Double Acting Flange Lifting Hydraulic Jack
Double Acting Flange Lifting Hydraulic Jack is a robust and durable integrated hydraulic cylinder designed for harsh industrial environments. Its main advantages lie in its powerful and precise control during the lifting cycle, as well as its stable, built-in mounting design via the flange, making it a key component of robust and reliable mechanical equipment.
Double acting flange lifting hydraulic jacks are lifting devices that achieve bidirectional movement through a hydraulic system. Their core features are:
1. Bidirectional Drive: Both piston extension and retraction are driven by hydraulic oil pressure, eliminating the need for gravity or spring reset, increasing efficiency by approximately 50% compared to single-acting jacks.
2. Flange Structure: Equipped with flanges on the bottom or side, facilitating bolt fixation to equipment or foundations, enhancing stability, and suitable for long-term loads or high-frequency vibration scenarios.
3. Pascal’s Principle Application: Pressure is transmitted to the hydraulic cylinder via a hydraulic pump, utilizing the incompressibility of fluids to amplify force and meet heavy-duty lifting requirements.

Double acting flange lifting hydraulic jacks advantages:
1. High-Efficiency Bidirectional Operation: Extension and retraction are both hydraulically driven, reducing manual intervention and shortening the work cycle. For example, in bridge construction, it allows for rapid completion of cable tensioning and anchoring.
2. Strong Structural Stability: The flange fixing design reduces the risk of slippage, making it suitable for long-term support of heavy objects (such as equipment installation and static pile driving). 3. Customization Capability
Supports customization of load capacity, stroke, and installation methods (such as lugs, feet, universal joints), adaptable to various scenarios including agricultural machinery, industrial equipment, and construction engineering.
4. Safety and Durability
Equipped with safety valves, dust rings, and hard chrome-plated plungers to prevent overload and contamination, seals use O-rings or combination seals, with a leakage rate of less than 0.1%.

Double acting flange lifting hydraulic jacks application scenarios:
1. Bridge and Tunnel Engineering
Used for cable tensioning and concrete component lifting, such as using through-hole jacks with anchors to complete prestressed construction.

2. Heavy Equipment Maintenance
Supports and adjusts the level of large machinery (such as die-casting machines and injection molding machines) to ensure accuracy.
3. Static Pile Driving and Lifting
In building foundation construction, multiple synchronous jacks are used to achieve vertical driving of pile foundations or overall lifting of buildings.
4. Agricultural and Industrial Machinery
Customized small double-acting jacks are used for agricultural machinery lifting (such as harvester header adjustment) or material handling in industrial automated production lines.
