Traction elevators utilize cables as their primary lifting mechanism, which is a key aspect of their design and operation. In these systems, steel cables are looped over a sheave (a type of wheel) and connected to a counterweight. As the motor drives the sheave, it either lifts or lowers the elevator car by adjusting the tension in the cables. This mechanism allows for smooth and efficient movement, especially in taller buildings where the elevator needs to cover significant vertical distances.

Traction elevators can manage heavier loads and operate at higher speeds compared to some other systems, thanks in part to the mechanical advantage provided by the counterweight. This balance reduces the energy consumed by the motor since it compensates for a portion of the weight of the car and its passengers.

In contrast, hydraulic elevators use a fluid-driven piston system, pneumatic elevators rely on air pressure, and crane lifts are not designed for passenger transport in buildings but are meant for material handling. Understanding these distinctions is crucial for recognizing the appropriate applications for each elevator type in various settings.
