Abstract
Elevator systems are described. The elevator systems include an elevator car movable along guide rails within an elevator shaft. The elevator car has a car frame with a platform, a ceiling, and car structural members. A distance between the platform and the ceiling is defined as a car height HC. An overspeed safety system is provided and includes first and second safety brakes and first and second electromechanical actuators positioned within the car structural members within the car height HC. The safety brakes are operable to engage with the guide rails to stop movement of the elevator car.
Claims20
An elevator system comprising:
- an elevator car movable along a first guide rail and a second guide rail within an elevator shaft, the elevator car having a car frame comprising a platform, a ceiling, a first car structural member, and a second car structural member, wherein a distance between the platform and the ceiling is defined as a car height HC;
- and
- an overspeed safety system comprising:
- a first safety brake and a first electromechanical actuator operably connected thereto, wherein the first safety brake and the first electromechanical actuator are positioned within the first car structural member within the car height HC, and wherein the first safety brake is operable to engage with the first guide rail to stop movement of the elevator car;
- and
- a second safety brake and a second electromechanical actuator operably connected thereto, wherein the second safety brake and the second electromechanical actuator are positioned within the second car structural member within the car height HC, and wherein the second safety brake is simultaneously operable with the first safety brake to engage with the second guide rail to stop movement of the elevator car.
