Basic Lifting Mechanisms
The most unique feature of a rolling ball sculpture is that once the balls get to the top of the sculpture, gravity takes over to keep everything in motion. Getting the balls to the top of the sculpture is the job of the lifting Mechanism. I have incorporated many different and unique lifting mechanisms in my sculptures, each selected based on many different factors. The basic lifting mechanisms represent the simplest and most common ball-lifting methods.
If you enjoy these contraptions, and know others who would, please share:
The Chain Lift
Standard roller chain components and simple design make the chain lift one of the most economical and robust lifting methods.
The Curved Chain Lift
This is a chain lift with a curved lifting track. The curve helps the lift conform to a sculpture's shape.
The Screw Lift
Also known as an Archimedes' screw, this lift is an inclined plane wrapped around a column. Balls are pushed slowly up a vertical track.
The Belt Lift
The ball is constrained between a moving belt and a vertical track. Friction keeps the ball moving upwards.
