Abstract:
A travelator system for conveying a passenger, comprising a main conveyor and a branch conveyor. The main conveyor includes a first plurality of shafts each having a first plurality of belt pulleys disposed side by side thereon. The main conveyor also includes a plurality of mutually parallel endless belt loops which define a moving conveying surface of the main conveyor, each belt loop being passed over a belt pulley on two different shafts. Adjacent belt loops on the same common shaft are passed over different belt pulleys such that a first belt loop is passed over a belt pulley on a previous shaft relative to the common shaft in a transport direction of the main conveyor, while a second belt loop is passed over a belt pulley on a following shaft relative to the common shaft in a transport direction of the main conveyor. The branch conveyor branches off of the main conveyor in a connecting section to allow passengers to enter from the branch conveyor onto the main conveyor and/or to exit from the main conveyor onto the branch conveyor. The branch conveyor is also implemented using shafts, belt pulleys, and belt loops similar to the main conveyor. In the connecting section, the branch conveyor and the main conveyor share at least one common shaft.
Abstract:
An arrangement for a people mover located near a floor surface comprises a transport conveyor structure including a conveyor and a handrail having a casing. A drive machine is operatively arranged at least for moving the conveyor and the handrail. The drive machine is located above the floor surface and is installed in the transport conveyor structure, at least partly inside the casing of the handrail.
Abstract:
The invention relates to an elevator and a method for adjusting the inter-car distance in an elevator which comprises two or more elevator cars coupled to each other so as to be movable together in an elevator shaft, and in which these elevator cars are at least partly suspended by means of a common set of hoisting ropes (2). The vertical inter-car distance between the elevator cars (6 and 7) is adjusted by moving at least one of the elevator cars (6 or 7) in relation to at least one other elevator car (6 or 7) by pulling the elevator car to be moved upwards and lowering the elevator car to be moved downwards by means of at least one adjusting rope (13).
Abstract:
Traction sheave elevator without counterweight and method for braking an elevator, in which elevator the elevator car is suspended by means of hoisting ropes consisting of a single rope or several parallel ropes, said elevator having a traction sheave which moves the elevator car by means of the hoisting ropes. In the elevator, when the elevator car is moving upwards in an emergency stop situation the braking of the operating brake of the elevator is at least partially prevented for at least a part of the stopping distance of the elevator.
Abstract:
An elevator in which the elevator car is suspended by means of hoisting ropes consisting of a single rope or several parallel ropes, said elevator having a traction sheave which moves the elevator car by means of the hoisting ropes. The elevator has rope portions of the hoisting ropes going upwards and downwards from the elevator car, and the rope portions going upwards from the elevator car are under a first rope tension (T1) which is greater than a second rope tension (T2), which is the rope tension of the rope portions going downwards from the elevator car, and that the elevator comprises a compensating system for keeping the ratio (T1/T2) between the first and the second rope tensions substantially constant.
Abstract:
An arrangement for coupling a pallet in a conveying device includes a pallet having wheels and forming a part of a transport track of the conveying device, and a drive element. A coupling piece is adapted to be connected to the pallet and a fastening parties connects the drive element to the coupling piece.
Abstract:
The invention relates to a method and apparatus for adjusting the inter-car distance in a double-deck elevator provided with hoisting ropes (2), in which elevator the hoisting ropes (2) move a car frame (3) supporting the elevator cars (6 and 7) along guide rails (5). The vertical inter-car distance between the elevator cars (6 and 7) is adjusted by moving at least one of the elevator cars (6 or 7) in relation to the car frame (3) by pulling the elevator car to be moved upwards and lowering the elevator car to be moved downwards by means of an adjusting rope (13).
Abstract:
Arrangement for mounting the stator winding in the stator of the electric motor of an elevator machine, said stator comprising a stator frame (1) provided with stator teeth (11) and slots (12) between them, the stator winding (2) being fitted in said slots (12), said stator having fastening elements fitted in the slots for fastening the stator winding to the slots. The stator comprises a winding frame (3) having a bottom (31) placed against the slot and sides (32), in which winding frame the winding can be fitted, and the winding frame comprises flexible locking elements (33) projecting from the bottom, which locking elements can be fitted into holes (13) provided in the slots and which, when the winding frame is being pushed into the slot, are inserted into the holes and lock the winding frame and the stator winding to the stator frame.

Stator winding in the stator of the electric motor of an elevator machine, said stator comprising a stator frame (1) provided with stator teeth (11) and slots (12) between them, the stator winding (2) being fitted in said slots (12). The stator comprises a winding frame (3) having a bottom (31) facing against the slot and sides (32), in which winding frame the winding can be fitted, and it has strip-like or stick-like elements (4) of ferromagnetic material fitted at the mouths of the slots (12) to control the magnetic flux.
Abstract:
Elevator arrangement for setting the starting torque of the motor of an elevator machinery, the elevator machinery being mounted on a guide rail in an elevator shaft. The elevator arrangement has at least one power sensor for determining the imbalance moment that the car load produces in the elevator machinery.
