A drive system for an elevator installation includes a drive and a drive suspension for fastening the drive to a support element of the elevator installation. The drive suspension includes a rotary joint for tiltably mounting the drive on the support element and an adjustment device for setting a tilt of the drive about the rotary joint. The support element can be a guide rail wherein the drive system is arranged in an upper end region of the elevator installation.

Drive system for an elevator installation, elevator installation, and method for installing a drive on a support element of an elevator installation

A method and a mechanism for releasing a hydraulically actuated elevator brake system wherein the brake release mechanism includes a rotary pump, a crank handle to manually turn the rotary pump, a fluid supply port, a fluid return port, an output port for connection to a cylinder of the brake system, a rapid exhaust valve having an inlet port connected via the rotary pump to the fluid supply port, a cylinder port selectively connectable to the output port, and an exhaust port connected to the fluid return port. By turning the rotary pump, for example with the crank handle, a continuous flow of pressurized hydraulic fluid is delivered through the rapid exhaust valve and onto the brake cylinder, thereby releasing the hydraulic brake system.

Method and mechanism for releasing hydraulic elevator brakes

A method for operating an elevator having a car driven by a motor and at least one brake to stop the car, the method including closing a brake, increasing a torque of the motor until the car moves, and registering a value indicative of the motor torque at which the car moves.
