Hoist with built-in load sensitive automatic speed change device
Abstract:
A hoist with built-in load sensitive automatic speed change device includes: a high-torque input member coupled to a hand wheel, a magnetic clutch coupled via a speed-increasing mechanism and configured to transmit a low load, and an output transmitting means configured to transmit a rotational operating force of the hand wheel to mechanical brakes via the high-torque input member or magnetic clutch, wherein the hand wheel is axially supported by a drive member coupled to the output transmitting means of the mechanical brakes and rotated thereby, the magnetic clutch is arranged between the speed-increasing mechanism and the hand wheel, the hand wheel and the speed-increasing mechanism are coupled by a hollow input member provided so as to cover the outer periphery of the magnetic clutch, the output transmitting means is fitted onto a boss portion of the drive member so as to allow torque transmission to the boss portion.
