| 20110264270 | Truck Restraint for Loading Dock - A device for restraining a horizontal bar at the rear of a vehicle to a stationary support adjacent a loading dock, the device having: a frame having a vertical track and a mounting bracket for securing the frame to the stationary support; a suspended carriage mounted to the track for vertical movement relative to the track, the suspended carriage having a forwardly and upwardly extending member; a vertical motion actuator mounted to the frame and having: a master carriage slidably mounted to the suspended carriage, the master carriage engaging the suspended carriage for moving the suspended carriage between a lower retracted position and an upper engaged position wherein the member engages a forward surface of the horizontal bar; and a resilient suspension member disposed between the master carriage and the suspended carriage and having a resilient range of travel, whereby the suspended carriage is capable of vertically floating relative to the master carriage within the range of travel; a control system including: a suspended carriage position sensor on at least one of: the master carriage; and the suspended carriage for determining the position of the suspended carriage relative to the master carriage; and a processor in communication with the position sensor and the vertical motion actuator that: determines when the suspended carriage has engaged the horizontal bar by measuring the relative distance between the suspended carriage and the master carriage; and produces a signal command to the vertical motion actuator to move the master carriage relative to the suspended carriage by a predetermined distance. | 10-27-2011 |
| 20110258788 | DOCK LEVELER FOR LOADING DOCK WITH INTEGRAL ON-DEMAND COMPRESSOR AND PNEUMATIC ACTUATOR - A loading dock leveler having: a base having an inward end; a deck with a top platform, the deck having an inward end hingedly mounted to the inward end of the base for movement between an upper position and a lower position; an on-demand air compressor with an electrically powered motor, the compressor having inlet in communication with a source of ambient air and a compressed air outlet; a pneumatic deck lift actuator pivotally connected to the base and to the deck for rotary movement between a raised position and a lowered position, the lift actuator having a lift chamber, and an inlet port in direct communication with the compressor outlet through an electric powered lift valve to the lift chamber, and having a vent valve in communication with the lift chamber; and an electric user control interface having: an electric up/down switch in communication with the motor to conduct electric power to the motor and open the lift valve in an up position, and to prevent conduction of electric power to the motor and open the vent valve in a down position; wherein the compressor, motor, lift valve; vent valve and lift actuator are disposed between the base and the deck. | 10-27-2011 |
| 20100266375 | VEHICLE RESTRAINT SYSTEM - The invention relates to a vehicle restraint system for preventing forward movement of a vehicle away from a loading dock, having a base, an arm rotatably mounted to said base for rotating between a lowered position out of contact with said vehicle, a partially elevated position comprising a predetermined range and an upright position wherein said arm may contact said vehicle to restrain said vehicle in a position suitable for loading or unloading, an arm rotator for rotating said arm between said lowered and upright positions, a contact sensor for detecting contact between said arm and said vehicle, a position sensor to detect the rotational position of said arm, a lock, and a lock actuator in operative communication with said contact sensor and position sensor for actuating said lock to retain said arm when in said upright position. | 10-21-2010 |
