Abstract
The structure and operation of a brake' associated with an electric motor driven chain hoist′, according to FIG., are exactly the same as those of the manually operated system, except that a shaft′ of the electric motor rotor′ as well as an extension′ thereof form a drive shaft and the second cam part 6, the brake disc/clutch disc arrangement, a driven input shaft′ of a hoisting apparatus′ and the hoisting apparatus′ itself are arranged between an electric motor′ and the first cam parton the drive shaft′ in such a manner that the second cam partwith the componentsfastened thereto may rotate therein and move axially and the input shaft′ of the driven hoisting apparatus′ may rotate, since the rotor′ is placed on the opposite side of the system compared with the manually operated system shown in FIGS.toso that the extension′ of the shaft′ of the rotor′ has to move through the input shaft′. Parts′ and′ of a body′ of the brake are also shaped differently but operate similarly.
