Method for constructing elevator and elevator

A method for constructing an elevator, comprising

• providing an elevator car;
• providing a plurality of prefabricated hoistway modules to be piled on top of each other, each separate prefabricated hoistway module of the plurality of prefabricated hoistway modules bordering a separate hoistway space into which an entire elevator car or at least an upper or lower end thereof can be fitted to move, such that the plurality of prefabricated hoistway modules border separate, respective hoistway spaces into which the entire elevator car or at least the upper or lower end thereof can be fitted to move;
• piling the plurality of prefabricated hoistway modules on top of each other to form a piled plurality of prefabricated hoistway modules, such that the separate, respective hoistway spaces of the plurality of prefabricated hoistway modules are vertically aligned with each other to form 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 space,
• wherein the plurality of prefabricated hoistway modules includes a prefabricated top module, the prefabricated top module being an uppermost prefabricated hoistway module in the piled plurality of prefabricated hoistway modules, and
• wherein the prefabricated top module includes
• a machinery configured to drive a hoisting roping, and
• one or more car guide rail sections,
• wherein the machinery configured to drive the hoisting roping is mounted on a single car guide rail section of the one or more car guide rail sections of the prefabricated top module, such that the single car guide rail section is configured to carry both a complete weight of the machinery and a load exerted by the hoisting roping passing around a drive wheel of the machinery,
• wherein the single car guide rail section and a separate car guide rail section of the one or more car guide rail sections are fixed to different horizontal beams such that the single car guide rail section and the separate car guide rail section are fixed to the horizontal beams configured to be on opposite sides of the elevator car in the hoistway space.
