The invention discloses a lifting installation technology for a steel structure arched door. The technology comprises the following steps that 1, five lifting points for lifting construction are selected from a structure of the steel structure arched door; 2, five truck-mounted cranes are selected, and ground hardening treatment is performed below the cranes; 3, crane drivers adjust actual loads and turning radius at four times according to instructions of a lifting commander in the lifting process; 4, the two truck-mounted cranes on the two sides of the arched door are auxiliary cranes and are matched with the three main cranes below the arched door for hooking during lifting, and the auxiliary cranes will rotate while the main cranes conduct lifting; 5, steel member column feet are conveyed onto a steel member foundation, the auxiliary cranes conduct unhooking and unloading, the three main cranes are in full load, and steel members are put in place; and 6, the steel members and the foundation are welded, and the three main cranes conduct unhooking and unloading after welding is completed. The lifting installation technology for the steel structure arched door is simple and easy to implement, risks caused by overhead operation are reduced, and the construction step of supporting an operation platform overhead is omitted, so that the construction cost is lowered.
