The invention relates to a tyre crane cab hoisting method. The innovation point is as follows: the method comprises the steps of manufacturing a rectangular frame type base firstly; dividing the rectangular frame type base into a left counter weight area and a right cab bearing area, placing a counter weight on the counter weight area of the base, arranging two fixed-length steel wire ropes and two chain blocks on the base, and connecting the two fixed-length steel wire ropes and the two chain blocks on the base with a lifting hook of a lifting appliance; hoisting a cab to the outside of a cab mounting position of a tyre crane by the lifting appliance and transferring the cab to the mounting position to be mounted; readjusting to increase the integral length of the chain block while the cab is mounted, and enabling a hoisting point and the gravity center of the base behind the cab to be consistent; and enabling the base and the counter weight on the base to be descended to the ground. The tyre crane cab hoisting method has the beneficial effects that the interference phenomenon of the cab and a trolley frame can be avoided due to use of a tooling, the mounting operation can be carried out smoothly and the safety factor is high.
