In a preferred embodiment, the method comprises using the car or at least parts of the car as the working platform to be guided on the car guide rails.
In a preferred embodiment, the method comprises using the installation platform as the working platform.
The method and the arrangement described are preferred for midrise buildings. In such a sectional installation method and arrangement, the elevator is installed in phases for construction time use CTU. The installation can start when the building has reached an agreed height.
The construction of the building can continue above a CTU elevator which is operating in the bottom section or a below section of the hoistway. Simultaneously the elevator installation in the same hoistway can be continued above the operating CTU elevator, and when the time is right, a conversion into the CTU elevator with extended travel or the final elevator can be made.
The elevator installation is possible when the building is raising up, already before a hoistway ceiling is closed and corresponding lifting or hoisting points for elevator installation are in place in the ceiling.
The elevator in the bottom section and potential intermediate sections can be used during construction while the building is still under construction, at the stage when the building starts its busiest phase of work, i.e. the floors are started to be finished and furnished, allowing materials and persons to be transported effectively inside the building, protected from the weather, and not having to pass as much on the stairs, resulting in a significant reduction in the potential number of accidents at work.
During the construction of the building, site logistics can be improved for the transport of people and goods, and based on better site logistics shorter construction time can be achieved. This means that the finalized elevator can be delivered to the customer earlier.
Using an installation platform and a protection deck enables earlier availability of the continued installation of elevators.
When the building is raising, protection decks can be installed which provide lifting for hoisting points for a hoist device such as a man riding hoist and an overspeed governor. The use of protection decks also protects the installers inside the hoistway. The use of a protection deck also provides an installation base at the bottom areas of the intermediate and top sections.
Once the bottom section is installed, the elevator can be put into CTU operation, and since the guide rails can be installed and moved through the protection deck, the installation above the protection deck can be continued for a potential intermediate section or an uppermost section, also called a top section.
The elevator in the bottom section and potential intermediate sections can be used during construction while simultaneously the elevator installation can continue in the same hoistway. When the CTU elevator is operated in the bottom section or the intermediate sections, the installation can continue with the installation platform in the section above the CTU elevator.
Thus, a further protection deck for supporting the installation platform can be installed in an intermediate section above the previous finished bottom section or a previous finished intermediate section. Once the intermediate section is installed and the installation platform is removed from the hoistway, the extension of the elevators travel can begin, with the suspension ropes being replaced or extended to allow for a longer travel and the motor and other components being moved to a temporary headroom to a top of the intermediate section. This will allow a longer travel for the elevator in CTU. The jump relating to the intermediate section can be done as many times as the customer needs.
Once the top section is installed and the installation platform is removed from the hoistway, the final extension of the elevators travel can begin, with the suspension ropes being replaced or extended to allow for a longer travel and the motor and other components being moved to a headroom at the top of the hoistway in case of a machine-room-less elevator or to a machine room above the hoistway in case of a machine room elevator. This will allow a longer travel for the elevator in CTU.
The invention will in the following be described in greater detail by means of preferred embodiments with reference to the attached drawings, in which:
A weather deck 101 and a temporary working deck 102 may be installed in the elevator hoistway 1 preferably by the builder. The weather deck 101 may be an inclined waterproof deck which seals the hoistway 1 to keep it clean and dry.

The suspension roping 31 is arranged to suspend the car 10 and the counterweight 13 for bottom section of the elevator. The suspension ropes 31 are preferably wound on cable drums (not shown in Figures) from bottom section of the elevator so that suitable length of the suspension ropes 31 may be unwound from each cable drum during the installation of the construction elevator. The weight of the elevator hoisting machine 30, as well as the load exerted by the suspension roping 31 passing around a drive wheel of the elevator hoisting machine 30, is carried by the guide rail section 8, 9, and transmittable by the guide rail section to the guide rail sections below it at least partly so that the complete weight of the of the elevator hoisting machine 30, as well as the load exerted by the suspension roping 31 passing around said drive wheel. The load exerted by the suspension roping 31 passing around said drive wheel is formed partially by weight of the suspension roping 31 and partially by the elevator units, such as the car 10 and the counterweight 13 suspended by the suspension roping 31.
