A dock leveler is the steel ramp built into the dock edge. It rises, then lays a hinged lip onto the trailer bed so forklifts and pallet jacks can cross. People call it the dock ramp, the dock plate or just "the plate." Any of those names works on the call.

Example of what you might say: "The leveler at door 6 in our Cayce warehouse won't come up when we press the button, and I can give you the address."

Is it the leveler, or something else at the dock?

A dock leveler is built into the dock and raises a lip onto the trailer. A loose plate you carry or lift into place is a portable dock plate or dock board, and the hook that holds the trailer is a restraint.

Dock plate or installed leveler?

Federal OSHA rules group dock levelers, dock plates and bridge plates together as "dockboards" (29 CFR 1910.21(b)). They still get fixed and replaced in different ways, so it helps to know which one you have.

Blue Giant's glossary describes a dock plate as a plate with no added support members, typically used for lighter loads like foot traffic and hand trucks. It describes a dock board as a plate with beam-like side members that let it carry heavier loads such as forklifts (Blue Giant glossary). The name on the floor doesn't prove what a plate can carry. The label and the maker's paperwork do.

What kind of leveler is this?

Levelers are raised by a hydraulic pump, by springs you release with a pull chain, or by an air bag, and some stand upright when they're stored. The type tells a repair company which parts it may need.

An edge-of-dock leveler has no pit. It's a short plate mounted on the face of the dock that flips a small lip onto the trailer, so it only bridges small height differences. Go by the control you use and your records. Don't look under the deck to find out.

Names on the nameplate

Several companies make dock levelers. Rite-Hite, Blue Giant, Pioneer, McGuire and Serco are examples. We checked each one's product line on its own website on September 23, 2026. If a nameplate is easy to read from a safe spot, the maker and serial number help. You don't need them to call. A brand name doesn't mean a repair company is authorized by that maker, and Uptime isn't a dealer for any of them.

Common dock leveler problems

Leveler problems include a deck that won't come up, won't stay level, or a lip that won't come out or won't reach the trailer. Report what it's doing. A leveler normally slopes to match the trailer and can move with its height; an unexpected drop or loss of support is different. Don't push it with a forklift or stand on it to test it.

Keep people and forklifts off a leveler that isn't acting right. Follow your facility's own steps for taking the position out of use.

Know which door and what the leveler does? That's the whole report. Call it in.

A trailer is at a leveler that won't work — what now?

Stop using that position, keep people and forklifts off the leveler, and follow your facility's process for taking the bay out of use. Call (385) 325-7138, say "the dock is down," and say whether a trailer is at the door and whether it's loaded.

• Don't lift the deck with a forklift or pry at the lip.
• Don't bridge a gap with a loose plate to finish the load.
• Don't override a trailer restraint or its lights to let a trailer go.
• Do tell the company what's on the trailer and when it's due out. That helps it plan.

The independent repair company confirms availability, timing, and any charges for urgent work.

It's fair to ask whether getting the trailer out and fixing the leveler are priced as separate jobs.

Why leveler repairs are a technician's job

Levelers hold energy in springs, hydraulic pressure or air, and they carry loaded forklifts. Working on one safely means controlling that energy, and structural repairs need a qualified person.

• Stored energy. Federal OSHA's lockout/tagout rule covers servicing and maintenance where a machine could start up or release stored energy without warning (29 CFR 1910.147). In our reading, that includes powered and spring-loaded levelers.
• Structural repairs. OSHA requires structural repairs to walking and working surfaces to be done or supervised by a qualified person (29 CFR 1910.22(d)).
• After a trailer pulls out early. Copperloy's dockboard manual covers leveling devices that are structurally damaged, or that suddenly lose support under a load — as when a trailer pulls out from under them. It says they "shall be removed from service," inspected by the maker's authorized representative, and repaired before going back in service (Copperloy manual). Blue Giant's restraint manual says much the same about dock equipment that's damaged or "potentially compromised" (Blue Giant SVR303 manual).

Those are makers' words about their own equipment. The company that looks at your leveler tells you what applies to it.

Dock lifts and edge-of-dock units

A dock lift is a platform that raises loads straight up and down, often where there's no truck-height dock. Edge-of-dock units and dock lifts are covered here too. Say "dock lift" or "edge-of-dock" on the call, and describe what it's doing the same way you would for a leveler.

For a lift, mention a platform that won't rise or lower, uneven movement, a control fault, or visible damage from a safe place. Share the maker, model, rated use and load capacity if they are already on file; carrying an attendant depends on the lift's design and instructions. Ask whether the quote covers the lift mechanism and controls, replacement parts, testing and return to service. Concrete or structural work is separate and outside this line's scope.

Levelers and trailer restraints that work together

Some docks link the leveler to the trailer restraint, so the leveler only works when the trailer is held. Blue Giant describes this in its manual as an interlock that ties the leveler's sequence to the restraint. It's a product feature, not a rule every dock follows. If the leveler won't work and the restraint light looks wrong, mention both. More on restraints: trailer restraints and dock locks.

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

Covered: hydraulic, mechanical, air-powered, vertical-storing and edge-of-dock levelers, plus dock lifts, at warehouses, distribution centers, plants, cold storage, food and beverage sites and other commercial buildings. That includes lips, hinges, decks, controls and the weather seals around a leveler.

Not covered:

• Residential equipment and boat lifts
• Truck and trailer cargo doors
• Pedestrian entry doors, their locks and closers, and swinging fire doors
• Concrete pits, dock faces, slabs and other structural concrete
• Parts-only orders
• Boat docks and lake docks

Portable dock plates, dock boards, restraints, seals and bumpers are covered on the dock equipment page.

What happens when you call?

Uptime Dock & Door is an independent commercial service-request website for loading-dock and commercial door repair. You say what the leveler is doing and where the building is. The call may be shared with an independent commercial dock-and-door repair company, which confirms whether it can help, plus the scope, price, timing and its own terms.

1. You call (385) 325-7138 and say which door, what the leveler is doing, and the address.
2. Your request may be shared with an independent commercial dock-and-door repair company.
3. That company confirms the details — scope, availability, price and its own terms. Uptime doesn't do the repair, set the price or send anyone.

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

Commercial facilities are not charged by Uptime to access the public website or use its published service-request paths. For more, see how Uptime works and how dock leveler repair calls work.

You don't need the model, the capacity or a photo. Call with the door number.

Useful to have — not required

The address, the door number and what the leveler is doing are enough. These can save a question or two:

• The leveler type, from the table above
• Button or pull chain
• Whether a trailer is at the door, and whether it's loaded
• Any recent hit, or a trailer that pulled out early
• The brand and serial number, only if they're on file or easy to read from a safe spot
• Who approves the work: the tenant, the landlord or the property manager

What moves the price on a leveler repair?

We can't quote your leveler repair from a web page. The price depends on the leveler type, the fault, parts, and access. Here's what to ask before you authorize work.

Know the price words. A service-call or diagnostic fee is the charge to come look. A starting price covers a bare-bones version of the job. A scoped fixed price covers a written list of work. An estimate can move once the leveler is opened up. The final quote sets the agreed scope and price; the invoice should reflect it and any changes you approved.

Get it in writing before work starts

• What gets repaired or replaced
• Parts and labor
• Any service-call or trip charge
• Any separate concrete or pit work needed before the equipment work; concrete repairs are outside this line's scope
• The company's own warranty terms
• Who handles any permit
• For regulated construction over $10,000, the company's South Carolina contractor license number and classification

Repair or replace a dock leveler?

Parts failures — a pump, a hose, a spring, a lip cylinder — are usually repairs. Bent structure, repeat failures, a leveler that no longer fits the trucks or loads you handle, or parts that aren't made anymore push toward replacement.

A replacement leveler doesn't automatically include fixing the concrete pit. If the pit or dock face is damaged, that's separate work by a concrete or structural contractor. Ask for it to be listed on its own line.

Planned maintenance for levelers

Federal OSHA requires walking and working surfaces to be inspected regularly and as needed, and kept safe (29 CFR 1910.22(d)). The rule doesn't set a fixed schedule. South Carolina runs its own OSHA program, SC OSHA.

If you want levelers checked on a schedule, ask for these in writing:

• Which levelers are included, by door number
• What gets checked on each one
• How findings are reported, and how urgent items are flagged
• That repairs found during a visit are priced and approved separately

You can ask to have leveler checks done on the same visit as door maintenance. See commercial garage door maintenance and dock equipment maintenance.

Rules that apply to levelers here

Federal OSHA rules cover how dockboards are used, and South Carolina runs its own OSHA program. A state contractor license comes into play for regulated general or mechanical contracting when the total cost of construction is more than $10,000.

• Dockboards. They must hold the load they carry. Portable ones must be secured; §1910.26(c) allows sufficient contact to prevent unsafe movement when the employer demonstrates that securing them is not feasible. Something like wheel chocks or sand shoes must keep the trailer from moving while people are on the dockboard (29 CFR 1910.26).
• Forklifts at the dock. Truck brakes must be set, and wheel chocks or wheel blocks must be in place, while trailers are boarded, loaded or unloaded with forklifts. Dockboards must be secured before they're driven over, crossed carefully and slowly, and never loaded past their rated capacity (29 CFR 1910.178(k)(1), (m)(7) and (n)(11)).
• Powered restraints. Those sections do not require a powered restraint. Federal OSHA also recognizes equivalent mechanical protection when the restraint is installed, maintained and used as the maker directs. Vehicle/employer jurisdiction and SC OSHA requirements still matter; the facility's safety lead should confirm the applicable program, not treat any dock lock as permission to drop other precautions.
• Open edges and dockboards. OSHA 1910.28(b)(1) and (b)(4) address fall protection, with limited task-specific exceptions. Ask the facility's safety lead what applies while a bay is out of use; a door repair is not a substitute for that assessment.
• SC OSHA. South Carolina's standards page lists the federal Part 1910 general industry rules along with South Carolina's own changes.
• Industry standard. ANSI MH30.1 is the industry standard for dock leveling devices (LODEM).
• License. South Carolina requires a contractor license for regulated general or mechanical contracting when the total cost of construction is more than $10,000 (S.C. Code § 40-11-30). Check a number on the Contractor's Licensing Board lookup.
• Permits. Ask the permit office how it treats the repair, replacement and any electrical work at this address. A new hydraulic leveler also needs power to its pump and controls, so ask who does the electrical work. The permit office depends on the building's address — find yours.

These rules tell you what a qualified technician checks and why. The provider and the issuing office confirm what applies to your job.

Dock leveler questions from Columbia facility managers

Is a dock plate the same as a dock leveler? No. A leveler is built into the dock. A dock plate or dock board is portable. OSHA's rules group them together as "dockboards," but they're repaired and replaced differently.

Can we keep using a leveler that drifts down? If it drops unexpectedly or loses support, stop using it under your facility's process and call. A leveler can normally slope and follow changes in trailer height; that movement alone doesn't establish a fault.

A trailer pulled away with the lip still on it. What now? Stop using that leveler. Some makers say dock equipment that lost support under a load stays out of service until it's inspected. Call and describe exactly what happened.

Does OSHA require a trailer restraint at every leveler? Those sections do not require a powered restraint. They address brakes and chocks or blocks; federal OSHA also recognizes equivalent mechanical protection under the conditions explained above. Your facility's safety lead must match the equipment, manufacturer instructions and applicable SC OSHA requirements.

Does a replacement leveler include fixing the concrete pit? Not automatically. Pit and dock-face concrete is separate work, and this line doesn't cover it. Ask which separate concrete work must be completed before the equipment work.

Do we need the model or the capacity before calling? No. Share them if they're already in your records. Don't climb into the pit or walk under a raised deck to find them.

Do you take calls for mechanical and hydraulic levelers? Yes — hydraulic, mechanical, air-powered, vertical-storing and edge-of-dock levelers, plus dock lifts.
