Heavy Duty Excavator Rock Ripper Excavator Ripper Attachment For JCB Case Sany

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

Key characteristics of the excavator rock ripper:

1. Constructed from Q355 manganese plate steel, offering excellent strength and resistance to corrosion.
2. The pin shaft utilizes 42CrMo alloy steel, providing both high strength and toughness.
3. Standard cast bucket teeth are utilized, engineered at optimal angles for effective soil loosening. These teeth are readily available as replacement parts and are secured with bayonet pins for easy disassembly and exchange.
4. The front section of the main body features a standard cast guard plate to protect the ripper’s mainboard during demanding loosening tasks. The guard plate can be easily replaced due to its straightforward fixing method.
5. Irregularly shaped guard plates are welded to the sides of the mainboard, offering enhanced protection that is both robust and durable.
6. At Zhonghe Machinery, we are committed to excellence in meeting the diverse needs of our customers.

Applications of an excavator rock ripper:

• Mining Operations: Essential for breaking up rock and excavating in mining sites.
• Construction Projects: Used for site preparation and excavation in challenging terrains.
• Trenching: Effective for creating trenches for utilities and pipelines in hard ground.
• Road Building: Assists in removing rock and compacted soil for road construction.
• Demolition: Ideal for tearing down structures with solid foundations.
• Landscaping: Utilized for leveling and preparing land in landscaping projects.

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?
