<p>PURPOSE:To smoothly raise and lower a cage chamber, preventing the device from being damaged by the fall of a contaminated article on a guide rail by allowing a main rope guide device and a cage frame supporting a cage chamber to be adsorbed and released by an electromagnet, in the bendable part of an aslantly traveling elevator. CONSTITUTION:When a cage chamber 4 is lowered from the upper part of a supporting board 7 which is fixedly installed onto the bent part 2a of an elevator passage 1, an electromagnet arranged on a cage frame 3 is excited, and a main rope guide device 6 is lowered, attracted to a guide rail 2 side. When the main rope guide device 6 lowers to the position of the supporting board 7, the excitation of the electromagnet is released, and the main rope guide device 6 is placed onto the supporting board 7, and stops at that position, and the cage frame 3 is released to lower the cage chamber 4. When the cage frame 3 is raised from under the supporting board 7, if the cage frame 3 is approached to the supporting board 7, the electromagnet is excited, and the cage frame 3 and the main rope guide device 6 are joined again, and the cage chamber 4 can be raised, suppressing the dangling of a main rope 5 in the vertical direction.</p> |
