I have gotten loads of very high quality maple plywood out of a dumpster at a Laser shop and I needed a way to pull it out and be close to the dumpster to hook it . We used to pull it out through the overhead door at the end of the dumpster with their long hook made out of threaded rod but it was real hard to control. So I decided to make this frame to hook over the side of the dumpster so I could pick from anywhere. The step platform is made from some the material re cycled from there too. I also made a 6' long hook out of 1/2" rebar and you can see it laying over the rail and the dumpster in the first shot.
The frame is made from 1/2" rebar bent with a torch and stick welded together. The long hook is the same rebar.
It is very sturdy and we can make quick work of picking by using it, The last shot shows the form that the plywood is in when we pull it. some times there are some very large pieces. It comes in 1/2", 5/8" and 3/4" and it is very useful in the shop and it is FREE.
