PROBLEM TO BE SOLVED: To provide an elevator having a structurally simple 4:1 cable guidance. SOLUTION: A drive unit 5 and a first deflecting roller 8 are disposed on a carrier 21 supported by one end of a first cage guide rail 15 combined with a first counterweight guide rail 19 and the other end of a second counterweight guide rail 20. These guide rails are connected by a yoke to an elevator shaft wall, so that vertical rail force is transmitted to an elevator shaft pit. A drive bracket 23 disposed on the carrier supports the drive unit 5 and a drive pulley 3. A roller bracket 24 disposed on the carrier supports the first deflecting roller 8. A first cable fixing point 6 and a second cable fixing point 13 are disposed on the carrier. A second deflecting roller is supported on a second cage guide rail. COPYRIGHT: (C)2005,JPO&NCIPI |
