PURPOSE: To improve riding comfortability by way of preventing sinking and floating of a passenger cage caused by getting-on-and-off of a passenger at the time when an elevator stops by setting a brake device on a ceiling beam and braking rotation of a static pulley fixed on the ceiling beam of an elevator shaft at the time when the passenger cage stops. CONSTITUTION: A passenger cage 1 is elevated up by sequentially suspending a static pulley 4 and a dynamic pulley 5 by way of fixing one end of a rope 3 on the passenger cage 1 and pulling the dynamic pulley 5 by a fluid pressure cylinder 10. In such a fluid pressure elevator, a brake device 30 to brake rotation of the static pulley 4 is set on a ceiling beam 8. Additionally, a means to detect tensile force and strain of the rope 3 is furnished on both ends of the rope 3. Rotation of the static pulley 4 is made impossible by braking the static pulley 4 by the brake device 30 set on the ceiling beam 8 at the time when the passenger cage 1 stops. Consequently, it is possible to eliminate sinking and floating of the passenger cage caused at the time of getting-on-and-off of a passenger. |
