Elevator device

An elevator device, comprising:

• a car;
• a counterweight;
• a main rope configured to support the car and the counterweight;
• a hoisting machine to be driven with the main rope wound therearound;
• car rails configured to guide the car;
• a car brake device configured to apply a load to the car rails to brake the car;
• a hoisting-machine controller configured to control the hoisting machine;
• a car brake controller configured to control the car brake device;
• and
• a vibration detection device configured to detect vibration of the car or vibration of a construction for accommodating the elevator device therein,
• wherein, when the car brake controller detects the vibration of a tension of the main rope, the car brake controller controls the car brake device to generate the braking force,
• wherein, under a state in which the hoisting-machine controller controls drive of the hoisting machine and the car brake controller controls the car brake device to generate a braking force, the control of the drive of the hoisting machine is continued,
• wherein, the car brake controller changes the braking force to be generated by the car brake device in accordance with a signal indicative of the vibration detected by the vibration detection device,
• wherein, the car brake controller controls the car brake device to generate the braking force exerted in a direction in which the car is lowered at a timing of decreasing the tension of the main rope, or the braking force exerted in a direction in which the car rises at a timing of increasing the tension of the main rope.
