RCH Series 20-100 Tons Hydraulic Jack Hollow Plunger Hydraulic Cylinder

The RCH Series 20-100 Tons Hydraulic Jack, characterized by its hollow plunger hydraulic cylinder, is an indispensable tool in various industrial applications where high-capacity force is required. This hydraulic jack is designed to provide both pushing and pulling force, making it versatile for a range of tasks.

Functionality and Features:

1. Hollow Plunger Design: The standout feature of the RCH Series is its hollow plunger design. This allows the hydraulic jack to be used for both pulling and pushing operations. The hollow cylinder can accommodate a cable, chain, or a bar, which makes it ideal for applications where the load needs to be moved or lifted through the center of the cylinder.

2. Single-Acting Operation: The hydraulic jack operates on a single-acting principle, which means it uses a single hydraulic chamber for extending the plunger. The retraction is achieved through a spring or by releasing the pressure, making the operation efficient and the tool cost-effective to use.

3. Corrosion-Resistant Paint: The exterior of the hydraulic jack is coated with a high-quality, baked-on paint finish. This not only gives the tool a professional appearance but also provides a robust layer of protection against rust and corrosion, ensuring longevity even in harsh working environments.

4. External Threaded Ports: The RCH Series features external threaded ports for easy connection to hydraulic hoses. This design simplifies the setup process and allows for quick and secure attachment, reducing the risk of leaks and improving the overall efficiency of the hydraulic system.

Construction and Material:

The RCH Series is constructed with high-strength steel, ensuring that it can withstand the heavy loads and pressures involved in its operation. The cylinder wall thickness is optimized to provide a balance between strength and weight, contributing to the jack's portability.

Safety Features:

Safety is a paramount consideration in the design of the RCH Series. It includes built-in safety valves to prevent overloading and a pressure relief system to protect the operator and the equipment from excessive pressure. The jack also features a lockout device to hold the load securely in place during the work.

Applications:

The versatility of the RCH Series hydraulic jack makes it suitable for a wide range of applications, including:

- Lifting and positioning heavy machinery and equipment.
- Pulling and pushing in construction and civil engineering projects.
- Use in automotive repair shops for lifting vehicles.
- In marine and offshore applications for heavy lifting and maintenance tasks.
- For bending, straightening, or aligning heavy structural components.

Maintenance and Operation:

Proper maintenance is crucial for the longevity and safe operation of the RCH Series hydraulic jack. Regular inspection of the cylinder, seals, and connections should be performed. The hydraulic fluid should be clean and changed according to the manufacturer's recommendations to prevent contamination and wear.

Operation of the hydraulic jack is typically straightforward, with a hydraulic pump supplying the necessary pressure to extend the plunger. The retraction is usually achieved by releasing the hydraulic pressure or using the spring return mechanism.

The RCH Series 20-100 Tons Hydraulic Jack with its hollow plunger design is a powerful and versatile tool that offers high performance and reliability. Its single-acting operation, corrosion-resistant finish, and convenient external threaded ports make it a preferred choice in many heavy-duty applications. With proper use and maintenance, this hydraulic jack can significantly enhance productivity and safety in various industrial settings.
