Automobile lift is an equipment that is intended to bearing one region of automobile chassis or unit construction ,and leading automobile rise and fall .It entire car overhaul just the same turnaround service,both can not get away it to automobile life at automobile service curing suffer exert vital action ,soever .As lift familial one key menber ,bibcock type automobile lift has any other lift cannot analogical advantage :Such as,it adopt large bibcock struture ,scope of work expand, can repair high scaffold vehicle, operating space open, and so on. This text roundly introduce lifts sort, after ascertain want designed scheme, namely aim at lifts 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 lifts main upright, section charateristic, and check strong rigidity with bracket. Both that of design with hydraulic cylinder piston perch intensity also proceed proven with compressed bar, as well as select and count with chain and wire rope to be sure satisfy the lift operating requirement. This test is stream-actuated bibcock type automobile lift.
