Trailer Height Adjustments

Show your loading dock who’s boss with a posse of truck and trailer wheel risers, levelers, and pit fillers that salvage the capabilities of unproductive, unsafe loading docks. Our custom-configured loading dock systems triage trailer issues with compound decline approaches, inferior drainage placement, and other design blunders to avoid needing a loading dock equipment overhaul.  Beware of catalog or homemade solutions as they often fall short of resolving your loading dock issues.

Loading and unloading trailers above the building floor level minimizes interferences by the bumpers and building face. It reduces product damage and allows forklift drivers to have a better grade in and out of trailers.

 

Wheel Risers, also known as Truck or Trailer Risers, must be designed based on a customer’s specific loading dock conditions and trailer requirements..We review existing length and width of the platforms, dock slope, and drainage to deliver a solution.  

 

Loading Dock Pit Fillers are custom wheel risers that are built to eliminate trailer height changes caused by sloped driveways. When loading dock concrete construction places drainage several feet from the building, this causes the trailer bed height to come in lower than on a level dock approach.  Pit Fillers maintain drainage for the dock and bring the trailer bed at or above dock, regardless of the trailer axle’s position.

 

Adjustable Loading Dock Wheel Risers create a bridge for semi-trailers to use that can match your loading docks specifically to your operations. Preferred loading and unloading is when the trailer bed is 2” to 3” above the building floor, which can easily be achieved even with necessary drainage outside a building.

 

The Z-Deck trailer lift raises trailer tires with a sloped deck that minimizes the angle of the lifting surface to keep the trailers from rolling away under their own weight. Designed to work with wall mounted vehicle restraints, the Z-Deck trailer lift matches the stroke of the lift cylinders to the vertical travel of a wall mounted restraint to increase the overall safety of the dock system.
