3 Tons Double Column Hydraulic Lift
I、The main functions of the device are described as follows：
① Device for maximum load capacity≧3000kg，Equipment weight≦950kg
② Provisional lift height of tailboard ：1340mm；
① The equipment adopts the electric drive synchronous hydraulic system as the main power source, and the time from the ground operation to the floor plane of the carriage is ≦15 seconds.
Used DC24V dc power;
② The electro-hydraulic system is designed as DC DC12V/24V;
It can directly use the vehicle power;
③ The hydraulic system of the equipment is closed circuit（闭式油路 闭式回路）.
Both cylinders are controlled by the hydraulic system to work synchronously，without a rigid structure.
Synchronous working stroke difference of the left and right cylinders can be controlled at about 15mm;
The error will be automatically corrected for each working cycle during use；
Hydraulic principle is shown in FIG. 6；
