Unlike the hydraulic elevator, which uses a piston to function, a traction application operates with a rope (also called hoists) or belt system.
The hoists run over a wheel, creating a pulley system with counterweights. The name "traction" is derived from the friction that results from the hoist ropes and drive sheave working together.
These ropes are made from twisted fibers, often steel, to create a durable cord or cable which links the elevator cab sling to the counterweight and over the drive sheave.
The very first passenger elevator system, which was revealed to the world in 1857, relied on ropes similar to those we have today. This method is still considered a trustworthy option, especially for high-rise buildings and skyscrapers which require a sturdier system to travel incredible heights.
