The invention provides a hoisting pulley assembly displacement mechanism. The hoisting pulley assembly displacement mechanism comprises a vehicle frame, and also comprises two sets of pulley assembly displacement devices symmetrically arranged along the center line of the vehicle frame, and each set of the pulley assembly displacement devices comprises: a track arranged on the vehicle frame; a seaside driving pulley trolley arranged on the track; a seaside hoisting pulley assembly fixed on the seaside driving pulley trolley; a landside driven pulley trolley arranged on the track; a landside hoisting pulley assembly fixed on the landside driven pulley trolley; a speed reduction motor arranged at one side of the seaside driving pulley trolley; and a speed reduction box, wherein the input shaft of the speed reduction box is coupled to the output shaft of the speed reduction motor. A quay crane having two single-suspender and double-suspender work modes and adopting the hoisting pulley assembly displacement mechanism can effectively alleviate the influences of inertia force and wind power on suspenders when the vehicle starts and brakes under a single hoisting system in order to improve the working efficiency of a driver.
