Hydraulic double ladder anti-rotating hydraulic telescopic cylinder lift platform
(1) Working principle of lift platform:
 When the platform rises to the highest position, the system pressure will reach a rated operating pressure. At this moment, relief valve unloads and oil pressure remains a constant operating pressure.
 After the machine stops, as the one-way valve maintains pressure, the platform will stay at the position of maximum height. The platform can stop at any position below the maximum height according to onsite operating high to supply oil, and the oil will flow into cylinder through one-way valve and electromagnetic channel, as a result, the telescopic cylinder rises joint by joint. When the platform rises to the highest position, the system pressure will reach a rated operating pressure. At this moment, relief valve unloads and oil pressure remains a constant operating pressure.
After the machine stops, as the one-way valve maintains pressure, the platform will stay at the position of maximum height. The platform can stop at any position below the maximum height according to onsite operating height. As the platform goes down, its dead weight presses the oil into oil tank through magnetic exchange valve. When connecting magnetic exchange valve, the telescopic cylinder will goes down joint by joint, or the magnetic exchange valve can be disconnected at any position in the descending process, then the platform will stop going down.
