What a trailer restraint actually does
A vehicle restraint is a powered or manual device at the dock that engages the trailer — usually its rear impact guard, sometimes a wheel — to hold it against pull-away or creep while a forklift is working inside it. Most people at a dock call it a dock lock. It usually comes with a light package that communicates the status to the driver outside and the dock worker inside.
It is not the same thing as a wheel chock, and it does not automatically replace one. More on that below, because it is the part people get wrong.
| What you can see at the dock face | What it is called | How you'd know it failed | What to mention on the call |
|---|---|---|---|
| A hook or barrier that rises to catch the trailer's rear bar | RIG restraint — it engages the rear impact guard. Most people say dock lock | It won't rise, won't catch, or won't let go | Position number, and whether a trailer is held |
| A device that clamps or blocks a wheel | Wheel restraint | It won't deploy or won't retract | Position number, trailer present or not |
| An arm you swing or crank by hand | Manually operated restraint | It binds, or won't stay engaged | Position number |
| Red and green lights inside and outside the bay | Communication light package | Lights stuck, or disagreeing with reality | Which light, inside or outside |
| A chock stored on a hook by the bay | Wheel chock — a separate vehicle-movement control | Cracked, missing or unsuitable for the vehicle | Position number and what is missing or damaged |
The published standard for this equipment class is a separate designation from the ones covering installed and portable leveling devices — vehicle restraining devices have their own scope and should not be lumped in with levelers (ANSI MH30.3-2022 catalogue entry, checked September 19, 2026). This identifies the equipment family; it does not establish which requirements apply to your dock.
What the rules actually say about securing a trailer
This is the part worth getting straight, because a lot of dock content gets it backwards.
The federal requirement is about the vehicle, and it sits on the employer. Before a powered industrial truck boards a highway truck, the truck's brakes have to be set and wheel chocks placed under the rear wheels to prevent it rolling. Where a semitrailer is not coupled to a tractor, fixed jacks may be necessary to support it and stop it upending (29 CFR 1910.178(k), checked September 19, 2026). Separately, before a truck crosses a dockboard, that board must be properly secured and its rated capacity not exceeded (29 CFR 1910.178(n)(11), checked September 19, 2026).
Notice what is not in there: the rule does not name a powered vehicle restraint. A restraint is a means many facilities use to address vehicle movement. But installing one does not automatically discharge every duty, and no web page can tell you that yours does.
The practical consequence is simple and it matters most on the day the restraint is out of service: the duty does not pause because the device is broken. Your facility's own procedure for that position has to cover what happens next, and that procedure belongs to you and your qualified provider, not to us.
Communication lights, controls and interlocks
The light package is the part everyone actually relies on. On the common red/green arrangement, green outside signals that the driver can move; red outside means stay put. Inside, green signals secured and red signals unsecured. The posted instructions and exact system matter — a light alone is not proof that the trailer is held. When those lights stop matching reality, the signal system everyone has been trusting quietly stops working (Rite-Hite RHR-1100 owner's manual, page 4, September 18, 2025 edition; checked September 19, 2026).
Manufacturers build these as light communication systems paired with the restraint, and controls can be arranged to interlock the restraint with the leveler and the door, so the sequence at the bay only runs in a safe order (Rite-Hite light communication system, Rite-Hite interlock controls, checked September 19, 2026). That is why one fault at an interlocked position can look like three faults — a restraint that won't confirm engagement can block the leveler and the door as designed.
What a qualified provider may inspect: the control panel, light heads and lenses, wiring and conduit at the dock face, the status signal coming from the restraint itself, and the interlock logic between devices.
What to report: which position, which light, and whether the restraint itself still physically moves.
One thing to be clear about: do not bypass a restraint, an interlock, or a light system to keep a bay running. If a position's safety devices are out, fall back to the procedure your facility already has for that, and keep the position out of use until a provider has looked at it. We are not going to publish a workaround, and you should be wary of anyone who does.
What restraint symptoms should you report?
Report whether it will not engage, will not release, or shows a light that does not match the bay's condition. Say whether a trailer is currently held and which dock position is affected.
| What you see or hear | What a qualified provider may inspect | Why it matters | How to report it |
|---|---|---|---|
| It locks but won't unlock | Drive, hook or barrier, controls, interlock logic | This one strands a driver and a trailer at a live position | "It engaged and won't release" |
| Won't engage at all | Drive, engagement mechanism, controls, trailer fit | Not every trailer presents the same bar to catch | "The lock won't grab" |
| Engages and immediately releases | Drive, sensing, controls, hook condition | Intermittent engagement is worse than none, because people trust it | "It catches then lets go" |
| Inside light stays red although the restraint appears engaged | Controls, light heads, wiring, restraint status signal | Appearance alone does not prove the trailer is secured | "The restraint looks engaged, inside light's still red" |
| Inside light stays green with nothing at the position | Same as above | A false green is the dangerous direction of this fault | "Green light, empty bay" |
| Restraint won't retract, trailer can't leave | Drive, controls, mechanical binding | A captive trailer is a scheduling problem and a driver problem | "It won't let the trailer go" |
| Restraint physically bent after a strike | Device structure, mounting, dock face | Bent mounting is a structural question, not just a device question | "A trailer hit it, it's bent" |
| Control panel dead | Power, panel, wiring, interlocks | On an interlocked dock this can block the door and leveler too | "The panel is dead" |
| Restraint engages but nobody can tell whether it caught | Status signalling, lights, controls | This is exactly what the light package exists to prevent | "We can't tell if it's holding" |
Nobody at your facility should reach into a restraint, work under a raised leveler, or stand between a trailer and a dock face to look at one.
Nameplates you may find
Restraints usually carry the name of a dock equipment manufacturer. Names you may see include Rite-Hite, Blue Giant, Kelley and Serco, who each publish restraint families alongside their levelers and seals (Rite-Hite, Blue Giant, Kelley, Serco, checked September 19, 2026). This is here so you can read a label. It is not a claim that anyone is a dealer for them, stocks their parts locally, or services all of them.
Yard vernacular mangles product names constantly, and that is fine. A rough name is more useful on a call than no name, and no name at all is perfectly workable.
What we cover — and what we don't
Covered: vehicle and trailer restraints, dock locks, their controls, interlocks and communication packages at commercial loading docks.
Not covered:
- Dock levelers — their own page.
- Seals, shelters, bumpers and dock lights — dock equipment repair.
- Doors — overhead, roll-up, high-speed, fire-rated.
- Anything on the trailer itself, including the trailer's own rear impact guard.
- Yard truck and trailer maintenance.
- Boat docks and marine structures.
- Structural concrete at the dock face.
- Parts-only requests.
What happens when you call (385) 325-7138?
1. You describe the facility and the dock position. No model number, photo, measurement or diagnosis needed.
2. The request may be shared with an independent commercial dock-and-door repair company.
3. That company confirms the address, scope, availability, price, scheduling and its own contract, work and warranty terms with you directly.
If you reach voicemail, leave the facility address, the door or dock number if known, what's wrong, and a callback number.
Ask for the company's name, experience with your restraint and interlock system, and written scope before authorizing work.
Example wording, not a real job:
"The dock lock on position 9 at our building in Pooler won't release and the driver is waiting — I can give you the address."
What's useful to have on the call — if you already have it
Optional.
- Dock position number.
- Whether a trailer is currently held there.
- Whether the lights still change at all.
- Whether the restraint moves at all.
- Whether this is a first failure or a recurring one at that position.
- Whether the dock is interlocked, so the door and leveler are affected too.
- Access, hours or credential constraints at your site.
What changes the price on trailer restraint repair
We can't quote a restraint from a web page. The price depends on the device, the fault, parts, and access. Here's what to ask before you authorize work.
Ask which sort of number you have: a call-out or diagnostic charge, a "starting at" figure, a scoped fixed price, an estimate, or a committed quote. Then ask what is included — parts, labor, travel, controls, and any testing after the repair.
The drivers:
- Restraint type — RIG or wheel, powered or manual.
- Where the fault is: drive, control panel, light package, interlock wiring, or the structure the device is mounted to.
- Impact damage to the device or its mounting.
- Parts availability on an older unit.
- Whether a retrofit is being considered rather than a repair.
- Whether a trailer is currently held at the position — that changes the sequence of the visit, and sometimes the urgency of it.
- Access and credential requirements at the site.
Repair or retrofit?
The honest factors: age and parts availability for the existing device; whether the dock face and approach still suit it; whether your trailer mix has changed since it was installed; and whether the light package would need replacing anyway. A restraint that fails to engage on a growing share of trailers calls for a check of trailer compatibility as well as the device.
Local rules that touch restraint work in Savannah
None of this decides whether a rule applies to your dock. The provider and the issuing office confirm that.
Licensing. Georgia's state licensing board lists loading dock equipment among traditional specialty contractors, whose work inside that specialty does not require a residential or general contractor license — while expressly keeping separately regulated trades in force (Georgia Secretary of State, list revised 03/06/20, checked September 19, 2026). For powered restraints, ask which electrical or low-voltage contractor credential covers the proposed power, sensing and interlock wiring work. Georgia licenses electrical contractors and low-voltage contractors; the equipment name alone does not decide the required scope. Look the name up at the state license search.
Permits. Unincorporated Chatham County names electrical work among permit-required work unless waived by the authority (Chatham County Building Safety, checked September 19, 2026). A control panel replacement and a mechanical adjustment are not the same scope.
Port access. Georgia Ports Authority requires regular marine-terminal users to hold a Transportation Worker Identification Credential and a GPA-issued badge, with company registration before employee badge requests. Its credentialing page also describes visitor passes for occasional legitimate access (Georgia Ports Authority credentialing, checked September 19, 2026). For a terminal position, confirm the technician's approved access or visitor/escort arrangements with GPA before the visit.

Restraint and dock lock questions
The restraint won't release and a driver is waiting. What should we do right now?
Keep people out from between the trailer and the dock face, and do not try to force or defeat the device. Use your facility's existing procedure for a position that is out of service, and say on the call that a trailer is currently held — that is the detail that changes how the request gets handled.
Does OSHA require a vehicle restraint?
Not by name. The federal requirement addresses the vehicle: brakes set and wheel chocks under the rear wheels before a powered industrial truck boards, and fixed jacks where an uncoupled semitrailer needs support. A restraint is a means many facilities use to address that, and it is a good one — but whether your arrangement satisfies the duty is a question for your safety lead and your provider, not for a web page.
Can a restraint be added to a dock position that doesn't have one?
Often, and it is a real project rather than a part swap. It involves the dock face and its structure, the approach and trailer mix, power and controls, and usually the light package. Describe the position and what you are trying to solve, and a provider can scope it.
The lights are stuck but the restraint seems to work. Does that still need fixing?
Yes. The lights are how the driver and the dock worker agree on what is happening. A restraint that is holding, with a light saying otherwise, is a system nobody can trust — and on an interlocked dock a bad status signal can block the leveler and door as well.
Call about the restraint that's down
Give us the facility and the dock position, and say whether a trailer is held.
