摘要: An apparatus for moving a car along a travel path along guide rails includes a linear drive having a fixed first platform attached to the car and connected by springs with a movable second platform. Holding-units are attached to both platforms for engaging the guide rails and operating-units are connected between the platforms for relative movement. The holding-units and the operating-units include piezoelectric actuators that are selectively energized to move the car.
