Dock-High Loading
A loading configuration where the warehouse floor is elevated to match semi-trailer bed height (48-52 inches), enabling direct forklift access to trucks.
Definition
Dock-high loading means the building floor is raised approximately 48-52 inches above grade to align with semi-trailer beds. This allows forklifts to drive directly from the warehouse into trailers for efficient loading and unloading of palletized goods. Dock-high facilities use dock doors, levelers, and bumpers to bridge the gap between building and trailer. This configuration is standard for distribution, wholesale, and manufacturing operations that receive or ship via semi-trucks. In contrast, grade-level loading (floor at ground level with roll-up doors) suits businesses using vans, box trucks, or that need to drive vehicles inside. Small bay properties are predominantly grade-level, while larger industrial facilities are typically dock-high.
Example
A wholesale distributor receives palletized inventory via semi-trucks twice weekly. They require dock-high loading so forklifts can quickly unload trailers. A small bay flex unit with only grade-level roll-up doors wouldn't work—they'd need to hand-unload or rent lift equipment for each delivery.
