1. An elevator braking device, comprising:
a first brake member for applying a braking force to a first side of an element; a second brake member that is moveable relative to the first brake member for applying a braking force to a second side of the element; a brake release member adjacent the first brake member to be received against the first side of the element between the first brake member and the first side of the element, the brake release member being moveable relative to the first brake member for selectively releasing the elevator braking device from engagement with the element; and at least one guide pin, wherein
said brake release member is selectively movable relative to said first brake member on the at least one guide pin;said first brake member includes a first arm and a second arm;the brake release member is received between said first arm and said second arm;a top of the brake release member being beneath an upper one of said first arm and said second arm;a bottom of the brake release being above a lower one of said first arm and said second arm;one of said first arm and said second arm limits movement of said brake release member in a first direction beyond a selected position that corresponds to a position of the brake release member when the braking force is applied to the first side of the element; andthe other of said first arm and said second arm limits movement of said brake release member in a second, opposite direction. |
