  • Patent number: 6309165
    Abstract: A repositionable brace helps support the legs of a swap body freight container parked at a truck loading dock. The brace can move from a retracted position to an engaged position. In the engaged position, one end of the brace is at least partially fixed relative to the dock with an opposite end engaging at least one of the container's four legs. In the retracted position, the brace is positioned to where it is more out of the way when not in use, or positioned to align the brace to legs at other various locations. In some cases, the brace pivots between the locked and retracted positions manually, hydraulically, electro-mechanically or pneumatically. Also, a firm landing pad can be associated with the brace to provide a more consistent, level height at which the swap body is parked.

  • Patent number: 6190108
    Abstract: A vehicle restraint employs a 4 bar linkage to lift a restraining member to a position that engages a vehicle thus restraining it at a loading dock. The linkage is upwardly biased to hold the unit in an engaging position and may be retracted by using any of a number of mechanical techniques such as hydraulic electric or pneumatic power. The 4 bar linkage transfers all loading on the unit from the ICC to the frame thus isolating any driven members from overloads. A secondary hook mounted to the 4 bar linkage is pivotally spring loaded to limit vehicle travel away from the dock and to extend the capture range of the device in the case of ICC's bars that are damaged or mounted at non-standard positions at the rear of the vehicle.

  • Patent number: 6106212
    Abstract: A vehicle restraint for a truck loading dock includes an actuator that rides up with a carriage to sense that a truck's ICC bar is within a predetermined region before fully extending a restraining member to engage the bar. The carriage and restraining member are raised and lowered by a drive unit, such as a cable extending from a winch. The winch may be attached directly to the carriage, or optionally remotely mounted to the dock. One end of the cable connects to a spring that compensates for incidental vertical movement of the ICC bar caused by the truck being loaded or unloaded. Large downward movement of the ICC bar is accommodated by a clutch associated with the winch. For large upward movement, the winch automatically restarts to pull the carriage up to meet the new height of the bar. An optional ICC bar deflector mounted at the base of the dock, along side the carriage, wedges underneath an exceptionally low ICC bar as the truck backs into the dock.

  • Patent number: 6082952
    Abstract: An automatic vehicle chock has a chock and a locking mechanism movable on a rail from a retracted position to a position where the chock is extended and held in position by the locking mechanism. A sensor moves with the chock to determine the position of the wheel to be chocked and extend the chock. The position of the sensor relative to the chock can be adjusted. The device also employs mechanical assemblies carried by the carriage assembly to retract the chock without the use of a brake. In one embodiment a cam is used to reverse the direction of the chock arm retaining spring after the chock has been engaged. In a second embodiment the chock is continuously biased to the stored position and a latch is used to hold the chock outward until it is locaked in posiion. The latch is then released and the bias to the stored position is restored so that the chock will retract when the lock is released.
