  • Publication number: 20150225991
    Abstract: A pneumatic door system and a method of using the same are disclosed herein. According to one embodiment, a trailer may include a seamless main door and at least one side door. The doors may be configured to be locked shut with a system of pneumatic locks. The main door may be configured to open and close as controlled by pneumatic pressure applied to a door cylinder. The pneumatic system may be configured to be controlled by an interior control box. The pneumatic system may be configured to operate off of pneumatic pressure in an auxiliary air tank, the pressure being protected by a series of one-way check valves. The pneumatic system may also be configured to operate wirelessly using RFID or Bluetooth technology, among other things, to secure the cargo and facilitate ingress and egress to the trailer.

  • Patent number: 9045924
    Abstract: A system for allowing a loading dock door to release from a track upon being struck by a fork lift or other sufficiently strong force. The system employs a unique track profile with one or more sidewalls that have an angled sidewall profile to allow a release assembly to move out of the track. The release assembly includes a biasing mechanism that allows the assembly to flex and ride out of the track when the door is impacted.

  • Publication number: 20150075077
    Abstract: A system for allowing a loading dock door to release from a track upon being struck by a fork lift or other sufficiently strong force. The system employs a unique track profile with one or more sidewalls that have an angled sidewall profile to allow a release assembly to move up the sidewall and out of the tracks, and a tensioned or spring loaded release assembly that allows the assembly to flex enough to ride up the sidewall and out of the tracks when the door is impacted.

  • Patent number: 8887442
    Abstract: A system for allowing a loading dock door to release from guide tracks. The dock door includes wheel-and-axle assemblies which are mounted to the door and which include wheels biased towards a position in the tracks. At least one of the tracks has a cross sectional profile which enables the wheels disposed in the one of the tracks to move out of the one of the tracks when the door is struck with sufficient force.
