ABSTRACT:
The truck locking device includes a flat substantially triangular shaped support member having a vertically extending surface and an inclined surface, a pair of locking arms pivoted adjacent the intersection of the vertical and inclined surface on opposite sides of the support member, a pair of double acting pneumatic cylinders mounted on opposite sides of said support member for moving the locking arms into and out of engagement with a standard ICC bar on the back of a truck and an activating arm pivoted on the support member for pivotal movement under the influence of the bar as it is moved over the locking device to operate a valve to cause the pneumatic cylinders to move the arms upwardly for engagement with the bar to lock the truck in position relative to a loading dock or the like. A second valve is provided for activating the cylinders for retracting the locking arms upon completion of a loading or unloading operation to release the truck. Upon departure of the truck the activating arm is spring biased to its original position for a subsequent truck locking operation.
