The invention relates to the field of hoisting, in particular to a curved surface roof covering layer hoisting device. The device comprises a machine body and a supporting column, wherein the supporting column is rotationally arranged in the top wall of the machine body, a hoisting cavity is formed in the supporting column, a hoisting device which drives a swinging arm arranged above the supporting column to move up and down is arranged in the hoisting cavity, and the hoisting device moves upwards to drive a suspension frame arranged below the swinging arm to move. According to the curved surface roof covering layer hoisting device, hoisting of a curved surface roof covering layer can be realized; when the device is used for hoisting the curved surface roof covering layer, the device can be firmly fixed, meanwhile, the device can hoist the covering layer to a relatively high position so that the device can conveniently move; and meanwhile, a hoisting object can be moved to the position right above the machine body when the device moves, then the gravity center of the device is ensured to be located above the device, the device is prevented from toppling due to instable movement, and the device is more safer, good in stability and convenient to produce and popularize.
