Making Electric & Hydraulic Dumper Truck

- Hydraulic pump build Hydraulic Control Valve - Conversion So far, it is the largest and most complex project we have ever done. As you can see in the video, it is not 100% finished yet, but it is already working and driving. In the next video we will try to show you the completely finished and painted project and show you a longer test and all the functions of this vehicle. As a drive, I used worm gear motors that come from a broken wheelchair. Each of them has 150 watts, and thanks to the additional chain transmission, the wheels have a very high strength. The drive wheel has 10 teeth and the take-up wheel has 43 teeth. The chassis frame is made of high-strength materials, most of the wall thickness is 3 and 4 mm. 12V 100ah gel batteries are connected in series to give 24V In order for the switches for driving and control to last a long time, I decided to use relays.
