Powered Lifter

All Lifters require some energy source to function. They can be designed to receive that source of power from tidal, wind, solar, human or animal power sources.

Since a Lifter is highly configurable, it can be designed to use electric motors to provide the tilting and carriage action. This enables the Lifter to be positioned within any reasonable distance from its source of power. By combining the power sources mentioned, a Lifter could be actively raising the Carriage over a longer period of time. In the case of a Lifter combined with a Gravity Bank and Carousel, the Lifter would be able to recharge the Gravity Bank and keep the Carousel active.

The figure to the right shows a Screw Lifter. Three motors are used to provide the Lifter action requirements. There are two Motor Fulcrum Position Assemblies used to move the Fulcrum Support Arm along a Vertical Support. Another motor is located in the Motor Tilt Assembly providing the power needed to tilt the Carriage through a tilting cycle. Electronic control assemblies would activate each motor assembly as needed, keeping the Carriage moving up or down the Vertical Supports.

A Tilt Rack is shown where the Pulley Assembly usually goes. The electric Motor Tilt Assembly gives a varied choice of tilting options. Pulleys, gears, worm gears, etc. could easily be used to provide the tilting power required.

Screw Lifter with Motor Assist


An added benefit of the Motor Assist Lifter would be the ability to build Lifter Farms receiving their power from multiple sources and locations.
