Specialized Tip Design Digger Hydraulic Ripper For Mining And Excavation

Applicable objects: Loosening operations in harder soil layers, frozen soil layers, soft rocks, weathered rocks and other geological conditions

Highlighted features of the excavator rock ripper:

1. Constructed from Q355 manganese plate steel, ensuring high strength and corrosion resistance.
2. The pin shaft utilizes 42CrMo alloy steel, known for its exceptional strength and toughness.
3. Features standard cast bucket teeth, designed at optimal angles for loosening soil. These bucket teeth are available for easy purchase as wear parts and are fixed with bayonet pins for simple replacement.
4. The main body’s front section includes a standard cast guard plate, protecting the mainboard during challenging operations. The guard plate is easy to fix and replace.
5. Irregular guard plates welded on both sides of the mainboard offer additional protection that is robust and durable.
6. At Zhonghe Machinery, we strive for excellence to fulfill the needs of our customers.

Applications of an excavator rock ripper:

• Mining Operations: Essential for breaking hard rock in various mining contexts.
• Construction Projects: Employed for tough excavation tasks at construction sites.
• Utility Trenching: Useful for digging trenches for utilities like gas and water.
• Road Building: Aids in removing rock and soil during road construction.
• Demolition: Ideal for tearing down structures with solid foundations.
• Land Development: Prepares land for new construction or landscaping projects.
• Quarrying Activities: Vital for extracting stone and minerals in quarry operations.

What is the purpose of a long arm plate bevel?

The purpose of a long arm plate bevel is to facilitate the welding process, ensuring a stronger and more reliable weld that extends through the full thickness of the material. Here are the key reasons for using a bevel on a long arm plate:

1. Improved Weld Penetration: As you mentioned, welding machines typically have a depth of fusion that is less than the thickness of the plate. A bevel allows the welding arc to reach further into the material, achieving better penetration and ensuring that the weld fills the entire joint.

2. Preventing Weld Cracking: Without a bevel, the weld may not penetrate fully, leaving a weak spot in the weld that could lead to cracking under stress. A proper bevel ensures that the weld is continuous and free of defects that could cause future failures.

3. Reducing Welding Time: A beveled edge can reduce the amount of material that needs to be melted, which can decrease the time required to complete the weld.

4. Enhancing Weld Quality: The bevel provides a consistent edge for the welder to work with, which can lead to a more uniform and aesthetically pleasing weld.

5. Mechanical vs. Manual Beveling: Mechanically cutting bevels is generally more precise than manual methods. This precision is critical for ensuring the quality of the weld. A mechanically cut bevel provides a cleaner, more uniform edge that can be more easily and consistently welded.

Factories that use mechanical beveling over manual beveling often produce products with higher quality and consistency. The mechanical process reduces human error and provides a more reliable bevel that is critical for structural integrity, especially in heavy-duty equipment like excavator long arm plates.

We make bevels mechanically, while other factories make bevels manually (as shown in the picture)

High precision machine of Zhonghe Machinery Manufacturers

Large Floor-Standing Double-Sided Boring and Milling Lathe:

• Improved Accuracy and Consistency: The double-sided boring and milling lathe enhances the precision and uniformity of operations, ensuring consistent results.
• Post-Welding Processing: After the welding process, the machine performs overall boring, ensuring the parallelism and perpendicularity of shaft holes.
• Primary Applications: Primarily used for post-weld boring of the boom, small arm, and bucket, ensuring the accuracy and proper alignment of the boom.
• Simultaneous Boring on Both Sides: The lathe performs boring on both sides at the same time, guaranteeing identical precision and consistency on both sides.

Q: What material is the excavator rock ripper made of?
