Abstract: According to an aspect, there is provided an elevator car parking brake comprising a brake carrier having a first plate and a second plate, the plates being spaced from each other and positioned to enable a guide rail to travel within the space between the plates, a caliper movably connected to the brake carrier, brake pads, and an actuator configured to move the brake pads against a guide rail in a braking operation. The elevator car parking brake further comprises at least one first compression spring arranged between the first plate of the brake carrier and a brake pad directly associated with the actuator; and at least one second compression spring arranged between the second plate of the brake carrier and the caliper, the first and second compression springs being configured to keep the brake pads substantially centered with respect to the brake carrier.

Abstract: According to an aspect, there is provided an elevator car parking brake comprising brake pads and an actuator configured to move the brake pads with respect to a guide rail. The elevator car parking brake further comprises levers, each having an associated brake pad; and at least one screw associated with the actuator and rotatably fixed to at least one lever via at least one attaching member. In a braking operation, the actuator is configured to rotate the at least one screw in a first direction with respect to the at least one attaching member, thus causing the levers with the brake pads to move towards the guide rail. In a brake release operation, the actuator is configured to rotate the at least one screw in a second direction with respect to the at least one attaching member, thus causing the levers with the brake pads to move away from the guide rail.

Abstract: A rope storage unit includes a rope reel, formed by a rope wound in a spiral form and a support body provided with an inner space inside which the rope reel is positioned supported by the support body. 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. The support body includes one or more support members delimiting the inner space and surrounding radially the rope reel. The outer rim of the rope reel radially compresses against the one or more support members as an effect of the bending tension. A method is provided for installing an elevator rope implementing the rope storage unit, as well as to a method for fabricating the rope storage unit.

Abstract translation: 绳索存放单元包括由缠绕成螺旋形的绳索形成的绳索卷轴和设置有内部空间的支撑体，在该内部空间中绳索卷轴由支撑体支撑定位在该内部空间内。 绳索是在静止状态下具有直的形状的杆，并且可以从直的形式弹性弯曲，绳索处于螺旋形状的实质弯曲张力。 支撑体包括限定内部空间并围绕绳索卷轴径向的一个或多个支撑构件。 作为弯曲张力的作用，绳卷轴的外缘径向地压靠在一个或多个支撑构件上。 提供一种用于安装实施绳索存放单元的电梯绳索的方法以及用于制造绳索存放单元的方法。

Abstract: According to an aspect, there is provided an elevator parking brake comprising brake pads configured to provide a braking force against a guide rail in a loading and unloading situation of an elevator car; and at least one sensor. The elevator parking brake is configured to allow a predetermined amount of movement within the elevator parking brake in the loading and unloading situation of the elevator car, and the at least one sensor is configured to provide at least one indication associated with the movement within the elevator parking brake in the loading and unloading situation of the elevator car.

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.
