What's the equipment around your dock door called?

Most equipment around the dock opening that isn't the door or the leveler is covered on this page: seals and shelters around the opening, bumpers on the dock wall, portable plates and boards, trailer restraints and their lights, and dock lights. If you don't know the name, match what you see.

Brands you might see include Rite-Hite, Blue Giant, Kelley, Serco, or McGuire. Mention one only if you already know it or can read it from a safe spot.

For levelers, see dock leveler repair. For the doors, see overhead door repair or roll-up door repair.

Dock seals and shelters

A dock seal is a set of padded foam pads that press against the back of the trailer. A dock shelter is a frame with fabric curtains that the trailer backs into. Both close the gap between the building and the trailer. When they're torn or crushed, weather and outside air get in.

Worn pads or curtains may be replaceable without a whole new unit. It depends on the frame and how old the unit is. Ask the provider to explain the choice.

Dock bumpers

Dock bumpers are the blocks on the dock wall that take the hit when a trailer backs in. When they crack, wear through, or fall off, the trailer hits the building instead.

• What to mention: which dock, cracked or missing, and whether the wall behind looks damaged.
• What to ask: whether the bumpers can be replaced and whether the anchors are sound.
• Where the line is: concrete or dock face repair is a different kind of job and isn't covered here.

Dock plates and dock boards — repair or replace?

A dock plate or dock board — sometimes called a bridge plate — is a portable bridge laid between the dock and the trailer. If one is bent, cracked, has a damaged weld, or has a damaged leg or locking pin, take it out of use and have it checked. Don't weld it, flip it over, or put it back under a forklift until a qualified provider says it's safe.

Plate or board?

Manufacturers generally describe dock plates as lighter pieces for hand trucks and carts, and dock boards as heavier pieces, many built for forklifts. The capacity marking on it, or your equipment records, tells you what it's rated for. ANSI MH30.2 covers these portable dock loading devices.

Signs a plate or board should come out of use

If you notice any of these in normal use:

• It's bent or bowed.
• There's a crack, or a weld looks broken.
• A leg or locking pin is bent, loose, or missing.
• The capacity marking is gone, so no one knows what it can hold.
• It doesn't reach far enough or rocks when set down.
• It slides when it's supposed to stay put.

What federal rules say

Federal rules call dock plates and dock boards "dockboards" (29 CFR 1910.21(b)). A dockboard must be able to hold the load it carries, and portable ones must be secured so they don't slide (29 CFR 1910.26). The fall-protection rule lets a dockboard go without guardrails only when it's used solely with motorized equipment and the rule's other conditions are met (29 CFR 1910.28(b)(4)).

Repair or replace?

Trailer restraints and dock locks

A vehicle restraint, also called a trailer restraint, truck restraint, or dock lock, limits trailer movement while a forklift works inside. Many engage the rear impact guard; others engage a wheel (MHI's vehicle-restraint definitions). Red and green lights communicate restraint status to the driver and forklift operator; they aren't a substitute for the facility's loading checks. If it won't engage or the lights are wrong, follow your facility's process for taking that dock out of use, and call.

Common problems to report

• Won't engage or won't grab the bar
• Won't release
• Lights stuck on red or green, or showing the wrong color
• An alarm sounding
• The hook or arm bent after a trailer hit it

Don't try to bypass, override, or reset a restraint. Tell the provider exactly what the lights show.

Is a restraint required?

Federal rules require the truck's brakes to be set and wheel chocks placed when forklifts drive onto it (29 CFR 1910.178(k)(1)). Under its directive STD 01-11-007, OSHA accepts a vehicle restraint instead of chocks on three conditions:

1. It actually keeps the trailer from moving.
2. It's installed, maintained, and used the way the manufacturer says.
3. Damaged equipment is taken out of service right away.

OSHA doesn't require a powered restraint. Your facility's own policy may still require chocks and a restraint together. The industry standard for vehicle restraints is ANSI MH30.3.

That third condition is why a broken restraint matters. If a restraint is used in place of chocks, OSHA's directive expects damaged equipment to come out of service. Follow your facility's process.

Interlocks and lights

Some docks tie the restraint to the door or the leveler, so one won't run until the other is set. If your dock works that way, tell the provider. Never override an interlock to keep loading.

If the dock lock isn't working, follow your facility's process for taking that dock out of use. Then call and say what the lights show.

Call(385) 325-7138

Dock lights and wheel chocks

• Dock lights light the inside of the trailer. Broken arms, dead lights, and damaged wiring get repaired or replaced. Ask whether the job involves electrical work (see the license rules below).
• Wheel chocks get replaced when cracked, split, or missing. Federal rules require chocks when forklifts drive onto a truck, unless a working restraint is used under OSHA's directive, as explained above.

What does this cover, and what doesn't it?

Covered: dock seals, dock shelters, dock bumpers, dock plates, dock boards, trailer and vehicle restraints, communication lights (the red and green signals for drivers and forklift operators), dock lights, and wheel chocks. At warehouses, distribution centers, plants, cold storage, food and beverage buildings, and other commercial loading docks.

Not covered:

• Truck and trailer repair
• Concrete dock face, pit, or slab repair
• Parts-only orders
• Boat docks ("dock" here means a loading dock)

If your equipment is on the covered list, the next step is a call.

What does dock equipment repair cost?

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

Ask which kind of number you're getting: a trip or diagnostic charge, a starting price, an estimate, or a fixed quote for a written scope. Ask what it includes.

Frequently asked questions

Can a bent dock plate be straightened or welded?

Take it out of use first. A qualified provider decides whether it can be repaired safely. Bent or cracked plates may need to be replaced.

Do I still need wheel chocks if I have a dock lock?

OSHA accepts a working restraint instead of chocks under three conditions in its directive STD 01-11-007. Your facility's policy may still require both.

Why are my dock lock lights stuck on red?

It could be a sensor, the restraint itself, or the controls. Follow your facility's process for taking that dock out of use, and call. Don't override it.

Can torn dock seal pads be replaced without a new seal?

It may be possible. It depends on the frame and how old the unit is.

Is a dock plate the same as a dock leveler?

No. A leveler is built into the dock. A plate is a loose piece laid on the trailer. See dock leveler repair.
