This page covers the equipment around the opening — seals, shelters, bumpers, portable plates and dock lights. The door is on commercial garage and overhead door repair or roll-up and rolling-steel door repair. The installed leveler is on dock leveler repair. The restraint and its lights are on trailer and vehicle restraint repair.

Is the dock position unsafe or unusable right now?

Call (385) 325-7138 and say whether a damaged plate, missing bumper or hanging equipment has taken the position out of use. Keep people and traffic clear through the facility's established process; the independent provider confirms the repair scope and availability.

Is it an installed leveler, or a portable plate you can pick up?

A pit or edge-of-dock leveler is installed in or on the dock. A portable dock plate or dock board is a separate bridging device moved using the handling method its manufacturer specifies, and the rules around it are different. That distinction is the most useful thing on this page.

Federal rules treat portable dockboards as their own category. 29 CFR 1910.26 requires that dockboards be capable of supporting the maximum intended load; that dockboards first put into service on or after January 17, 2017 be designed, constructed and maintained to prevent transfer vehicles from running off the edge, unless the employer demonstrates no such hazard exists; that portable dockboards be secured against unsafe movement, with a limited provision for sufficient contact where securing is infeasible; 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 to permit safe handling. 29 CFR 1910.178(n)(11) addresses dockboards and bridge plates: they must be properly secured before being driven over, crossed carefully and slowly, and that their rated capacity must never be exceeded.

Fall protection applies too. Under 29 CFR 1910.28(b)(4), each employee on a dockboard must be protected from falling 4 feet or more by a guardrail system or handrails — and the exception is narrow. It requires all three of: the dockboard used solely for materials-handling with motorized equipment, no fall hazard greater than 10 feet, and employees trained under § 1910.30.

ANSI's catalog lists MH30.1-2022 for dock leveling devices and MH30.2-2022 for portable dock leveling devices — the family that includes plates and boards.

The name does not tell you the rating

Manufacturers use "dock plate" and "dock board" inconsistently, and it causes real problems. Bluff Manufacturing's aluminum dock plates are described for manual handling equipment within their rated capacity — not for forklift or motorized traffic. Copperloy uses "dock plate" for both light aluminum products and steel products intended for fork-truck use. Vestil publishes several distinct plate and board families with different curb and construction arrangements.

So: a device's name, its size, and what it looks like next to the one on the bay beside it do not establish what it is rated for. The label and the manual do.

If a portable plate or board is damaged

Never assume a damaged portable device can be welded, straightened, returned to service, or driven over. A bent, cracked or curled plate, a board with damaged legs or curbs, or a unit with missing or damaged handholds comes out of use.

Tag it out of service through your facility's normal process and arrange a qualified assessment. Do not have anyone lift, drag or reposition a damaged plate to inspect it — these devices can be heavy and awkward, and their handling method depends on the model. Whether it can be restored depends on the model, the damage, the original rating and what the manufacturer supports. That is a decision for the provider and the manufacturer, not for the bay.

What needs dock equipment repair at this position?

Seals and shelters

A dock seal uses compressible pads that the trailer presses into. Its fit depends on the trailer dimensions and the opening. A dock shelter uses curtains around the opening and can accommodate a wider range of trailer heights and widths. Sealing performance depends on the design and fit; the name alone does not decide it.

Which one suits a position depends on the trailer mix, how tight the seal needs to be, and how much contact the equipment takes. A facility running mixed van and refrigerated trailers has a different answer than one running a single dedicated fleet.

Repair the pads, or replace the unit? That depends on what has actually failed. Pads and curtains are commonly replaceable on their own. Frames, head assemblies and mounting hardware push the job toward replacement.

The point most people miss: repeat seal damage needs a cause check. Trailer-height mismatch, worn bumpers or an angled approach can contribute to damage. Ask the provider to check the fit and contact pattern before replacing the torn material.

Bumpers, and why they matter to everything else

Dock bumpers absorb the impact of a trailer backing into the dock. When they wear down or disappear, the dock and building lose that protection.

They come in laminated rubber, molded rubber and steel-faced varieties, in different thicknesses and projections. Which is right depends on trailer traffic, trailer bed height relative to the dock, and how much the position is used.

What to look at without touching anything: how much bumper is left compared with a newer position, whether any are cracked through or separating, whether any are missing entirely, and whether there are fresh contact marks on the concrete or the door track above them. Ask the provider to check bumper projection and surrounding contact damage together.

The rest of the position

Dock lights. Arm-mounted lamps that swing out over the trailer. What fails: the arm joints, the head, the fitting, and the switch. Fixture condition, mounting and any electrical work determine the scope.

Wheel chocks. Chocks belong to the securing conversation rather than the equipment conversation. They are covered alongside restraints on trailer and vehicle restraint repair.

Strip curtains. Plastic strip curtains in an interior opening are generally a supply item rather than a service call. Mention them if they are part of a larger dock job.

Dock lifts, including scissor-type loading platforms. Real equipment on some docks, and a genuine service need. Say so on the call and the request gets described accurately; the provider confirms whether it handles that equipment.

Call about the position, not just the part.

What is covered here, and what is not

Covered: dock seals and shelters; dock bumpers; portable dock plates and boards, including assessment and replacement; dock lights; the accessory equipment around a dock position; dock lifts where a provider handles them.

Not covered: installed levelers, on dock leveler repair; restraints and communication lights, on trailer and vehicle restraint repair; the door, on its own page; boat docks and anything on the water; residential equipment; truck and trailer cargo doors; parts-only orders; structural concrete, pit reconstruction and dock-face rebuilding.

And the one thing not to assume: that a damaged portable plate or board can be repaired back to its original rating. Any repair decision needs the original manufacturer's support for that model and damage; otherwise, ask about replacement.

Which company should assess the equipment?

Ask for experience with the actual equipment and manufacturer-supported replacement parts or repair options. For portable plates and boards, the company should address the model, rating and intended traffic; for seals and bumpers, ask it to check fit and mounting rather than quote from a photo alone.

What happens after you call

1. You describe it. Facility address, dock position, what is worn or damaged.
2. Your request may be shared with an independent commercial dock-and-door repair company. If one takes it, that company — not Uptime — confirms availability, scope, pricing, scheduling, and its own contract, repair and warranty terms.
3. You deal with that company directly from there.

Example wording for the first sentence: "The seal on bay 5 is torn most of the way down at our warehouse in Baltimore, 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.

Useful, but not required

How many positions are affected. Whether the position is refrigerated or ambient. Trailer types that use it. Rough dock height. Any visible label on a portable device — the model and rated capacity if it is printed where you can already see it. You can call without a single one of these, and you should not go near damaged equipment to get them.

What affects the price?

We can't quote your exact dock equipment work from a web page. The price depends on the equipment, the damage, parts, and access. Here's what to ask before you authorize work.

Ask: is this priced per position or for the whole job? Is it a starting price, a scoped fixed price, an estimate or a final quote? Are the pads, curtains or bumpers stock items or made to size? Is removal and disposal of the old equipment included? Does the price include fixing what caused the wear, or only replacing the worn part?

Ask what caused the wear, not just what it costs to replace.

Which rules and local checks matter here

The federal dockboard provisions above are the ones that come up most, and they are worth knowing because they are so often quoted loosely. Two accuracy notes: the wheel-stop provisions at 1910.178(k)(2) and (k)(4) are railroad-car provisions and do not apply to trailers, and the 4-foot dockboard guardrail exception at 1910.28(b)(4)(ii) needs all three of its conditions, not one.

For a local permit check, describe the actual work: accessory replacement, changes to mounting or the dock face, and any wiring or circuit work. The property's permit office confirms which approvals apply. Maryland's electrical licensing requirements matter when electrical work is included (Maryland State Board of Electricians). The permit-office map for all seven metro jurisdictions is on the Baltimore service area page.

Where can you call about dock equipment?

Commercial and industrial facilities in Baltimore City, Baltimore County, Anne Arundel, Howard, Harford, Carroll and Queen Anne's. The independent repair company confirms the facility address, equipment scope, availability, pricing, and scheduling.

Local pages: Sparrows Point, Jessup, Aberdeen, Glen Burnie.

Dock equipment questions

Is a dock plate the same thing as a dock leveler?

A portable dock plate or board is different from an installed pit or edge-of-dock leveler. The portable device bridges a gap and has its own rating, securing features and approved handling method. Tell the provider whether it is portable or installed; do not move it just to identify it.

Our dock plate is bent. Can it be repaired?

Take it out of service first, through your facility's normal process. Whether it can be restored depends on the model, the damage and what the original manufacturer supports — welding or straightening must not be assumed to restore the rating. Do not put a damaged plate back under a forklift on a judgment call.

Do worn bumpers really matter if the door still works?

Yes. Bumpers help protect the dock and building against trailer impact. Worn or missing bumpers need assessment even when the door still works; there is no reliable timetable for when other damage will show up.

Seal or shelter — which should this position have?

A compression seal uses pads against the trailer; a shelter uses curtains around the opening and can accommodate more trailer variation. The right answer depends on your trailer mix, opening and required environmental seal. Describe what backs into that bay so the provider can assess the fit.
