Hydraulic lifts work on the principle: to rise up, a pump pushes oil into the cylinder, pushing the piston up (which pushes up the lift car). To go down, the valve opens and oil is allowed back into the reservoir, pushing it back using the gravitational force of the hydraulic passenger lift car.
When the valve is closed, the oil can only go from the reservoir into the cylinder. When the valve is open, the oil can only flow from the cylinder back into the reservoir.
The controls in the lift car make the pump work, moving the oil. At the point when a floor is reached, the pump is turned off and the lift car sits on top of the cylinder, held in position by the oil which is caught in the cylinder.
What is a Holed Hydraulic Passenger Lift?
A holed hydraulic lift is a conventional hydraulic lift. ‘Holed Hydraulic’ alludes to the hole needed in the floor for the lift. The cylinder which encases the piston and pushes the lift car extends out into the ground. The distance this extends is equivalent to the distance the lift car can travel upwards.
What is a Holeless Hydraulic Passenger Lift?
A hole-less hydraulic lift means no requirement for a deep pit for the cylinder. The pistons are immediate activity and are mounted on the floor of the pit in accordance with the bottom corners of the lift car. The system works like a jack, and confines travel to around 20-30m at most. This isn’t as normal yet considering use where space is confined going down, travel is short and a hydraulic system is required.
