Linkage & Hydraulic Cylinders for Ripper Systems

Product Specifications

Technical details and manufacturing context for Linkage & Hydraulic Cylinders

Definition

This component assembly is a critical part of ripper systems used in construction and mining equipment. It connects the ripper shank to the main frame, enabling precise control over the depth, angle, and force applied during ground penetration and material breaking. The system consists of a linkage mechanism and hydraulic cylinders. The linkage provides mechanical advantage and guides the movement of the shank, while the cylinders supply the necessary force for penetration and lifting. The assembly is designed to withstand high loads and harsh operating conditions. Key materials include high-strength alloy steel for structural components, chromium-plated piston rods for wear resistance, and seal materials such as polyurethane or nitrile for reliable sealing. The operating pressure typically ranges from 1.0 to 1.6 MPa, with cylinder bore diameters from 50 to 200 mm, stroke lengths from 100 to 1000 mm, and rod diameters from 25 to 100 mm. The system operates within a temperature range of -20°C to 80°C. Maximum pull force is 50 to 300 kN, and maximum push force is 80 to 500 kN. Cylinder material is typically ST52-3 per DIN 17100, rod material is 45# per GB/T 699, and seal material is NBR per ISO 1629. Cylinder weight ranges from 20 to 150 kg. Mounting type is clevis per ISO 6982. Surface finishes are Ra 0.2–0.4 µm for piston rods and Ra 0.4–0.8 µm for cylinder tubes per ISO 1302. These values are reference ranges; verify model-specific specifications with the manufacturer.

Working Principle

Hydraulic fluid pressure extends or retracts the cylinders, which in turn moves the linkage system to position the ripper shank. The linkage provides mechanical advantage and controlled movement while the cylinders supply the necessary force for penetration and lifting. The system allows precise control of the ripper's depth and angle, enabling efficient ground breaking and material handling.

Frequently Asked Questions

What is the function of the linkage and hydraulic cylinders in a ripper system?

The assembly connects the ripper shank to the main frame and uses hydraulic cylinders to control the depth, angle, and force applied during ripping operations. The linkage provides mechanical advantage and guides the shank's movement.

What materials are used in this component?

High-strength alloy steel is used for structural parts, chromium-plated piston rods for wear resistance, and seal materials like polyurethane or nitrile. Specific grades include ST52-3 for cylinders, 45# for rods, and NBR for seals.

What are the typical operating parameters?

Operating pressure is 1.0–1.6 MPa, bore diameter 50–200 mm, stroke 100–1000 mm, rod diameter 25–100 mm, temperature -20 to 80°C, pull force 50–300 kN, push force 80–500 kN, and weight 20–150 kg. These are reference ranges; verify for your model.

How should I verify the specifications for my application?

Always check the manufacturer's datasheet or technical manual for the exact model. Standards like ISO 6020-2, ISO 6022, and ISO 4413 provide guidelines, but actual values must be confirmed with the supplier.
