custom round small home elevator for modern popular design style

Hydraulic drive is an earlier elevator drive. Early hydraulic elevator drive medium is water, the use of water is incompressible by pressurizing the water pressure, with a certain pressure of water access to the cylinder, push the cylinder plunger lifting the car, so that the car upward running; through the drain valve to open the drain, the car in the role of self-weight down. But because the water pressure contains air bubbles will produce fluctuations and cylinder rust problem is difficult to solve, and then use oil as a medium to drive the plunger to do linear motion. Because the hydraulic elevator lifting force is large, can provide high mechanical efficiency and low energy consumption, so for short trips, heavy load occasions, the advantages of use are particularly obvious. In addition, because the hydraulic elevator does not have to set up a machine room on the roof of the building, reducing the vertical size of the shaft and effectively utilizing the building space, the hydraulic elevator has a broader application prospect. Nowadays, hydraulic elevators are widely used in parking lots, factories ,small space and low-rise buildings. For the occasions of large load, slow speed and short stroke, hydraulic elevator is more economical and suitable than traction elevator.
