Abstract (en)
[origin: EP1447370A1] A support member (10) for supporting a hoisting machine (9) disposed at a position close to the top within a hoistway (1) is supported at an upper end section of counterweight rails (6) which stand upright within the hoistway (1) and guide ascending and descending operation of a counterweight (8). In connection with such a construction, a coupling member (17) is provided between rail brackets (4)-which are spaced apart from each other in the vertical direction and fasten car rails (3) to fixing members (5) of the hoistway (1)-thereby coupling the counterweight rail (6) to the car rail (3). <??>As a result, the displacement developing in the counterweight rail (6) in the direction orthogonal to the axis is transmitted to and supported by the car rail (3) by means of the coupling member (17). Consequently, occurrence of buckling in the counterweight rail (6) is prevented, thereby making the strength of the counterweight rail (6) close to that required to carry out a function of guiding the counterweight (8). The counterweight rail (6) can be reduced in size to a rail of standard size, thereby curtailing costs for constructing the elevator system. <IMAGE>
