petroleum two stage double acting lifting hydraulic cylinder

### **Product Introduction of Double-End Double-Action Lifting Cylinder**  #### Product Overview   The double-ended double-acting lifting cylinder is a high-performance hydraulic actuator with **bidirectional synchronous drive**, featuring a **symmetrical structure with double piston rods**. It can achieve bidirectional uniform speed and equal thrust movement. Specifically designed for industrial scenarios that require **precise synchronous lifting and large-tonnage balanced lifting**, it is widely used in metallurgical equipment, heavy machinery, special vehicles, and other fields.  ---   ### **Core Advantages** 1. **Bidirectional Balanced Drive** - Dual piston rods extend/retract synchronously, with consistent bidirectional thrust - Lift speed deviation ≤ 3% (Precision guiding system) - Built-in pressure equalizing valve eliminates the impact of uneven loading  2. **Overload Structure Design** - Utilizes **42CrMo alloy steel cylinder**, with rated pressure of 21-35 MPa - Piston rod u…
