Abstract
An elevator and a locking apparatus for preventing rotational movement of the traction sheave of the elevator are provided. The elevator includes at least a hoisting machine provided with a traction sheave, a frame and at least one brake. A holding device is disposed in connection with the hoisting machine, which holding device is arranged to prevent rotational movement of the traction sheave.
Claims9
A locking apparatus to limit movement of an elevator car, the locking apparatus comprising a base formed by a frame part and a holding device configured to limit movement of the elevator car, wherein the locking apparatus is disposed with respect to a hoisting machine such that the holding device of the locking apparatus is arranged to limit rotational movement of the traction sheave, wherein the holding device pivots about an axis that is perpendicular to a rotational axis of the traction sheave to meet a holding detent on the traction sheave, and wherein the base of the locking apparatus is fixed to the frame of the hoisting machine.
A locking apparatus to limit movement of an elevator car, the locking apparatus comprising a base formed by a frame part and a holding device configured to limit movement of the elevator car, wherein the locking apparatus is disposed with respect to a hoisting machine such that the holding device of the locking apparatus is arranged to limit rotational movement of the traction sheave, wherein the holding device pivots about an axis that is perpendicular to a rotational axis of the traction sheave to meet a holding detent on the traction sheave, and wherein the holding device is fixed to the base on the frame by means of a hinge.
A locking apparatus to limit movement of an elevator car, the locking apparatus comprising a base formed by a frame part and a holding device configured to limit movement of the elevator car, wherein the locking apparatus is disposed with respect to a hoisting machine such that the holding device of the locking apparatus is arranged to limit rotational movement of the traction sheave, wherein the holding device pivots about an axis that is perpendicular to a rotational axis of the traction sheave to meet a holding detent on the traction sheave, and wherein the base comprises a groove, into which the holding device is arranged to turn in a locking phase of the traction sheave.
A locking apparatus to limit movement of an elevator car, the locking apparatus comprising a base formed by a frame part and a holding device configured to limit movement of the elevator car, wherein the locking apparatus is disposed with respect to a hoisting machine such that the holding device of the locking apparatus is arranged to limit rotational movement of the traction sheave, wherein the holding device pivots about an axis that is perpendicular to a rotational axis of the traction sheave to meet a holding detent on the traction sheave, and wherein the base comprises a locking device, which is arranged to prevent an exit of the holding device from a groove of the base.
