The invention discloses a lifting hook limiting device applied to hoisting machinery. The lifting hook limiting device comprises a shell, a motor, a limiting rod and a rope guide, wherein one end of the shell is fixedly connected with the motor; a limiter is arranged at the interior of the motor; one end of the limiter is fixedly connected with one end of the limiting rod; the other end of the limiting rod stretches into the other end close to the shell in the shell; a baffle a and a baffle b are arranged at two ends of the limiting rod respectively; the rope guide is arranged between the baffle a and the baffle b; a winding drum is arranged at the bottom of the shell; two ends of the winding drum are fixedly connected with two ends of the shell through a coupler a and a coupler b respectively; a limiting switch is arranged above the winding drum. The lifting hook limiting device has the beneficial effects that the structure is simple, the objects are lifted by a pulley block structure; the time is saved; the labor is saved; the condition that the device stops working due to failure of a potentiometer can also be avoided; the couplers are connected with the winding drum, the vibration can be effectively reduced; meanwhile, nuts and bolts are used for fixing the baffles on the limiting rods; the phenomenon that the baffles move by virtue of reciprocating movement of the rope guide is avoided; the unnecessary economic loss is avoided; the lifting hook limiting device is relatively stable in operation process and high in safety.
