How We Handle It

How We Handle Vehicle Restraints

You Need a Restraint System

A new dock position has no restraint. An old one is stuck, cracked, or won’t engage the trailer’s rear impact guard. Either way, product and people are at risk during loading.

You Call Kodiak

Live dispatch available. We ask whether you need a quote for new equipment, an installation, or a repair on what’s already there.

Technician or Quote Arrives

For repairs, our trucks carry hydraulic pumps, hook assemblies, control panels, and hardware for same-visit fixes. For new installs, we walk the dock, confirm restraint type, and quote the job on the spot.

Trailer Secured, Verified Under Load

Full engagement test on the rear impact guard, interlock check with the dock leveler where applicable, and a safety walkthrough before we leave.

Why Kodiak

Why Kodiak for Vehicle Restraints

Our Services

Types of Vehicle Restraints We Sell, Install & Service

Hydraulic Vehicle Restraints

Hydraulic Vehicle Restraints

A hydraulic arm finds a trailer's rear impact guard (RIG) and locks onto it, holding continuous pressure for the length of the loading cycle. Kodiak installs and services Poweramp's hydraulic restraints, which locate the RIG automatically and apply firm, continuous pressure once engaged.

Request Service
Automatic (Non-Impact) Vehicle Restraints

Automatic (Non-Impact) Vehicle Restraints

One button secures the trailer — no driver or dock worker has to line anything up by hand. Kodiak installs Poweramp's non-impact restraints, which mount to a concrete drive approach or building foundation without cutting into the dock structure.

Request Service
Manual Vehicle Restraints

Manual Vehicle Restraints

For docks with lighter, more predictable trailer traffic, a manual restraint costs less upfront and does the job. Kodiak installs Poweramp's manual restraint line, built for standard shipping and receiving docks.

Request Service
Truck-Positioned Restraints (TPR)

Truck-Positioned Restraints (TPR)

Rather than mounting to the dock face, a TPR mounts to the trailer itself, positioning and securing the rear impact guard automatically. That cuts the risk of premature trailer separation during loading and unloading — a common fit for facilities that rotate trailers through the same dock positions all day. Kodiak installs and services Poweramp's TPR line for exactly this kind of high-turnover dock.

Request Service
Wheel-Based Restraint Systems

Wheel-Based Restraint Systems

Instead of engaging the rear impact guard, a wheel-based restraint locks the trailer's rear wheels in place. It's a common choice where RIG height or condition varies across a facility's trailer mix, or where a driver needs to see the restraint engage from the cab.

About Our Service

About Our Vehicle Restraint Service

Kodiak’s technicians have installed and repaired vehicle restraints for over 35 years. We know which hook mechanisms wear out fastest on high-cycle docks, which hydraulic seals need replacing before they leak, and how to wire a restraint-to-leveler interlock so the leveler can’t be lowered until the trailer is actually secured.

We sell, install, and service vehicle restraints at warehouses, distribution centers, manufacturing plants, and commercial facilities across Missouri and Illinois.

Kodiak works with Poweramp vehicle restraint systems and services all major restraint brands, including Rite-Hite, Kelley, Serco, McGuire, APS, and Blue Giant. For Poweramp equipment details, review the PowerHold hydraulic restraint, PowerHook automatic restraint, PowerStop Automatic, PowerStop Manual, and TPR truck-positioned restraint product PDFs.

Kodiak’s vehicle restraint maintenance covers hook or hydraulic arm inspection, hydraulic pump pressure testing, control panel checks, interlock wiring checks, warning light testing, mounting hardware inspection, and full engagement and release cycle testing.

Most facilities benefit from semi-annual restraint inspections. High-cycle distribution docks should inspect quarterly.

Vehicle Restraint Maintenance

A vehicle restraint sees a hard cycle every time a trailer pulls in or out, and a busy dock position can run through dozens of cycles a day. A hook mechanism or hydraulic seal that looks fine today can fail the next time a driver backs in too fast.

Industries

Industries That Depend on Vehicle Restraints

Warehouses & Distribution Centers

High-cycle docks run dozens of trailer changes a day, and every one depends on the restraint holding through the full loading cycle. Kodiak keeps high-traffic restraints running and installs new units sized to match your trailer turnover.

Manufacturing & Assembly Plants

Raw material and finished goods trailers load and unload at the same dock positions all shift long. Kodiak services restraints where a failed unit stops a production line’s inbound or outbound flow.

Food & Beverage Facilities

Cold chain and food-grade docks need restraints that hold up to washdown and temperature cycling without corroding. Kodiak installs and services restraints built for sanitation-focused facilities.

Third-Party Logistics (3PL)

3PL operations run multiple shifts with trailers from different carriers cycling through constantly. Kodiak provides restraint maintenance programs and emergency repair for 3PL docks across Missouri and Illinois.

Retail Distribution

Retail DCs run tight receiving schedules during peak season, and a restraint that won’t engage stalls the whole inbound line. Kodiak dispatches for emergency restraint repair when a dock position goes down.

Cold Storage & Refrigerated Warehouses

Cold storage docks put restraints through temperature swings and condensation that accelerate corrosion. Kodiak services restraints at refrigerated and frozen facilities where standard hardware wears out faster.

Automotive & Heavy Industrial

Heavy trailers and frequent backing accidents put more stress on a restraint’s hook or hydraulic arm. Kodiak installs restraints rated for the higher impact and load demands of automotive and industrial docks.

Building Materials & Construction Supply

Flatbed and open-trailer deliveries common to lumber yards and building material suppliers need restraints that engage reliably even with irregular rear impact guard placement. Kodiak fits restraint type to the trailer mix your dock actually sees.
Troubleshooting

Common Vehicle Restraint Problems & Kodiak Fixes

1. Restraint Won't Engage the Trailer

Cause: On hydraulic and automatic units, a failed pump, low fluid, or a hook mechanism that’s bent or worn. On manual units, a seized lever or corroded pivot point. Kodiak fix: Test the hydraulic system or manual mechanism, identify the failed part, and replace it. Our trucks carry pumps, hooks, and hardware for same-visit repairs on most brands.

2. Restraint Engages but Won't Hold Under Load

Cause: Worn hook teeth that no longer grip the rear impact guard fully. A hydraulic system that loses pressure under sustained load. A mounting foundation that’s cracked or shifted. Kodiak fix: Replace the hook assembly or rebuild the hydraulic cylinder. We check the mounting foundation and anchor bolts while the unit is apart.

3. Restraint Won't Release

Cause: Control panel fault, jammed release mechanism, or a hook that’s bent just enough to catch on release. Kodiak fix: Diagnose the control circuit and free or replace the release mechanism. We verify full release before clearing the dock for the next trailer.

4. Warning Lights Don't Match Actual Restraint Status

Cause: Failed sensor, damaged wiring, or a control panel that’s lost its interlock connection to the dock leveler. Kodiak fix: Trace and repair the sensor and wiring, then re-verify the leveler interlock so the dock can’t be raised until the restraint confirms engagement.

5. Restraint Corroding or Rusting Through

Cause: Washdown chemicals, road salt tracked in on trailer tires, or moisture exposure at outdoor-facing docks. Kodiak fix: Replace corroded hardware with stainless or coated components rated for the facility’s environment. We assess whether the base unit still has structural integrity before recommending hardware-only repair.

6. Restraint Doesn't Fit the Trailer Mix

Cause: A hook-style restraint installed at a dock that now receives trailers with damaged, low, or non-standard rear impact guards, or wheel positions that vary too much for a wheel-based unit. Kodiak fix: Assess the actual trailer mix and recommend the restraint type built for it, hydraulic, automatic, manual, or wheel-based.

Great company to work with, I've been using them for 10 years now and have no complaints. They are a good company to get on your team and can think out of the box on custom solutions or oddball repairs. I've used them for mobile welding, overhead door cut ins, dock leveler cut ins, and general maintenance. -Chuck

Common Questions

Vehicle Restraint FAQ

We sell and install hydraulic restraints, automatic (non-impact) restraints, manual restraints, truck-positioned restraints (TPR), and wheel-based restraint systems. We work with Poweramp, Rite-Hite, Kelley, Serco, McGuire, APS, and Blue Giant.

We dispatch from our shop in Barnhart, MO. A technician may be able to arrive within 2 to 4 hours for facilities in the St. Louis metro area. For locations in Springfield, Jefferson City, or the Metro East, response times vary by distance.

A new manual restraint typically installs for $1,500 to $3,000. Automatic and hydraulic restraints run $3,000 to $6,000 installed, depending on the model and dock condition. Repair costs depend on what failed, a hook replacement is a different job than a full hydraulic pump rebuild. We provide an upfront quote before starting any work.

Both use a powered mechanism to lock onto the trailer's rear impact guard without requiring the driver to line anything up. Hydraulic restraints hold continuous pressure through the hydraulic system for the full loading cycle. Automatic restraints, like a hook-style unit, engage and lock in one motion at the push of a button. Most high-traffic commercial docks use one of these two types over manual restraints.

Wheel chocks alone don't prevent premature trailer separation, the trailer pulling away from the dock while a forklift is still on the trailer bed. A restraint engages the rear impact guard or wheels in a way that resists that pull-away force. Wheel chocks are a supplement to a proper restraint system, not a replacement for one.

It should. An interlocked system prevents the dock leveler from being lowered onto the trailer bed until the restraint confirms the trailer is secured, and prevents the restraint from releasing while the leveler is still deployed. Kodiak checks and wires this interlock on every restraint we install or service.

Semi-annually for standard commercial docks. Quarterly for high-cycle distribution docks running dozens of trailer changes a day. Regular inspection catches hook wear, hydraulic leaks, and interlock wiring faults before they cause a dock shutdown.

Most restraint problems, hook wear, hydraulic pump failure, control panel faults, corroded hardware, are repairable. Replacement makes more sense when the mounting foundation is cracked, the restraint no longer matches your trailer mix, or repair costs exceed 50-60% of a new unit.

A wheel-based restraint locks a trailer's rear wheels instead of engaging the rear impact guard. It works well for docks that see trailers with damaged, low, or non-standard RIGs, since it doesn't depend on the guard's condition. Kodiak installs wheel-based restraints as an alternative to hook and hydraulic-style units.

Yes. We offer scheduled maintenance programs for vehicle restraints, semi-annual for standard facilities, quarterly for high-cycle operations. Each visit includes hook or hydraulic arm inspection, control panel and interlock testing, warning light checks, and a full engagement test under load. Maintenance contracts reduce emergency calls and extend the working life of the equipment.
