Abstract:
The object of the invention is an elevator car intended for transporting people and freight, in an elevator wherein the elevator car is supported resting on suspension members and arranged movably in an elevator hoistway when moved by a hoisting machine. At least the floor and roof of the elevator car are composed of dimensionally precise modular elements fabricated by casting, extruding and/or pressing into their shapes and dimensions.
Abstract:
The object of the invention is an elevator provided with a safety apparatus arrangement, which elevator comprises at least an elevator car traveling along guide rails and a safety brake device, such as a safety gear, for stopping undesired movement of the elevator car, as well as a transmission mechanism for activating the safety gear. The safety apparatus arrangement comprises a tuning apparatus disposed on the elevator car for detecting a presence on the roof of the elevator car, which tuning apparatus comprises means for pre-activating the transmission mechanism when a presence on the roof of the elevator car has been detected.
Abstract:
The object of the invention is an elevator provided with a safety device arrangement, which elevator comprises at least an elevator car traveling along guide rails and a safety brake device for stopping unintended movement of the elevator car. The safety device arrangement comprises a tuning apparatus disposed on the elevator car for detecting a presence on the roof of the elevator car.
Abstract:
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.
Abstract:
The invention relates to a method and arrangement for installing an elevator, which comprises an elevator car arranged to run in an elevator shaft along the guide rails, a balancing weight connected to the elevator car with suspension ropes and with a traction member, the elevator comprising further a hoisting machinery with a driving wheel in the lower part of the elevator shaft below the elevator car, the installing comprising one or more jumps to make the elevator serve higher floors. During the jump phase extensions needed for the suspension ropes are taken from first supply reels and extensions needed for the traction member are taken from second supply reels.
Abstract:
An elevator includes at least an elevator car arranged to move reciprocally in an elevator hoistway and fitted on guide rails, a plurality of landing doors having landing door locks openable e.g. with a service key, and a safety arrangement arranged to form a safe space, preferably a working space, in the elevator hoistway below the elevator car, access to which safe space is enabled via at least one landing door in the proximity of the base of the elevator hoistway, and/or a safe space, preferably a working space, above the elevator car, to which access is enabled via at least one landing door leading to the roof of the elevator car, and in which elevator the aforementioned safe space has a minimum height. The formation of each safe space is arranged to be implemented as a consequence of the opening occurring, e.g. with a service key, from a floor level of a landing door enabling access into the elevator hoistway.
