The platform stands vertical and pivots 90 degrees to lay flat. Due to the weight of these gas cylinders, I need some sort of spring assist, much like a roll up door would use. The platform is 26"" W x 48"" L and has a pivot point about 12"" from one end. I would like to mount a counterbalance spring underneath, using two cables traveling about 18-24"" to assist in manually raising & lowering this Contact Info (联系信息) Russ Rugg CA 95351 USA Company: Rayco Industrial Supply Title: Service Manager E-mail: rayco-tools@sbcglobal.net rayco-tools@sbcglobal.net mingluji.com2011-2012Contact Us(联系我们) Mobile | Computer
