Which dock equipment is this?

Loading docks have a lot of equipment around the door and leveler. This page covers the parts that seal the trailer, protect the dock and hold the trailer in place. Levelers, dock plates and dock boards are on the dock leveler repair page. The dock door itself is on commercial overhead door repair.

Dock seals and shelters

A dock seal and a dock shelter both close the gap between the building and the trailer. A seal uses foam pads that press against the trailer. A shelter uses a frame with fabric curtains that the trailer backs into. Both wear out from trailer contact. When they tear or flatten, heat, cold, rain and pests get in.

What a qualified provider may look at:

Torn fabric or foam that's worn through
Pads or curtains that have pulled loose from the frame
A bent shelter frame after a trailer hit it
Whether the seal or shelter still fits the trailers you use

Repair or replace? Sometimes new fabric or pads are enough. A bent frame or a seal that no longer fits your trailers may need a full replacement. Ask whether the price covers mounting and any wall repair behind it.

Dock bumpers

Dock bumpers are the blocks on the dock face that trailers back into. They take the impact so the building and the leveler don't. When bumpers are worn thin, cracked or missing, the trailer hits the dock wall or the leveler's edge instead.

What a qualified provider may look at:

How worn the bumpers are
Whether the mounting bolts and plates are still solid
Whether the wall or leveler behind them was damaged

Concrete repair on the dock face isn't covered. If the wall behind the bumper is cracked, mention it. The provider can tell you whether it affects the bumper job.

Vehicle restraints and dock locks

A vehicle restraint holds a trailer at the dock so it can't pull away or creep while people and forklifts are inside it. It's also called a trailer restraint, truck restraint or dock lock. Most are either a hook that grabs the trailer's rear bumper bar or a device that blocks the wheels. Most restraints come with red and green lights, and some are tied to the leveler or the door.

Types of restraints

Type	How it works	Common complaints	What to report
Rear-bar (hook) restraint	A hook rises to grab the trailer's rear impact guard, the bar under the back of the trailer	Won't grab, won't let go, hook damaged	"Hook won't come up" or "won't release"
Wheel-based restraint	A device blocks one of the trailer's wheels	Won't engage, won't retract	"Wheel restraint won't retract"
Manual restraint	Worked by hand at the dock	Stiff, bent, won't lock	"Hard to lock"
Wheel chocks	Wedges set at the wheels by hand or on a chain	Missing, damaged	"Chock at bay 4 is broken"

What to report

Won't grab. Say whether a trailer is at the dock and what the lights show.
Won't let go. Say the trailer can't leave. Don't pry, force or override the restraint. Tell the driver it's being reported.
Lights disagree with what you see. Say both: what the lights show inside and outside, and what the restraint is actually doing. Don't assume the trailer is held.
Damaged after an impact. Say what you can see from a safe spot.

Restraints, levelers and doors are sometimes wired together so one can't run unless another is set. If more than one is acting up, say so. Don't bypass an interlock.

What the rules say

ANSI MH30.3 is the industry standard for vehicle restraining devices (MHI LODEM). OSHA's dockboard rule says employers must use measures, "such as wheel chocks or sand shoes," to keep the truck or trailer from moving while employees are on the dockboard (29 CFR 1910.26(d)). The forklift rule says a highway truck's brakes must be set and its rear wheels chocked while it's boarded by a forklift (29 CFR 1910.178(k)(1)). Neither rule names a powered restraint specifically. Your facility's own loading process decides how trailers are secured.

Our guide on vehicle restraints vs. wheel chocks goes deeper.

Dock lights and communication lights

Dock lights shine into the trailer so the crew can see. Communication lights tell the driver and the dock crew when it's safe to back in, load or pull away. Communication lights are often part of the restraint system.

Report what you see. Is a light out? Stuck on one color? Do the inside and outside lights disagree? Is it the light itself, or the arm it hangs on? Wiring falls under the Alabama Electrical Contractors Board. See local checks.

Emergency: a trailer is stuck or not held

If a restraint won't let a trailer go, or won't hold one, call (385) 325-7138 and say the dock is down. Keep people out of the trailer if it may not be held. Use your facility's own process to take the bay out of use. Don't pry, force or override the restraint. We don't promise dispatch or response times. The company that takes the job confirms timing.

For example, you might say: "The restraint at dock 7 in our Huntsville DC won't release the trailer, and the lights are stuck on red."

If the dock is down, say so first.

What affects cost?

We can't quote your dock equipment 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 price	Why it changes things	Ask before you say yes
Trip or diagnostic charge	Many companies charge to come look	"Is there a trip charge?"
Seal or shelter design	Pads, curtains and frames differ; some are made to fit	"Can you replace just the fabric or pads?"
Bumper type and mounting	Rubber vs. steel-faced; bolts and plates	"Is mounting included?"
Restraint type	Hook, wheel and manual restraints use different parts	"What failed?"
Controls and wiring	Lights and interlocks need a licensed electrician	"Who does the electrical work?"
Number of bays	Several bays can sometimes be done in one visit	"Is there a price for all the bays?"
Access while the dock is busy	Work may need the bay closed	"How long will the bay be out?"

Ask whether you're getting a diagnostic fee, a starting price, an estimate or a quote for a set scope, and what's included.

Ask what the price covers, then call.

Planned dock-equipment service

Planned service is a scheduled visit to check seals, shelters, bumpers, restraints and lights before they fail. It's not a repair call. Ask the provider what the visit covers, how often it suggests visits for your traffic, and what written record you get. For doors, see commercial garage door maintenance. For levelers, see planned leveler service.

Local checks in Huntsville

Electrical work. Restraint controls, lights and interlocks fall under the Alabama Electrical Contractors Board. Ask who does the wiring.
State license. A general contractor license is required for covered work of $100,000 or more. Starting October 1, 2026, certain routine or regular maintenance and repair work may qualify for an exemption; the Board handles questions about specific projects (Board notice).

Questions about dock equipment

Should I repair or replace a torn dock seal?

It depends on how much is torn and whether the seal still fits your trailers. Sometimes new pads or fabric are enough. The company that looks at it will tell you.

What should I do if a trailer restraint won't release?

Say "the dock is down" and call. Tell the driver it's being reported. Don't pry, force or override the restraint.

Are vehicle restraints required by OSHA?

OSHA's rules call for measures such as wheel chocks or sand shoes to keep a trailer from moving, and for chocks and set brakes when a forklift boards a truck. They don't name a powered restraint specifically. Your facility's process decides what you use.

How do I know when dock bumpers need replacing?

When they're cracked, worn thin or missing, or when trailers are hitting the wall or the leveler edge. Mention any wall damage too.

Can the dock lights be fixed without replacing the restraint?

Often. It depends on whether the problem is the light, its wiring or the restraint's controls. Describe what you see and the company will check.
