Embodiment Construction

[0021] 1 and 2, the traction sheave elevator without machine room according to the present invention comprises an elevator car 1 driven by hoisting cables, which are generally indicated by reference numeral 2, according to the installation These hoisting cables can be of different sizes and different configurations as desired.

[0022] Counterweights sliding along guide rails 4 are connected to the elevator car 1 by cables 2 .

[0023] The elevator car 1 shown in FIGS. 1 and 2 moves within the elevator shaft 5 along guide rails 6 which face each other for a preferred center-of-gravity car support.

[0024] The hoisting cables support the elevator car, preferably in such a way that the resultant suspension force passes near the plan projection of the car's center of gravity, similarly the suspension of the counterweight 3 is arranged to support it, preferably near its center of gravity It is supported near the plane projection of .

[0025] To this end, the lower pulleys 7 an...

Abstract

The present invention is about a traction sheave elevator, without the machine room, comprising an elevator car that runs on guide rails placed in the shaft and connected to at least one hoisting rope un-coiling on a diverting pulley driven by a traction sheave. The invention's characteristic consists in comprising a space, outside the elevator shaft, which houses, at least partially, the traction sheave and is equipped with an opening near a floor's door for the access to the drive machine and to the traction sheave, from outside the shaft. The invention also provides for arranging the two diverting pulleys on the counterweight and on the elevator car in a way that one or the other can be tilted with respect to the vertical or arranging them on the same axis and on the same body of the pulley with the grooves of the alternating hoisting ropes.

Description

technical field [0001] The invention relates to a traction sheave elevator without a machine room. Background technique [0002] As is known, in the past, due to these standard adjustment construction procedures, the installation of elevators and similar installations had to provide a suitable space, called a machine room, in which the lifting device and its corresponding drive and control equipment were placed, so Technical space needs to be arranged for such equipment, which increases costs. [0003] In recent years, with changes in elevator construction and installation rules, different solutions have been adopted which do not require having a specific room to accommodate this actuating device, since the traction machine is placed directly inside the elevator shaft, or in any case, Can be located on a ground smaller than the shaft wall size, while the actuation and control equipment can be located in a room, the room is located relative to the floor served by the elevato...
