Rack and Pinion
Here is another example of a Lifter using a rack and pinion method to position and hold the carriage of a Lifter as it is tilted up its vertical support. A previous version was first shown earlier here Sliding Pinion.
I modified the placement of the pinions in this new design by placing them at the end of fulcrum support arms. The fulcrum support arms are located at the fulcrum positions along the base of the carriage and are free to move as the carriage is tilted. Each tilt pushes the pinions resting on the rack projections up along the vertical support.
In the video you can see that this lifter, like most, is designed for two people to operate. The tilt arm is easily made longer if needed to add additional mechanical advantage for reducing the effort needed to tilt.
This image below shows the light produced by the two satellite lamps seen in the video.

This image shows the light output from the work lamp seen in the video. It is attached to the garage door.
For a given generator and light source, the brightness is dependent on the rpm of the generator and the generator rpm is dependent on how much weight there is in the carriage and the gear ratio delivering torque to it. LED lights also has a clamping voltage and serves as a speed regulator to the generator and the Lifter drop speed.
