The electro hydraulic used by LUXMAIN Underground car Lift, it works differently from air hydraulic, the hydraulic oil in the oil circuit is driven directly by the motor/pump station to make the cylinder work.
Speed: The compression rate of air much more than hydraulic oil, so the rise/fall rate is uneven and slow in response. With the same elevation to 1.8 meters, the electro-hydraulic device would take about 45 seconds but the air hydraulic device would take 110 seconds.
Stability: electro-hydraulic driven by liquid, rising rate uniform, no shaking; And air hydraulic has ”aerodynamic resistance”, the external temperature and the oil density is different, the compression ratio is not the same. Shake is inevitable in the process of cylinder rise/fall.
Oil consumption: General electro-hydraulic device only needs about 8 liters of hydraulic oil; air hydraulic equipment generally requires 150 to 160 liters of hydraulic oil. And when changing the air hydraulic device oil, especially the air hydraulic Inground car Lift, because the hydraulic oil is stored in the cylinder, and the cylinder is buried underground, replacement is very laborious, needing pumping unit to extract, which makes the labor cost is very high. Electro hydraulic will generally store hydraulic oil in the ground power unit/electric control cabinet tank, operation is very simple.
Safety: Because the principles of the two devices are different, so the internal structure is completely different. The electro-hydraulic inground car lift can be equipped with a hydraulic throttle plate, which is a hydraulic buffer insurance measure when falling, and can be equipped with a mechanical lock, double insurance. The air hydraulic cannot be equipped with mechanical locks, and the whole surpping arms and the car can rotate 360 degrees before the piston reaches the top, which is very unsafe for any operation.
