All Lifters have a Carriage or an object configured to function as a Carriage. With this in mind a Carriage has the following characteristics:
1. Built sturdy enough to hold the weight it carries when tilted.
2. Placement location for two Fulcrum supports at the bottom or top of the Carriage.
3. Ability to move freely vertically up one or more Vertical Supports or an incline.
4. Ability to move freely in a left or right direction when tilted and if needed horizontally.
5. One or more points to receive a tilting force.
In addition to the basic Carriage design it may also have built into the Carriage or attached to it:
1. Extended Tilt Arms along its side to increase the tilting force when applied.
2. A Fulcrum Assembly, which may be a plunger, flapper, ratchet gear or sliding pinion, etc.
3. A Tilt Assist Assembly to support pulleys or other tilt assemblies for increasing an applied tilt force.
A Carriage requires the following for it to be useful as a Lifter:
1. A Vertical or Incline Support structure.
2. A method to apply a tilting force to the Carriage.
3. A mechanical assembly for the extraction of its Potential Energy.
Since there are so many ways to build a Lifter that can meet the above requirements, the following designs are meant as suggestions only. They are intended to provide starting points for future designs. As can be seen in the Proof of Concept Section, most of the proposed Lifter designs are easily built and implemented.
