What's on and around the dock face

This page covers dock seals and shelters, plates and boards, bumpers, lights, chocks and related accessories. Most people call it “the dock stuff.” The equipment name helps separate the repair scopes.

If it's the deck that tilts into the trailer, that's the dock leveler. If it's the hook or arm that grabs the trailer, that's a trailer restraint.

Dock plate, dockboard, or installed leveler?

A portable plate and an installed leveler have different ratings and repair questions. Identify which one you already have before assuming it can be repaired or used by a forklift.

An installed leveler is part of the building. It sits in a pit in the dock floor or is bolted to the dock face (that's an edge-of-dock leveler — short, mounted on the face, still installed equipment). You don't move it. A dock plate or dockboard is portable. It bridges between loading surfaces and has its own capacity and manufacturer-specified handling requirements.

DeviceHow you can tellInstalled or portableWhat it's rated forWho to call
Installed dock levelerSits in a pit; deck is flush with the dock floorInstalledRated as installed equipment for that dockDock leveler repair
Edge-of-dock levelerShort unit bolted to the dock face, not in a pitInstalledRated as installed equipmentDock leveler repair — this is the one people mistake for portable
Dock plateLoose, usually lighter, often with handles or lift loopsPortable; model-specific handlingIts own stamped or plated rating. Often lighter-dutyThis page
DockboardLoose, heavier, usually with side curbs and lock legsPortable; model-specific handlingIts own stamped or plated ratingThis page

Why the confusion exists, and why it matters. OSHA's definition of dockboard at 29 CFR 1910.21 is broad enough to take in bridge plates, dock plates and dock levelers together, in one word. The ANSI standards do the opposite — MH30.1 covers dock leveling devices and MH30.2 covers portable dock leveling devices, as two separate standards (MHI LODEM summaries). Both checked September 18, 2026.

So one word, two very different pieces of equipment, two very different repair answers.

Three things not to assume about a damaged portable plate:

  1. Don't assume it can be welded. A plate carries a rating that depends on its material, thickness and condition as manufactured. A weld repair may or may not be something that manufacturer permits. That's a provider and manufacturer question, not a shop-floor decision.
  2. Don't assume it's still rated. Bent, cracked, gouged or previously repaired changes the picture. The rating stamped on it describes it as it was, not as it is now.
  3. Don't assume "plate" means forklift-rated. Plenty of portable plates are specified for pallet jacks and hand trucks, not for a loaded lift truck. Thickness and weight are not a rating.

OSHA 29 CFR 1910.26 requires dockboards to be capable of supporting the maximum intended load, and addresses run-off protection, securing, protection against transport-vehicle movement and safe handling. Read the wording rather than a summary of it: the rule calls for measures such as chocks or sand shoes, and handholds or other means — non-exclusive lists. The employer applies the full rule to its own operation. Checked September 18, 2026.

If a plate is damaged, take it out of service through your facility's normal process. Don't test it with a loaded lift to see how it feels.

Dock seals and shelters

A seal and a shelter do the same job two different ways, and the repair conversation differs.

A seal closes against the trailer; familiar designs use foam-filled fabric pads, and inflatable designs also exist. A shelter generally uses a frame and curtains around the trailer opening. Depending on the design, its curtains or frame may deflect or compress. The provider checks the actual assembly rather than choosing parts from the name alone.

What gets assessed: the fabric or cover, the foam or the frame behind it, the mounting and fasteners, and the actual trailer fit at that bay. That last one matters — a seal that keeps tearing in the same place is often telling you something about how trailers are landing at that dock, not just that the fabric is old.

On a Chicago dock this is more than a comfort item. A torn seal at a cold-storage or food facility moves conditioned air out and weather, dirt and pests in, all year, and shredded fabric catches on the next trailer and tears further. Ask the provider whether the answer is a pad replacement, a full assembly, or a fit problem worth solving once.

What to report: which bay, which part of the seal or shelter, how far the tear runs, and whether anything is currently catching on trailers.

Dock bumpers

A bumper protects the dock face from backing-trailer impact. A missing or damaged one is worth reporting before the next contact damages the mounting or nearby equipment.

When a bumper is crushed, torn or gone, the dock face and nearby equipment can be exposed to impact. Ask whether the work is a bolt-on bumper replacement or whether the mount, concrete or leveler also needs a separate assessment.

What gets assessed: the bumper itself, the mount and fasteners, the dock face behind it, and whether the projection still suits the trailers using that bay. Sizing is a site question — projection, height and mounting pattern all have to suit the dock and the traffic, so ask what the quote assumes about the existing mount and trailer fit.

Boundary: the bumper and its mounting are in scope. Rebuilding a spalled or broken concrete dock face is structural concrete work and goes to a concrete contractor.

What to report: which bay, whether the bumper is crushed, torn or missing entirely, and whether trailers are already contacting the dock face.

Dock lights, communication lights and chocks

Three different things that often get lumped together on a call.

A dock light is the swing-arm lamp that lights the inside of the trailer. Failures are usually the lamp, the arm, the cord or the switch — and it's worth saying which, if you know.

Communication lights are the red/green pairs inside and outside the bay that tell the driver and the dock crew when it's safe to move or to enter the trailer. When those show the wrong state, that is a reportable fault, not a nuisance — people make decisions on them. If the lights are tied into a trailer restraint, the restraint page covers that connected system, because the light may be reporting a restraint condition accurately. → Trailer restraint, communication and interlock repair

Wheel chocks are usually a supplier order rather than a repair call. Do not assume a loose chock and an engineered restraint are interchangeable for your operation. Your safety team applies the equipment instructions and the relevant securement requirements; OSHA § 1910.26 names chocks as one example, not the only method.

Strip curtains at interior openings are in scope as equipment. A powered door behind them is a different page.

What belongs in dock-equipment maintenance?

A planned dock visit should identify each accessory, record its condition and separate service from replacement. A door tune-up alone does not cover plates, shelters, bumpers or communication equipment.

EquipmentWhat to put in the agreed scopeWhat to ask for in the record
Portable plates and boardsIdentification, capacity records and condition; manufacturer-approved disposition of damageUnit identity and any restriction or replacement recommendation
Seals and sheltersCovers, pads or frame, mounting and trailer fitThe damaged section and whether repair or assembly replacement is proposed
BumpersCondition, projection and mounting assessmentWhich bay and whether the supporting structure needs separate work
Dock lights and communication equipmentLamp/arm condition and model-specific indication checksAny unresolved signal or control fault
Connected levelers and restraintsSeparately agreed equipment service and interlock checksWhich equipment was checked and what remains outside scope

Use the manufacturer’s schedule and the facility’s actual traffic and environment—not one interval for every component. MHI’s public equipment scopes distinguish installed levelers, portable devices and restraints. For the larger programme, see planned commercial door maintenance; for those mechanisms, use leveler repair and restraint repair.

What we take calls about — and what we don't

Commercial and industrial loading-dock equipment and building-mounted commercial doors: warehouses, distribution centers, plants, cold storage, food and beverage facilities, fleet garages, auto-service bays, workshops and commercial self-storage.

Not in scope: residential garages; boat docks and boat lifts; truck and trailer cargo doors; pedestrian storefront, automatic-entry, glass and hollow-metal walk-through doors with their locks and closers; parts-only orders; and structural concrete, pit and slab work.

Existing labels or records may name Rite-Hite, Blue Giant or Nordock. These manufacturers offer dock accessories and equipment; the name helps identify the product, not prove an Uptime service affiliation. You do not need to retrieve a label before calling.

What to say when you call

Example wording. It's an example, not a script, and not a real job.

"The left seal pad is shredded top to bottom on bay 3 at our Chicago warehouse and the bumper under it is gone, and I can give you the address."

Three steps after you call:

  1. You describe it. Facility, bay, and which piece of equipment is damaged.
  2. Your request may be shared. Calls may be shared with an independent commercial dock-and-door repair company.
  3. That company takes it from there. They confirm the address, scope, availability, price and scheduling, plus their own contract, work and warranty terms.

Useful but not required: how many bays are affected, whether trailers are still using the bay, and any rating or model plate you can already read from a normal standing position. Don't climb, and don't lift a damaged plate to look underneath it.

If you reach voicemail, leave the facility address, the door or dock number if known, what's wrong, and a callback number.

What affects dock equipment repair cost

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

What drives itWhy it moves the numberWhat to ask
Seal versus shelter constructionDifferent assemblies, different parts"Is this a pad, or the whole assembly?"
Pad replacement versus full unitSometimes one pad, sometimes the set"Why this scope and not the smaller one?"
Bumper size, projection and mountingHas to suit the dock and the trailers"How was the size decided?"
Whether a plate is repairable at allA portable device may need replacing, not repairing"What does the manufacturer allow for this device?"
Number of bays in one visitMobilisation and access can change the comparison"What's the price if we do all four now?"
Access and live-dock timeWorking across active bays takes scheduling"Which bays do you need, and when?"
Structural findings behind the equipmentDamage behind a bumper may be outside this scope"What did you find behind it?"

Rules that touch this equipment

OSHA 29 CFR 1910.26 on dockboards is the main one, and it's worth reading rather than paraphrasing — capacity, run-off protection, securing, protection against transport-vehicle movement and safe handling, with the non-exclusive wording noted above. ANSI MH30.2 is the standard for portable dock leveling devices, separate from MH30.1 for installed ones. Both checked September 18, 2026.

If accessory work is part of an alteration to a conditioned opening, ask the building official which energy, building or electrical provisions apply. The 2024 Illinois Energy Conservation Code took effect November 30, 2025, but not every accessory service call triggers the same requirements. The provider and issuing office confirm the actual scope. Checked September 18, 2026.

Questions about dock equipment repair

Can a cracked dock plate be welded and put back in service?

Don't assume it. Whether a repair is permitted, and whether the device keeps its rating afterwards, is a manufacturer and provider question about that specific device. Follow the facility's process for keeping damaged equipment out of use; do not handle it to investigate.

Do you replace just one seal pad?

Ask whether a compatible replacement pad is available and whether the frame and mounting are sound. If the provider proposes the whole assembly, ask what finding makes that scope necessary.

Is an edge-of-dock leveler portable?

No. It's short and it's bolted to the dock face rather than sitting in a pit, but it's installed equipment. It goes to the dock leveler page.

How do I know what my dock plate is rated for?

Use the manufacturer's capacity marking and records for that particular device. Mention a rating you already know or have recorded; do not move or approach damaged equipment to find one. A plate's weight, thickness or material is not a capacity rating.
