A rope storage unit for storing an elevator rope during transportation and/or installation of the elevator rope includes a rope reel, formed by a rope wound in a spiral form and having a central axis; and a support frame provided with an inner space inside which the rope reel is positioned supported by the support frame such that it can in use be rotated in the inner space for unwinding the rope. The rope is a rod having a straight form when in rest state and elastically bendable away from the straight form, the rope being under substantial bending tension in the spiral form, and wherein the support frame comprises three or more rotatable support rollers delimiting the inner space and surrounding radially the rope reel. A method for installing an elevator rope implements the rope storage unit.

The object of the invention is a method for installing an elevator in the construction phase of a building. The elevator comprises an elevator car adapted to move reciprocally in an elevator hoistway in the construction phase and a compensating weight, which is connected via a suspension beam to support the elevator car by means of at least one suspension member and also by means of diverting pulleys. The elevator has a temporary hoisting machine provided with a traction sheave, the hoisting machine being kept in its position for the whole duration of the construction phase of the building, and a traction member, such as a belt, rope or chain, which is adapted to transmit the rotational movement of the traction sheave into movement of the elevator car and of the compensating weight. During the construction time, the supporting and the moving of the elevator car are separated from each other. When taking the elevator into normal operation when the building is at its final height, the construction-time hoisting machine with its traction sheave and traction member is removed, and the new hoisting machine plus traction sheave and hoisting roping is installed into position.

An elevator has a safety controller to which several safety switch arrangements are connected. The safety controller is configured to cause the stop of the elevator motor and the activation of the motor brakes. A comparator is provided in the safety controller for the determination of the status of the safety chain. The comparator is connected with a memory for storing at least one resistor reference value, which comparator is configured to output a safety chain status signal in dependence of comparison of a measured resistance value with the resistor reference value. Each of said safety switch arrangements includes at least one first resistor and a safety switch which are connected in series. The value of the first resistor is different in at least some safety switch arrangements, preferably in all safety switch arrangements. Each safety switch arrangement includes at least a second resistor connected in parallel with the safety switch, which second resistor has a higher value than the first resistor. The detection of a short circuit as well as of the opening of a safety switch arrangement are allowed.

A material transport and installation arrangement comprising a first working platform system in an elevator shaft for reaching a first installation height; and a first material hoisting system for moving elevator components vertically in the elevator shaft is disclosed. The arrangement is characterized in that it comprises a second working platform system in the elevator shaft for reaching a second installation height, the second working platform system comprising a second platform hoist, second platform roping and a vertically moveable second working platform, the second working platform being below the first working platform; and a second material hoisting system for moving elevator components vertically in the elevator shaft, the second material hoisting system comprising a second material hoist, second material roping and a second material holder. Further, a method for parallel transport and installation of elevator components is disclosed.

Arrangement and a method for parallel transport and installation of elevator components

A method includes plumbing an elevator shaft, installing a lowermost first section of guide rail elements manually to walls of the shaft, arranging an upwards and downwards in the shaft with a first hoist movable lifting frame, arranging an upwards and downwards in the shaft with a second hoist movable installation platform provided with a guide apparatus, an installation apparatus and an alignment tool, drilling holes and fastening support brackets to the walls of the shaft with the installation apparatus, lifting guide rail elements with a third hoist from the lifting frame and guiding said guide rail elements into position with the guide apparatus, joining consecutive guide rail elements with the installation apparatus, and aligning opposite guide rail elements with the alignment tool and locking the support brackets with the installation apparatus.

Method and an arrangement for installing elevator guide rails

The apparatus includes a positioning unit and an alignment unit. The positioning unit extends across the elevator shaft in a second direction and comprises at each end a first attachment mechanism movable in the second direction for supporting the positioning unit on opposite wall structures in the elevator shaft. The alignment unit extends across the elevator shaft in the second direction and is supported with support parts on each end portion of the positioning unit. Each end portion of the alignment unit is individually movable in relation to the positioning unit in a third direction perpendicular to the second direction. The alignment unit includes further at each end a second attachment mechanism movable in the second direction for supporting the alignment unit on opposite guide rails in the shaft. The second attachment mechanism includes a gripper for gripping on the guide rail.

Apparatus and method for aligning guide rails in an elevator shaft

A guide rail installation arrangement and a method for installing guide rails are disclosed. The guide rail installation arrangement for installing guide rails in an elevator shaft includes at least one vertically moveable working platform within the elevator shaft for reaching the installation height and a material hoist for moving guide rail sections for installing the guide rail sections. The guide rail installation arrangement further includes a transport frame for transporting guide rail sections vertically within the elevator shaft and a frame hoist that is attachable to the transport frame for vertically moving the transport frame and for optionally moving the guide rail sections for loading the guide rail sections into the transport frame.

In a method for reeving an elevator, a hoisting element of a hoisting device is fixed to a first lifting point, and the hoisting element of the hoisting device is fixed to a second lifting point of the hoisting rope. The hoisting rope is lifted in the elevator hoistway with the hoisting device until the first lifting point and the second lifting point are at the top part of the elevator hoistway. The first end of the hoisting rope is guided to a first fixing point, and the second end of the hoisting rope is guided to a second fixing point. The first end is fixed to a first fixing point and the second end is fixed to the second fixing point.
