What this page covers
The loading bay is more than a door and a leveler. This page owns the equipment around them: the seals and shelters that close the gap to the trailer, the bumpers that take the impact, portable plates and boards, and the lights, chocks and barriers that manage traffic at the bay.
If the failure is the door, go to overhead or roll-up. If it is the installed deck and lip that bridges to the trailer, that is dock leveler repair. If it is the hook or arm holding the trailer, that is trailer restraint repair. The accessory families below are covered here.
Plates and boards
A portable dock plate or dock board — also called a bridge plate — is a loose metal bridge you set down and lift away. It is not the installed leveler built into your dock, even though people call both "the dock plate." The distinction matters because portable devices carry their own rating and their own rules.
Plate or board? The industry treats them as different things. In the ANSI MH30.2-2015 preview, a dockplate carries lighter loads through the plate itself; a dockboard adds structural side members that support heavier loads and act as curbs. The current catalogue lists ANSI MH30.2-2022, Design, Testing, and Utilization of Portable Dock Leveling Devices (MHI standards catalogue). The device's own rating and instructions govern its use.
The thing to be careful about: a damaged portable device is not automatically repairable. Do not assume a bent, cracked or deformed plate or board can be welded, straightened, or put back into service. Its manufacturer's rating and instructions, its actual condition, and the traffic you intend to put across it govern whether it can be used at all. Appearance is not a rating. Name is not a rating. And a device sized for hand trucks does not become a forklift bridge because the leveler is down.
Federal rules that shape how these are used. OSHA's dockboard standard requires that dockboards be capable of supporting the maximum intended load; that portable dockboards be secured by anchoring or by equipment that prevents them moving out of a safe position, or, where securing is not feasible, that there be sufficient contact to prevent movement; that measures such as wheel chocks or sand shoes prevent the transport vehicle from moving while employees are on the dockboard; and that portable dockboards have handholds or other means for safe handling (29 CFR 1910.26). Dockboards put into initial service on or after January 17, 2017 must also be designed and maintained to prevent transfer vehicles from running off the edge, unless the employer can demonstrate no such hazard exists. Separately, powered industrial trucks may not be driven over a dockboard or bridgeplate until it is "properly secured" (1910.178(n)(11)).
Those are employer duties about how the device is used, not repair instructions — and they are a good reason to get a damaged portable device assessed rather than kept in the rotation.
| What the caller calls it | What it usually is | What the provider needs to establish | Where it is handled |
|---|---|---|---|
| "Dock plate" | Could be a portable bridge or, colloquially, the installed leveler | Whether it is loose or built into the dock | Describe it on the call |
| Portable dock plate | Loose bridge, commonly for hand trucks and pallet jacks | Model-specific capacity and vehicle restrictions, condition, securing method | This section |
| Portable dock board | Loose bridge with curbs, commonly rated for powered traffic | Exact rating, traffic, height difference, structural condition | This section |
| Pit leveler | Installed hinged deck and lip | Mechanism, symptom, other affected bays | Dock leveler repair |
| Edge-of-dock leveler | Installed unit bolted to the dock face | Model or geometry, fault | Dock leveler repair |
| Dock lift | Platform raising and lowering between elevations | Lift identity; standard leveler service does not apply | Dock lifts |
If you need a replacement: say on the call that the question is portable device selection, rating and replacement rather than repair. The provider needs to match the device to your traffic and bay.
Dock seals and shelters
A dock seal is the set of compressible pads — usually foam covered in fabric — mounted around the door opening that the trailer backs into and squeezes. A dock shelter is the alternative approach: a fabric or rigid frame hood with curtains that drapes over the back of the trailer rather than being crushed by it. Seals suit consistent trailer sizes; shelters tolerate more variation and larger trailers.
Trailer contact, weather and wear can damage the pads, fabric or frame.
Common reports: fabric split along the seam or shredded off the face pad; foam compressed flat and no longer springing back; the head curtain torn away or hanging; daylight visible around a docked trailer; the mounting frame bent or pulled from the wall after an impact; a shelter's side curtains stripped; water tracking into the building at the top of the opening.
Why it is worth fixing rather than living with. A failed seal leaves gaps around a docked trailer while the door is open — heat out in a Pittsburgh winter, cooling out in summer, and a route in for weather, dust and pests. Rite-Hite's seal and shelter guidance identifies environmental separation and hygiene as reasons to close those gaps. For a food or pharmaceutical facility, ask which site-specific sanitation or audit requirements the replacement must support.
What a provider will want to know: whether the damage is fabric, foam, frame, or all three; whether one bay or several; the trailer mix that docks there; and whether the opening has been hit. Seal and shelter selection is genuinely dependent on trailer height and width variation, so a provider asking about your trailer mix is doing it right.
Boundary: replacing seals and shelters is dock equipment work. Repairing the wall, the dock face concrete or the structural opening behind them is not.
Dock bumpers
Dock bumpers are the rubber, laminated or steel-faced assemblies at the dock face where the trailer makes contact. Missing or worn bumpers expose the building and equipment to impact damage.
Why a missing bumper matters more than it looks. The bumper is what stands between a trailer's rear frame and your dock face, your leveler lip, and your seals. When bumpers are gone, worn thin or hanging, trailer contact can damage concrete and equipment. Lost bumper projection also changes the trailer-to-building spacing, so the provider needs to check leveler lip contact and seal compression. Rite-Hite's bumper guidance calls for the approach, dock height, trailer type and mounting face to be assessed when selecting a bumper.
Common reports: bumper split, delaminated or torn away; only the mounting bolts left; bumpers worn thin enough that the trailer touches concrete; new impact damage to the dock face or leveler lip after bumpers were lost.
What a provider will want to know: how many bays, whether the mounting points and the concrete behind them are intact, what bumper style is there now, and whether trailer contact geometry has changed. Bumper replacement is usually straightforward. What is not straightforward — and is outside this scope — is repairing the spalled or broken dock face concrete a missing bumper has been chewing on. That is structural work for a concrete trade.
Dock lights, chocks and barriers
The accessories at the bay do real work, and they fail in ways that stop loading.
Dock lights — the gooseneck or arm-mounted lamps that light the inside of a trailer. Reports: arm bent or broken after a forklift contact, head smashed, switch dead, no power at the bay.
Communication lights — the red and green light pairs inside and outside the door that tell the driver and the dock crew whose turn it is. Reports: a light dark or a displayed state that does not match what the restraint is doing. Opposite inside and outside colors can be normal; report which signal you mean. A light is a signal, not proof that a bay is safe. If the lights and the restraint disagree, treat the bay as not ready and report both behaviors. Where lights are wired into a restraint or interlock system, the fault is usually on trailer restraint repair.
Wheel chocks — OSHA's powered industrial truck standard requires brakes set and wheel blocks in place to prevent movement of trucks, trailers or railcars while loading or unloading (1910.178(m)(7)). Chocks are usually a consumable the facility replaces itself, but chock-restraint systems and chock holders mounted at the bay are equipment. Our national reference compares vehicle restraints and wheel chocks.
Barrier gates and dock guards — the folding or swinging barriers across an open dock door. Reports: bent after impact, latch broken, will not stay in position, mounting pulled loose. An open dock edge is a fall exposure. OSHA's 1910.28(b)(1) generally requires protection at unprotected edges 4 feet or more above a lower level; its loading-dock exception depends on demonstrated infeasibility, work in process, restricted access and training. The separate dockboard provision in (b)(4) does not create a general 10-foot exemption for an open dock. Your organization's safety process determines the protection required for the actual bay.
Dock lifts
A dock lift is a platform that raises and lowers loads between two elevations — typically from ground level up to dock height where there is no dock, or between a dock and a trailer of unusual height. It is not a leveler, and standard leveler service does not cover it.
If you have a lift, say "dock lift" on the call and describe what it is doing. Hydraulic lifting equipment has its own service considerations, and not every dock-and-door provider works on lifts. It is better to establish that in the first minute than after a trip charge. Do not attempt to work on, prop, or go under a lift platform.
Planned dock equipment maintenance
Seals, bumpers and accessories need a place in the dock maintenance scope. A useful provider-performed scope covers: seal and shelter condition by bay, including fabric, foam and frame; bumper thickness, mounting and dock-face condition; dock light arms, heads and switches; communication light function and agreement; barrier condition and latching; and a written per-bay record of findings.
Two questions worth asking: what frequency is recommended, and on what basis — the equipment manual, trailer throughput and weather exposure all matter; and what report you receive afterward. A per-bay list of findings and proposed actions is useful. A signature saying someone visited is not.
Door-side planned service is on commercial garage door maintenance. Leveler service is on dock leveler repair.
What to say when you call
Location, bay, what is damaged.
Example wording: "Both dock bumpers came off bay 4 at our Pittsburgh warehouse and the seal is torn, and I can give you the address." That is an example of how to open the call, not a real job or a script.
How the call works:
- You call (385) 325-7138 and describe the facility location and the observable problem.
- Your request may be shared with an independent commercial dock-and-door repair company.
- That company confirms whether it can accept the work, whether the equipment and address fit what it does, and its availability, pricing, scheduling and service terms.
If you reach voicemail, leave the facility address, the door or dock number if known, what's wrong, and a callback number.
Optional, if you already have it: how many bays are affected; whether seals or shelters are installed; the bumper style; the trailer mix that docks there; and whether the opening has been struck. None of it is required.
What this service covers — and what it doesn't
Commercial building-mounted doors and loading-dock equipment only. This call path is not for residential garages, boat docks or boat lifts, truck or trailer cargo doors, pedestrian storefront or automatic-entry doors, glass or hollow-metal walk-through doors, locks or closers, parts-only orders, or structural concrete, pit or slab work.
Covered on this page: dock seals and shelters, including pads, fabric, head curtains and frames; dock bumpers and their mountings; portable dock plates and boards, for assessment and replacement; dock lights and their arms and switches; communication lights at the bay; barrier gates and dock guards; chock holders and bay accessories.
Handled elsewhere: installed levelers on dock leveler repair; trailer restraints, dock locks and interlock systems on trailer restraint repair; the doors themselves on overhead, roll-up, high-speed or fire-rated pages.
Specifically excluded: dock face concrete, pit walls, slab and approach apron repair; selling parts for you to fit yourself; and refrigeration equipment behind a cold-storage opening.
What affects the price on dock equipment repair
We can't quote your bay from a web page. The price depends on which equipment failed, how many bays, and what the mounting surface is like underneath. Here's what to ask before you authorize work.
| What drives it | Why it moves the number |
|---|---|
| Diagnostic or trip charge | Getting a qualified person to the bay is commonly billed separately from the work |
| How many bays | Six bays of bumpers is a program; one bay is a visit |
| Seal versus shelter | Different products, different mounting, different price |
| Opening size | Opening dimensions, trailer fit and product design affect the specification and price |
| Mounting condition | If the wall, frame or dock face behind the equipment is damaged, the scope grows |
| Trailer mix | A varied trailer fleet may point at a shelter rather than a seal, which changes the product |
| Insulation and climate | Conditioned and refrigerated bays justify different specifications |
| Electrical scope | Dock lights and communication lights may involve wiring and a separate trade |
| Parts availability | Stock, matching profiles and made-to-size components affect lead time |
Ask outright: Is the diagnostic separate and credited? Is this per bay or for all of them? Does the price include removing and disposing of the old equipment? What happens if the mounting surface turns out to be damaged? What is the lead time on a made-to-size seal or shelter? Are there after-hours rates?
The independent company that accepts the work sets its own prices and terms.
Repair the equipment, or replace it?
Ask whether the damaged part can be restored under the manufacturer's instructions and whether the remaining assembly and mounting are sound. Worn-out pads, deformed frames, unsuitable trailer fit or unavailable parts can make replacement the better scope; portable plates and boards still need their own rating and disposition assessment.
Choose a company that can match the seal, shelter or bumper to the opening and trailer mix, not just replace what was there. Ask who handles damaged mounting surfaces and any electrical work, and get those boundaries in writing.
Local rules that matter for dock equipment work
Most of this equipment is attached to the building. Ask the permit office about the actual scope, especially altered mounting, structure or electrical work.
| What is changing | What to ask, and who confirms it |
|---|---|
| Replacing seals, shelters or bumpers in kind | Inside Pittsburgh, check the scope against the city's work not requiring a permit list. Do not assume every building attachment needs a permit — and do not assume none does. |
| New or altered electrical for dock lights or communication lights | Inside Pittsburgh, electrical permits require a separate PLI Electrical Trade License (PLI permit issuance). Ask who holds it. |
| Work that touches the dock face, pit or slab | Different trade and a different approval path. Ask who is responsible for the concrete scope. |
| Anywhere outside Pittsburgh city limits | The municipality containing the parcel decides, directly, through a certified third-party agency, or via L&I (PA UCC). Ask which office covers the address. |
| A portable plate or board that is damaged | Start with the manufacturer-rating and disposition question. Ask what the device's rating and the manufacturer's instructions say before anyone puts it back in service. |
We do not determine whether a permit applies to your bay. The rule, the office and the question are the ceiling; the provider and the issuing office confirm.

Common questions
Our dock plate is bent. Can it be welded?
Do not assume so, and do not have it welded on a hunch. A portable plate or board is engineered equipment with a rating; bending and cracking can affect that rating in ways that are not visible, and repair may not be authorized by the manufacturer at all. Get it assessed, check the device's own rating and the manufacturer's instructions, and keep it out of service in the meantime.
Is a dock seal or a dock shelter better?
Neither, in the abstract — it depends on your trailer mix. Seals work well when trailers are consistent in size, because the trailer compresses the pads. Shelters tolerate variation better, because the curtains drape over the trailer rather than being crushed. A provider who asks about your trailer mix before recommending one is asking the right question.
Do missing bumpers really matter?
Yes. Bumpers set how far the trailer sits from the building, which determines how the leveler lip lands and how the seal compresses. Missing or worn bumpers expose the dock face and equipment to impact damage.
Can you replace the concrete under our leveler while you're here?
No. Concrete pit, slab and dock-face work is structural work for a different trade, and it is outside this scope. If a bumper problem has damaged the dock face, expect two trades and sequence them — repairing the concrete after new bumpers go on is the wrong order.
