Which dock equipment is it?
Everything on this page sits around the trailer opening. The leveler, the door and portable plates have their own pages.
| Equipment | What it looks like | What to say on the call | Page |
|---|---|---|---|
| Dock seal | Thick foam pads covered in fabric on the sides and top of the opening. The trailer presses into them | "Dock seal at door 2 is torn" | This page |
| Dock shelter | A frame with fabric curtains that the trailer backs into, without pressing hard against pads | "Shelter curtain is ripped" | This page |
| Dock bumpers | Rubber, laminated or steel-faced blocks bolted to the dock wall | "Two bumpers are broken off" | This page |
| Trailer restraint (vehicle restraint, dock lock) | A hook or bar at the dock face that grabs the trailer's rear bumper or wheel, with red and green lights | "Restraint at door 7 won't release" | This page |
| Communication lights | Red and green lights inside and outside that tell the driver and dock crew when it's safe | "The outside light stays green" | This page |
| Dock lights | Swing-arm lights that light up the inside of the trailer | "Dock light at door 4 is out" | This page |
| Wheel chocks | Wedges placed at the trailer's wheels | "Chock is cracked" | This page |
| Dock leveler | The built-in ramp in the dock floor | — | Dock leveler repair |
| Dock plate or board | A loose portable bridge | — | Dock plate repair |
| Dock door | The overhead or roll-up door itself | — | Overhead door repair |
Seals and shelters
A dock seal or shelter closes the gap between the building and the trailer. When pads tear or curtains rip, weather, bugs and conditioned air get through. At cold storage docks, that gap is where cold air escapes and frost builds up.
Common repairs include replacing worn pad covers, replacing whole pads, replacing torn shelter curtains, and fixing a frame that got hit. Sometimes the fix is a different size or style, because the trailers using that door have changed.
What to report: which doors, which side is torn (left, right or top), and whether the frame is bent. If you know the trailers are mostly one size, say so.
Bumpers
Dock bumpers take the hit when a trailer backs in. They protect the wall, the leveler and the door frame. Once a bumper cracks, wears down or falls off, the trailer can hit concrete or steel instead.
What to report: how many doors, how many bumpers, and whether the bolts or wall behind them look damaged. Replacing bumpers usually means matching the size and type to the dock height and your trailers.
Trailer restraints
A trailer restraint — also called a vehicle restraint, truck restraint or dock lock — holds the trailer at the dock so it can't pull away or creep while a forklift is inside. Most use a hook or bar that grabs the rear impact guard (the bumper bar under the back of the trailer). Some grab a wheel instead. Lights tell the driver and the dock crew whether it's locked.
OSHA doesn't require a powered restraint. But OSHA does require that trailers be kept from moving while a dockboard is in use (29 CFR 1910.26). If your facility uses restraints and one isn't working, follow your facility's own procedure for securing trailers at that door. The industry standard for vehicle restraints is ANSI MH30.3 (2022 edition) (MHI). For the full comparison, see vehicle restraints vs. wheel chocks.
Report it. Don't bypass it. Never override a restraint or its lights to keep loading. Say exactly what it's doing:
| What the restraint is doing | Why it matters | How to report it |
|---|---|---|
| Light stuck on red or green no matter what | The crew and the driver can't trust the signal | "Lights at door 7 are stuck on green." |
| Hook won't come up to grab the trailer | The trailer isn't held | "The hook won't engage." |
| Hook won't let go, and a trailer is still at the dock | The driver may try to pull away | "The restraint won't release, and a trailer's still here." |
| Hook grabs but slips off | The trailer may not be held | "It grabs, then lets go." |
| Door or leveler won't work until the restraint locks | An interlock ties them together | "The leveler won't work because the restraint won't lock." |
| Hit by a trailer, bent or scraped | Damage can stop it from working | "A trailer hit the restraint at door 3." |
Labels you may see: Rite-Hite (Dok-Lok), Blue Giant and Pentalift make vehicle restraints. Mention the brand only if you already know it.
Communication lights, interlocks, dock lights and chocks
Communication lights are the red and green lights inside and outside the dock. They work with the restraint and tell each side when it's safe. If they disagree with what the restraint is doing, report it as a restraint problem.
Interlocks tie equipment together so things happen in a safe order — for example, the leveler won't work until the restraint locks, or the door won't open until the trailer is secured. Never bypass one. Report what won't work and what it's waiting on.
Dock lights swing into the trailer so drivers can see. A broken arm or dead light is a simple call, but say if wiring is damaged.
Wheel chocks are wedges at the trailer's wheels. Cracked or missing chocks are usually replaced, not repaired.
A trailer is stuck in a restraint — what now?
Call and say it first, with the door number and address. Keep people clear of the trailer and the dock face. Tell the driver not to pull away. Don't try to free the hook yourself. Follow your facility's own procedure. Whether and when someone can come is confirmed by the provider on the call.
If a trailer is stuck at the dock, say so first.

What affects the price?
We can't quote your dock equipment repair from a web page. The price depends on the equipment, the damage, parts, and access. Here's what to ask before you authorize work.
| Price driver | Why it changes the price | Ask |
|---|---|---|
| Seal: pad cover vs. whole pad | Covers cost less than full pads | "Can you replace just the cover?" |
| Shelter: curtain vs. frame | A bent frame is more work than a curtain | "Is the frame damaged too?" |
| Bumpers: count, type, anchors | Steel-faced and laminated bumpers differ, and damaged wall anchors add work | "How many, what type, and are the anchors OK?" |
| Restraint type and parts | Hook and wheel restraints use different parts | "Which part failed? Is it in stock?" |
| Controls and electrical | Lights, controls and interlocks are wired | "Does this need an electrician?" |
| Several doors at once | Doing more doors on one visit can change the price | "Is there a different price if we do all the doors?" |
| Visit or diagnostic charge | Many companies charge to come out and look | "Is there a trip charge?" |
Ask whether you're hearing a call-out fee, a starting price, a fixed price for a set scope, an estimate or a final quote.

Long Island rules for dock equipment
- Electrical: restraints, lights and interlocks are wired. Suffolk County licenses master electricians except in towns or villages with their own law (Suffolk Code Ch. 563). In Nassau, towns such as Hempstead, North Hempstead and Oyster Bay license electricians.
- Safety at work: private warehouses fall under federal OSHA (OSHA). How trailers are secured is part of your own facility's safety program.
- Permits: replacing seals, bumpers or a restraint is usually ordinary repair work. New wiring or structural changes are when to ask the town, city or village building office.
The provider and the issuing office confirm what applies. The full table is on the Long Island dock and door repair page.

Questions about dock equipment repair
Do we need a trailer restraint?
OSHA doesn't require a powered restraint, but it does require trailers to be kept from moving while a dockboard is in use. How your facility does that — restraints, chocks, or both — is set by your own safety program.
Can you replace just the dock seal pads?
Often, yes. Worn covers or single pads can be replaced without a whole new seal if the frame and backing are sound. Ask the provider after they look at it.
The restraint light is stuck on red — what should we do?
Treat that door as not ready. Follow your facility's procedure for securing trailers and call to report it. Don't override the restraint or its lights.
Do you repair boat docks?
No. This line is for loading docks at commercial buildings. A marine contractor is the right call for boat docks.
