Letter TControl panel with buttons for transferring commands to the controller. The stop is selected via the inside panel, the outside panel is used to bring the elevator car. Various additional functions such as door-close buttons, call coding or TFT displays offer additional convenience. See also TFT screen.

Calculatively and practically verifiable size for optimal power transmission between the suspension element (e.g. steel wire rope) and the traction sheave in rope elevators. The driving ability depends on the pretensioning force, wrap angle and friction value.

Here you can find more detailed explanations on the subject of the engine ...Drive too. There are different types of elevator drives that have to be checked depending on the elevator's performance in order to find an economical and optimal solution for the elevator system. 1. Hydraulic power unit With the hydraulic drive, the cabin is moved upwards by one or more pistons when the oil pressure is increased. The pistons are also anchored in the bottom of the shaft. And the oil from the motor and pump is pumped into the pistons by means of a hydraulic line. No energy is required when going down. Because the oil is pushed back again due to the force of gravity in the cabin, checked and controlled by appropriate valves. If the pistons are directly connected to the cabin, it is a direct hydraulic drive. The indirect hydraulic drive transmits the power to the cabin through pulleys and ropes. A hydraulic power unit is not suitable for high delivery heights. Advantages: - very economical at lower delivery heights; - Structural advantage, the engine can also be housed remotely.
Next point:2. Traction sheave drive with gearbox Electric drive, consisting of motor, traction sheave, suspension element, counterweight, with / without frequency control. a) with worm gear: translation and power transmission between motor and traction sheave through a worm gear. The gear consists of the worm wheel, a special form of helical gear, and the spindle. b) with helical worm gear or double worm gear: Also worm gear, with an additional upstream spur gear or a second worm gear; results in a significantly higher degree of efficiency than the pure worm gear and is particularly smooth and quiet. c) with planetary gear: translation and power transmission between motor and traction sheave through a planetary gear. Also called epicyclic gears. Several cogwheels revolve around a central cogwheel, rotating on axes, which is reminiscent of our solar system and led to this name. d) V-belt drives were introduced in the 1960s, but are no longer installed today due to the large amount of space required and the relatively rapid wear of the V-belts. In general, the following applies to gear types a to c: Suitable for travel speeds up to 2m / s Advantages: - high driving comfort with low energy consumption - entry with millimeter precision and automatic readjustment of level differences when loading and unloading
Finally ...3. Traction sheave engine without gearbox The rotor of the electric motor is directly connected to the traction sheave, which is why it is also called a gearless drive. This drive is suitable for high speeds of up to 12.5 m / s and is particularly quiet. This engine also offers high ride comfort and optimal stopping accuracy and is also characterized by low energy consumption. Traction sheave drives are generally available with or without frequency control. The modern processor control with a modern frequency control offers many advantages: - Jerk-free and stepless regulation of driving speed and stopping process. - Optimization of the driving comfort and the approach accuracy - maximizes the achievable driving speed, minimizes the waiting time. See also pole changing. Cabin doors are opened and closed with a separate electric motor and a control. Thus, the control regulates the opening speed and travel curve of the door according to the presetting. In addition, the shaft end doors are operated together with the car door without their own drive.

Letter UIf the nominal load is exceeded by more than 10% and at least by 75 kg, this is referred to as overload. Furthermore, the elevator does not leave the stop and indicates the situation acoustically or optically. See also load measurement.
