20130293019 | CONTROL ARRANGEMENT AND METHOD FOR SUPPLYING ELECTRICAL POWER IN AN ELEVATOR SYSTEM - A control arrangement and to a method for supplying electrical power in an elevator system are disclosed. The control arrangement includes a sensor detecting movement of an elevator car and also a control of the lighting of the elevator car. The control of the lighting of the elevator car is configured to control the emergency lighting of the elevator car on the basis of movement data of the elevator car expressed by the sensor detecting movement of the elevator car. | 11-07-2013 |
20130333982 | METHOD FOR MODERNIZING A HYDRAULIC ELEVATOR - A method for modernizing a hydraulic elevator including an elevator car guided by car guide rails for moving in an essentially vertical direction in the elevator hoistway, a hydraulic system including a lifting cylinder having a cylinder part essentially vertically supported on the base of the elevator hoistway and a piston rod moving in relation to the cylinder part and a hydraulic powerpack and a control center. The hydraulic system of the hydraulic elevator is modernized to include a function for preventing unintended starting at a floor, in such a way that the hydraulic powerpack is retained and an electrically-operating valve that is monitored with a control and that acts on the flow of hydraulic fluid of the lifting cylinder is added to the hydraulic system. The control controls a valve to prevent movement of the piston rod of the lifting cylinder downwards and/or upwards, if predetermined criteria are fulfilled. | 12-19-2013 |
20140034425 | ELEVATOR ARRANGEMENT - The object of the invention is an elevator arrangement, which comprises at least an elevator car configured to move up and down in an elevator hoistway and at least two compensating weights, which are for their part connected to support the elevator car by the aid of their own support means, such as by the aid of ropes or belts and also e.g. diverting pulleys, and a hoisting machine provided with at least one traction sheave or corresponding, and at least one traction means such as a rope or belt, which is configured to transmit the rotational movement of the traction sheave into movement of the elevator car and of the compensating weights. Each compensating weight is connected by the aid of a traction means to the same hoisting machine. | 02-06-2014 |
20140332326 | APPARATUS FOR FIXING A HOISTING MACHINE OF AN ELEVATOR AND A FIXING ARRANGEMENT - The object of the invention is an apparatus for fixing a hoisting machine of an elevator in an elevator comprising at least an elevator car configured to move reciprocally in an elevator hoistway and at least one or more counterweights or compensating weights, which are for their part connected to support the elevator car by the aid of at least one support member, such as by the aid of a rope or a belt, and also by the aid of diverting pulleys, and a hoisting machine provided with at least one traction sheave or corresponding, and also at least one or more traction members, such as a belt, a rope or a chain, which are configured to transmit the rotational movement of the traction sheave into movement of the elevator car guided by the guide rails and of the one or more counterweights or compensating weights guided by the counterweight guide rails or compensating weight guide rails. The apparatus comprises a machine station, comprising at least fixing points and means for fixing the traction sheave of the elevator, the motor and the diverting pulleys of the traction members into their position essentially precisely in relation to each other. | 11-13-2014 |
