Key Questions
The following key questions are answered in this module:
Why is it important to operate a crane safely?
There is great potential for accidents, injuries, and deaths. Every year, crane-related accidents cause hundreds of injuries, dozens of deaths, and millions in property damage.
Are pre-operation inspections necessary?
Yes, inspect the crane, rigging, and work area before operating.
What is the load capacity?
The weight that the crane and rigging can lift safely.
Is the lifting capacity greater when the sling angle is higher or lower?
The lifting capacity is greater when the angle is close to 90 degrees, and is less when the sling angle is less (such as 15 degrees).
Is it important to beware of people when operating a crane?
Yes, always. Never operate a crane in a way that might put a person at risk of injury.
What is side loading?
Lifting a load from the side-this increase stress on the crane and shouldn't be done.
What are tips for safe lifting?
Make sure the load is stable in rigging, make sure attachments are centered in hook bowl, that safety latches on hooks are closed, and never use the tip of a hook to lift a load.
What are tips for safely moving a load?
Move smoothly, keep load stable, avoid shock loading, keep load as close to floor as possible, be cautious so slings and hoist lines don't get tangled or twisted, use tag lines, and stop periodically during long movements to make sure everything's OK.
What are tips for safely putting down a load?
Come to a stop slowly, minimize swinging of load, make sure load is stable, and land the load fully.
What should you do if a crane or rigging appears to be overload?
Tell a supervisor and have a qualified person inspect it before trying to use it again.
What are typical members of a multi-person crane crew?
Crane operator, tag line holder, signal person, and rigger. It's important that everyone knows their role clearly.
What type of PPE should one use?
Gloves, steel-toed shoes, hard hat, and other PPE circumstances call for, such as eye protection and hearing protection. Avoid wearing loose, dangling clothes or jewelry.
