Which restraint is at your dock?
A vehicle restraint — also called a trailer restraint or dock lock — is a dock-face or ground-mounted device designed to restrain a vehicle at the loading bay. It is not the same thing as a wheel chock, and it is not part of the leveler.
| Type | How it holds the trailer | What you'll see at the bay | Components a provider may assess |
|---|---|---|---|
| Rotating-hook restraint | A hook rotates up over the trailer's rear impact guard | A steel arm and hook on the dock face | Hook, drive, hydraulics, controls |
| Wheel-based restraint | A barrier or arm engages the rear tire | A unit in the drive approach, not on the face | Track, drive, debris, ice |
| Vertical-barrier restraint | A barrier engages the rear impact guard on the applicable model | A dock-face/ground-stored mechanism | Drive, barrier, mounting, controls |
| Manually operated restraint | The model may engage the rear impact guard rather than a tire | Existing equipment record identifies the model | Linkage, damage, sensor and communication equipment where fitted |
| Restraint with communication lights | Restraint tied to red/green lights inside and out | Light heads at the door and outside | Lights, controller, wiring, interlock |
Rite-Hite and Kelley are manufacturer identification examples, not Uptime affiliations. Report a make or model from existing records or a safely visible label; do not approach the trailer or mechanism to find one.
What is the restraint doing?
A restraint fault is reported, not worked around. Nobody goes between the trailer and the dock face. Nobody forces the mechanism. The bay comes out of use through your facility's established process until it has been inspected. Do not bypass an interlock or attempt a manual release.
| Symptom | What a provider may inspect | Why it matters | What to report |
|---|---|---|---|
| Won't engage on the trailer | Hook or barrier, drive, guard height, controls | The trailer is not secured | That it will not catch, and which bay |
| Engages then releases | Drive, hydraulics, controls, wear | Unexpected release defeats the intended restraint | That it lets go |
| Won't release, trailer is held | Drive, mechanical bind, controls, power | A driver cannot leave your dock | Say this first |
| Lights show the wrong state | Controller, wiring, light heads | The lights are the signal to the driver | What each light shows |
| Lights behave differently from the documented sequence | Controller, signals and connected equipment | Opposite inside/outside colors can be normal; color alone is not a diagnosis | Both indications, only if already observed safely |
| Control station unresponsive | Station, wiring, power | Electrical scope is separate work | Which station was affected, if already known |
| Restraint damaged by an impact | Unit, mounting, dock face | Mounting damage may be structural | What hit it |
Communication lights, controls and interlocks
Inside and outside lights can intentionally show opposite colors. For example, Rite-Hite describes a sequence in which the inside light changes to green while the outside light changes to red. Different colors alone do not prove a fault or give permission to load or move a vehicle.
Report a known fault indication, a failed light, or behavior that differs from the installed system's documented sequence. The provider must assess the actual restraint, communication package and connected controls; do not use a generic color rule to override your facility's procedure.
Some installations interlock the restraint with the dock door or the leveler, so that one will not operate unless the other is in a particular state. If your door or leveler also stopped working at the same bay, mention both. That does not identify which component failed.
The dock leveler page covers the installed deck and lip. Dock equipment repair covers separate loading-bay accessories; a task light that illuminates a trailer is not the same as a restraint-status light.
Why a restraint failure stops the bay, not just the trailer
OSHA 29 CFR 1910.26(d) requires measures to prevent transport vehicles from moving while employees are on dockboards. A failed restraint therefore affects the loading arrangement, not just whether the driver can leave.
OSHA directive STD 01-11-007 addresses positive mechanical restraint alternatives under its stated conditions, including effective prevention of movement, manufacturer-compliant installation, maintenance and use, and immediate removal of damaged equipment from service. It is not a do-it-yourself substitution procedure or proof that a particular loading arrangement complies.
Keep people clear and use your facility's established out-of-use procedure when the restraint has failed. MHI's ANSI MH30.3-2022 summary identifies the vehicle-restraint standard's scope; the operating instructions for the actual installed system still matter.
What to say when you call
Facility address, bay number, and what the restraint is doing.
Example wording — an example, not a real job: "The restraint at bay 9 won't release and the driver can't pull out — we're in Newark."
If you reach voicemail, leave the facility address, the door or dock number if known, what's wrong, and a callback number.
Optional, never required: restraint make from a record you already have, whether the lights are working, and whether the door or leveler at that bay is also affected.
What happens after you call
- You describe the facility, the bay and what the restraint is doing.
- The request may be shared with an independent commercial dock-and-door repair company.
- That company confirms address, coverage, scope, timing and charges before anything is scheduled.
What this covers and what it doesn't
Covered. Vehicle and trailer restraints, dock locks, their drives, hydraulics, mounting, controls, communication light packages and interlocks at commercial loading docks.
Not covered. Anything on the trailer itself — that is the carrier's equipment. Residential garages. Boat docks and lifts. Truck and trailer cargo doors. Pedestrian storefront and walk-through doors. Parts-only orders. Structural concrete and dock-face repair.
What affects the price
We can't quote your restraint repair from a web page. The price depends on the unit, the fault, parts, and access. Here's what to ask before you authorize work.
| Cost driver | Why it changes the job | What to ask |
|---|---|---|
| Restraint type | Restraint type changes the mechanism and compatible parts | Which unit is this, and is the part available? |
| Where the fault is | Mechanical, hydraulic and control scopes differ | Is control and wiring work included? |
| Light package and interlock | Communications and interlocks may need a distinct assessment | Are the lights and interlock in the quote? |
| Mounting and impact damage | Damage can reach the dock face | Is the dock face in scope, or a separate trade? |
| Access and bay downtime | Safe access and the required bay interruption must be agreed | How long is the bay out? |
| Diagnostic and travel | Someone has to look first | What is charged before approval? |
Repair or replace the restraint?
Ask which damage, compatibility issue or unavailable part supports the recommendation. A damaged hook, mounting, control system or rear impact guard must not be treated as interchangeable problems. The carrier is responsible for its vehicle equipment; structural dock-face work is outside this service scope.
A proposal should distinguish restraint repair, replacement, associated communication/interlock work and the checks needed before the facility returns the bay to use. Do not assume that replacing a light repairs the restraint, or that a new restraint automatically works with an existing controller.
Ask what the repair scope actually includes.
Which Newark rules belong in restraint work?
The work scope decides the approval question, not the label “dock lock repair.” Describe whether the proposal repairs existing equipment, changes mounting, replaces the unit or adds wiring.
| Work in the proposal | Official route | Question to resolve |
|---|---|---|
| Existing equipment repair or replacement | NJ ordinary-maintenance rule and Newark Building Division | Does the exact scope qualify, or does it include work needing approval? |
| Power, signals or interlock wiring | NJ electrical board and license lookup | Who is responsible for regulated electrical work and its permits? |
| Damaged mounting or dock face | Construction official and the responsible structural trade | Is there building damage outside the restraint scope? |
Call about the problem before doing any new inspection or permit research. The Newark local rulebook explains the separate company, scope and approval checks.

Questions about restraint repair
Can we load with the restraint out of service? Do not keep loading through a bay that relies on a failed restraint. Follow your facility's established out-of-use procedure and have the failed equipment assessed. A web page cannot approve an alternative vehicle-securing arrangement.
The lights disagree. Which one is right? Different colors alone do not tell you that either light is wrong. Inside and outside signals can intentionally differ; follow the installed system's documented sequence and your facility's procedure. Report any known fault or unexpected behavior without approaching the mechanism or testing it.
Is a wheel chock an acceptable substitute? Do not improvise a substitute for a failed restraint from a web-page answer. The employer's established loading procedure and the applicable rules must address the actual vehicle, equipment and conditions. Report the failed restraint and keep the affected bay out of use through that procedure.
The restraint is holding a trailer. What now? Say that first when you call. Keep people out from between the trailer and the dock, do not attempt a release, and take the position out of use through your normal process.
