摘要： A mechanical brake for a hoist and traction machine, which is provided with brake releasing force control layers at braking surfaces of a driving member opposite to lining plates. Each of the brake releasing force control layers comprising a heat-treated plating layer made of nickel phosphate, nickel chromium or chromium, so that the surface condition of each braking surface of the driving member can be controlled and the surface hardness can be controlled, whereby an initial force for the brake releasing during the lowering of a load or the releasing traction of a load is adapted to be lower.

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： A lever type traction machine including a pair of chain holders for holding a chain entering, between side plates, towards the load sheave. Each of the chain holders is provided with a chain-swelling (slacking) restraint portion for preventing the drain from slacking at the rear of the chain holders. The machine is especially advantageous in that the chain will not become entangled or slackened, even if the traction machine is operated up-side down or on its side.
