ABSTRACT:
A compact lifter assembly having a base plate and a first intermediate plate rigidly connected by a first pair of shafts. A second intermediate plate is slidably attached on the first pair of shafts to be disposed between the base plate and the first intermediate plate. A second pair of shafts extend from the second intermediate plate, through apertures in the first intermediate plate for rigid connection to a mounting plate. A linear actuator centrally located on the base plate is actuated for lifting the mounting plate and a second intermediate plate relative to the base plate. The shafts are rigidly connected to the respective plates by a retaining ring and split taper plugged shaft retention to provide a zero clearance shaft joint connection.
