The actuators that many builders of small front end loaders use have an original intended use in medical and residential furniture. They move very slowly. I have been experimenting with increasing the voltage input from 12 volts DC to 20 and 24 volts. The purpose is to increase the speed of the actuator. The conclusions I have come to indicate that increasing to 20 volts will have little or no negative effects on the actuators. At the 24 volt level some actuators seem to hold up fine while others fail in the limit switches. Hence, the question : What can be done to compensate. That is what this video is about. There are links below to the necessary parts.
In this video I will disassemble and reassemble an actuator. I will also describe what I do to make the limit switches more effective for the increased voltage. I do not show the actual soldering of parts in place. If you have the necessary experience to work on these actuators, you do not need to see me solder. If you do not have the experience, then seek the help of a friend that does.
You will need basic tools, wire cutter/strippers, needle nose pliers, flat and phillips screw drivers, etc, etc. Solder, electric tape, and heat shrink tubing will also be needed.

Electrical info Changing 5amp Fuse to 10amp Doubles heat of wire. before it Blows .. Reason for some House Fires. Most electrical Motors can handle 30 % to 50% more draw with out Destroying motor . because of startup draw. Actuators short cycle Use. Heavy, Long or High RPM Loads = Heat or over Revs. Bad for Motor

Thanks for your thoughts. But before this video was made I performed some rigoruos testing in real life applications in order to see just how far the electical system could be challenged. I have checked with the Chinese manufacturers and have found that the actuators I use are manufactured to handle 24 volts. (In fact, I have one in my recliner chair that came from the factory that runs at 24 volts). I have had only one actuator fail and that was only after I applied 40 volts to it in an experiment and the failure was mechanical not electrical. Since this video was made I have found that with the right alterations I could operate these actuators at 48 volts in real life application without any overheating, blown fuses, burned wires or burned out motors. I have informed my subscribers of possible damage or shortened life caused by increasing voltage. In reality, aside from the one incident mentioned above, the only damage that has ever occured has been of a mechanical nature, not electrical - and I am talking about years of use.

Is there another way to prevent the 24v from pushing the actuator apart, rather than changing the micro switch. Like a limit stop on the travel of the loader arm?

I am currently running 24 volts on a loader without having changed the limit switches. The truth be told - in my voltage experiments with these actuators, at 40 volts they will deffinitely come apart without upgrading the switches. At 24 volts I have only had one actuator out of many come apart. The loader I have been showing in my other videos has untouched stock 12 volt actuators on the lift arms - they have been running at 24 volts for about 2 months now without any problems. You may want to go ahead and use them as they are and then if you have a problem, go ahead and do the upgrades. That is the approach I am taking because I want to find out just how much use at 24 volts they can take. You can always opt to use 20 volts, as I have never had any problems with 20 volts. I have other videos that discusss options. 20 volts is a little slower than 24. Hope this helps, Ed
