摘要： A hoist and traction machine having a mechanical brake, in which an operating handle is non-rotatably and axially movably interposed between a stopper provided at an axial end of a driving shaft and a driving member screwable with the driving shaft. Between the operating handle and the stopper is provided a regulation unit for regulating a relative rotation range of the driving member with respect to the driving shaft so as to enable release of the regulation by moving the handle away from the driving member, so that the driving member is moved away from a driven member by of moving the operating handle from the driving member to be normally rotated in a free-rotation operation mode whereby the braking action of the mechanical brake by a braking ratchet wheel and braking plates is released to control the free rotation of the driving shaft and the elastic biasing member biases it to maintain the state of free rotation control.

摘要： A hoist and traction machine having a free rotation control device/apparatus for selectively controlling the mechanical brake to be inoperative and for maintaining the inoperative mode of the mechanical brake, so as to control the free rotation of the load sheave. The free rotation control device is designed such that improved free rotation control operation can be provided, and the range of the pulling force for the chain can be enlarged in the controlled free rotation of the load sheave; thus, allowing the chain to be pulled quicker, while requiring little operating skill. Further, free rotation operation is not provided when the load sheave (and thus the driving shaft) is subjected to a large load acting in the direction of hoisting down the load, thus achieving highly improved safety.

摘要： One of the hand wheel and the brake ratchet wheel is provided with a cover portion extending toward the other thereof and having a circular peripheral surface which covers the lining plate, and the other of the hand wheel and the brake ratchet wheel is provided with a circular opposite peripheral surface opposed to the circular peripheral surface, so that opposite peripheral surfaces of those circular peripheral surfaces can be arranged adjacently to each other or have a scaling member interposed therebetween. Therefore, even when dust and rainwater enter a wheel cover for a hand wheel, these dust and rainwater can be prevented from further entering a mechanical brake.
