Learning Objectives/Outcomes.
Upon completion of the lesson, participants will be able to:
1. List the four major causes of crane accidents.
• Contact with power lines
• Overturns
• Falls
• Mechanical failures
2.Describe the pre-planning that is required before putting a crane in use.
• Ensure the crane is on a firm, supported surface, and is level within 1%
• Determine the location of overhead power lines
• Know the job site conditions (e.g. unstable soil or high winds)
• Make other personnel on the job site aware of hoisting activities
• Barricade access within the swing radius
• Ensure a competent person inspects all machinery and equipment prior to each use
• Consider the load limiting factors
• Consider lifting principles
3. State the two main precautions that apply to working with cranes near power lines.
• Stay clear of all power lines. Clearance distance should be at least 10 feet, and at least 16 feet for 750 kV or higher.
• Have an observer or “spotter” who has a clear view of the power lines and the working crane at all times. The crane operator and observer must be able to see each other and communicate.
