Why the dock door keeps getting hit, and what to install so it stops

Reviewed September 25, 2026. Official sources are linked where they exist.

Short answer

Dock doors are damaged from both sides. Inside, forklifts clip the lower track and the jambs; outside, trailers back into the wall. A goal-post guard, a steel crossbar on two posts sized to the opening, takes the forklift hits; track guards protect the lower door track; bumpers absorb the trailer. For the open door with no trailer, a dock edge safety gate closes the four-foot drop. On the compliance side, OSHA 1910.26 requires dockboards to support their intended load and, for boards placed in service after January 17, 2017, to be designed to prevent vehicles from running off the edge, and 1910.28 requires guardrail where a dockboard has a drop of 4 feet or more.

What OSHA requires at the dock

Regulation 1910.26 covers dockboards: they must be capable of supporting the maximum intended load, and those placed in service after January 17, 2017 must be designed, constructed, and maintained to prevent transfer vehicles from running off the edge. Portable dockboards must be secured and have handholds for safe handling, and the transport vehicle must be prevented from moving with wheel chocks, sand shoes, or an equivalent. Under 1910.28(b)(4), a dockboard where employees can fall 4 feet or more needs guardrails or handrails. Vehicle restraints with light communication are the standard way to prevent the trailer from moving.

Match the fix to what is being damaged.

Dock protection by what gets hit
Door tracks and jambs hit by forkliftsGoal-post guard sized to the opening, bolted to the slab inside the door
Lower track damagedBolt-down track guards
Wall and door hit by trailersLaminated or molded bumpers with projection matched to traffic
Open door, no trailerDock edge safety gate rated to stop a lift truck at low speed
Trailer creep and early departureVehicle restraint with interior and exterior lights

Questions buyers ask

Is a dock edge gate required?
OSHA requires fall protection at drops of 4 feet or more. Open-sided dock areas are guarded except at the working face; a gate is the way to guard the working face when no trailer is present.
Goal post or bollards?
A goal post protects the whole opening, jambs and header track, in one piece. Bollards protect a point. Doors that get hit across the width get the goal post.
How do I choose bumper projection?
By the trailer traffic and whether the dock has a leveler that needs the trailer at a certain distance. Standard projection covers most docks; extended projection where trailers hit hard or the wall is exposed.
