Abstract

The invention provides an elevator capable of reducing the deflection load of the elevator car by the sternfast without adding a special device. The elevator comprises a lift passage, a pair of guides disposed in the lift passage, a elevator car suspended by the main cable and up and down along the guides, a lower frame of the elevator car, a sternfast of which one end is connected with the suspending part fixed on the lower frame of the elevator car and the other end is connected with the middle part of the lift passage, wherein a side end of the elevator car of the sternfast is suspended near the suspending center in back-front direction of the elevator car, and at the same time, the sternfast is suspended slantways to form an angle between the line connecting the side end of the lift passage of the sternfast with the side end of the elevator car and the line of the pair of guides.

Description

technical field [0001] The invention relates to an elevator device in which a tail cable is suspended at the lower part of an elevator car. Background technique [0002] refer to Figure 5 to Figure 7 A suspension structure of a tail cable in general elevator equipment will be described. Figure 5 It is a cross-sectional view of the hoistway illustrating the approximate suspension structure of the elevator tail cable in the prior art, Figure 6 yes Figure 5 The schematic diagram of the suspension structure at the bottom of the elevator car, Figure 7 yes Figure 5 The top view of the elevator tail cable suspension structure. [0003] Such as Figure 5 As shown, the elevator car 7 suspended by the main rope 6 and having the guide device 8 at the upper and lower parts travels vertically in the hoistway 1 under the guidance of the guide rail 5 arranged in the hoistway 1 . In a high-travel elevator, auxiliary ropes 12 are suspended from the bottom of the elevator car 7 an...
