Abstract:
A platform assembly includes a first platform module having an elongated front face, a second platform module having an elongated front face, and a locking member for locking the front faces of the first and second platform modules to each other. The locking member is movably mounted on the first platform module in a longitudinal direction of the front face thereof, and at least one of the locking member and the second platform includes a locking protrusion, and the other of the locking member and the second platform includes a locking slot, wherein the locking protrusion is received by the locking slot and protrudes from the front face of the first platform module. An edge of the locking protrusion is 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 a method for controlling an elevator system. The method comprises causing transmission of radio frequency signals with at least one radio frequency sensor attached to at least one element movable in an elevator shaft of an elevator system, receiving, from the at least one radio frequency sensor measurement data representing radio frequency signals reflected from at least one object and captured with the at least one radio frequency sensor, causing identification, based on the measurement data, of at least one object; and controlling operation of the elevator system in response to identifying the at least one object based on the measurement data.
Abstract:
The disclosure relates to a method for detecting an impact on an elevator door. The method is characterized in that it comprises detecting a break in an elevator door safety circuit; comparing characteristics of the break to a set of parameters; and performing an action when the characteristics of the break fulfil the conditions determined by the set of parameters. The disclosure further relates to an apparatus, to an elevator safety system and to an elevator.
Abstract:
A method for controlling an elevator installed in a building that includes an elevator car arranged to travel in a hoistway between floor landings that are at different heights, one or more ropings connected to the elevator car, a hoisting machine for moving the elevator car, and a control for control the hoisting machine is provided. In the method, the sway data of the building is determined, which data describes the strength of the sway of the building, and the starting position data of the elevator car is determined, which starting position data contains data about the starting position of the elevator car and/or data about how long the elevator car has been in the starting position, and the settings for the run speed of the next run are determined on the basis of the starting position data and the sway data. An elevator is configured to perform the method.
Abstract:
A method for generating maintenance data of an elevator door system includes detecting a first event during closing or opening of a door of the elevator door system and defining a time stamp of the first event, wherein the first event is opening or closing of a safety circuit; detecting at least one second event during said closing or opening of the door of the elevator door system and defining time stamp of the at least one second event; defining a difference value by comparing the time stamp of the first event and the time stamp of the at least one second event; comparing the difference value to previously stored one or more difference values; and generating maintenance data of the elevator door system. A system is provided to perform at least partly the method.
Abstract:
The invention relates to a method for transporting construction material and/or equipment inside a building under construction, wherein the building under construction comprises plurality of vertically displaced floors, the method comprising providing an elevator for transporting transport containers in the building under construction, said elevator comprising at least a load receiving unit vertically movable along one or more guide rail lines in an elevator shaft formed in the building under construction; and providing plurality of transport containers each comprising a container body, and an identification provided on the container body for identifying the container and/or its destination in the building, most preferably the destination floor in the building under construction; providing one or more detectors within the building under construction for detecting identifications of containers when they are within the detection ranges of the one or more detectors; moving a first transport container belonging to said plurality of transport containers to a loading floor; loading the first transport container belonging to said plurality of containers on the load receiving unit; determining by a control system destination floor of the first container comprising detecting the identification of the first transport container with a detector; automatically moving the load receiving unit vertically in the elevator shaft to the destination floor of the first container; and unloading the first transport container from the load receiving unit to the destination floor of said first container. The invention also relates to a method for constructing a building and an arrangement, which implement the aforementioned method.
Abstract:
The current disclosure relates to a power system for feeding power into a vertical transportation arrangement. The power system comprises a first interface for connecting to a primary power source; a second interface for connecting to a secondary power source; and power controlling means for controlling feeding of power from the primary power source and/or the secondary power source to a motor for driving a vertical transportation device. The power system is characterized in that the power controlling means is configured to control feeding at least some of the power used by the motor during normal operation from the secondary power source. The current disclosure also relates to a method and vertical transportation arrangements.
