The invention relates to the technical field of high-altitude operation, and provides a lifting device and lifting equipment. The lifting device comprises a lifting assembly, a mounting rack and an overload recognition assembly, the overload recognition assembly comprises a limiting part, a pre-tightening part, an overload spring and a displacement monitoring part, the limiting part is connected with the mounting rack, and the first end of the pre-tightening part slidably penetrates through the limiting part and then is connected to the lifting assembly; the overload spring is arranged on the pre-tightening part in a sleeving mode, one end of the overload spring abuts against the limiting part, the other end of the overload spring abuts against the second end of the pre-tightening part, and the displacement monitoring part is arranged on the mounting rack and used for monitoring displacement of the overload spring and/or the pre-tightening part relative to the displacement monitoring part. According to the lifting device provided by the invention, the overload information can be directly reflected through the overload identification assembly, and the overload spring and other components are low-cost components which are easy to obtain, so that the burden of the lifting device in the aspects of production, manufacturing and use can be effectively reduced.
