Forklift Hit an Overhead Door? What to Do Next

Quick answer: If a forklift hits an overhead door, stop using the door immediately, lock out the operator, and keep people and equipment out of the area under and around it. Don't try to raise or lower a bent door, and don't let staff pry panels or hammer tracks straight. A hit door can be out of balance with springs and cables under extreme tension. Photograph the damage, report it, and call a commercial door technician to secure the opening and assess repair or replacement.

Forklift impacts are one of the most common causes of commercial door damage. A mast that isn't lowered, a load that's taller than expected, or a driver who misjudges a door that's still opening can bend panels, kink tracks and knock the whole system out of alignment in a second. What you do in the next few minutes matters for your crew's safety, your building's security and how much the repair will cost.

What to do right after a forklift hits a door

1. Stop operating the door. Don't push the button to see if it still works. Running a damaged door can pull it further off track or drop it.
2. Lock out and tag out the operator. Turn off power to the electric operator using your facility's lockout procedure so no one can run it.
3. Clear and mark the area. Keep people, forklifts and pallets out from under and around the door. Cone or tape off the opening.
4. Don't try to force it. Don't lift, lower, pry or hammer on panels, tracks or curtain slats. Never touch springs, cables or counterbalance parts.
5. Check for injuries and report the incident according to your company's safety process.
6. Document the damage. Take photos of the door, tracks, operator, the forklift and the floor area. Note the time and what happened.
7. Call a commercial door technician. Tell them what kind of door it is, whether it's stuck open or closed, and whether the opening needs to be secured tonight.

Why a damaged commercial door is dangerous

Commercial sectional and rolling steel doors are heavy, and they're held up by springs that store a great deal of energy. When a forklift hits a door, the impact can:

• Bend or crease panels so they bind in the tracks
• Knock rollers out of the tracks or bend track sections
• Kink or fray lift cables, or knock them off their drums
• Bend the bottom bar or slats on a rolling steel door
• Damage the operator, drive chain, limit switches or safety edge
• Pull wall-mounted brackets or the header away from the building

Any of these can leave a door that looks "mostly fine" but is no longer supported evenly. A door in that condition can drop unexpectedly when someone tries to move it.

Repair or replace after an impact?

It depends on what was hit and how hard. A technician will usually look at:

• How many sections or slats are damaged. One or two dented sections can often be replaced. Widespread damage may make a new door the better choice.
• Track and bracket condition. Bent track can often be replaced in sections.
• Springs, cables and drums. An impact can shock-load these parts. They're inspected and replaced if damaged.
• The operator. Motors, gearboxes and safety devices are tested after the door is repaired.
• Part availability. Matching sections for an older or discontinued door may not be available.
• The door's age and repair history. A door that's already been hit several times may be due for replacement.

Our article on when to repair or replace a commercial overhead door covers this decision in more detail.

Common reasons forklifts hit doors

• Driving through before the door is fully open
• The mast or load is higher than the door opening
• Poor visibility at the opening, especially with large loads
• Doors that open too slowly for the traffic at that opening
• Doors that close on a timer or sensor while traffic is still passing
• Tight turns into the opening and no protection on the door frame

How to prevent forklift door damage

Protect the door frame and tracks

Bollards and track guards placed at the sides of the opening keep forklifts from clipping the tracks and frame. Flexible polymer bollards absorb impacts and help protect both the building and the equipment. See our safety bollards and impact protection.

Choose the right door for the traffic

High-traffic openings are where impacts happen most. High-speed doors open and close quickly, which keeps traffic moving and reduces the chance of hitting a door that isn't fully open. Some high-speed models are built to break away or recover after an impact instead of being destroyed. For interior openings, environmental control products like strip doors can be a lower-cost option for separating areas.

Improve activation and visibility

Motion sensors, pull cords, loop detectors and clearly marked stop lines help drivers know when a door is ready. Good lighting and warning lights at the opening help too.

Train drivers and set clear rules

OSHA's powered industrial truck standard requires forklift operators to be trained and evaluated. Include door safety in that training: wait for the door to fully open, lower the mast before the opening, and never drive through a moving door.

Keep doors maintained

A door that opens slowly, stops partway or reverses unexpectedly is more likely to be hit. Regular maintenance keeps doors moving at the right speed and their safety devices working.

Keep a damaged dock from shutting down operations

A door stuck open is a security and weather problem. A door stuck closed can shut down a dock. Ask your technician whether they can secure the opening first and complete the full repair once parts arrive. Facilities around Battle Creek's Fort Custer Industrial Park, Jackson's manufacturing corridor and Ann Arbor's research and tech campuses often can't afford a dock door down for long, which is why planning ahead matters.

Our Preventative Maintenance Program has free enrollment, discounted labor rates, priority scheduling and 24/7 same-day service, with a detailed report for each door. Members are already in our system when something goes wrong.

Frequently asked questions

Can I keep using a commercial door after a forklift hits it?

No. Even if it still moves, it may be off balance or have damaged springs, cables or tracks. Lock out the operator until a technician inspects it.

Can a single damaged section of an overhead door be replaced?

Often, yes, if matching sections are available and the rest of the door is sound. Widespread damage may make replacement the better choice.

How can I stop forklifts from hitting our dock doors?

Combine bollards and track guards, faster doors at high-traffic openings, clear activation and warning lights, and driver training on door safety.

Does a forklift impact damage the door operator?

It can. The motor, drive, limit settings and safety devices should all be inspected and tested once the door itself is repaired.
