An elevator is a simple electrical machine in its principle. Going by that definition, we can say that a passenger lift is a platform that goes up and down ferrying passengers. With electrical systems to choose desired floors and safety system to allow smooth vertical travel.

Emperor Lifts manufactures all types of elevators like Passenger/Hospital/Freight/Home lifts using Traction and hydraulic lifts. Let us read more about the working principle of both the elevator systems over the next two articles.

Types of passenger lift

Hydraulic elevators

The hydraulic elevators work on the hydraulic cylinder principle that uses hydraulic fluids to push a piston inside a cylinder that in turn raises and lowers the passenger lift. The hydraulic fluids like oil or other in compressible fluids are used.

This system requires an electrical pump to push the hydraulic fluid from the reservoir into the cylinder. The fluids compression pushes the piston which in turn raises the passenger lift. At the desired floor the valve on the cylinder closes and the piston just rests on the fluids. The elevator door opens. The valve opens again thrusting the hydraulic fluids to move the passenger lift to higher floors through the piston movement.

While descent the valve opens, and the hydraulic fluids slowly move back to the reservoir lifting the pressure off the piston. This mechanism allows the slow descent of the elevator to lower floors. To stop the elevator at any desired lower floor, the valve shuts and the piston stops moving.  With this the elevator can be stopped at any desired lower floor too.

This is a cost-effective solution for buildings with fewer floors. Ideal for a residential building or a small departmental store. Get your quote for hydraulic elevators from Emperor Lifts today.
