A lifting device for steel material loading/unloading and construction comprises an annular base plate and a lifting arm obliquely arranged, wherein a lifting ring is arranged at the upper end of the lifting arm; an inner annular groove is formed in the top surface of the annular base plate, an inner guide plate is arranged at the lower end of the lifting arm, and the inner guide plate is arranged in the inner annular groove in a sliding manner. The lifting device is reasonable in structure, convenient to manufacture and simple to operate, can realize steel loading/unloading and transporting movement, save labor and greatly improve the construction efficiency, and is high in construction speed, safe and reliable. During the use, the lifting arm can slide in the inner annular groove through the inner guide plate, so that the position of the lifting arm on the annular base plate is changed, and the use is flexible and simple. A support arm is connected to the lifting arm, an outer guide plate is arranged at the lower end of the support arm, an outer annular groove positioned on the outer side of the inner annular groove is formed in the top surface of the annular base plate, the outer guide plate is arranged in the outer annular groove in a sliding manner, and the stability of the lifting arm can be effectively ensured by the support arm.
