    Just wondering. I have never seen one in person, Are there safety features to them? That's a lot of weight to come flopping down .

    What variety of safety?

    When you dump, you unlock the gate and raise the gate with the cylinders. To lower, there is an orifice to restrict flow to keep the gate from slamming down as hard. A counterbalance valve could be plumbed in on some I suppose.

    What I mean is if something gives out and your standing under the gate working out of the back of the truck then that would be a bummer. What do they do to be sure you don't get killed by these set ups. I want one on the tri axle that I am buying but am trying to understand how or if they are safe

    A load check on the base of each cylinder would provide that, or lower the gate lift and let it hang open like a traditional gate.

    Ok, So I would in fact have to make a prop or something if I had one of these. No way am I standing under that thing. To Lower traditionally you need to pull the pins and then need a machine to get it back up. Plus I think it's uncomfortable driving with the gate down.

    A load check is a valve that prevents the cylinder from collapsing if a hose were to blow.

    I don't follow the rest, the high lift gates I've been around can swing like a typical gate or can be lifted for clearance. If you dump your load then lower the gate, before you lower the bed, the gate hangs towards the ground giving room to clean the apron and bed.

    Barn doors are better from a landscapers prospective..

    Those are good for dealing with large stone... NOT safe to work under!

    Right that's what I'm getting at. I might want to put a skid bucket in the back and lift the gate with the body down to hook it up. Or even work under it shoveling out of the truck. There were a million things I wanted to do that with when I had my international. I would probably make a good brace or go with barn door. It's a pain having all the fabrication done for barn door.

    we have all single axle dumps, but they are all a fairly crude barn door setup.

    I've found this to be simple and work well for landscape and general work. I'll see if I can get some pictures of one.

    Whats the pain, any good heavy duty truck shop or welder should be able to make your gate so it will swing out by putting in pins and removing the top pins and releasing the gate.

    Bobcat Ninja has one http://youtu.be/OWky6hhgxmw
