Trailer & Vehicle Restraint Repair in Orlando, FL
For trailer restraint repair in Orlando, FL, call (385) 325-7138 about a dock lock that won't hook, won't let go, or shows the wrong signal light. A trailer restraint — also called a vehicle restraint, truck restraint or dock lock — is a device on the building that holds a parked trailer at the dock so it can't roll or pull away while forklifts work inside it.
Call to describe the problem—if the door is stuck open or the dock is down, say so first.

Is this the right page?

Which restraint do you have?
You don't need to know the type to call. If you do know it, it helps.
| Type | How it works, in plain words | What to mention on the call |
|---|---|---|
| Hook restraint | A steel hook rises from a unit on the dock wall and grabs the bar under the back of the trailer (the rear impact guard) | "The hook won't come up" or "it won't let go" |
| Wheel restraint | A unit at ground level blocks a trailer wheel | "The wheel block won't move" |
| Manual restraint | A worker moves it into place by hand or with a lever | "It's stuck and won't move by hand" |
| Powered restraint | It runs from a control panel inside the dock | "The button does nothing" or "it stops partway" |
Rite-Hite lists vehicle restraints among its products, including its Dok-Lok line (Rite-Hite). The brand helps describe it, but it doesn't say who installed it. You can call without it.
Signal lights and interlocks
Most powered restraints come with signal lights. Usually one set faces the driver outside and one faces the dock crew inside. Colors change to show whether the trailer is held. Some docks also have interlocks — controls that won't let the door open or the leveler run until the restraint is engaged.
When the lights don't match what's happening, that's a real problem. People may trust a light that's wrong. Report exactly what you see: which light, what color, and whether the restraint looks engaged. Don't override, bypass or reset the controls to get the dock running. That's for a trained technician.
What's the restraint doing?
Say what you see from inside the dock or from a safe spot outside. Don't reach under the trailer or into the restraint.
| What you're seeing | What a qualified provider may inspect | Why it matters | How to report it |
|---|---|---|---|
| It won't engage or hook | Hook or arm, motor or hydraulics, controls | The trailer may not be held | "The restraint at dock 5 won't hook." |
| It engages, but the trailer still moves | Hook fit, the trailer's rear bar, the unit's mounting | The trailer can creep away from the dock | "It's hooked, but the trailer still shifts." |
| It won't let go of the trailer | Hook, motor, controls | The trailer can't leave, and a driver is waiting | "It won't release the trailer." |
| The inside light is stuck on red or green | Sensors, lights, control panel | Workers may trust a wrong signal | "The inside light stays red." |
| The outside light is wrong | Lights, sensors, wiring | Drivers may pull out at the wrong time | "The driver's light is green while we're loading." |
| An alarm keeps sounding | Sensors and controls | Something doesn't match | "The alarm won't stop at dock 5." |
| It's stuck up or stuck down | Motor, hydraulics, the unit itself | The dock may be out of use | "It's stuck in the up position." |
| It was hit by a trailer | Mounting, hook, housing, wiring | A damaged unit may not hold | "A trailer backed into it." |
| The door or leveler won't run because of the restraint | Interlock wiring and controls | The dock is stopped | "The door won't open unless the restraint is on." |
Something like this going on? Call and describe it the way you'd tell a coworker.
A trailer is stuck at the dock, or can't be secured
Say so first when you call. Keep people out of the trailer and off the dock plate or leveler until the restraint is sorted out. Follow your facility's own process for securing trailers — many sites use wheel chocks — while the restraint is out of service. If the restraint won't release and a driver is waiting, say that too.
If it happens at night or on a weekend, there may be no one at the warehouse to meet a technician. Tell the provider who can meet them at the dock.
Example wording, not a real job: "The trailer restraint at dock 5 won't let go of the trailer, at our warehouse in Orlando, and the driver is waiting."
If the dock is down, say so first.
What does OSHA actually say about restraints?
OSHA's rules name wheel chocks as one way to keep a trailer from moving. They don't require a powered restraint. Florida isn't an OSHA State Plan state, so federal OSHA covers most private employers here (OSHA State Plans).
- Dockboard rule: "Measures, such as wheel chocks or sand shoes, are used to prevent the transport vehicle from moving while employees are on the dockboard" (29 CFR 1910.26).
- Forklift rule: "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" (29 CFR 1910.178).
The industry standard for restraints is ANSI MH30.3-2022, "Performance and Testing of Vehicle Restraining Devices" (ANSI). It's a voluntary standard, not a law.
You may hear that OSHA requires every trailer to be held by a chock or a restraint. The rule text above is narrower than that. Your safety team decides how your docks meet it.
For more on how restraints and chocks compare, see the national guide to vehicle restraints vs. wheel chocks.

What changes the price?
We can't quote a restraint repair from a web page. The price depends on the restraint type, the part that failed, parts, and access. Here's what to ask before you authorize work.
| What drives the cost | Why it moves the price | What to ask |
|---|---|---|
| Service call or diagnostic charge | Many companies charge to come out | "Does it count toward the repair?" |
| Restraint type | Hook and wheel restraints use different parts | "What type is this?" |
| The failed part | A motor, hydraulic part, sensor or control board each costs differently | "Which part failed?" |
| Lights and interlocks | Sensors and wiring may need an electrician | "Is the electrical work included?" |
| Impact damage | A unit hit by a trailer may need a new housing or remounting | "Repair or replace?" |
| Parts and lead time | Some brands need special-order parts | "How long for parts?" |
| After-hours visit, if offered | A trailer stuck at night may mean off-hours work | "Is after-hours pricing different?" |
| Several docks at once | One visit for several restraints | "Is the price per dock?" |
Florida law says a contractor "shall subcontract all electrical" work unless it holds the state electrical license (s. 489.113). Ask who handles any wiring.

Planned maintenance for restraints
Restraints work hard and get hit by trailers. A scheduled check can catch a weak hook, a failing sensor or a light that doesn't match before it causes a problem. Ask for a written report for each dock: what was checked, what was adjusted, what needs repair, and how soon.
Call about planned maintenance for your dock restraints.

Questions about trailer restraint repair in Orlando
Does OSHA require a trailer restraint?
OSHA's rules name wheel chocks as one way to keep a trailer from moving while it's loaded. They don't require a powered restraint. Many docks use restraints anyway, and the restraint standard is ANSI MH30.3-2022, a voluntary industry standard.
Why is our dock restraint light stuck on red?
Often a sensor, the control panel, or the restraint itself isn't reading right. A technician checks the lights, sensors and controls. Don't override or bypass them to get the dock moving.
The restraint won't let go of the trailer. What should we do?
Keep people clear and don't force it or try to release it by hand. Call and say the trailer is stuck and whether a driver is waiting. Tell the provider who can meet them at the dock.
Is a restraint that won't engage an emergency?
It means the trailer may not be held, which is a safety problem. Keep people out of the trailer, follow your facility's process for securing trailers, and call. Say "the dock is down" first.
Do you fix the bar on the back of the trailer?
No. The rear bar is part of the trailer, and trailer repairs go to a trailer shop. This line handles the restraint on the building.
