Definitions
- the invention relates on the one hand to a method for erecting an elevator system in a building in its construction phase, in which method a usable lifting height of the elevator system is adapted to an increasing height of the building, and on the other hand to an elevator system suitable for carrying out the method.
- Such an elevator system usually comprises a machine platform that is movable along an elevator shaft and can be temporarily locked therein, with an elevator drive machine, as well as at least one elevator car suspended from the machine platform via suspension means and driven by the elevator drive machine.
- the usable lifting height of the elevator car is adapted from time to time to an increasing height of the building, in that at least the machine platform carrying the elevator car is raised to a higher level with the help of a lifting platform temporarily fixed above the machine platform.
- Such an elevator system or such a method is known from WO2010 / 100319, in which an elevator car and a counterweight are suspended via flexible traction means on a machine platform that can be raised and temporarily fixed in the elevator shaft.
- the traction means are guided over a traction sheave of an elevator drive machine, so that the traction means are driven by the traction sheave and thus the elevator car and the counterweight can be moved up and down in opposite directions in the elevator shaft. From time to time the machine platform is raised to a higher level corresponding to the increasing building height and fixed there in the elevator shaft.
- the elevator system can, on the one hand, transport people and material to the topmost area of the building currently in its construction phase, and, on the other hand, that the users from lower, already developed floors, as well as their furniture, for example, can be transported through the elevator system .
- a lifting platform that can also be raised and temporarily fixed in the elevator shaft is installed above the machine platform.
- a group of pulleys is attached to both the lifting platform and the machine platform, with the pulley group between the Lifting platform and the pulley group of the machine platform a multiple reeved lifting rope is arranged so that the machine platform can be raised with the help of two cable pulling devices mounted on the machine platform.
- the lifting platform Before each lifting of the machine platform, the lifting platform must be brought to a higher level in the elevator shaft. This is done with the help of a hoist that is attached to a further supporting structure that can be displaced and fixed in the elevator shaft and that can raise the lifting platform using a hoisting rope.
- the risk of the machine platform falling is usually reduced by equipping it with safety brakes that act on guide rails of the elevator car on which the machine platform is also guided. If a maximum permitted downward speed is exceeded in any situation, the safety brakes are activated and the machine platform is stopped by the braking effect between the guide rails and the safety brakes.
- the present invention is based on the object of creating a method and an elevator system of the type described above suitable for carrying out the method, in which the risk of the lifting platform falling and thus also the risk of accidents for the assembly personnel is minimized when the lifting platform is raised.
- the solution to the problem consists on the one hand in a method for setting up an elevator system in an elevator shaft of a building which is in its construction phase, in which method a usable lifting height of the elevator system is adapted to an increasing height of the building, with a temporarily liftable and temporary lift shaft in the elevator shaft lockable machine platform is installed on which an elevator drive machine with a traction sheave is arranged, an elevator car and a counterweight being suspended from the machine platform via suspension means, the suspension means being guided at least over the traction sheave of the elevator drive machine, so that the elevator car and the counterweight through the traction sheave via the support means along guide rails in the elevator shaft up and down in opposite directions to one another can be moved, with a liftable and temporarily lockable lifting platform installed in the elevator shaft above the machine platform, with which the machine platform - usually with the elevator car coupled to it - is raised when the usable lifting height of the elevator car is to be adapted to a current height of the elevator shaft, with before the machine platform is raised, the lifting platform is
