Heavy Equipment Operators

Operators control machines that can kill in an instant, through rollovers, contact with ground workers or power lines, and slips getting on and off.

• Construction

Top hazards

• Rollovers on slopes, edges and soft ground
• Striking ground workers in blind spots
• Power line and underground utility contact
• Falls getting on and off machines
• Whole-body vibration, noise and dust
• Crush injuries during maintenance and attachment changes

Daily habits

• Walk around before every shift. See Equipment Basics.
• Wear the seatbelt every time.
• Know where everyone on foot is; stop if you lose sight of a spotter.
• Look up and call 811. Know where the lines are.
• Lower attachments and lock out the machine before maintenance.
• Use three points of contact; never jump down.
• Keep windows, mirrors and cameras clean.

Machine-specific pages: excavators, backhoes, skid steers, dozers, loaders, rollers.

Training and certification

There’s no single federal license for most heavy equipment, but employers must make sure operators are trained and competent. Common paths are union operating engineer apprenticeships, employer training and evaluation, community college programs and manufacturer training. Forklifts and telehandlers require formal evaluation; cranes require certification. See Crane Operators.

Your body over a career

• Whole-body vibration and long hours sitting can cause back problems. Keep the seat and suspension adjusted, and take stretch breaks.
• Noise: older and open-cab machines can damage hearing. Keep cab doors closed and wear hearing protection when needed.
• Dust: keep cab filters and seals in good shape, especially when working with silica-containing materials.
• Heat and cold: keep the cab’s air conditioning and heat working.
• Falls: most operator injuries happen getting on and off. Clean steps and use the handholds.

Communicating with the crew

• Agree on hand signals or radio calls with spotters, grade checkers and pipe layers before work starts.
• When someone needs to approach, stop, lower the attachment, set the controls in neutral and lock out the hydraulics.
• If you’re asked to do something unsafe, like digging inside a utility tolerance zone or lifting beyond the chart, say no and explain why.

Pre-shift checklist

• Walk-around done; leaks, damage and loose parts reported
• Seatbelt, horn, lights, backup alarm and cameras working
• Attachment and quick coupler locked
• Utility locates and overhead lines reviewed
• Ground workers’ locations and signals agreed
• Fluids checked; fire extinguisher on board
