The invention relates to special mechanical equipment, in particular to a vertical transportation machine, which is applied to building construction and maintenance, or applied to warehouse, wharfs, dock, high towers and the like for a long time. The vertical transportation machine comprises a base, a bottom cage enclosure, a suspension cage assembly, a transmission mechanism, a standard joint, a guide rail and a wall-attached frame, wherein the bottom cage enclosure is fixed on the ground, the base, the suspension cage assembly and the transmission mechanism are sequentially connected by the standard joint and the guide rail from top to bottom, and the standard joint and the guide rail are heightened along with a building which is constantly risen within allowed installation height ranges. The construction hoist is characterized by further comprising a double lifting lug component, the suspension cage assembly and the transmission mechanism adopt a double lifting lug form, and a couple of main components are improved, thereby the vertical transportation machine has the advantages of strong stability, good perpendicularity, simple structure, high safety performance and the like.
