What kind of restraint is at your dock?
A trailer restraint, also called a vehicle restraint, truck restraint or dock lock, holds a trailer at the dock so it can't pull away or creep while a forklift is inside. Most catch the trailer's rear bumper bar (its rear impact guard) or hold a wheel. They can be manual or powered, and most powered ones have red and green lights inside and outside. A loose wheel chock is separate equipment.
| Type | How it holds the trailer | What you'll notice | Where it's covered |
|---|---|---|---|
| Hook-type restraint | A hook or bar rises to catch the trailer's rear impact guard | A hook or bar under the dock face, with a light set | This page |
| Wheel-based restraint | Holds one of the trailer's wheels | A unit on the drive at the wheel position | This page |
| Manual restraint | Worked by hand or by a lever | No motor; may still have lights | This page |
| Communication lights and interlocks | Tell the driver and the forklift operator who may move; may link to the leveler or door | Red and green lights inside and outside | Signals |
| Wheel chocks | Wedges placed at the wheels | Loose chocks on a chain or hanger | Dock equipment |
Restraints have their own industry standard: ANSI MH30.3-2022, "Performance and Testing of Vehicle Restraining Devices" (ANSI). That's a catalog title; the standard itself is a performance and testing document, not a law.
Names you may see
Blue Giant lists hydraulic and mechanical vehicle restraints on its own site (Blue Giant). Kelley, Serco, Nordock and Pioneer also make vehicle restraints (4Front brands), and Rite-Hite publishes a restraint service page (Rite-Hite). These are examples of makers, not a list of what's installed in Syracuse, not endorsements, and not a sign that any repair company is authorized by them.
What should you report about the restraint and its lights?
Describe what the restraint is doing and what the lights show as two separate things. A light is not proof that a trailer is held, or that it's free to leave. If they don't match, take that dock out of use under your facility's process and call.
| What you see | What a qualified provider may inspect | Why it matters | How to say it on the call |
|---|---|---|---|
| Won't engage the trailer | Hook or arm, drive, sensors, where the trailer's guard sits | The trailer can move | won't engage |
| Engaged, but the lights don't change | Light circuit, sensors, controls | Drivers and forklift operators go by the lights | engaged; lights not changing |
| Won't release, and a driver is waiting | Drive, controls, arm | The trailer is stuck at the dock | won't release; driver waiting |
| An alarm keeps sounding | Sensors, controls | Mixed signals at the dock | alarm won't stop |
| Arm or hook bent after a trailer pulled out | Structure, mounting | It may not hold the next trailer | bent after a trailer pulled out |
| Control panel dark | Power, controls | No restraint and no lights | control panel dark |
| The leveler or door also stopped working | Interlocks between the restraint, leveler and door | A fault in one can stop the others | leveler or door stopped too |
| Can't engage because the trailer's guard is missing or damaged | The trailer's rear guard and the restraint's reach | Your facility's backup procedure applies | trailer guard missing or damaged |
Some docks link the restraint to the leveler or door so one won't run until the other is in position. That link is a safety feature. Troubleshooting it is work for a provider. Nobody should bypass it, and this page gives no way to.
Found it? Describe the restraint and the lights, and say first if a trailer is stuck.
If a restraint won't release and the driver is waiting
Don't force the arm, pull the trailer against it, or override the controls. Keep the dock out of use, tell the driver what's happening, and call (385) 325-7138. Say first that the restraint won't release and a driver is waiting. The provider confirms when it can come.
What OSHA says, and what it doesn't
Trailer movement at the dock is part of the facility's own safety responsibilities. OSHA's rules name chocks or blocks. None of the OSHA rules we read requires a powered restraint; a restraint is one way to keep the trailer from moving.
- 29 CFR 1910.26(d): "Measures, such as wheel chocks or sand shoes, are used to prevent the transport vehicle… from moving while employees are on the dockboard."
- 29 CFR 1910.178(k)(1): the brakes of highway trucks are set and wheel chocks placed under the rear wheels when powered industrial trucks board them.
- 29 CFR 1910.178(m)(7): brakes are set and wheel blocks are in place to keep trucks, trailers or railroad cars from moving during loading or unloading.
How restraints and chocks are used together at your dock is decided by your facility's procedure and the restraint maker's instructions. More background is on our vehicle restraints vs. wheel chocks research page.
What's included, and what isn't
Included: hook-type, wheel-based and manual restraints at building loading docks, plus their lights, controls and the links to the leveler or door. That covers warehouses, distribution centers, manufacturing plants and food and cold-storage docks. One dock counts.
Not included: truck and trailer repairs, trailer cargo doors, locksmith "dock locks," concrete and mounting walls (a provider can tell you when that's the problem), and parts-only orders. Plain wheel chocks and dock work lights are on the dock equipment page. Leveler faults are on the leveler page.
For how Uptime handles loading dock requests nationally, see loading dock repair.
If your restraint fits, describe it and the dock.
What happens when you call (385) 325-7138
Start with the address, the dock, and whether the problem is grabbing, letting go, or the lights. Your request may be shared with an independent company, which confirms the work, availability, price and schedule.
- You call and describe it. Which dock, what the restraint is doing, what the lights show, and whether a trailer is there.
- The details may be shared. Your request may be shared with an independent commercial dock-and-door repair company.
- The provider confirms. That company confirms availability, scope, pricing and its service terms with you directly. Nothing is booked until it does.
For example, you might say: "The dock lock won't release at our warehouse in Syracuse and a trailer is still at that door, 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.
Uptime Dock & Door is an independent commercial service-request website for loading-dock and commercial door repair, not the repair company. Read how Uptime works and what Uptime is and isn't.
If a trailer is involved, say so first.
Useful on the call, but not required
- The dock number.
- What the restraint is doing, and what the lights show.
- Whether a trailer is there, and whether a driver is waiting.
- Whether the leveler or door at that dock also stopped.
- The restraint's maker, if you already know it.
- Any earlier hit or service record.
- Access notes.
Don't go under the dock, near the restraint, or behind the trailer to look.
What drives the price?
We can't quote your restraint repair from a web page. The price depends on the restraint, the fault, parts, and access. Here's what to ask before you authorize work.
| What moves the price | Why | What to ask |
|---|---|---|
| Trip or diagnostic charge | It may be billed separately | "Is there a trip charge, and does it count toward the repair?" |
| The holding mechanism | Hook, arm and drive parts differ by make | "Which parts failed, and why?" |
| Lights, controls and interlocks | Wiring and linked equipment | "Is the light and interlock work included?" |
| Electrical work | May need a licensed electrician and an inspection | "Whose license covers the wiring?" |
| Mounting damage | Bent mounts or wall damage may be separate work | "Is mounting or wall repair included?" |
| Replacement | A new restraint has to suit your trailers and your dock | "Does the replacement fit the trailers we get?" |
| Paperwork | Findings and the work done | "What will you give us in writing?" |
| After-hours work | Only if the provider offers it | "Do you work after hours, and how is that priced?" |
Repair or replace depends on the restraint's condition, whether parts are available, and whether it suits the trailers you actually get. There's no honest age rule. Ask for both options in writing.
Ask for the restraint and light work to be listed separately on the first call.
Restraint maintenance
A useful maintenance proposal names each restraint, its lights and its linked controls, and says what gets checked, following the maker's instructions. It also says what you get in writing after each visit, and how repairs found during a visit are priced and approved. There's no single legal schedule for every restraint; ask the provider to base it on the maker's guidance and how hard the dock works.
Licenses and permits
- No state license. New York State doesn't license this trade (NY Department of State).
- Wiring follows the municipality. Powered restraints and lights have wiring. In the Town of Clay, electrical inspections are done by agencies the Town Board designates (Clay ch. 80). In DeWitt, an inspection application goes to an approved agency before work starts (DeWitt). In the City of Syracuse, trade permit applications need a professional license number (Syracuse portal).
- Workplace safety. Private employers fall under federal OSHA; PESH covers public employers (OSHA New York State Plan).

Questions about trailer restraints in Syracuse
Is a green light proof the trailer is held?
No. A light alone doesn't prove the restraint is holding the trailer. If the lights and the restraint don't match, take the dock out of use under your facility's process and call.
Can I override a restraint that won't let go?
This page gives no override or release steps. Keep people clear, follow your facility's process, and say a trailer is stuck when you call.
Does a dock lock work with every trailer?
Not always. Some trailers have damaged or missing rear guards, and restraint designs differ. Ask the provider to confirm fit using the maker's information.
Do we still need wheel chocks if we have a restraint?
OSHA's rules name chocks or blocks, and none we read requires a powered restraint. How the two are used together is up to your facility's procedure and the restraint maker's instructions.
Does restraint repair include the lights and interlocks?
Only if the agreed scope says so. Ask which parts and linked equipment are included.
