Which dock equipment is this?
Around every dock door there's gear that seals the trailer, protects the building, and holds the trailer in place. "Loading dock" matters in the name. On the Mississippi, "dock seal" and "dock bumper" can mean boat docks, and those aren't covered.
| What you see | What it's called | What to mention |
|---|---|---|
| Foam pads around the door opening | Dock seal | Torn or flat pads, daylight gaps |
| Frame with side and top curtains | Dock shelter | Torn curtains, bent frame |
| Rubber or steel-faced blocks on the dock face | Dock bumpers | Worn, missing or loose |
| Hook or arm below the leveler, with signal lights | Vehicle restraint, also called a dock lock | Won't hook, or won't let go |
| Device at the trailer's wheels | Wheel-based restraint | Won't engage or release |
| Loose blocks at the wheels | Wheel chocks | Damaged or missing |
| Signal lights inside and outside the door | Communication lights | Which lights, and whether they disagree |
| Swing-arm lamp at the door | Dock light | Won't light, or arm broken |
| Control box that links the door, leveler and restraint | Controls and interlocks | Which step won't happen |
| Lift platform at the dock | Dock lift | Describe it; reviewed case by case |
Vehicle restraints: trailer restraints, truck restraints and dock locks
A vehicle restraint holds the trailer at the dock so it can't pull away or creep while a forklift works inside. "Trailer restraint," "truck restraint" and "dock lock" usually mean the same equipment. Some makers use their own brand names too.
| Name you've heard | Usually means | Note |
|---|---|---|
| Vehicle restraint | A device that holds the trailer at the dock | The general term |
| Trailer restraint | Same | Common in warehouses |
| Truck restraint | Same | Common with box trucks and straight trucks |
| Dock lock | Same, usually a hook type | Also a nickname for the whole system |
| Wheel-based restraint | Holds the trailer by a wheel instead of the rear bar | Different parts from a hook type |
| Wheel chock | A block placed at the wheel | Not a powered restraint |
What to report
Describe what you've already seen, and whether loading has stopped. Don't force a release or override anything.
| What's happening | What a qualified provider may assess | Why it matters | What to say on the call |
|---|---|---|---|
| Won't engage | The device, the trailer's fit, controls | Trailers and restraints don't all match | Which dock, and what happened |
| Won't release | The restraint, controls, interlocks | Releasing it is not a caller's job | Whether a trailer is still there |
| Inside and outside lights disagree | Sensors, wiring, controls | The lights alone don't prove the trailer is held | What each light showed |
| The door or leveler won't run because of the restraint | Controls and linked equipment | Several devices may be part of the fix | What won't happen; don't override it |
| A hit or visible damage | The device, its mount, nearby gear | May need more than an adjustment | What happened, and which dock |
ANSI MH30.3-2022 is the standard for vehicle restraining devices (ANSI). OSHA's dockboard rule calls for "measures, such as wheel chocks or sand shoes," to keep the vehicle from moving while employees are on the dockboard (29 CFR 1910.26(d)). OSHA's forklift rule calls for brakes set and wheel chocks placed while a forklift drives onto a trailer (29 CFR 1910.178(k)(1)). These two rules name measures such as wheel chocks. They don't name powered vehicle restraints. A restraint is one kind of measure, and the chock rule in 1910.178(k)(1) still applies when a forklift boards. For more, read vehicle restraints vs. wheel chocks.
If a restraint won't let a trailer go, say so first.
Dock seals and dock shelters
A dock seal presses foam pads against the back of the trailer. A dock shelter surrounds the trailer with curtains on a frame. Both keep weather out of the gap.
Report what you see: torn or flattened pads, daylight gaps around the trailer, torn side or top curtains, or a frame bent after a hit. At the Moline airport, the 1991–2020 normals average 128.7 days a year with a low at or below 32°F (NOAA). So a gap is worth mentioning when you call.
Dock bumpers
Bumpers are the blocks on the dock face that take the hit when a trailer backs in. They may be laminated rubber, molded rubber, or steel-faced. Report bumpers that are worn through, missing, or loose. Also report any damage to the wall or leveler behind them.
Bumper replacement arranged as a service is covered. Buying bumpers by themselves is a parts order and isn't. Concrete repair to the dock face is outside this scope.
Lights, controls and interlocks
Communication lights tell the driver and the forklift driver what's happening at the dock. An interlock is a control that won't let one step happen until another is done — for example, the door won't open until the restraint is set. Report which lights are on, and which step won't happen. Never override an interlock to get a trailer loaded. Report it.
Other dock equipment
Dock lifts: describe it, and it's reviewed case by case. Forklifts, conveyors and racking aren't covered. Dock plates and levelers are on the dock leveler page.
When the dock is down
Call (385) 325-7138 and say "dock down," which dock, and what the restraint or lights are doing. The independent provider confirms whether and when it can come. This page can't promise a time.
- Keep people and forklifts clear.
- Don't pull a trailer away while a restraint is holding it.
- Follow your facility's process for taking the dock out of use.
If the dock is down, say so first.

- Your request may be shared. It may go to an independent commercial dock-and-door repair company.

Example of what to say
Example wording — not a script:
"The restraint at dock 6 in our Moline plant won't release the trailer, and the outside light is still red."
Useful to have, not required: which component, the brand if a nameplate is in plain view, and how many docks need work.
If you reach voicemail, leave the facility address, the door or dock number if known, what's wrong, and a callback number.

What moves the price
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.
Ask whether you're hearing a call-out or diagnostic fee, a starting price, an estimate, a scoped fixed price, or a final written quote.
| What drives it | Why it moves the number | What to ask |
|---|---|---|
| Component type | Seals, shelters, bumpers and restraints use very different parts | Which part failed? |
| Brand and parts | Some parts are made to order | Are parts in stock? |
| Number of docks | Several docks on one visit can change the math | Can you quote all the docks together? |
| Electrical work | Restraints and lights may need wiring | Is wiring included, or a separate trade? |
| Damage behind the part | Concrete work is separate | Does the wall need another trade? |
| After-hours access | Some providers charge more outside normal hours | Is there an after-hours rate? |
Local checks
The safety agency changes at the river. Iowa OSHA runs a state plan on the Iowa side (OSHA). In Illinois, federal OSHA covers private employers (OSHA). Wiring for restraints and lights falls under Iowa's state electrical licensing, or under city electrical registration in Illinois. The provider decides who does the wiring. Contractor rules differ too. See before you hire on either side of the river.
Where dock equipment calls are taken

Questions about dock equipment
How do dock locks work?
Most hook onto the trailer's rear bar. Others hold a wheel. Lights inside and outside show the status. The lights alone don't prove the trailer is held.
What's the difference between a dock seal and a dock shelter?
A seal presses foam pads against the trailer. A shelter surrounds it with curtains on a frame.
Does OSHA require a vehicle restraint?
The two OSHA rules on this page don't name vehicle restraints. They call for measures such as wheel chocks. A restraint is one kind of measure.
Can I call about replacing just the bumpers?
Yes, as a service. Buying bumpers by themselves is a parts order, and that isn't covered.
The restraint won't let the trailer go. What now?
Don't force it or pull the trailer away. Call and say so first. The provider decides how to release it safely.
Are dock plates covered here?
They're on the dock leveler page, plates section.
