Which dock equipment needs work?
Name the part if you know it. If you don't, say where it is and what it does. This table covers the gear around a loading dock opening.
| Equipment | What it looks like | What it does | What to report | Section |
|---|---|---|---|---|
| Dock seal | Foam pads around the opening | Presses against the trailer to close the gaps | Torn, crushed, missing | Seals and shelters |
| Dock shelter | Fabric curtains on a frame | Covers the gap around trailers of different sizes | Torn curtains, bent frame | Seals and shelters |
| Dock bumper | Rubber blocks on the dock wall | Takes the hit when a trailer backs in | Worn down, split, missing | Bumpers |
| Dock light | A light on a swing arm by the door | Lights the inside of the trailer | Broken arm, no light | Lights and chocks |
| Wheel chock | A wedge at the trailer's tire | Helps keep the trailer from rolling | Missing, damaged | Lights and chocks |
| Trailer restraint (dock lock) | A dock-mounted hook for a trailer's rear impact guard, or a wheel restraint near the tire | Helps secure the trailer at the dock | Won't engage or release | Trailer restraints |
| Signal lights and interlocks | Status lights inside and out, sometimes tied to the door or leveler | Communicate status under the facility's procedure | Stuck on one color | Trailer restraints |
Dock equipment nameplates you may see include Rite-Hite, Kelley, Serco and Blue Giant. A name helps identify equipment. It doesn't mean the provider is an authorized dealer.
Dock seals and shelters
Dock seals and shelters close the gap between the building and a parked trailer. Torn or crushed ones let outside air, heat and weather in. At a cold-storage dock, that gap works against the cooled space.
Seal or shelter: which do you have?
- A seal is thick foam pads that the trailer presses into.
- A shelter is a frame with fabric curtains that wrap around the trailer without being crushed.
Repair or replace?
- Torn fabric or worn wear-strips can often be replaced by themselves.
- Pads that are crushed flat, or a bent shelter frame, may need more.
- If your trailers have changed size, the old seal may not fit anymore.
The provider looks and tells you what makes sense.
These are loading-dock shelters, not the marina shelters you'll find around San Diego Bay.
Dock bumpers
Bumpers take the hit every time a trailer backs in. When they're worn down or missing, the trailer hits the dock wall and the leveler instead. Report worn or missing bumpers early, before the dock itself gets damaged. Broken concrete behind a bumper is concrete work and isn't covered here.
Dock lights and wheel chocks
Report a broken light arm or a light that's out. Report missing or damaged wheel chocks too. Your facility sets its loading-dock procedure. California's Cal/OSHA §3336 requires employers to establish and enforce a system that prevents trucks or trailers from pulling away before loading or unloading is complete.
Trailer restraints and dock locks
A trailer restraint, often called a dock lock or vehicle restraint, helps secure the trailer at the dock. Its lights communicate status under the installed system and facility procedure. If it won't engage, won't release, or the lights are stuck, stop using that dock and call (385) 325-7138.
Types you might have
- Hook-style restraints engage the trailer's rear impact guard when compatible.
- Wheel-style restraints hold a trailer tire.
- Some are manual, and some are powered with push buttons.
You don't need to know which one to call.
What the lights and signals are telling you
| What you see | What it may mean (the provider confirms) | What to do now | What to report |
|---|---|---|---|
| A status light does not change as expected | Restraint, sensor, lamp or control fault | Follow your facility's process. Do not rely on the light alone to start loading. | Light behavior and dock number |
| Light indicates a secured trailer when none is present | A status or control fault | Take the dock out of use until checked | Light indication and dock number |
| Hook won't rise or can't reach the trailer | A mechanical or power fault, or the trailer's bumper bar is at an odd height | Don't force it | Won't reach, and the dock number |
| It won't let go of the trailer | A mechanical or control fault | Let the driver know the dock isn't cleared. Follow your facility's process. | Won't release, and the dock number |
| The leveler won't run until the restraint catches | The interlock may be doing its job, or it may be faulty | Don't bypass it | Interlock is stopping the leveler |
Never bypass a restraint or an interlock. If the driver and the dock crew can't trust the lights, that dock shouldn't be used until it's checked.
Rules to know
California workplaces follow Cal/OSHA Title 8, which has a section titled Loading Dock Operations (§3336). Your safety lead decides your facility's restraint and chocking practice. A provider can tell you how your restraint is meant to work with your leveler and door.
If the restraint won't catch or let go, say so first.
What happens when you call?
You call, say which dock and what's wrong, and your request may be shared with an independent commercial repair company. That company confirms whether it can take the job, when, and the price. Uptime doesn't do repairs.
- Call and describe the equipment and the problem.
- Your request may be shared with an independent commercial dock-and-door repair company.

Example of what to say: "The dock lock at door 8 won't release and the light's stuck red, at our warehouse in San Diego."
If you reach voicemail, leave the facility address, the door or dock number if known, what's wrong, and a callback number.
You can call without a brand or model. The dock number and what you see are enough. See how requests work.
Call and describe the dock.
What affects the cost of dock equipment repair?
We can't price dock equipment work from a web page. It depends on what's damaged, the make, parts, and whether controls or wiring are involved. Here's what to ask before you authorize work.
| What drives the price | Why | What to ask |
|---|---|---|
| Equipment type | Seals, bumpers and restraints are very different jobs | "What exactly needs work?" |
| Pad, curtain or bumper size | Bigger parts cost more | "Can you replace just the torn part?" |
| Restraint type and controls | Powered restraints have motors, sensors and lights | "Is it mechanical, electrical, or both?" |
| Wiring and interlocks | Wiring can need an electrician | "Does this need C-10 electrical work?" |
| Number of docks | Several docks at once can change the visit | "Can you look at all of them on one visit?" |
| Access | Trailers at the dock, busy shifts | "Do I need to close the dock while you work?" |
Ask whether a price is a trip fee, an estimate, or a final quote. Get the final one in writing.
Call to describe the problem. The provider prices the actual job.
License checks
Dock equipment can mix mechanical work with wiring. In California, electrical wiring falls under the CSLB's C-10 class. Ask which license class covers your job, and look the number up yourself.
| Check | Where |
|---|---|
| C-10 electrical | CSLB C-10 |
| Leveler and dock machinery (D-21) | CSLB D-21 |
| License lookup | CSLB Check A License |
We checked these on September 24, 2026. The provider and the issuing office confirm what your job needs.

Questions about dock equipment
Is a "vehicle restraint" the same as a dock lock? Yes, at a loading dock. Both names mean the device that holds a trailer at the dock. Truck restraint and trailer restraint mean the same thing.
Can torn dock seal pads be replaced without replacing the whole seal? Often. Torn covers and wear-strips can sometimes be swapped on their own. The provider looks and tells you.
Why won't my dock leveler work until the restraint catches? Many docks tie the leveler to the restraint on purpose, so the leveler can't be used until the trailer is held. If it stays locked out after the restraint catches, report it. Don't bypass it.
Can I call about boat docks or marina shelters? No. This line is only for loading docks at commercial buildings.
