An elevator car or counterweight, comprising a frame, the frame including an upright structure in which a safety brake is mounted so as to allow for lateral movement of the safety brake relative to the upright structure; at least a first vertically or obliquely extending cantilever spring; wherein a first end of the first cantilever spring is mounted to the upright structure; and wherein the first cantilever spring is arranged such that a point remote from the first end provides a biasing force to the safety brake when the safety brake moves away from a default position. As the safety brake is mounted to allow for lateral movement relative to the frame, the safety brake essentially floats relative to the car or counterweight.

Mounting apparatus for safety brake

A method of resetting a braking device includes moving an elevator car upward, sliding a support member coupled to the braking device relative to the elevator car, and moving a brake wedge of the braking device along a sloped slide path.

Elevator braking device mechanism

A support member of a braking device includes a body configured to couple to the braking device. The body has a first portion including a first inclined body surface and a second inclined body surface. The first portion is receivable within an opening having a first inclined opening surface and second inclined opening surface. The first inclined body surface is complementary to the first inclined opening surface and the first portion of the body is movable within the opening.
