Scissor lift with vertical cylinders
Hi to everybody!
I need to design small-sized lifting mechanism, for my course project. Then I fount this US patent [url]http://www.google.com/patents/US4113065?printsec=abstract&hl=ru#v=onepage&q&f=false[/url]
In that patent was mentioned about the "traditional" scissor lift. However, if we ask google "scissor lift" we can see, that in generally, "traditional" construction with one cylinder, which rise from almost horizontal position, is being used. So I hesitate in my decision... who have already concerned with question? who have any idea, why construction of scissor lifts with vertical cylinders are not so widespread?
p.s. For my project I need lifting mechanisms to elevate 500 kg (1400 lb) in 6 meter (16,7 ft) height.
