Which dock equipment is it?
The equipment around a dock opening does four jobs. It seals the gap around the trailer, absorbs trailer hits, holds the trailer in place, and signals when it's safe to load. Here's how to tell the pieces apart.
| Equipment | How you'd know it | Common problems | What to say |
|---|---|---|---|
| Dock seal | Foam pads covered in fabric on the sides and top of the opening; the trailer presses into them | Torn covers, crushed foam, gaps | "The seal at bay 2 is torn on the left side." |
| Dock shelter | A fabric hood on a frame that sticks out from the wall; the trailer backs inside it | Ripped curtains, bent frame | "The shelter frame at dock 5 got bent." |
| Dock bumpers | Rubber or rubber-and-steel blocks on the dock wall below the door | Worn through, torn off, loose | "The bumper at dock 3 is missing." |
| Vehicle restraint (dock lock) | A hook or arm at the base of the dock wall that grabs the trailer, with red and green lights | Won't engage, won't let go, lights wrong | "The restraint at door 9 won't release." |
| Wheel chocks | Wedges placed at the trailer wheels, loose or on a chain or arm | Missing, cracked, wrong size | "We're short on chocks at the north docks." |
| Signal lights | Red and green lights inside and outside the door | Wrong color, out, not changing | "The outside light stays red." |
| Dock lights | Swing-arm lights that shine into the trailer | Broken arm, no power | "The dock light at bay 7 is broken." |
Portable dock plates and boards have their own page: dock plate & dock board repair. Installed levelers are on the dock leveler page.
Dock seals and shelters
A dock seal is a set of foam pads that the trailer presses against. A dock shelter is a hood that the trailer backs into without touching much. Both close the gap around the trailer. When they're torn or crushed, heat, dust, rain and bugs get into the building. That matters most at cooler and freezer docks, where outside air works against the cold room.
| What you see | What a qualified provider may inspect | How to say it |
|---|---|---|
| Ripped fabric cover on a pad | Cover, foam, mounting | "The seal cover is ripped at bay 2." |
| Foam pads flattened and not springing back | Foam, backing, pad size | "The pads are crushed flat." |
| Loose or torn top curtain | Top curtain (head curtain), frame | "The top curtain is hanging." |
| Shelter frame bent after a trailer hit | Frame, side curtains, wall mount | "A trailer bent the shelter frame." |
| Daylight around the trailer when it's docked | Fit, pad size, alignment | "We see gaps around the trailer." |
Seal and shelter makers include Rite-Hite. The name is for identification only. Pads and shelters are sized to the opening, so replacements usually need measuring. If a provider takes the job, it measures. You don't need to.
Dock bumpers
Dock bumpers soak up the hit when a trailer backs in. When a bumper wears through or tears off, the trailer hits the dock wall, the leveler and the building instead. That can crack concrete and damage the leveler's front edge.
If the wall behind a missing bumper is cracked or broken, that concrete work is a separate job for a concrete contractor. The bumper itself is covered here.
Trailer restraints and dock locks
A vehicle restraint, often called a dock lock, holds the trailer against the dock so it can't pull away while people are loading. Many hook the bar under the back of the trailer (the rear impact guard). Some hold a wheel instead. Red and green lights tell the driver and the dock crew when it's safe.
OSHA's dockboard rule, 29 CFR 1910.26, says measures such as wheel chocks or sand shoes (stands that hold up the front of a trailer parked without its truck) must keep the trailer from moving while employees are on the dockboard. A restraint is one way docks do this. The industry standard for vehicle restraints is ANSI MH30.3.
| What you see | Why report it | How to say it |
|---|---|---|
| Restraint won't engage the trailer | The trailer may not be held | "It won't lock onto the trailer at door 9." |
| Restraint won't let go | The trailer can't leave | "The restraint won't release." |
| Inside and outside lights don't agree | Drivers and crews get mixed signals | "Inside shows green, outside shows red." |
| Alarm keeps sounding | The system thinks something's wrong | "The restraint alarm won't stop." |
| Hook or arm bent after a hit | It may not hold | "A trailer bent the hook." |
Don't override, bypass or force a restraint. Don't move a trailer against your site's rules. Report what you see and follow your facility's process.
Lights and interlocks
Some docks link the restraint to the leveler or the door. The leveler or door won't run until the restraint grabs the trailer. That's on purpose. If a linked system stops working, report which bay and what the lights show. Wiring for restraints, lights and interlocks is electrical work, and TDLR licenses electricians in Texas.
If a trailer is at the bay, say so first.
What happens when you call?
You call (385) 325-7138 and describe the equipment and the facility. Calls may be shared with an independent commercial dock-and-door repair company. That provider confirms availability, scope, pricing, and service terms.
- Call and describe it. Give the address, the dock number and what's damaged. More than one problem at one bay? Say them all on one call.
- The call may be shared with an independent commercial dock-and-door repair company.
- If a provider takes the job, it inspects, quotes and schedules the work under its own terms.
Example of what to say (not a real call): "The trailer restraint at door 9 won't release at our warehouse in McAllen, and I can give you the address."
If you reach voicemail, leave the facility address, the door or dock number if known, what's wrong, and a callback number.
What affects the price?
We can't quote your exact dock-equipment repair from a web page. The price depends on the equipment, the fault, parts, and access. Here's what to ask before you authorize work.
| What changes the price | Why | Ask |
|---|---|---|
| Seal or shelter size and type | Parts are made to fit the opening | "What size are you replacing?" |
| New covers versus new pads | A cover costs less than a whole pad | "Can you replace just the cover?" |
| Shelter frame damage | Frames may need straightening or replacing | "Is the frame bent or broken?" |
| Bumper type | Plain rubber costs less than steel-faced | "Which bumper fits our trailers?" |
| Number of bays | More bays, more parts | "Can you price all the bays at once?" |
| Restraint type | Hook and wheel restraints use different parts | "Which part of the restraint failed?" |
| Lights, controls and wiring | Electrical work adds time | "Is this a wiring or a mechanical problem?" |
| Cooler or freezer docks | Special pads and access | "Is there anything different about a cold dock?" |
| Parts lead time | Custom sizes may need ordering | "Is the part in stock?" |
Ask whether there's a trip or diagnostic charge, and whether you're getting an estimate or a final quote.
Call about the bay and ask how the visit is charged.
Planned dock-equipment checks
Planned checks on restraints, seals, bumpers and lights catch wear before something fails. When you call, say it's planned work and how many docks you have. For planned leveler work, see the dock leveler page. For planned door work, see commercial garage door maintenance.
Local checks
New restraints, lights or interlocks may involve wiring, which is electrical work. TDLR licenses electricians in Texas. Adding a wired restraint or signal lights is the part most likely to raise a permit question. Repairs, replacements and new installs can need a permit, depending on the address. Ask the provider, or the office that covers the facility:
| If the facility is in… | Office |
|---|---|
| McAllen | City of McAllen Permits |
| Pharr | Pharr Building Safety |
| Edinburg | Edinburg Building Safety |
| Outside city limits | Hidalgo County Permitting |

Dock equipment questions
Is a dock seal the same as a dock shelter?
No. A seal is a set of pads the trailer presses into. A shelter is a hood the trailer backs into. Both close the gap around the trailer.
Do we need a restraint if we use wheel chocks?
OSHA's dockboard rule says measures such as wheel chocks or sand shoes must keep the trailer from moving while employees are on the dockboard. A restraint is another way to do it. The provider can walk you through the options for your dock.
Why won't the leveler work until the restraint locks?
Some docks link them on purpose, so no one loads an unsecured trailer. Report it. Don't work around it.
Can a torn seal be patched?
Sometimes just the cover gets replaced. Crushed foam usually means a new pad. The provider looks and tells you which.
Can several bays be looked at on one visit?
Ask when you call. The provider confirms what it can do.
Does this include replacing damaged concrete?
No. Concrete, dock walls and pits need a concrete contractor.
