What the door is

Loading dock doors, described plainly.

A commercial sectional door with a row of windows

A loading dock door is the overhead door in a dock opening: usually a sectional door, sometimes rolling steel, working harder than almost any other door on a site because it cycles with every delivery.

It also works in the most hostile position on the building. Trailers reverse into it, forklifts pass through it, the seal takes a beating from both, and the whole assembly lives with vibration no residential door ever sees.

One boundary worth stating plainly, because it saves everybody a call: we work on the dock door, its counterbalance, its track and its operator. Dock levelers, vehicle restraints and the control systems around them are not part of what we do.

Where it is usually working

Distribution and fulfilment Doors cycling constantly, where downtime is measured in trailers.
Food and cold storage Where a door that will not seal is a temperature problem as well as a door problem.
Manufacturing shipping bays Wide openings, heavy traffic, and usually a production line behind them.
Retail and grocery delivery One or two bays taking every delivery the store gets.
Contract and third-party logistics sites Many identical bays, where a standard specification across them pays for itself.

What actually fails

The six things we are called out for.

Described the way a facilities manager sees them rather than by part number. If what your door is doing is not on this list, call and describe it — a person answers 24/7.

Impact damage A trailer or a forklift into the door. Sections, track, brackets, or all three at once.
Springs and cables at dock cycle rates This is the door that reaches its cycle count first, and it usually fails at the least convenient moment.
Track pulled out of line Vibration and contact loosen brackets, and a door that has been running slightly out of true eventually leaves its track.

Bottom bar and perimeter seals Weather, grit and pests in, conditioned air out.
Operators and safety devices Controls, limits, photo-eyes and edge devices on a door that runs all day.
Openings that never quite got fixed The bay that has been “managed” with a strap or a wedge for months. Those are the ones that fail badly.

What to have ready

Five facts that sharpen the estimate.

A photo of the opening and the door label covers most of it.

The opening and the approach Width, height, the largest trailer that backs in, raised dock or at grade, and bollards or bumpers beside the door.
Track and headroom Standard lift, low headroom, vertical or high lift, and what hangs above: pipes, ducts, sprinkler lines.
Door type and label Sectional or rolling, wind or impact rated. Send the maker’s label; a look-alike part can be weaker.

Cycles per day How often each door runs in a shift, and whether the bay works round the clock.
What hit it What struck it and where, with photos.

The rules around the door

What a dock supervisor should know.

Three rules that reach a dock door. Not legal advice.

OSHA 1910.28: dock edges Dock edges 4 feet or more above the lower level need a guardrail, safety net or personal fall protection, with a narrow working-side exception. DASMA adds: open a dock door only with a vehicle in the opening or a barrier in place.
UL 325: entrapment protection A door that can close by remote or timer needs a monitored external device, such as a photo-eye or sensing edge. DASMA says primary photo-eyes sit no higher than six inches above the floor.

OSHA 1910.147: outside servicing Where the lockout/tagout standard covers the work, you and the outside employer must exchange procedures. Whether it covers a dock door is your safety lead’s call.

Upkeep for a busy door

How often to look, and who does it.

The maker’s manual sets the schedule for your door. These are the baselines published sources give.

After an impact that damages the door Stop running it under power. One maker’s manual says not to keep operating a damaged door.
Monthly Test the photo-eyes as the operator’s instructions describe; look over the track for damage and loose bolts.

Every six months, or as required Rollers, hinges, hardware, bottom seal, cables, set screws, lubrication. Spring work is for a trained technician.
Rolling steel dock doors DASMA says a trained technician should inspect at least annually, or as the maker recommends.

What a visit involves

The estimate is the document you route.

A technician looks at the opening with you and writes the price before anything starts. Nothing begins until it comes back approved, and the invoice matches the number you approved.

Tell us which bays have to stay live And when the trucks run. Dispatch schedules around the dock rather than around our day.
One visit, every door, where that helps If a technician is on site, having the other bays looked at is the cheapest inspection you will get.
Made safe, then finished Where the work cannot be finished in one visit, we leave the opening as secure as it can safely be made and book the return.
A written quote to your approver before any work starts The estimate is the document you route. Nothing begins until it comes back approved, and the invoice matches the number approved.
5-Year Warranty on All Parts & Labor. Five years on parts and labor, every repair and every install.

Describe it however makes sense to you

Tell us which opening, and when it has to run.

Tell us about the opening, the door and the traffic it has to carry. A technician measures on site, and nothing is ordered until the written estimate comes back approved.

No spec sheet needed. The opening and how the dock runs are enough to start.
The written estimate is free. Nothing owed if you pass.
Nothing is ordered until the estimate comes back approved.

Not this door?

The other commercial openings.

Each page says what that door type is, what fails on it, and what a visit involves. Or start at the commercial overview.

Sectional overhead doors The door most service bays actually have. Rolling steel doors One curtain, one barrel, and no room for guesswork. High speed doors Built to spend as little time open as possible.

Questions people ask

Straight answers.

Do you work on dock levelers and restraints?

No. We work on the dock door itself — the counterbalance, the track, the seals and the operator. Dock levelers, vehicle restraints and their control systems are outside what we do.

Can you come outside our operating hours?

A person answers 24/7 and we schedule around the dock. Tell dispatch which bays have to stay open and when the trucks run.

A bay is down right now and we cannot ship

Say that on the call. A failure that stops a dock is one of the situations that changes how a job is handled rather than being scheduled behind everything else.

What counts as one cycle on a dock door?

DASMA’s sectional door standard counts one cycle as a trip from closed to fully open and back to closed. A door opened once and held through a whole trailer load is one cycle. Spring life is counted in cycles.

Can we keep running a door a forklift hit?

Not on the operator if it was damaged. One maker’s manual says not to keep operating a damaged door that needs extra effort to open or close, or to power it electrically. Keep people clear and tell us what hit it.

Why does the door only close while I hold the button?

Often the operator is doing what UL 325 requires. When an external entrapment device such as a photo-eye fails, operators made since August 2010 close only under constant pressure, and remote or timer controls can only open.

Does leaving a dock door open all shift hurt it?

It can. DASMA notes that doors left open for extended periods regularly expose springs to more temperature, moisture and air-quality variation, and that acids containing chlorine can corrode them. Wash bays should be reviewed for corrosion.

The operator keeps failing. Is it the operator?

Sometimes the door is the cause. DASMA notes an unbalanced or jerking door puts excess wear on an operator and can shorten its life, and a door that drifts after the operator stops should be checked for balance.

Are you insured?

Yes. Insured & Bonded, with Background-Checked Technicians.

How does approval work on a PO?

The written estimate is the document you route. Nothing starts until it comes back approved, and the number on the invoice is the number you approved.

Do you charge to come out?

No. We look at the door with you and give you a written estimate. You approve it before any work starts, and there is no charge if you decline.

What does the warranty cover?

Five years on parts and labor, every repair and every install. The scope is on the estimate you approve and on the invoice.
