摘要： PURPOSE: To prevent the entry of dust and gasses into an elevating passage by a method wherein in the case of the elevator to be installed at a place like a cement factory where dust and explosive gasses generate, fresh air is supplied into the elevating passage by a blower and the pressure in the elevating passage is kept at a predetermined value.
CONSTITUTION: An air pressure detector 16 and a gas detector 17 are provided at the lower part of the elevating passage 3 for an elevator and a rubber packing is used on an entrance and exit door 15 to thereby seal the elevating passage 3. Then air is supplied into the elevating passage 3 by a blower 18 and the pressure in the elevating passage is kept at a predetermined value on the base of the set value of the air pressure detector 16. When the air pressure detector 16 operates, the supply of air is stopped. Further, when the existence of any explosive gas is detected by the gas detector 17, a safety circuit is operated to stop the elevator for safety. Accordingly, it is possible to prevent the entry of dust and explosive gasses into the elevating passage.

摘要： 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.
