The invention discloses a six-lifting-chain chain hoist capable of adapting to high-precision quick ascending and descending. The six-lifting-chain chain hoist comprises a main machine body and a windlass mechanism; the windlass mechanism comprises a second upstream wheel axle, a first upstream wheel axle, a second upstream wheel, a first upstream wheel, a downstream wheel axle, a downstream wheelI, a downstream wheel II and a downstream wheel III, wherein the second upstream wheel axle and the first upstream wheel axle are parallelly arranged in a front-back staggered mode, and the downstream wheel I, the downstream wheel II and the downstream wheel III are arranged side by side; the two upstream wheel axles are arranged on bridging plates on the lower portion of a main wallboard, the downstream wheel axle is centrally fixed to a hook housing plate, the two upstream wheel axles are perpendicular to the shaft axis space of the downstream wheel axle, and the reference diameter of eachdownstream wheel chain ring groove is equal to the distance between central planes, for allowing lifting chains to be engaged, of the first upstream wheel and the second upstream wheel; the distance between axle hole centers of the first upstream wheel and the second upstream wheel is equal to the distance between central planes, for allowing lifting chains to be engaged, of the adjacent downstream wheels; after the lifting chains in transmission connection with the main machine body are wound around the downstream wheel I, the first upstream wheel, the downstream wheel II, the second upstreamwheel and the downstream wheel III, the heads of the lifting chains are hung on the bridging plates, the formed six lifting chains are vertically stressed and do not skew, and the engagement precision is higher than that of quick ascending and descending.
