Loading Dock Planning Guide: Levellers, Shelters and Seals

How to plan a loading dock: truck heights, dock levellers, shelters, seals and the doors around them.

By Zenitrix Technologies team · Updated · 5 min read

Key takeaways

Start with your trucks

List the truck and trailer types that will visit and their bed heights. The dock height and leveller range need to cover them so forklifts can cross smoothly.

Level the gap

A dock leveller bridges the gap between the truck bed and the dock floor. Hydraulic and mechanical types exist, and the right one depends on load and how often the dock is used.

Close the gap around the truck

Shelters and seals reduce dust, rain and air loss around a docked truck. Seals press against the truck, shelters form a looser frame, and inflatable or retractable types suit different trucks and climates.

Do not forget the door

A fast door on the dock opening limits air movement between loads. Plan the door, leveller and shelter together so they fit and work as one system.

Quick checklist before you decide

What to check on site

How installation usually goes

Survey and preparation

The loading bay is surveyed for dock height, door size and truck types. Equipment is fixed to prepared pits or walls, powered and tested, and the team is trained on safe operation.

How the system works day to day

A high-speed door uses a fast drive and a flexible curtain with safety sensors. A dock leveller is a ramp that bridges truck bed and floor, and shelters or seals wrap the truck rear to limit dust, rain and energy loss.

Frequently asked questions

Why use a high-speed door?

Fast opening and closing keep temperature, dust and air movement under control and speed up traffic between spaces.

What does a dock leveller do?

It bridges the gap between a truck bed and the dock floor so forklifts and pallets can cross safely, even when truck heights vary.

What is the difference between a dock shelter and a dock seal?

A dock seal presses against the truck for a tight fit. A shelter forms a looser frame around it. The right choice depends on trucks, climate and goods.

Do high-speed doors have safety sensors?

Yes. Safety sensors or edges stop or reverse the door when something is in the way. Check the type offered for your traffic.
