| Posted: 16 Nov 2010 07:40 PM PST May I know that how to convert the rack and pinion (with ratchet) horizontal motion to vertical lifting a human weight by adding some mechanism,structure or linkage? And is it possible to lift a human weight by just the force supply by hand with those mechanism stated above? without using motor or hydraulic... Or any other mechanism idea can use to lift up a human like scissor jack,or...? Thanks for anyone giving me ideas. |
