The invention belongs to the technical field of rail traffic and particularly relates to assembly type mechanical rapid construction erecting equipment for a suspension sky train. The assembly type mechanical rapid construction erecting equipment comprises a crane erecting rail mechanism, a power control mechanism and a transporting and mounting mechanism; the crane erecting rail mechanism is usedfor hoisting and transferring a to-be-erected rail beam and a to-be-arranged vertical column; the power control mechanism provides power for the crane erecting rail mechanism and the transporting andmounting mechanism; the transporting and mounting mechanism can transport and mount the to-be-erected rail beam and the to-be-arranged vertical column; and the crane erecting rail mechanism is connected with the transporting and mounting mechanism and provides the to-be-erected rail beam and the to-be-arranged vertical column for the transporting and mounting mechanism. According to the assemblytype rapid construction erecting equipment for the suspension sky train, a foundation, a foundation platform and the vertical column can be assembled and constructed on site, the rail beam can be erected on site, and all structures (expect a station structure) are constructed in rapid, environment-friendly, assembled, mechanized and standardized modes.
