Hydraulic elevator
Hydraulic elevators are divided into two groups with shaft and without shaft. The hydraulic elevator with shaft has a pulley rope at the bottom of the elevator shaft, which receives the collected piston when the elevator descends.
But the hydraulic elevator without a well has a piston on both sides of the cabin, which is divided into three categories: rope hydraulic elevator, telescopic hydraulic elevator and non-telescopic hydraulic elevator.

Tensor elevator
🔸 Traction elevators are the oldest type of elevators. In summary, this kind of elevators consists of the cabin, a weight connected to the two ends of the towing wire that moves on a large pulley called a sheave. The weight and the elevator cabin tend to achieve balance. Finally, it causes that little energy is needed to move the elevator cabin. When the elevator car moves up, the weight moves down and also when the elevator car moves down, the weight moves up.
