Robust Design Excavator Ripper For Heavy Soil Hard Ground Vibrating And Mining

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

Main attributes of the excavator rock ripper:

1. Fabricated from Q355 manganese plate steel, ensuring high strength and corrosion resistance.
2. The pin shaft is made from 42CrMo alloy steel, known for its toughness and strength.
3. Equipped with standard cast bucket teeth, designed at an ideal angle for soil loosening. These easily replaceable bucket teeth are held in place with bayonet pins, allowing for quick disassembly.
4. A standard cast guard plate is incorporated at the front of the main body, safeguarding the ripper’s mainboard during tough loosening operations. The fixing method for the guard plate is simple and allows for easy replacement.
5. The mainboard is further protected by thick, durable irregular guard plates welded on both sides.
6. Zhonghe Machinery continually strives to excel in fulfilling customer requirements.

Applications of an excavator rock ripper:

• Mining Applications: Crucial for rock fragmentation in various mining operations.
• Heavy Construction: Employed for excavation tasks in large-scale construction projects.
• Utility Installation: Useful for digging trenches for electrical and water utilities.
• Road Construction: Facilitates the removal of rock and debris during road development.
• Demolition Work: Effective for dismantling buildings and structures with strong foundations.
• Site Development: Helps in preparing sites for new developments or expansions.
• Stone Quarrying: Utilized in quarries for the extraction of stone and aggregate materials.

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)

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.
