PROBLEM TO BE SOLVED: To provide an elevator having no machine room enabling space utilization more efficient than before within a building and an elevator shaft. SOLUTION: In an elevator, preferably an elevator having no machine room, a winding machine is engaged with hoisting ropes by a pair of traction sheaves 1. This set of the hoisting ropes substantially comprises a plurality of hoisting ropes having a circular cross section. The hoisting ropes support a counter weight and an elevator car to each running path thereof. The hoisting ropes have thickness below 8 mm, and/or the diameter of the traction sheave is below 320 mm. The contact angle between the hoisting ropes and the traction sheave is 180 degrees or more. COPYRIGHT: (C)2003,JPO

PROBLEM TO BE SOLVED: To provide a new type hold brake for traction elevator. SOLUTION: This hold brake for traction sheave elevator comprises a brake main body 1, a brake shoe 2 attached to the brake main body 1, a pulling back means 4 letting the brake shoe 2 leave a brake wheel 5, and a mechanical pressing element 6 pressing the brake shoe 2 against the brake wheel 5. Furthermore, the hold brake comprises an intermediate frame 7 arranged between the brake main body 1 and the brake shoe 2, and the pressing element presses the intermediate frame 7. In addition, the hold brake includes an adjusting element 8 between the intermediate frame 7 and the brake shoe 2 so that a relative position of the brake shoe 2 for the intermediate frame 7 can be adjusted when an air gap between the brake shoe 2 and the brake wheel 5 is adjusted.
Abstract:
People mover (1), more particularly a travelator or corresponding, which comprises a plurality of steps or corresponding for carrying and moving people, a transmission chain formed into an endless loop, which transmission chain is connected to the aforementioned steps or corresponding, and via which transmission chain the steps or corresponding are moved, and which transmission chain comprises consecutive chain links, which are connected in a hinged manner to each other such that the chain links are able to bend in relation to each other in a first direction (I) and in a second direction (II), and which' transmission chain is arranged to pass around at least two turning elements (5,6), when passing around which the consecutive chain links of the transmission chain bend in relation to each other in the first direction. The transmission chain comprises means for limiting bending of the transmission chain occurring in the second direction (II).
Abstract:
Elevator without counterweight, in which elevator there is a compensating system separating the roping portion of the hoisting ropes above the elevator car from the roping portion of the hoisting ropes below the elevator car and in which the rope tension is arranged by means of the compensating system to be greater in the portion of roping above the elevator car than in the portion of roping below the elevator car, installed by raising the travel height of the elevator at least once. When raising the travel height, the extension of the hoisting ropes is fed in via the compensating system or via the rope fastening in the compensating system.
Abstract:
The invention relates to an elevator and an elevator hoisting machine, said hoisting machine comprising at least a frame (19) secured to at least one guide rail (10) in the elevator shaft and containing a stator and a fixed assembly consisting of at least a traction sheave (7) and a rotor frame, said assembly being mounted with bearings so as to be rotatable with respect to the frame (19), and which hoisting machine is secured to a stiffener (23) reinforcing the frame (19). The stiffener (23) is secured by means of a fixing element (18) to at least one guide rail (10). The fixing element (18) is secured to the stiffener (23) substantially above the traction sheave (7) and substantially inside the vertical volume formed by the cross-section of the traction sheave.
Abstract:
An elevator, which preferably is an elevator without counterweight and in which an elevator car is suspended by means of a set of hoisting ropes comprising one rope or a number of parallel ropes. The elevator has a traction sheave that moves the elevator car by means of the hoisting ropes. The elevator comprises rope portions of hoisting ropes going upwards and downwards from the elevator car, and the elevator has a compensating device acting on the hoisting ropes to equalize and/or compensate rope tension and/or rope elongation. The compensating device acting on the hoisting ropes of the elevator comprises at least one slack rope prevention means for preventing uncontrolled slackening of the hoisting ropes and/or uncontrolled motion of the compensating device.
Abstract:
A stator fastening arrangement in a flat elevator motor (2) having a motor body (4) in which are arranged a stator (5) comprising a stator core (51) and a winding (52), and a rotor (7) fitted in conjunction with the stator. The stator (5) is fitted within a substantially trough-like mounting part (9) fastened to the motor body (4), and the space between the mounting part (9) and the stator (5) is filled with a thermally conductive filling material (12) serving to conduct heat from the stator to the mounting part (9).
Abstract:
The object of the invention is an arrangement in the overspeed governor of an elevator, which elevator comprises at least one safety gear (12b) disposed in connection with the elevator car (1) as well as an overspeed governor (10). The overspeed governor comprises at least an overspeed governor pulley (12), the rope (11) of the overspeed governor and also a frame (13) and a locking element (15) with its axis of rotation (20) for stopping movement of the overspeed governor rope (11), which locking element (15) is arranged to turn around its axis (20) when the overspeed governor trips. The overspeed governor (10) further comprises permanent magnets (17) for forming a magnetic field. When the overspeed governor trips, the locking element (15) is arranged to move, in addition to its turning movement, essentially in the direction of the radius of its axis of rotation (20).
Abstract:
The invention relates to a method and an apparatus for changing the direction of motion of a pallet (1) moving on wheels (5a, 5b, 6a, 6b) in a travelator or equivalent, in which travelator or equivalent the pallets moving in the traveling direction move at a different level than the pallets moving in the return direction and the direction of motion of the pallets is changed at the end of the travelator or equivalent keeping the pallet continuously in substantially the same orientation during the direction change. During direction change the trailing end of the pallet (1) as seen in the traveling direction is guided by positive control from one level of the traveling direction to the other level by utilizing a supporting element (8) supporting the pallet by a wheel of the pallet, said supporting element (8) being positioned by means of a positioning device (26) into an advantageous position for meeting the wheel of the pallet.
Abstract:
The invention relates to a travelator, which comprises a conveyor (1) comprising a number of belt drums (2, 3, 4) . Placed at the end (6) of the conveyor is a first belt drum (2) . A second belt drum (3) is the one next to the first belt drum. A third belt drum (4) is one of the following belt drums adjacent to the second belt drum. The conveyor further comprises a number of mutually parallel endless belt loops (7, 8) forming a conveying surface (9). The first belt loops (7) are passed over the belt pulleys on the first belt drum (2) and on the second belt drum (3). The second belt loops (8) are passed over the belt pulleys on the second belt drum (3) and the third belt drum (4) so that they are alternately interleaved with the first belt loops. A comb plate (10) is arranged in the immediate vicinity of the end (6) of the conveyor. The comb plate (10) has a number of teeth (11) substantially parallel to each other and spaced by a distance, the first belt loops (7) being fitted to pass between said teeth, and an upper surface (12). The upper portions of the first belt loops (7) are at an inclined angle (a) The comb plate (10) is so disposed on the first belt drum (2) that the teeth (11) of the comb plate (10) extend substantially close to the second belt loops (8) running over the second belt drum (3).
