Custom Excavator Attachment Hydraulic Rock Ripper Heavy Duty For Hitachi

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

Main features:
1. Made of Q355 manganese plate steel, it is high in strength and corrosion-resistant;
2. The pin shaft is made of 42CrMo alloy steel, which is high in strength and toughness.
3. Standard cast bucket teeth are used, which are designed at the most suitable angle for loosening soil. Bucket teeth are easy to purchase as wearing parts. Bucket teeth are fixed by bayonet pins and are easy to disassemble and replace.
4. The front end of the main body adopts a standard cast guard plate to ensure that the mainboard of the ripper is protected under harder loosening operations. The guard plate fixing method is simple and easy to replace.
5. Irregular guard plates are welded and fixed on both sides of the mainboard to better protect the mainboard, which is thick and durable.
6. Zhonghe Machinery ripper has been striving for excellence to meet customer needs.

Applications of an excavator rock ripper:

1. Rock Excavation: Used for digging hard rock in mines or quarries, suitable for various types of rock formations.

2. Land Grading: Prepares the ground for construction, especially in areas with boulders or hard soil.

3. Trench Digging: Employed in municipal projects for excavating drainage ditches and other underground infrastructure.

4. Demolition Work: Can be used to demolish solid structures or clear the foundations of abandoned buildings.

5. Agricultural Development: In agriculture, rock rippers can be used to cultivate new land and improve soil structure.

6. Slope and Mountain Excavation: Used in road construction and mountain development to create slopes or excavate mountains

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?
A: Made of Q355 manganese plate steel, it is high in strength and corrosion-resistant; We also can use NM400 materials. The pin shaft is made of 42CrMo alloy steel, which is high in strength and toughness.
