    摘要： A hoisting machine is provided that is capable of efficiently dissipating heat generated from an inverter incorporated in the hoisting machine main body into the surrounding air with a simple structure and hence capable of performing high-frequency operation. A hoisting machine having a load hoisting motor and a speed reduction mechanism and driving the load hoisting motor with an inverter 12 incorporated in the hoisting machine main body is provided with a heat dissipation means that dissipates heat generated from the inverter 12 to a speed reduction mechanism casing 15 that houses the speed reduction mechanism. The heat dissipation means is a means for attaching the inverter 12 directly to the speed reduction mechanism casing 15 in close contact therewith through surface contact at at least a part of the inverter 12.

    摘要： There is a hoist with built-in load sensitive automatic speed change device including: a high-torque input member 12 coupled to a hand wheel 18, a magnetic clutch 14 coupled via a speed-increasing mechanism 15 and configured to transmit a low load, and
    an output transmitting means 13 configured to transmit a rotational operating force of the hand wheel 18 to mechanical brakes 7, 8 via the high-torque input member 12 or the magnetic clutch 14,
    wherein the hand wheel 18 is axially supported by a drive member 10 coupled to the output transmitting means 13 of the mechanical brakes 7, 8 and rotated thereby,
    the magnetic clutch 14 is arranged between the speed-increasing mechanism 15 and the hand wheel 18,
    the hand wheel 18 and the speed-increasing mechanism 15 are coupled by a hollow input member 11 provided so as to cover the outer periphery of the magnetic clutch 14 so as to allow transmission of torque,
    the output transmitting means 13 is fitted onto a boss portion 10a of the drive member 10 so as to allow torque transmission to the boss portion, so that reduction in size of the load sensitive automatic speed change device and prevention of entry of dust or the like into the magnetic clutch are achieved.

    摘要： Provided is a shortening clutch with which it is possible to improve operability when removing a chain link. A shortening clutch 10 is provided with a main body 20 provided with a pocket 30 for accommodating a first chain link C21 of another chain C2, and a lock lever 60 which is capable of switching between a locked state and an unlocked state by pivoting, and which restricts disengagement of the first chain link C21 from the pocket 30 in the locked state, and allows the first chain link C21 to disengage from the pocket 30 in the unlocked state, which is resisted by an urging force of an urging member, wherein the lock lever 60 is provided with a locking piece 65 which projects from a pivot point toward the pocket 30 side, facing a position in which movement of a second chain link C22 in an escaping direction is restricted, a first operating piece 62 extending to the side of the pivot point on which one chain C1 is coupled, and a second operating piece 63 extending to the opposite side.
