Provided is a hoisting method for mounting and dismounting an elevator head sheave. By means of the hoisting method, dismounting and mounting of the head sheave in a hoisting mode are achieved through existing site conditions, a few (four) small hoisting machines and a few (six) operators. The method comprises the steps of mounting and hanging side-opened type pulleys and manual chain type cranes; untying a large rope from a cage, sleeving a sliding sleeve connector with the large rope, retracting the large rope and dragging the large rope back through heavy chains; sleeving the head sheave with the large rope and the heavy chains, and hoisting the head sheave through the large rope and the heavy chains synchronously; dismounting a shaft structure of the head sheave, and hoisting and forwards moving the head sheave through cooperation of the large rope and the heavy chains; and tying a left balance rope and a right balance rope, and hoisting the head sheave through cooperation of the large rope, the left balance rope and the right balance rope.
