  • Publication number: 20210061614
    Abstract: A method for determining a degraded guide rail condition in an elevator system, a computer program product, and an elevator system are disclosed. The method includes obtaining first data including information about movement of an elevator component relative to a guide rail, and obtaining second data including information about movement of an elevator component. The method further includes comparing the first data and the second data to each other, and detecting, based on the comparison, a deviation fulfilling a deviation criterion. Still further, the method includes creating a signal indicating the degraded, such as misaligned, guide rail condition, such as of the first or the second guide rail.

  • Publication number: 20210016999
    Abstract: The present invention relates to a conveyor system comprising: a drive machine, a conveyor control unit configured to control operation of a conveyor device, a sensor array comprising at least one sensor mounted to the drive machine and adapted to measure one or more properties of the drive machine, a processing unit associated with the drive machine, wherein the processing unit is connected to the sensor array and configured to obtain and process measurement data from the sensor array to generate in-formation about an operation of the drive machine, and a communication channel between the conveyor control unit and the processing unit. The conveyor system may be an elevator system, an escalator system or a moving walk system.

  • Publication number: 20200339381
    Abstract: The invention relates to a method for operating an elevator system. The method comprises receiving a request to drive an elevator car to a destination and generating an elevator car motion profile to serve the received request. The elevator car motion profile comprises at least the following motion parameters of the elevator car: acceleration, maximum speed, and deceleration. At least one of the maximum speed of the elevator car and the deceleration of the elevator car in the generated elevator car motion profile is defined on the basis of the destination. The invention relates also to a processing unit and an elevator system configured to perform the method at least partly.

  • Publication number: 20200283269
    Abstract: An element includes a vibration isolation pad with two opposite substantially planar surfaces, an elastic material layer being permanently attached to a first of the two substantially planar surfaces of the vibration isolation pad, a load sensor arrangement integrated into the combined elevator vibration isolation and load measurement element. A load acting on the combined elevator vibration isolation and load measurement element can be measured with the load sensor arrangement as a function of the compression of the elastic material layer.

  • Publication number: 20200207575
    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.

  • Publication number: 20200207582
    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.

  • Publication number: 20200062545
    Abstract: An elevator safety brake unit, an elevator including at least two of the safety brake units, and a method for testing the safety brake units are disclosed. Each safety brake unit includes a frame part, a movable composition movably supported on the frame part, a compression spring assembly associated with the movable composition, and adapted to activate a braking by pushing the movable composition forward, and a coil assembly of an electromagnet disposed in the frame part and adapted to deactivate the braking by pulling the movable composition backwards. Each movable composition includes at least two movable elements, one compression spring for each movable element, and at least one coil assembly adapted to deactivate the braking by pulling the at least two movable elements backwards.

  • Publication number: 20190315593
    Abstract: An elevator brake includes a frame part including an electromagnet; a moving armature movably supported on the frame part; at least one energy storage, such as a work spring, arranged between the frame part and the moving armature; a friction lining associated with the moving armature and fitted to engage a braking surface with a normal force originating from the at least one energy storage, to brake movement of an elevator car or to hold the elevator car standstill; and a sensor system including one or more sensors mounted into the elevator brake and adapted to sense one or more operational parameters of the elevator brake and/or to directly measure normal force of the friction lining.
