Is this a new, or new to you dump truck ? Over the years many people have been killed by dump box"s coming down too fast, it can happen when a hose breaks, or is tampered with.it can happen when someone is checking, or maintaining the system, and didn"t block the box up properly. A CORRECTLY installed hydraulic system will have a check valve installed. The check ball will be pushed open by fluid lifting the dump box. Then it seats. The check ball has a hole drilled in it. when you lower the box, the check ball remains closed, and fluid can only get out through the small hole in the ball, thus the box lowers slowly. It may be frustrating, but it"s there to save your life. I can"t remember the specific name of that check valve, but different sizes are available. A hydraulic schematic should show one in your circuit. Replacing it with a larger one, would be like putting a 50 amp fuse in a 10 amp circuit! Don"t do it! Live with it!
