The invention provides a reinforcement cage hoisting device and method. The reinforcement cage hoisting device comprises a hoisting platform for manufacturing reinforcement cages and a hoisting mechanism for rotatably hoisting the hoisting platform; and the first side of the hoisting platform is rotatably arranged to form a rotary side, and the second side of the hoisting platform is connected tothe hoisting mechanism and overturns along with the rotary side under the effect of the hoisting mechanism. According to the reinforcement cage hoisting device and method, the reinforcement cages aredirectly manufactured on the hoisting platform, and after the reinforcement cages are manufactured, the hoisting platform is supported on the lower portions of the longitudinal bodies of the reinforcement cages on the whole; the hoisting mechanism is adopted to overall overturn the hoisting platform to enable the reinforcement cages to upwards overturn from a horizontal state; in the whole process, the reinforcement cages are not affected by the external torque so that the reinforcement cages cannot be deformed and damaged; and thus the reinforcement cages can be converted into the vertical direction from the transverse direction in a stable state to ensure that the reinforcement cages are in a good condition, the groove entering efficiency of the reinforcement cages is improved, and construction of subsequent working procedures is ensured.
