In most of the Lifter proof of concept examples the Carriage was tilted by human effort. The Lifter on Incline was an exception, relying on batteries. The video to the right shows the Carriage tilted using the weight of water, as it is pumped from one blue container to the other. A Lifter that used a moving weight method to tilt was first seen here Sliding Weight .
The video shows that the concept of an automated Lifter is feasible. A battery and charge controller may be used with the panels. This example shows that a battery isn't required, however without one your tilting Lifter may come to a halt when a cloud passes over.
Additional improvements are needed before the Carriage is loaded up. Each tilt ends quickly. A damping method needs to be developed. Also, a cutoff method has to be added.
The power needed to run the 12 volt water pumps comes from two 12 volt 30 watt solar panels connected in parallel. The panels have a digital volt/amp meter and a DC-DC step down converter between them and the pumps. The panels put out 18 volts and the pumps ran at 10-11 volts at 1.2 amps. The blue containers will hold 7 gallons.
The pumps are rated at 500 gph. That means that they could pump 8 gpm. A Carriage holding 500 lbs, plus the Carriage itself, needs between 48 to 56 pounds applied to the Extended Tilt Arm to produce a tilt. This can be varied by varying the location of the containers on the tilt arm. This Lifter takes around 13-14 tilts for 1 foot lift. At 8 gallons per minute, it should take about 15 minutes for a one foot movement up the Vertical Support or 4 feet per hour.
Solar Panels used to tilt Lifter Carriage
I used these panels, 30w Watts Newpowa 12v Poly Solar Panel Module Rv Marine Boat Off Grid
This is the pump used, Johnson Pumps 48503 500 GPH Aerator/Livewell Pump
Note: The meter I had connected showed 1.2 amps on the out put. The pumps are rated at 2.5 amps at 12 volts.
You might have noticed how quick the tilting cycle occurred at the start of the video. That changed as soon as I allowed the fulcrums to engage the Vertical Support. A full tilt passes through the tilt angle twice with the fulcrum opposite the secure one being raised past a level position on up to a height the tilt angle allows. In the beginning the Carriage was only going through a half tilt. This is also why it didn't exhibit as rough of a tilt back as it did later in the video. See the next video and watch the fulcrums.
