What counts as dock equipment here
This page covers the dock surround — everything around the opening that is not the leveler and is not the door. Seals and shelters, loading dock bumpers, portable plates and boards, dock lights, and wheel chocks.
It is normal to find several of these worn at once, because they wear together. Reporting four bays on one call is easier for everybody than four calls.
For the rest: the dock leveler is the plate built into the dock floor. Trailer restraints and dock locks are the devices that hold the trailer. The door itself is rolling steel, sectional and overhead or high-speed.
And a clarification, because the words collide. A loading dock bumper is the rubber block bolted to your dock face. It is not a car bumper, and it is not a brand of dock product — both of those come up when people search for this, and neither is what this page is about. This is also loading dock equipment, not boat docks, and not the concrete the dock is built from.
Not sure which one it is? Call and describe it.
Dock seals and shelters
A dock seal is a set of compressible pads around the opening that the trailer backs into and presses against. A dock shelter is a hood or curtain frame the trailer backs under, with side curtains and a head curtain. Seals give you a tighter seal on a narrow range of trailer sizes; shelters handle a wider mix and leave more of the opening usable.
What failure looks like: torn or delaminated fabric, foam flattened or gone hard, backing boards pulling away from the wall, a shredded head curtain, loose mounting, and daylight around a docked trailer.
Why it matters here. A shot seal is a heating bill and a wet dock floor through a Western New York winter. And fabric that is already torn holds water, freezes, and tears further on the next trailer — which is why a small tear in November is a curtain replacement in February.
What a qualified provider inspects: fabric and backing condition, mounting and fasteners, the dock face behind, clearance and trailer fit — and whether the bumpers in front of them are still doing their job, because a seal wears out fast once the bumpers stop standing the trailer off.
Loading dock bumpers
Bumpers hold the trailer off the dock face and off the door above it. They are the cheapest part on the dock and the one whose failure costs the most.
What failure looks like: rubber crushed thin, laminated bumpers separating into layers, the steel backing plate visible, bumpers missing entirely, and fresh damage to the dock face or the door above.
The chain worth understanding: worn bumpers let trailers reach the dock face, which damages the face, the seals, the leveler frame and the door above it. Replacing bumpers is the maintenance item that prevents three other repairs.
What a provider inspects: remaining thickness, mounting hardware and anchors, dock face condition behind them, projection relative to the leveler and the door, and whether the trailer height mix is causing uneven wear.
Portable dock plates and dockboards
The loose plate somebody carries or drags across the gap is not a small dock leveler. It is a rated product with its own standard and its own rules.
ANSI MH30.2, Performance and Testing of Portable Dock Leveling Devices, defines performance and testing requirements for the design, use and maintenance of portable dock leveling devices. It separates dockboards, which have beam-like supporting members, from dockplates, which are lighter and do not. Built-in levelers are a different standard entirely — that is dock leveler repair.
Federal rules are specific about these. Under 29 CFR 1910.26, dockboards must be capable of supporting the maximum intended load; portable dockboards must be secured by anchoring them in place or by using devices that prevent them moving out of a safe position; measures such as wheel chocks or sand shoes must prevent the transport vehicle moving while employees are on the dockboard; and portable dockboards must have handholds or other means for safe handling. 29 CFR 1910.178 adds at (n)(11) that they must be properly secured before being driven over, driven over carefully and slowly, and that their rated capacity is never exceeded.
So here is the rule, said once and said plainly. Never assume a bent, cracked or damaged portable plate can be welded, straightened or put back into service. Never drive a forklift over one that is not secured or is not sitting right. Take it out of use and get it evaluated for replacement.
That is why this section is about evaluation rather than "repair." A damaged rated product is a replacement decision, and pretending otherwise is how people get hurt.
Dock lights, chocks and the rest of the bay
Dock lights. The articulated arm light over the opening, and the bay lighting behind it. What fails: the fixture, the arm, the wiring, the switch. A dark trailer is a loading problem before it is a lighting problem, and it is usually the cheapest thing on this page to put right.
Wheel chocks. Federal rules put it directly: the brakes of highway trucks shall be set and wheel chocks placed under the rear wheels to prevent the trucks from rolling while they are boarded with powered industrial trucks. Chocks are a securement item. The restraint that supplements or replaces them is trailer restraint and dock lock repair.
Communication light fixtures. The red and green light pairs at the bay are hardware, and we cover the fixtures. The restraint controls and interlocks that drive them are on the restraint page — including the important point that published guidance notes door interlocks are sometimes put in place to help protect the dockworker from injury.
What the symptoms usually mean
| What you see | What a qualified provider may inspect | Why it matters | How to report it on the call |
|---|---|---|---|
| Seals torn or flattened | Fabric, foam, backing boards, mounting, dock face | A shot seal lets weather into the building and water onto the dock floor | "The seals are torn on 2 and 4" |
| Shelter curtain shredded or the frame loose | Head and side curtains, frame, mounting, clearance | A loose frame is a falling-object risk over a working bay | "The hood's hanging off" |
| Bumpers crushed to the steel, or missing | Remaining thickness, anchors, dock face behind | Without bumpers, the trailer reaches the dock face and the door | "The bumpers are gone on the end bay" |
| Fresh damage to the dock face or the door above | Bumper projection, dock face, door bottom, leveler frame | This is usually a bumper story with a door-repair bill attached | "Trailers are hitting the building" |
| A portable plate bent, cracked, or missing handholds | Plate condition, rating, handholds, securing method | A rated product that is damaged is out of service, not a repair candidate | "The dock plate's bent" |
| The plate slides when it is driven over | Securing method, plate condition, dock and trailer surfaces | Federal rules require it to be secured before it is driven over | "It moves when the forklift crosses it" |
| A dock light dead, or the arm broken | Fixture, arm, wiring, switch | A dark trailer is slow and unsafe to load | "The light on bay 6 is out" |
| Daylight or draught around a docked trailer | Seals, shelter, bumper projection, dock face, trailer fit | In January this is measurable money | "You can see daylight when a trailer's in" |
If something is unsafe right now: keep people and equipment clear, do not use a damaged portable plate, do not force anything, and take the bay out of service using your facility's process. That is the whole list.

What happens when you call (385) 325-7138
1. You describe it. Which bays, roughly how many, and what is worn or damaged. One call can cover several bays.
2. The details go to an independent repair company. Independent service-request website. Calls may be shared with an independent commercial dock-and-door repair company. That provider confirms availability, scope, pricing, and service terms.
3. That company confirms everything with you — address, scope, whether it can take the job, when, price, and its own contract, work and warranty terms.
If you reach voicemail, leave the facility address, the door or dock number if known, what's wrong, and a callback number.
Example wording, not a real job:
"The seals are torn on bays 2 and 4 and the bumpers are down to the steel — I can give you the address."
Call to describe the problem.
Useful on the call, but not required
Which bays. Roughly how many need work. Whether it is a seal or a shelter, if you know. What trailer mix you get. Whether anything is currently unsafe to use.
You can call without any of it. City, address and "our seals are shot" is enough. Do not go and measure anything.
What drives the price
We can't quote seal, shelter or bumper work from a web page. The price depends on how many bays, what is fitted now, the condition of the dock face, and access. Here's what to ask before you authorize work.
| What moves the price | Why | What to ask |
|---|---|---|
| The visit itself | Somebody has to see the bays | "Is there a call-out charge, and does it come off the work?" |
| How many bays | This work prices very differently in ones than in sixes | "If I do several bays at once, does the price change?" |
| Seal against shelter | Different products, different labour, different money | "Am I getting like-for-like, or is a different type a better fit here?" |
| Repairing fabric against replacing it | Patching a small tear is real. Patching a shredded curtain is not | "Is this repairable, or is it past it?" |
| Bumper type and mounting | Laminated, moulded and steel-faced bumpers differ in price and life | "What bumper are you fitting, and why that one?" |
| Dock face condition behind the bumpers | If the face is damaged, the anchors have nothing to hold | "Is the dock face itself damaged behind these?" |
| Portable plate replacement | A rated product gets replaced, not repaired | "What rating am I getting, and does it match what we run?" |
| Access, and taking bays out of service | Time on a live dock costs more | "How many bays are down at once, and for how long?" |
| Parts lead time | Seals and shelters are often made to the opening | "Is this stock or made to size?" |
And one that saves money more often than anything else on this list: "are you replacing the bumpers, or just the seals — and will new seals last if the bumpers are gone?" New fabric in front of dead bumpers is money spent twice.
Ask which kind of number you are getting — a call-out fee, a starting price, a fixed price against a written scope, an estimate, or a committed quote.
Call about one bay or all of them.
Dock equipment in a Buffalo winter
Fabric that is already torn holds water. Water freezes. Ice tears it further the next time a trailer backs in. That is the whole cycle, and it runs from November to March.
Underneath it, road salt comes in on trailer tyres and works on everything at floor level: bumper anchors, seal mounting hardware, the dock face, and the surfaces of any portable plate left outside.
And a bay with no working seal is a bay heating the parking lot. In this climate that is not an abstract efficiency argument — it is the difference between a dock you can work on in February and one you cannot.
What a provider looks at going into winter: fabric and backing condition, mounting, remaining bumper thickness, the dock face, and whether the trailer mix has changed since the seals were specified.

Questions about dock equipment in Buffalo
What's the difference between a dock seal and a dock shelter? A seal is compressible pads the trailer presses into. A shelter is a hood or curtain frame the trailer backs under. Seals give a tighter seal across a narrow range of trailer sizes; shelters handle a wider mix and leave more of the opening usable.
Our bumpers are worn through. How urgent is that? More urgent than it looks. Once the bumpers stop standing the trailer off, the trailer reaches the dock face — and then the seals, the leveler frame and the door above start taking the damage instead. Bumpers are the cheap part that protects the expensive ones.
Can a bent dock plate be straightened and put back in service? Do not assume so. A portable dockboard or dockplate is a rated product, and federal rules require it to support its maximum intended load and to be secured against moving out of a safe position. A damaged one gets taken out of use and evaluated for replacement.
Do I have to replace seals on every bay at once? No. But it is worth asking how the price changes across several bays, because mobilization is a real part of the cost and doing four at once is rarely four times doing one.
