machinery.

39. Suspended Loads
Don’t stand under
suspended
loads.

40. Common Reasons Accidents Occur
• Instability – unsecured load, load capacity exceeded, or
ground not level or too soft
