An elevator may include an elevator car, a set of hoisting ropes, a hoisting machine, a traction sheave, and a brake. The elevator car may be suspended on the hoisting ropes. The hoisting machine may drive the traction sheave to move the elevator car using the hoisting ropes. The brake may include a brake wheel and brake shoes. The brake may exert an effect on rotation of the traction sheave. During braking, the effect of the brake on the rotation of the traction sheave may depend on a direction of rotation of the traction sheave. The effect of the brake on the rotation of the traction sheave may be greater when the direction of rotation of the traction sheave during braking corresponds to the elevator car moving downward than when the direction of rotation of the traction sheave during braking corresponds to the elevator car moving upward.
An arrangement for stopping an elevator car of an elevator, the elevator comprising the elevator car, a set of hoisting ropes, a hoisting machine, a traction sheave, and a brake that exerts an effect on rotation of the traction sheave, wherein the elevator car is suspended on the set of hoisting ropes, wherein the hoisting machine drives the traction sheave to move the elevator car using the set of hoisting ropes, and wherein the brake comprises a brake wheel and brake shoes, the arrangement comprising:
