Protecting Overhead Dock Doors from Forklift Impacts

Dock door with overhead door protection system

Walk around any warehouse, manufacturing facility, or commercial storage operation of any size, you’ll almost always find two things — forklifts and dock doors. If that building has been in place for any substantial length of time, you’ll also find dinged, dented, ruined or replaced dock door guides, pallet rack frames, building columns, etc. It just happens that way. While many operations take steps to use guard rails or bollards to shield their critical machinery, dock doors can be left out.

Anyone who’s ever experienced a door frame (or a door itself) being impacted knows the hassle that brings. It can cause you to be unable to operate the door until repairs can be made, which are costly and can crimp operations for hours, or longer.

There are a several ways to go when it comes to protecting your doors, and the best way depends on your door setup, the kind of door you have, and the space around your door.

  • For tight spaces, overhead door track protectors are ideal. They shield either 2′ or 3′ of the door track at the base – which is the most frequently-forklift-impacted part of a dock door. People backing lift trucks up hit them all the time. Even a relatively minor impact from a walkie or stacker (and a sufficiently loaded, moving pallet jack) can damage a door frame. Easily the most economical way, door tracks can cost about $100 a pair (give or take). They don’t take any space up around the door frame either, so if space for package stacking or a shop desk is needed they leave you plenty of area for that.
  • More inclusive and protective are “Goal Post” Dock Door Guards. They enclose the entirety of a dock door. If you have an expensive high speed door apparatus, and people are driving lift trucks with forks up into or out of the door (like they can do in a freezer, shipping, or internal door application) this system protects the entire height of the tracks, but also any apparatus above the door. They’re more expensive than simple track guards (by a good bit) but they can help you protect almost any kind of opening, including the walls around a door, from forklift damage. Since they can be customized to extend to the left or right of a door, they can even protect control panels or other equipment on any side of the door.
  • You can also opt for Steel Guard Rails. Installed between doors, but covering the base of a track, they shield the base about as well as track protectors. They completely occupy that space, but also can be offset to allow stacking or other functions on the wall areas between doors. They are more expensive than track guards, but offer extended protection to walls between door bays.
