Types of hydraulic passenger lifts

A hydraulic passenger lift is a type of elevator commonly used in buildings to transport people between different floors. It uses hydraulic power to lift and lower the elevator car. Here are some key aspects and components of hydraulic passenger lifts:

• Hydraulic System: The hydraulic system is responsible for lifting and lowering the elevator car. It consists of a hydraulic pump, a hydraulic fluid reservoir, and a set of hydraulic cylinders. The pump draws hydraulic fluid from the reservoir and creates pressure, which is sent to the cylinders. The pressurized fluid pushes the cylinder piston, lifting the elevator car. The fluid control valves regulate the flow of hydraulic fluid to lower the car smoothly and control its speed.

• Cylinders and Pistons: The hydraulic cylinders are metal tubes that house the pistons. They are usually mounted vertically in a shaft next to the elevator car. As the hydraulic fluid fills the cylinder, the piston moves, lifting the elevator car attached to the piston. The movement of the piston within the cylinder allows the elevator car to go up and down.

• Control Valves: The control valves regulate the flow of hydraulic fluid in the system. They control the speed and smoothness of the elevator's movement. The valves ensure the fluid flows to lift the car or descend it gradually, providing precise control over its motion.

• Power Unit: The hydraulic lift power unit consists of a pump, electric motor, and hydraulic fluid reservoir. The electric motor drives the pump to create hydraulic pressure. The power unit is the heart of the hydraulic system, providing the necessary force to lift the elevator car.

• Valve Group: The valve group controls the direction and speed of the hydraulic fluid flow. It consists of solenoid valves and flow control valves. The valve group allows the system to lift the car and lower it smoothly, controlling the motion of the elevator.

• Cabin and Doors: The elevator cabin is where passengers enter and exit. It is equipped with buttons, safety features, and control panels. The cabin can accommodate people and their luggage. The doors open and close to allow passengers to enter and exit the lift safely.
