Embodiment Construction

[0028] The schematic diagram of the traction sheave elevator of the present invention is shown in Fig. 1 . The car 1 and the counterweight 2 are suspended on the hoisting rope 3 of the elevator. The hoisting ropes 3 preferably support the car 1 substantially centrally or symmetrically to a vertical line passing through the center of gravity of the elevator car 1 . Likewise, the suspension of the counterweight 2 is also preferably substantially central or symmetrical about a vertical line passing through the center of gravity of the counterweight. In FIG. 1 , the car 1 is supported by the hoisting rope 3 through the diverting pulleys 4 and 5 with rope grooves, and the counterweight 2 is supported by the diverting pulley 9 with grooves. The diverting pulleys 4, 5 preferably revolve substantially in the same plane. The hoisting cable 3 usually consists of several strands arranged side by side, generally at least 3 strands. An elevator drive 6, with a traction sheave 7 engaging...

Abstract

The traction sheave elevator comprises an elevator car (1) moving along elevator guide rails (10), a counterweight (2) moving along counterweight guide rails (11), a set of hoisting ropes (3) on which the elevator car and the counterweight are suspended, and a drive machine unit (6) comprising a traction sheave (7) driven by the drive machine and engaging the hoisting ropes (3). The drive machine unit (6) of the elevator is placed in the top part of the elevator shaft (15) and in the horizontal cross-section of the shaft between the vertical projection of the cabin and the shaft wall, whereby the drive machine unit is fixed to a wall or the ceiling of the elevator shaft.

Description

[0001] This application is a divisional application of an invention application whose filing date is 940628, application number is 94106597.9, and the title is called traction sheave elevator. technical field [0002] The invention relates to a traction sheave elevator and a driving device for the elevator. Background technique [0003] One of the goals in the development of elevators is the efficient and economical use of building space. In conventional elevators driven by traction sheaves, the elevator machine room or the elevator space reserved for the drive machinery accounts for a considerable portion of the building space required by the elevator. The issue is not just the amount of building space required to drive the machinery, but its location in the building. There are many solutions for setting up the computer room, but usually these greatly limit the building design, at least in terms of space utilization or appearance. For example, setting the computer room sp...
