Abstract: A rope storage unit for storing an elevator rope during transportation and/or installation of the elevator rope includes a rope reel, formed by a rope wound in a spiral form and having a central axis; and a support frame provided with an inner space inside which the rope reel is positioned supported by the support frame such that it can in use be rotated in the inner space for unwinding the rope. The rope is a rod having a straight form when in rest state and elastically bendable away from the straight form, the rope being under substantial bending tension in the spiral form, and wherein the support frame comprises three or more rotatable support rollers delimiting the inner space and surrounding radially the rope reel. A method for installing an elevator rope implements the rope storage unit.

Abstract: According to an aspect, there is provided an elevator car parking brake. An operating fork is configured to move within a housing in a direction perpendicular to an end surface of a guide rail in response to operating an actuator. When the actuator is operated to move the operating fork within the housing towards the guide rail to achieve a braking state, the operating fork is configured to push braking wedges towards side surfaces of the guide rail to contact the side surfaces. When the actuator is operated to move the operating fork within the housing away from the guide rail to achieve a brake release state, detaching means are configured to pull the braking wedges away from the side surfaces of the guide rail.

Abstract: A pulley wheel rack includes a first rack part and a second rack part; a pulley wheel space between the first rack part and the second rack part; a first frame arranged to the first rack part, and a second frame arranged to the second rack part; an axle configured to extend from the first frame to the second frame, and configured to be rotatable into different securable positions by a ball joint arranged into the first frame and the second frame; and a pulley wheel bearing-mounted on the axle by hub bearings, and including at least one traction surface for engaging an elevator rope. A method for aligning a pulley wheel in a pulley wheel rack is also disclosed.

Abstract: The invention relates to rope gripping member for a rope gripping device, the rope gripping member comprising an elongated rope gripping face for being pressed against an elongated side face of an end section of a rope, the elongated rope gripping face having a longitudinal direction and a front edge and a rear edge; wherein tensile stiffness of the rope gripping member in longitudinal direction of the gripping face increases non-linearly with accelerating rate from the front edge towards the rear edge of the gripping face. The invention also relates to a rope gripping device, a rope terminal arrangement and a hoisting apparatus implementing the rope gripping member.
