Hydraulic Elevator

A hydraulic elevator is a type of elevator that uses a hydraulic system to lift and lower the cab. It is commonly used in low- to mid-rise buildings (up to 6–7 floors) due to its cost-effectiveness, durability, and smooth operation. Unlike traction elevators, hydraulic elevators do not require overhead machine rooms, making them a practical solution for buildings with space constraints

How a Hydraulic Elevator Works

A hydraulic elevator operates using pressurized hydraulic fluid (usually oil) to power a piston (ram), which moves the elevator cab up and down. The system consists of:

Hydraulic Pump – Pressurizes hydraulic oil and pushes it into a cylinder.
Cylinder & Piston – The pressurized oil moves the piston, lifting the elevator cab.
Control Valve – Regulates the flow of oil to ensure smooth movement.
Tank (Reservoir) – Stores the hydraulic oil when the elevator is not in motion.
