Loading dock repair

What a dock repair company covers

• Dock doors. Sectional and rolling doors, springs, tracks and operators.
• Dock levelers. Mechanical, hydraulic and air-powered. See dock leveler repair.
• Dock seals and shelters. Torn fabric and crushed foam that let weather in.
• Vehicle restraints and wheel chocks. Hooks that won't engage or release.
• Dock bumpers. Worn or missing bumpers lead to wall and trailer damage.
• Dock lights and communication lights.

Planned maintenance

Most dock equipment failures show warning signs first. A planned maintenance visit once or twice a year costs far less than an emergency call and a closed dock position. Our maintenance checklist shows what to look for between visits.

Signs a dock position needs attention

• Daylight, rain or wind coming in around a trailer backed onto the dock.
• A leveler that is slow, noisy, or sits uneven when stored.
• Forklifts bumping or jolting as they cross onto trailers.
• Trailers creeping away from the dock during loading.
• Bumpers worn down to the steel, or chipped concrete on the dock face.
• Restraint lights that don't match what the restraint is doing.
• A dock door that staff avoid because it is hard to open.

Any one of these is worth a look. Several together mean the position is overdue for service.

Dock seals and shelters

Dock seals are foam pads covered in fabric that the trailer presses into. They seal tightly and suit docks that see trailers of similar size. The fabric wears where trailers rub, and the foam crushes over time.

Dock shelters are frames with fabric curtains that close around the trailer. They fit a wider range of trailer sizes and give full access to the trailer opening, but seal less tightly. Curtains tear and stays bend.

Torn fabric and crushed foam can often be repaired or re-covered without replacing the whole unit. In a heated, cooled or food-grade building, a failed seal costs money every day in energy and can let in pests and water.

Vehicle restraints

A vehicle restraint holds the trailer to the dock by its rear impact guard, so it cannot creep forward or pull away while a forklift is inside. Most have red and green lights inside and out to tell the forklift driver and the truck driver when it is safe.

Common faults are a hook that won't raise or release, damaged housings from trailer impact, failed lights and worn sensors. A restraint that shows green when it hasn't engaged is a serious hazard and should be reported and repaired at once.

Bumpers

Dock bumpers absorb the force of a trailer backing in. Once they wear through, that force goes into the building wall, the leveler and the trailer itself. They are among the cheapest items on a dock to replace and among the most often ignored. Laminated rubber, molded rubber and steel-faced bumpers are available for different traffic levels.

What a planned maintenance program covers

• Doors: springs, cables, rollers, tracks, operators and safety devices checked and lubricated.
• Levelers: pits cleaned, hinges lubricated, hold-downs or hydraulics checked.
• Restraints: operation, lights and sensors tested.
• Seals, shelters and bumpers inspected.
• A written report for each dock position, with repairs listed by urgency.

The report matters as much as the visit. It lets you budget repairs before they become emergency calls, and it is a record that equipment has been inspected.

The cost of a dock position being down

A dock position out of service means trucks waiting, loads moved to other doors and staff working around the problem. When you compare a repair quote with the price of doing nothing, include the hours of lost loading and any detention charges from carriers kept waiting.
