Abstract:
An elevator parking brake, a method for operating an elevator parking brake, and a control device for an elevator parking brake are provided. The elevator parking brake includes a parking brake frame attachable to an elevator car, a brake pad configured to be brought in contact with a guide rail guiding the elevator car along an elevator shaft, and an actuating mechanism mounted on the parking brake frame, for bringing the brake pad in contact with the guide rail and retracting the brake pad from the guide rail. The actuating mechanism includes a motor, an actuating member and a conversion mechanism configured to convert a rotational movement of the motor into a linear movement of the actuating member. The actuating member brings the brake pad in contact with the guide rail and retracts the brake pad from the guide rail. The conversion mechanism includes a cam mechanism having a cam member driven to rotate by the rotational movement of the motor, wherein a driving profile of the cam member is in contact with the actuating member. The driving profile is configured to convert the rotational movement of the cam member into the linear movement of the actuating member.

The invention also relates to a method for constructing an elevator implementing the arrangement.
Abstract:
A construction arrangement of an elevator and a method for constructing an elevator. The construction arrangement of an elevator comprises a hoistway; at least one car guide rail and at least one counterweight guide rail mounted to the structure of the hoistway; an elevator car arranged movable on said at least one car guide rail; a counterweight arranged movable on said at least one counterweight guide rail; and a hoisting machine arranged above the counterweight; wherein the hoisting machine is mounted substantially between said at least one car guide rail and said at least one counterweight guide rail. The method for constructing an elevator comprising providing said construction arrangement, moving the hoisting machine from a first installation position to an upper second installation position in the hoistway, and mounting the hoisting machine substantially between said at least one car guide rail and said at least one counterweight guide rail.
Abstract:
The invention relates to an elevator arrangement comprising an elevator shaft wall; and a guide rail line extending vertically at a distance from the shaft wall, the guide rail line being fixed to said wall with plurality of fixing brackets; and an elevator car vertically movable along at least said guide rail line; and a hoisting machine mounted at a first vertical level between the shaft wall and the guide rail line; and a hoisting roping movable with said hoisting machine, and connected to the elevator car; wherein the guide rail line extends in vertical direction past the hoisting machine the upper end of the guide rail line being higher than said hoisting machine, and said plurality of fixing brackets comprises one or more first fixing brackets higher than said hoisting machine, by which one or more first fixing brackets the portion of the guide rail line which portion is higher than said hoisting machine is fixed to the shaft wall; and wherein the hoisting machine comprising a motor and a rotatable drive wheel. The elevator arrangement comprises an elongated hoisting passage extending vertically between the shaft wall and the guide rail line inside which hoisting passage the hoisting machine fits to be hoisted, each said first fixing bracket being shaped to circumvent the hoisting passage. The invention also relates to a method of constructing an elevator.
Abstract:
The invention relates to an elevator landing door assembly and a method for installing an elevator landing door. The landing door assembly comprises at least a landing door unit to be assembled to a landing door base opening having an upper edge, two side edges and a lower edge, which landing door unit comprises at least a top track and one or more door panels suspended by the top track through one or more supporting elements, and a door sill. The assembly comprises fixing elements in the landing door base opening equipped with receiving parts for fastening the landing door unit.
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 an elevator with an elevator car moving between landings at different levels in a first section of an elevator shaft. A second section located above the first section, the second section comprising a lifting device mounted under a crash deck and an installation platform which is movably suspended by the lifting device in the second section. At least one crash deck located between the first and the second sections.
Abstract:
A construction arrangement of an elevator, comprises a hoistway, a protection deck arranged within the hoistway for protecting the portion of the hoistway below it from falling objects, wherein the protection deck comprises: a frame mounted on stationary structure of the hoistway, a cover co-operating with the frame and extending across the hoistway, wherein the cover is adapted to protect the hoistway from falling objects and/or water from falling into the hoistway below it. The frame is, without dismantling it, configured to be increased and/or decreased in size, individually in at least one direction in relation to the corresponding adjacent stationary structure, such as wall, of the hoistway. A method for constructing an elevator comprises mounting a protection deck within a hoistway.
Abstract:
The invention relates to a rope anchor for anchoring one or more ropes of an elevator, comprising at least a wedge housing comprising a tapering nest shaped to have a narrow end which is open towards a first direction, and a wide end which is open towards a second direction; and one or more wedge members mounted in the tapering nest for being wedged against a rope passing through the tapering nest; and one or more spring members for urging and/or arranged to urge the one or more wedge member towards the narrow end of the tapering nest; and a releasing mechanism actuatable to move the one or more wedge members (2,3) towards the wide end of the tapering nest.
