  • Moving a heavy overload with an elevator
    Patent number: 11554936
    Abstract: An elevator installation and a method of operating the elevator system for temporary transportation of an overload within the elevator installation includes a car and a counterweight interconnected by one or more suspension ropes engaging a traction sheave that is driven by a motor. The traction between the suspension ropes and the traction sheave is enhanced independently of the counterweight for intended overload operation.
    Type: Grant

  • Selective elevator braking during emergency stop
    Patent number: 9227815
    Abstract: A method for controlling movement of an elevator car during an emergency stop includes the steps of determining the load of the car; determining the travel direction of the car; and monitoring the speed of the car. When the car is determined to be either lightly loaded and travelling downwards, or heavily loaded and travelling upwards, brake torque is applied only when the speed of the car reaches zero, as slowing of the car can be accomplished solely by virtue of the balancing factor of the car's counterweight.

  • SELECTIVE ELEVATOR BRAKING DURING EMERGENCY STOP
    Publication number: 20130105248
    Abstract: A method for controlling movement of an elevator car (20) during an emergency stop (S1) comprising the steps of determining a load of the car (S4;S8;S9;S10), determining a travel direction of the car (S3) and monitoring a speed (V) of the car (S6). When the car is travelling downwards (S3) and is lightly loaded (S8) or when the car is travelling upwards (S3) and is heavily loaded (S10), brake torque is applied (S7) only when the speed (V) of the car reaches zero.

  • Elevator installation with equipment for compensation for the weight difference between the cage runs and the counterweight runs of the support means and method of realizing such compensation
    Publication number: 20070131489
    Abstract: In an elevator installation with an elevator cage, a counterweight and at least one hanging cable with integrated conductors for transmission of energy and/or control signals compensation is provided for the weight difference between the cage runs and the counterweight runs of the support by hanging cables hanging between a fixing point of the elevator installation and the elevator cage or the counterweight, wherein the hanging cable includes an arrangement for increasing its weight per meter.
