Unit To Open And Close Sliding Doors On Large Machinery Barns

Unit to Open and Close Sliding Doors on Large Machinery Barns BUILDINGS Miscellaneous 14-4-26 We've built two of these to open and close sliding doors on large machinery buildings. Each unit consists of a large truck rim, 1/3-hp. electric motor, gear reducer, 60 ft. of 3/ 16-in. cable, a microswitch to stop the door, a reversing switch, a pushbutton control switch, and wiring. The motor, truck rim and gear reducer mount on an angle iron frame off to one side of the door. Works very well. (Paul Pence, 2261 Walcutt Rd., Columbus, Ohio 43228 ph 614 876-7835)
