Hydraulic double ladder anti-rotating hydraulic telescopic

cylinder lift platform

(1) Working principle of lift platform:

The series of hydraulic lift platform have the advantages of novel design,

small size, exquisite appearance, easy operation and maintenance, stable

ascent and descent, etc. The whole machine consist of platform, telescopic

cylinder, anti-reverse mechanism of double ladder type,chassis oil tank,

supporting leg,road wheel,etc.the telescopic cylinder lifts the platform, when

starting motor, the motor will drive the gear pump 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 constantoperating

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 heigto 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 constantoperating 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 belowthe

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 themagnetic exchange valve can be disconnected at any

position in the descending process, then the platform will stop going down.
