Which dock equipment is it?
A loading dock has a lot of parts with a lot of names. This table helps you name what's broken. If you're not sure, describe it — that works too.
| What it looks like | Name | What to mention | Where it's covered |
|---|---|---|---|
| Thick foam pads around the door that press against the trailer | Dock seal | Torn, flattened, missing pads | Seals and shelters |
| A fabric frame or curtains around the door that the trailer backs into | Dock shelter | Torn fabric, bent frame | Seals and shelters |
| Pads or bags that puff up around the trailer | Inflatable seal or shelter | Won't inflate, torn | Seals and shelters |
| Rubber or layered blocks on the dock face | Dock bumper | Split, worn, missing | Dock bumpers |
| A hook or bar that grabs the back of the trailer | Trailer restraint, vehicle restraint, dock lock | Won't catch, won't let go | Trailer restraint repair |
| A block at the trailer wheel, loose or on an arm | Wheel chock | Damaged, missing | Trailer restraint repair |
| Red and green lights inside and outside | Communication lights | Wrong color, out | Dock lights |
| Work light on an arm that reaches into the trailer | Dock light | Broken arm, no light | Dock lights |
| Built-in ramp to the trailer | Dock leveler | Won't rise, won't store | Dock leveler repair |
| Loose plate moved by hand or forklift | Dock plate or board | Bent, cracked | Dock plates and boards |
Dock seals and shelters
Dock seals and shelters close the gap between the building and the trailer. A seal presses foam pads against the trailer. A shelter is a frame with fabric curtains the trailer backs into. When they tear or flatten, weather, heat, dust and pests get in, and cooled or heated air gets out.
| What you see | What a qualified provider may inspect | How to report it |
|---|---|---|
| Torn fabric on the pads or curtains | The fabric covers, wear strips | "Seal at door [number] is torn" |
| Pads crushed flat | The foam cores | "Pads are flat, gaps at the trailer" |
| Top curtain (head curtain) missing or ripped | The head curtain and its mount | "Top curtain is gone" |
| Shelter frame bent by a truck | The frame and its mounting | "Truck hit the shelter frame" |
| Gaps at the sides or top with a trailer in place | Pad sizes, mounting height | "Light and air coming around the trailer" |
| Inflatable won't fill | The blower and bags | "Inflatable seal won't puff up" |
Repair or replace? Sometimes new fabric covers or a single pad do the job. When the foam is crushed, the frame is bent, or the seal doesn't fit the trailers you get now, full replacement comes up. Ask the company which it recommends and why.
Dock bumpers
Dock bumpers are the thick blocks on the dock face that take the hit when a trailer backs in. Without them, the wall, the leveler and the trailer take the damage. Look for bumpers that are split, worn thin, torn off or hanging loose. Bumper blocks are usually replaced rather than repaired. Mention how many doors have damaged bumpers — that helps with planning.
Trailer restraints and dock locks
A trailer restraint (also called a vehicle restraint or dock lock) holds the back of the trailer at the dock while it's loaded. If it won't catch, won't let go, or the lights don't match what it's doing, stop using that door the way your facility's procedure says, and call. Never bypass or override a restraint or its lights.
Restraints have their own page, with a full table of what to report, the rules you may hear about, and what drives the price: trailer restraint and dock lock repair. Wheel chocks, whether loose or on an arm, are covered there too.
Dock lights and communication systems
Communication lights tell the driver and the dock crew when it's safe to move. Red usually means stop, and green usually means go — but check your own site's setup. An interlock is a link that makes dock equipment work in order, like not letting the leveler run until the restraint is on. Dock work lights on arms light up the inside of the trailer.
If lights are out, stuck on one color, or don't match what the restraint or door is doing, report it and follow your facility's procedure. Don't rewire, jump or bypass anything to get a door moving.
You don't need to know what failed. Describe what the lights or lock are doing.
Something failed with a trailer at the door?
If a restraint won't let go, a seal is hanging loose, or a bumper is torn off with a trailer in place, call and say so first. Keep people clear of the trailer and the dock edge. Don't pry the restraint, don't let the driver pull away until your facility's procedure says it's clear, and follow your process for taking that door out of use. The independent repair company confirms if and when it can come.
If the dock is down, say so first.
How the call works
- Call (385) 325-7138. Say which equipment and what it's doing, the door number if you know it, and the facility address.
- Company confirms the job. If the request is shared with an independent commercial repair company, it confirms availability, scope, price and its own terms.
- You decide. Nothing is approved until you agree to it.
Example of what to say: "The dock seal at door 7 at our Long Beach warehouse is torn, and daylight shows around the trailer." That's example wording — say it your way.
If you reach voicemail, leave the facility address, the door or dock number if known, what's wrong, and a callback number.

What does dock equipment repair cost?
We can't quote your 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 moves the price | Why | Ask the company |
|---|---|---|
| Trip or diagnostic charge | Many companies charge to come out and look | "Is there a trip charge, and does it go toward the repair?" |
| Seal: pads vs. whole seal | New covers cost less than a full seal | "Can you replace just the damaged pads or covers?" |
| Shelter: fabric vs. frame | A bent frame is a bigger job | "Is the frame OK?" |
| Number of bumpers | Price usually scales with count and size | "How many bumpers, and what type?" |
| Restraint type | Manual and powered restraints use different parts | "Which parts failed?" |
| Lights, controls, interlocks | Electrical faults take time to trace | "Is this a light, a sensor or the control box?" |
| Parts wait | Some brand parts must be ordered | "How long for parts, and what do we do meanwhile?" |
| After-hours work | Some companies price it differently, if they offer it | "Is after-hours priced differently?" |
A trip charge is for coming out. An estimate is a best guess. A written quote is the price for a set scope — get one before work starts.
Ask how your job would be priced when you call.
Planned dock maintenance
Seals, bumpers, restraints and lights wear out a little every day. A planned check catches torn pads, worn bumpers and restraint faults before they stop a door. Restraint service can take real time on some models because covers come off for inspection, so plan it around your receiving schedule. A qualified provider sets the checklist. Doors at the same docks are on planned door maintenance. Levelers are on the leveler page.
What's included and what isn't
Included: dock seals, dock shelters, inflatable seals and shelters, dock bumpers, trailer and vehicle restraints (dock locks), wheel chocks, dock work lights, communication lights and interlocks at commercial buildings.
Not included:
- Trailer body repair, trailer doors and trailer suspension or axle work.

Local checks before you hire
- License. Ask which California license class the company uses for the restraint and any electrical work, then check it on the CSLB license lookup.
- Workplace rules. California runs its own workplace safety program, so Cal/OSHA's Title 8 rules apply at California docks. Your safety lead knows your site's dock procedure.
- Permits for new electrical work. In the City of Los Angeles, "Electrical Permits are required for any electrical work" (LADBS). Other cities and the County have their own offices — see the service area.
The provider and the permit office confirm what your job needs.

Frequently asked questions
Can I call about a dock lock here?
Yes. Restraints and dock locks have their own page with more detail. If a lock won't release, keep people clear, follow your facility's procedure, and say so first when you call.
Can torn dock seals be patched, or do they need replacing?
Sometimes new covers or a single pad fix it. If the foam is crushed flat or the frame is bent, replacement usually comes up. The company looks and tells you.
Does OSHA require vehicle restraints?
Federal OSHA does not require a powered vehicle restraint. Many facilities use restraints or wheel chocks as part of their own dock procedure. Ask your safety lead what your site requires.
Can I call about trailer doors or trailer body damage?
No. This line is for equipment that's part of the building. Trailer doors and trailer body repair are a different trade.
How often should restraints and seals be checked?
It depends on how busy the dock is. A qualified provider can suggest a schedule. Many sites fold dock equipment into regular planned maintenance.
