The invention discloses an intelligent arm rising and falling control device and method for the tower condition of a crawler crane. The intelligent arm rising and falling control device comprises a controller, a primary arm angle sensor, a secondary arm angle sensor, a primary arm tension sensor, a secondary arm tension sensor, a display, an operating handle, a safety protection part and a one-keyarm rising/arm falling allowable switch as well as a primary variable-amplitude winch proportional valve, a secondary variable-amplitude winch proportional valve and a superlift variable-amplitude winch proportional valve. The controller is used for obtaining primary arm pull plate force information detected by the primary arm tension sensor, simultaneously obtaining secondary arm pull plate force information detected by the secondary arm tension sensor, getting the pull plate force information and sending the pull plate force information to the display to be displayed. According to the intelligent arm rising and falling control device and method for the tower condition of the crawler crane, the efficient automation degree of the arm rising/arm falling process is guaranteed, and the construction efficiency and construction quality are significantly improved.
