ABSTRACT:
The lifting beam assembly for transporting workpieces from work station to work station in a forming press includes a pair of transport beam members for grasping workpieces to be transported within the forming press. A first drive mechanism executes vertical movement to raise and lower the transport beam members. A second drive mechanism executes longitudinal movement of the transport beam members in a direction parallel to the direction traveled from work station to work station. A third drive mechanism executes transverse movement of the transport beam members. Each of the three drive mechanisms include movement actuating devices for effecting the respective vertical, longitudinal and transverse movements. An actuating shaft is secured at one end thereof for hydraulic actuation by an electro-hydraulic booster. It is coupled at the other end thereof to the movement actuating device for effecting the particular respective movement of the transport beam members. Various features of the individual portions of the structure are also set forth.
