r was founded in Germany01/12/1945 and isspecialized in manufacturingand installation of elevators
And Hanz LiftsCompany is the sole agent in the Middle East.
It was thecompany Alois Kasper lead in the invention of the external rotor tractionmachine contrary to the other traction machine used for elevators , here is theadvantages of this system :
Because the external rotor motor was designed without its own bearing it is almost maintenance-free. In addition the worm is rigidly connected to the rotor housing so there is no need for any clutch parts. There is no need for either a motor alignment nor a motor substructure.
The rotor housing also serves as an emergency handwheel and brake disk
The motor retainer is connected to the drive housing.
Depending on the number of switching actuations the built-on fan blower together with the arrangement of the air flow channels produce cooling of the bearing and cooling when the elevator is stationary, and at the same time also cool the drive bearing near the motor, the motor, the handwheel and the braking surface.
The reduction of the motorand worm bearings exclusively to a worm two-point bearing creates avibration-free, smooth ride. The result is a compact design which provides ahigh degree of comfort.
