It is committed to solving the pain points and demands of tower crane drivers at work:the driver needs to stay in the tower crane cab with a narrow space for a long time; the cab makes it difficult for drivers to go to the toilet; the cab is designed with an unreasonable layout, which is inconvenient for operation, etc,. Based on user demands and intelligent development trend, this paper aims to provide effective guidance for the design of tower crane cab. Through literature study, interview method is used to research user requirements and translate them into the design point and smart technology combining site, and set up the level of the tower crane intelligent cab design demand analysis model. The analytic hierarchy process (AHP) is used to calculate the weights of every demand indexes, and complete the consistency check, then end up with a design scheme of high quality. This paper summarizes the pain points and demands of tower crane drivers and transforms them into design points and intelligent technology combination points. Based on this, a hierarchical analysis model of design requirements for tower crane intelligent cab is proposed, in which the important order of the first level indexes is safety, comfort, intelligence and convenience. Finally, based on user demands and the future development trend of tower crane, a tower crane intelligent cab scheme is designed and applied from intelligent monitoring system, intelligent interaction system, intelligent health system, intelligent glass interface and other aspects.
