Abstract

PURPOSE: To prevent a weight for a tape from dropping off a counterweight for the gondola due to the secular elongation of rope for driving a controller, by providing detecting swtiches which operate in response to the abnormal tension of the rope.
CONSTITUTION: To attach the tape 5 to the gondola 1, a rod 12 fitted with the tape 5 is inserted through a support 11 for the gondola 1 and a spring 13 and a lever 14 are clamped. The switches 16, 17, which are operated by the lever 14, are secured to the support 11. To attach the tape to the counterweight 2, the tape is coupled to the weight 9 extending through a hole of the counterweight 2 and a contact plate 18 is provided on an end of the weight 9. When the rope 3 is securely elongated, the contact plate 18 comes into contact with the weight 2 because the tape 5 is not elongated. At that time, the lever 14 is deflected to operate the switch 17 to supply a dangerousness signal or stop the elevator. When the tape 5 slackens or breaks, the switch 16 is operated.
