A pair of horizontally spaced and horizontally extending part support rails or elongated platens are each guided and supported for vertical movement by a pair of guide and support members having linear bearing blocks mounted on vertical guide rails attached to corresponding vertical housings. A bell crank is pivotally supported adjacent each housing and is pivotally connected to the corresponding bearing block by a first link member. Second and third link members pivotally connect each pair of bell cranks for each platen to each other and to a crank arm mounted on a horizontal crankshaft extending laterally below the platens. A combined electric motor and gear reducer have an output shaft coupled to one end portion of the crankshaft, and an electric brake unit is connected to the motor shaft. An overtravel arm is also secured to the output shaft of the gear reducer and actuates an overtravel switch connected to control the electric motor. The output shaft also drives a programmable limit switch and feedback device for precisely controlling the electric motor and brake unit according to the position of the platens.
