Overhead Crane Wiki: How to Use Crane Trucks
Cranes trucks have a myriad of uses from moving heavy objects to loading supply ships and hoisting equipment. That is why safe operation of these vehicles is critical. Operators must learn to use crane trucks properly and safely so costly accidents and serious injuries can be averted. Read on to learn more.
Things You’ll Need
-
Crane truck
-
Crane truck operator training and certification
-
Knowledge of crane truck operator hand signals
-
Ability to understand and use mathematical charts
- Attend a crane truck operator training or certification course. Visit the National Commission for the Certification of Crane Operators (NCCCO)’s website (www.nccco.org) to find out about programs available in your area.
- Learn how to manipulate the crane truck’s boom using foot pedals and levers to rotate, raise and lower it.
- Know your crane truck’s load capacity. If the load is over the limit, shut off the truck and lighten the load. Loads exceeding the vehicle’s limits should not be moved.
- Have an adequate number of workers with the crane truck at all times. Each rig should have an operator, a crew member who is responsible for the machine’s parts and a signal person.
- Ensure that your crane truck’s outrigger is hooked up correctly to a firm base.
- Calculate the correct counterweight. Use the mathematical formula based on the radius of the boom, the operating angle and the load’s weight. Avert the possibility of your crane truck leaning frontward by positioning counterweights on the underside of the vehicle’s cab.
- Mark all control buttons and switches with a label to indicate their function. Test each one to ensure it works properly, releases immediately and doesn’t stick.

- Clear the crane truck’s path of any obstacles and people prior to moving a load.
- Know the location and voltage of overhead power lines. De-energize the lines and erect insulated barriers before work starts. Establish a safe travel route and operate at a slower speed. If an operator has trouble seeing power lines or clearance while moving the crane truck a signal person should be on guard.
Tips & Warnings
- Only trained operators should use crane trucks.
- Workers should not be around a crane truck when in close proximity to power lines.
- Attend crane safety programs.
- Always stay clear of moving equipment.
- Prepare for an emergency. Know what to do in case of electrical, mechanical or power failures.
- Know how to extract an operator from the cab if necessary.
