Which part of the loading bay needs attention?
A dock bay is a handful of separate devices doing separate jobs around the same opening. A seal is not a shelter. A bumper is not structure. A loose plate is not a leveler. Sorting that out on the call saves a wasted trip.
| What you see | What it does | What to report | Where the full answer is |
|---|---|---|---|
| Foam pads or fabric around the opening that the trailer presses into | Dock seal or shelter — closes the gap around a backed-in trailer | The tear or gap you can see, and the bay | Seals and shelters |
| Rubber or laminated blocks bolted to the dock face | Dock bumper — takes the trailer's impact so the dock does not | Crushed, loose, or missing, and which bay | Dock bumpers |
| A loose steel or aluminum bridge you set in place | Portable dock plate, bridge plate, or dock board | Its rating if the tag is readable from a safe position, and the damage | Plates and boards |
| A steel deck with a lip, built into the dock | Dock leveler — permanently installed | Which part stopped | Dock leveler repair |
| A device that grips the trailer's rear bar or wheel | Vehicle restraint, often called a dock lock | Whether a trailer is held or cannot be secured | Trailer restraint repair |
| Arm-mounted light shining into the trailer | Dock light — illumination, not signalling | Which bay and what it is doing | Lights and chocks |
| Red/green lights inside and outside the bay | Communication lights — part of the restraint system | Which light shows what | Restraint controls |
| Wheel chocks | Loose blocks placed at the trailer wheels | Damaged, missing, or not holding | Lights and chocks |
If a maintenance file names a brand — a Kelley seal or shelter, a Bluff plate or board — mention it. It speeds up the parts conversation. It is identification only; nothing here claims an authorized-dealer relationship with any manufacturer.
Can a torn dock seal or damaged shelter be repaired?
Sometimes, and it depends on which one you have and what failed. A dock seal is a set of compressible pads, usually foam under a tough fabric cover, mounted around the opening so a backed-in trailer squeezes against them. A dock shelter is a framed hood with curtains or a fabric head pad that drapes over the trailer instead of being crushed by it. Different construction, different failure modes, different repairs.
What usually gets replaced rather than patched: a cover that has split along a seam or worn through to the foam, a head curtain that has torn free of its track, and pads that have taken a permanent set and no longer spring back against the trailer.
| What you can see | The scope question | What moves the price | Where the line is |
|---|---|---|---|
| Torn fabric or split cover | Replace a component, or the assembly? | Size, construction, whether parts match what is installed | You do not need to inspect anything up close |
| Frame or head pad pulled loose | How it mounts, and what the mounting looks like now | Condition of the wall or header attachment | Structural repairs to the building are excluded |
| A visible gap around a docked trailer | Is it a damage problem or a fit problem? | Trailer mix, opening size, how the seal was originally specified | Nobody here can promise an airtight seal |
| The same seal keeps tearing | Fit, trailer mix, driver approach, or the wrong product for the bay | A different product may be the honest answer | No failure-rate claims are made on this page |
A note on energy savings: a good seal helps a conditioned building. What it saves depends on your building, your climate control and how long your doors sit open. No percentage on a web page is your number.
What does dock bumper replacement include?
Dock bumpers are the wear part between a trailer and your dock wall. When a bumper is crushed flat, hanging off, or gone, the trailer can contact parts of the dock face or adjacent equipment that are not intended to take that impact.
What to ask about: the replacement bumper type (molded rubber, laminated rubber pads, steel-faced units — different products for different abuse levels), the mounting hardware, and the condition of what it bolts to. That last one matters. If the anchors pulled out and took concrete with them, you have two jobs: an equipment job and a structural one.
| What you can see | The question to ask | What is included, what is not |
|---|---|---|
| Worn or crushed bumper still attached | Which replacement type suits this bay's traffic? | Equipment and fasteners in scope |
| Missing bumper, visible anchor holes | What condition is the mounting in? | Do not assume the substrate is intact |
| Cracked or spalled concrete at the dock face | Where does equipment work stop? | Structural concrete, pit and slab work is excluded here |
| Bumpers fine but the trailer still hits the building | Is the bumper the wrong height or projection for your trailers? | A spec question, not a repair question |
Is the "dock plate" portable — and can a damaged one be repaired?
First, the word. A portable dock plate, bridge plate, or dock board is a loose bridge you set between the dock and the trailer and pick back up. An installed leveler is not a plate, even though everybody calls it one. Say whether the thing is loose or built in.
Second, use the manufacturer's rating or other reliable equipment identification—not the material, size, or how heavy it feels—to decide what traffic a portable device is intended to carry. MHI distinguishes dock boards, typically intended for heavier material-handling loads, from dock plates, typically used for lighter hand-loading or hand-truck applications. The specific device's documented rating and intended use still control. If its identification cannot be established, treat its capacity and intended use as unknown until a qualified provider or manufacturer can verify them.
A bent, cracked or damaged device should not be assumed repairable or returned to service after an improvised weld. Ask whether the manufacturer supports a repair and what inspection or acceptance documentation is required.
| What you already know | What still has to be established | The question for a qualified provider | Do not assume |
|---|---|---|---|
| The device is loose and movable | Its exact model and intended application | Which original specification applies to this device? | That anything called a "plate" takes a forklift |
| A capacity is recorded in your files | The actual combined weight of truck plus load | Is it suitable for the equipment and load we run now? | That size or steel construction proves capacity |
| It is visibly bent or cracked | Whether repair is supported at all | Does the manufacturer support a repair, and what are the acceptance criteria? | That welding restores the original rating |
| The tag is gone or unreadable | Identification, or replacement | Can this device be identified, or should it be replaced? | That an unmarked device is fine because it always worked |
| You need something today | Suitability and your own facility's approval | What properly specified device is acceptable here? | That any plate can substitute for a failed leveler |
MHI's official LODEM page describes dock boards and dock plates as portable dock leveling devices covered by design, use and testing standards. It does not determine a Michigan legal requirement or the fitness of a particular device.
Dock lights, chocks and what they actually prove
Two different things get called "dock lights," and mixing them up causes real confusion on a call.
- Illumination lights — the arm-mounted lamp that lets a forklift operator see inside a dark trailer. A failed one is a visibility problem.
- Communication lights — the red/green pairs inside and outside the bay that tell a driver and a dock worker what is happening. Those are part of the restraint and dock control system, and they belong with the restraint page.
A green light is a signal, not proof. It tells you what the control system believes. It does not prove a trailer is physically secured, and treating it as proof is how people get hurt when something in the chain has failed.
Wheel chocks are simple and they still matter. A chock and a mechanical restraint are not automatically interchangeable for your facility's purposes — that is a question for your own safety program and the applicable rules, not for a repair page. If chocks are damaged, missing, or not holding on your dock surface, that is worth reporting along with everything else. Further reading on how the two compare: vehicle restraints vs wheel chocks.
If new wiring or a new circuit is part of any lighting or control work, that is separate electrical scope in Michigan. Michigan electrical permit information
Which accessory failures should you report first?
Say whether the bay is out of use, then describe what you can already see. Keep people clear and follow your facility's existing process for taking the affected bay out of use.
| What you noticed | What a qualified provider may assess | How to report it |
|---|---|---|
| Torn seal or shelter | Construction and compatible replacement | The bay and the damaged section |
| Crushed or missing bumper | The accessory and its mounting condition | The bay and what the impact looked like |
| Damaged portable plate or board | Identification and whether repair is supported | What you know from the tag and the file |
| Dock light out or damaged | Which kind of light and what failed | Which bay, and which light |
| Lights disagreeing with each other | The control system and connected equipment | What each light is showing — no test required |
| Restraint holding or refusing to grab | Device, controls, vehicle interface | Held versus cannot-secure, and the bay |
Which facilities and scope fit?
Call about dock accessories at warehouses, distribution and receiving buildings, manufacturing plants, food and beverage facilities, commercial workshops and other commercial loading bays. A small receiving dock with two bays qualifies on equipment, not size.
What is here: accessory repair and replacement, portable-device questions, dock lighting, and the repair-versus-replace conversation for each. Installed levelers and full restraint tasks have their own pages.
This page is not for residential garages, boat docks or boat lifts, truck and trailer cargo doors, pedestrian storefront or automatic-entry doors and their locks and closers, parts-only orders, or structural concrete, pit and slab work. Dock lifts, yard ramps and rebuilding a dock structure are not part of this catalogue either — say what you have and you will be told plainly if it is outside scope.
What happens when you call?
- You describe the problem. Facility location, bay, and what is damaged.

What affects dock equipment repair or replacement costs?
We can't quote your exact 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.
| What drives the number | Why proposals differ | Ask before you approve |
|---|---|---|
| Visit and assessment | How many accessories are involved changes the visit | What does the initial visit include? |
| Seal or shelter construction | Pad, fabric, frame — and whether the parts match what is installed | Component or complete assembly? |
| Bumper type and mounting | Product choice and the condition of what it bolts to | Where does the equipment quote stop? |
| Portable device disposition | Identification, and whether repair is supported at all | What supports repairing this rather than replacing it? |
| Lighting, controls, restraint interface | Device compatibility plus any wiring | What electrical or specialist scope is separate? |
| Parts and access | Availability and how the bay has to be freed up | What needs approval before work continues? |
Should an accessory be repaired or replaced?
Condition, compatible parts, and whether the manufacturer supports the repair. Cheap-looking is not the same as safe to repair — a portable board is the clearest case of that. And damaged supporting structure is a different job from replacing the accessory bolted to it. Ask for those to be separated in the proposal so you can see both numbers.
How should planned dock maintenance be scoped?
A useful planned dock visit names the assets and says what gets checked on each one. Ask for findings in writing, and ask what needs separate approval before anyone starts turning wrenches.
| Asset | What to scope | What you should get back |
|---|---|---|
| Seals and shelters | Construction, condition, fit to the trailers you actually get | Findings plus a replacement recommendation where needed |
| Bumpers | Wear, mounting, and the condition of the dock face behind them | A clear line between equipment and structure |
| Portable plates and boards | Identification, rated application, visible condition | A documented disposition for each device |
| Dock lights and controls | Which devices, and what is electrical scope | A specialist handoff where it is needed |
| Installed levelers | The mechanism and the manufacturer's requirements | See leveler maintenance |
| Restraints | Device and control condition | See restraint repair |
This is a dock inventory, not a garage-door service interval with a different label. If someone proposes a fixed quarterly schedule, ask what it is based on — the manufacturer's instructions and how hard your dock runs, or their standard package.
Which Michigan and local checks apply?
| The work | Where to start | The useful question |
|---|---|---|
| Portable device use and disposition | MIOSHA general industry standards plus the manufacturer's instructions | Which application criteria govern this device? |
| Replacing accessories, or altering installed equipment | The municipality covering the address — Detroit BSEED or the local office | Which scope needs review beyond replaceable equipment? |
| Lighting or control wiring | Michigan electrical permits | Is electrical work included and correctly assigned? |
| Damaged concrete, pit or slab | A separate structural scope | How is excluded structural work identified in this quote? |
| Any other Michigan municipality | LARA Statewide Jurisdiction List (PDF) | Which agency enforces at this address? |

Questions about dock equipment repair
Can a bent dock plate just be welded and put back in service?
Do not assume it. Welding can change the metal, and a repair the manufacturer does not support is not something to trust under a loaded forklift. Ask whether repair is supported for that specific device and what the acceptance criteria are.
Is a dock board always suitable for my forklift?
No. Suitability comes from the rating on the device and the actual weight of truck plus load. Material, size and how heavy it feels prove nothing.
Can I call about a seal, shelter or bumper without knowing the brand?
Yes. Name the bay, say what the accessory is, and describe what you can see. A brand from a maintenance file is a bonus.
Does bumper replacement include repairing the concrete dock face?
No. Structural concrete, pit and slab work is excluded here. If the anchors took concrete with them, ask for the equipment work and the structural work to be quoted as two separate things.
