The present invention relates to an integrated overloaded and braking safety device appropriately applied on the winding mechanism for loading; wherein, brake nut piece equipped with gear wheel of the general mechanical ratchet brake set is redesigned to be separate gear wheel, brake nut piece and gliding spring seat, and by making use of the action of spring force, the abovementioned three components will be combined to be part of the gliding clutch; moreover, via the foregoing improvement, the ratchet brake set and gliding clutch will be integrated as one provided with the function of overloaded-glide and brake. Hence, the effect of safety operation of load-hoisting for the winding mechanism will be acquired.
