Embodiment is further described the specific embodiment of the present invention below in conjunction with drawings and Examples:

Referring to Fig. 1, the inventive system comprises track guide rail 4, coaster 5 and I directive wheel 2, II directive wheel 9 and III directive wheel 6, wherein I directive wheel 2 and II directive wheel 9 respectively by the bearing sliding bearing on I wheel frame 3 and II wheel frame 8, III directive wheel 6 then is slidingly mounted on the minor axis on base plate 11 right sides of being fixed in coaster 5 on 17 by bearing.I wheel frame 3 is fixedlyed connected by connecting plate 7 with II wheel frame 8, and is weldingly fixed on together on the left surface of base plate 11 of coaster 5, and III directive wheel 6 then is arranged on the minor axis 17 on base plate 11 right sides of coaster 5.The relative position relation of three directive wheels is as follows: the wheel side of I directive wheel 2 and II directive wheel 9 is positioned at same plane perpendicular to track guide rail 4 surfaces, the wheel side of III directive wheel 6 is parallel to track guide rail 4 surfaces, and grooving center line projection on the guide surface 12 in track guide rail 4 of II directive wheel 9 and III directive wheel 6 two-wheeleds is just in time tangent.

Track guide rail 4 is welded by shaped steel, its spigot surface is substantially parallel with car guide rail, it has two

spigot surfaces

12,13, these two

spigot surfaces

12,13 are parallel with car guide rail, coaster 5 is made up of base plate 11 and four coaster wheels 10, each coaster wheels 10 all has wheel shaft vertically disposed two

wheels

14,15 mutually, and these two

wheels

14,15 can slide on two

spigot surfaces

12,13 of track guide rail 4 respectively, to 5 supportings of coaster guide effect.

Fig. 2 shows the position relation of track guide rail 4 and guiding wheels, and Fig. 3 is the partial enlarged drawing of A among Fig. 2.

Trailing cable 1 one ends are fixed in car 16, the other end detours successively and is fixed in hoistway top after the I directive wheel 2, II directive wheel 9, III directive wheel 6, and the part that trailing cable 1 is walked around I directive wheel 2, II directive wheel 9, III directive wheel 6 successively drops in the cable trunking 18 all the time.Find out that by Fig. 2 the projection of III directive wheel 6 should be arranged in cable trunking 18.When lift car 16 moves upward, drive trailing cable 1 motion, lift each

directive wheel

2,9,6, drive coaster 5 and upwards move along track guide rail 4 given tracks; When lift car 16 moved downward, trailing cable 1 is operation downwards simultaneously, and coaster 5 is influenced by self gravitation, in the time of tensioning trailing cable 1, moved downwards along track guide rail 4 given tracks.Because the trailing cable 1 that move up and down with car 16 is by around slip flexibly on three

directive wheels

2,9,6, and all the time by coaster 5 tensionings, and coaster 5 is subjected to the guide effect of track guide rail 4, guaranteed that effectively trailing cable 1 adds normal operation in the circular arc hoistway in inclination hoistway or inclination, avoids the influence of 1 pair of other parts of elevator hoistways of trailing cable.
