The invention relates to a method for constructing an elevator, comprising providing an elevator car; providing plurality of prefabricated hoistway modules to be piled on top of each other, each hoistway module bordering a hoistway space into which the whole elevator car or at least an upper or lower end thereof can be fitted to move; and piling said plurality of prefabricated modules on top of each other, such that the hoistway spaces of the prefabricated modules are vertically aligned forming a continuous vertically elongated hoistway where the elevator car can be fitted to move; and arranging the elevator car to be vertically movable in the hoistway. The invention also relates to an elevator obtained with the method.

A drive system for an elevator installation includes a drive and a drive suspension for fastening the drive to a support element of the elevator installation. The drive suspension has a rotary joint for tiltably mounting the drive on the support element and an adjustment device for setting a tilt of the drive about the rotary joint.

An elevator arrangement, includes an elevator hoistway, an elevator car, which is arranged to travel in the elevator hoistway, a counterweight, a movable supporting platform above the elevator car, suspension roping, which is connected to the elevator car and to the counterweight, and supports them while suspended from the supporting platform, and a hoisting machine, which includes a device configured to move the roping. The elevator arrangement also includes a hoisting machine and traction roping that are separate from the supporting platform, which hoisting machine is in power transmission connection via the traction roping with the elevator car and with the counterweight.

A radial flux permanent magnet elevator motor includes a motor frame forming the stator frame having fixing points to be fixed to an elevator guide rail, which frame has a back wall facing and/or abutting with the guide rail, which motor frame includes an axially extending flange protruding away from the back wall in the direction of the rotor, and which motor frame includes at least one axially extending first wall section in a defined radial distance from the axis of the motor frame, which first wall section is configured to support a stator winding of the motor. The rotor includes a central hub protruding into the flange of the motor frame and is rotatively supported within the flange via bearings, which rotor includes a traction sheave in a first radial distance from the motor axis and a ring-like support wall in a second radial distance from the motor axis for supporting permanent magnets, which second distance is larger than the first distance, and whereby the stator winding and the permanent magnets form a radial air gap.

A flexible elevator machine frame is provided. The flexible elevator machine frame includes a first end supportive of a motor, a second end supportive of a brake, a central portion and an adapter assembly. The central portion is interposable between the first and second ends and is configured to accommodate a base traction assembly between the motor and the brake. The central portion includes first and second end sides which are associated with the first and second ends, respectively, and which are configured to be fastened together. The adapter assembly is configured to be fastened between the first and second end sides to accommodate the base and an additional traction assembly between the motor and the brake.

An elevator shaft element, an elevator arrangement and a method of a construction time use elevator. The elevator shaft element comprises a frame module arranged for receiving an elevator car therein. The frame module is constructed from a transport and/or storage unit, comprising side walls, a bottom wall and a roof wall. The unit is arrangeable vertically such that said side walls, bottom wall and upper wall of the unit define an inner space of the elevator shaft. The side wall, the bottom wall or the upper wall of the transport and/or storage unit is opened at a length more than a floor height of a building for providing an opening for one or more landing doors, the opening having a first side-edge and a second side-edge parallel to longitudinal direction of the transport and/or storage unit. The elevator shaft element further comprises at least one stiffening beam arranged to be fixed to the opening and extending from the first side-edge to the second side-edge.

An elevator traction machine installation apparatus includes a lifting mechanism having a base portion and a load-bearing portion adapted to place an elevator traction machine, the base and load-bearing portions are connected and can rise and lower relative to each other in a longitudinal direction of an elevator hoistway; and a support mechanism configured to be detachably connected with the lifting mechanism and a base for installation of a machine-room-less elevator traction machine in the elevator hoistway to support the lifting mechanism and the elevator traction machine, and having at least two positions at which the base portion is secured, a first position is lower than a second position in the longitudinal direction, and the load-bearing portion is lifted relative to the base portion after the base portion is secured at the first position, and continues to be lifted relative to the base portion.

An elevator system is provided including a hoistway having a plurality of landings. An elevator car is configured to move within the hoistway between the plurality of landings. A plurality of guide rails guide movement of the elevator car and a counterweight within the hoistway. Each guide rail includes a base and a blade. A machine assembly is mounted within the hoistway and includes a traction sheave rotatable about an axis. The traction sheave is configured to drive movement of the elevator car between the plurality of landings. At least one of the plurality of guide rails is arranged in an overlapping configuration with the machine assembly such that a plane defined by the base of the guide rail is parallel to the axis and intersects a portion of the traction sheave.
