Abstract:
The invention relates to a brake (1), which comprises : a frame part (2); an armature part (3) supported by the frame part in a manner that allows movement; an electromagnet (5) for opening the brake; and also a damping arrangement (4) for damping the noise of the brake. The aforementioned damping arrangement (4) is made to be conductive to magnetic flux, and the aforementioned damping arrangement (4) is fitted on the pathway of the magnetic flux of the electromagnet (5) of the brake.

Abstract:
The invention presents a method and an arrangement for preventing the drifting of an elevator car (1) away from the stopping floor (10). In the method: a) the operating condition of one or more machinery, brakes (3) of the hoisting machine (2) of the elevator is monitored regularly b) the elevator car leaving the door zone (4) of the stopping floor (10) is stopped when the door (6) of the elevator car and/or the landing door (37) is/are open by using the aforementioned one or more machinery brakes (3) of the hoisting machine c) starting of the next. run of an elevator car (1) that has left the door zone (4) of the stopping floor (10) when the door (6) of the elevator car and/or the landing door (37) is/are open is prevented, and d) information about the drive prevention is recorded in the non-volatile memory (9) of elevator control unit (8).

Abstract:
Rail brake (1) for an elevator, comprising a brake body attached to the elevator car, a clamp part comprising jaws (3,4) that engage a guide rail (2) via braking surfaces during braking. A spring (10) generates a load on the clamp part to press the braking surfaces against the guide rail, and a magnet whose force produces an effect reverse to that of the spring releases the braking surfaces from the guide rail. The clamp part is floatably suspended relative to the brake body. The motion of the clamp part relative to the brake body is controlled by the guide rail (2).
Abstract:
The invention relates to a method for transporting construction material and/or equipment into and inside a building (1) under construction, wherein the building (1) under construction comprises plurality of vertically displaced floors (F0-Fn), the method comprising providing a control system (11) configured to automatically operate one or more transporting devices (2-6, GE), including at least an elevator (GE); providing a storage (8) at the construction site of the building; and transporting into the storage (8) at the construction site of the building (1) under construction plurality of transport containers (9) containing construction material and/or equipment; storing said transport containers (9) in the storage (8); and delivering transport containers (9) belonging to said plurality of transport containers from said storage (8) to different destination floors (F1-Fn), the delivering comprising obtaining an order to deliver a transport container (9), the order identifying the transport container (9) to be delivered; and retrieving the transport container (9) identified in the order from the storage (8); and moving said transport container (9) at least horizontally to a container loading floor (FO) of the building (1) under construction; and loading said transport container (9) on the load receiving unit (7) for being moved to its destination floor; and obtaining the destination floor information indicating the destination floor of said container (9); and moving the load receiving unit (7) vertically in the elevator shaft (S) to the destination floor of said transport container (9); and unloading said transport container (9) from the load receiving unit (7) to the destination floor of said transport container (9). The invention also relates to a method for constructing a building and an arrangement for transporting construction material, which implement the method for transporting construction material and/or equipment into and inside a building (1) under construction.
Abstract:
Abstract The invention relates to a method for modernizing an elevator system, which elevator system comprises a first elevator (1) comprising a first car (2) in a first hoistway (3), a second elevator (4), comprising a second car (5) in a second hoistway (6), the method comprising using the first and second car (2,5) for transporting passengers and/or goods between vertically displaced floors of a building (7), and thereafter removing the first elevator car from use for transporting passengers and/or goods between vertically displaced floors, and thereafter installing a construction time elevator (8) into the lower end of the first hoistway (3), the traveling zone (Z3) of the car (9) of the construction time elevator (8) covering only partially the height of the first hoistway (3); and thereafter using the car (9) of the construction time elevator (8) and the second car (5) simultaneously for transporting passengers and/or goods between vertically displaced floors of the building (7), during which using the method comprises performing construction work in the first hoistway (3) above the traveling zone (Z3) of the car (9) of the construction time elevator (8); and thereafter changing the traveling zone (Z3) of the car (9) of the construction time elevator (8) to extend higher (Z5) in the hoistway (3), and thereafter using the car (9) of the construction time elevator (8) and the second car (5) simultaneously for transporting passengers and/or goods between vertically displaced floors, during which using the method comprises performing construction work in the first hoistway (3) above the traveling zone (Z5) of the car (9) of the construction time elevator.
