Abstract:
An arrangement and a method for changing a direction of movement of an elevator car of an elevator, and the elevator thereof, are presented. The arrangement comprises at least two rotatable first stator beam parts for receiving at least two movers rotatably coupled to the elevator car and at least one actuator for rotating the at least two first stator beam parts. Said stator beam parts are arranged such that the axes of rotation of said stator beam parts align with the axes of rotation of the movers when the movers are arranged at corresponding positions. Each one of the movers rotates along with a respective first stator beam part when said respective first stator beam part is being rotated by the at least one actuator.
Abstract:
A drive machine for an elevator includes a motor module including at least a motor, a drive shaft, and a first transmission wheel, which are provided with a common rotational axis and connected coaxially to each other. The drive machine further includes a traction module including at least a traction wheel engageable with elevator hoisting ropes, and a second transmission wheel, which are provided with a common rotational axis and connected coaxially to each other. The motor module and the traction module are positioned side by side with their rotational axes parallel, such that the traction wheel and the drive shaft are side by side, and the first and second transmission wheels are side by side. The drive machine further includes an endless drive member passing around the first and second transmission wheels. An elevator comprising said drive machine is also disclosed.
Abstract:
A platform assembly includes a first platform module having an elongated front face, a second platform module having an elongated front face, a locking member for locking the front faces of the first and second platform modules to each other when they are set against each other, which locking member is movably mounted on the first platform module. The locking member is mounted on the first platform module movably in the longitudinal direction of the front face of the first platform module, and at least one of the locking member and the second platform includes a locking protrusion protruding from the front face of the platform module, and the other of the locking member and the second platform includes a locking slot arranged to receive the locking protrusion when the front faces of the platform modules are set against each other, and an edge of the locking protrusion is arranged to move behind an edge of the locking slot when the locking member is moved in said longitudinal direction of the front face, thereby locking the platform modules to each other.
Abstract:
According to an aspect, there is provided an elevator system comprising an elevator car configured to move in an elevator shaft; a counterweight associated with the elevator car, the counterweight configured to move in the elevator shaft; a compensation member coupled to the elevator car and the counterweight, the compensation member being diverted by a compensation pulley disposed in an elevator pit; and a manual rescue device disposed in the elevator shaft being mechanically coupled to the compensation member, the manual rescue device comprising an interface configured to receive a tool to operate the manual rescue device. A rotating axis of the manual rescue device is disposed in the elevator shaft at a location corresponding to an opening in the lowest landing floor to enable operation of the manual rescue device with the tool via the opening to move the elevator car in a rescue situation.
