Inquiry (采购产品): David Round Hoist Parts Hello I have a David Round Air Hoist. The size info is rubbed off the decal, it looks like a 1 ton or so. We use it to lift up an object that weighs about 250 pounds in a truck wash. I took this hoist a few months ago that was partially foze up and tried to rebuild it. One of the small pieces of spring metal that keeps the blades on the air motor when it is spinning had gotten stuck in the case causing it to jam. I need to see if I can purchase a rebuild kit for the air motor. The motor has a 3/4" shaft with 1/2" inlet & exhaust ports. If you canhelp me to identify this hoist I would appreciate it.
