Making Tipper Trailer with independent Power Hydraulics 12v

I used a 12v hydraulic power supply that comes from a tail lift from a small van, The power supply has a built-in section divider, which makes it easy to install. To control the power supply I used a relay and a 12v winch pilot and receiver, and a 12v 20ah gel battery. The hydraulic trailer can be attached to any vehicle, mower tractor, quad and car. Dump trailer the maximum weight it lifts is about 400 kg, limited by the strength of the wheels, if not for the wheels, it would be possible to easily transport and unload larger loads
