BRAKE DEVICE AND ELEVATOR SYSTEM

A brake device is disclosed which has a function to adjust a speed of a hoisting machine, or stop the hoisting machine as a constituent element of an elevator system. The brake device includes: a rotating braked body having a rotary shaft interlocked with a rotation of the hoisting machine; a plurality of pads which are disposed on a surface of the rotating braked body in an attachable and detachable manner and have a function to give a braking force to the rotating braked body; and a plurality of calipers holding the pads. The plural calipers are structurally identical to each other, the pads have a pressing part to contact the surface of the rotating braked body and a recessed part not to contact the surface of the rotating braked body, and a position on the rotating braked body which contacts the pressing part of the pad in one of the calipers is different from a position on the rotating braked body which contacts the pressing part of the pad in another caliper. Thus, the frictional heat caused by the pads of the brake device can be reduced or dispersed, and also the calipers for holding the pads are made structurally identical so that assembling work and adjusting work can be easy.
