This text roundly introduce lift's sort, after ascertain want designed scheme, namely aim at lift's structure and require proceed design and explanation, at the same time, at the lift design process,it is need to proceed additional remarks be involved in usebility problem. And then analyses bibcock type autumobile lift's main upright, section charateristic, and check strong rigidity with bracket. Both that of design with hydraulic cylinder piston perch intensity also proceed proven pressed bar, as well as select and count with chain and wire rope tobe sure satisfy the lift operating requirement. This test is stream-actuated bibcock type automobile lift.
