The invention discloses a hoisting device of a 110kV and above-voltage-grade transformer coil. The hoisting device comprises an upper hoisting frame, wherein the upper hoisting frame is connected with a hoisting oil cylinder, the hoisting oil cylinder is controlled by a hydraulic station to start, and a hoisting jaw mechanism with an adjustable length is connected to the lower part of the hoisting oil cylinder. The hoisting oil cylinder controlled by the hydraulic station acts accurately and rapidly, and the hoisting device is simple to operate, so that the labor intensity of an operator is reduced; meanwhile, the length of the hoisting jaw mechanism can be adjusted, the position of the hoisting oil cylinder can be regulated according to the shape of the coil, and the hoisting device of the coil can satisfy demands of different models of products. The hoisting device is reasonable and compact in structure, convenient to use, and wide in application range.
