Hitachi tooth point

Types of Hitachi Tooth Points

Hitachi tooth points are pointed teeth used in excavators or digging buckets to facilitate the breaking up of tough or compacted ground when digging. They come in different types that suit diverse industry needs.

• Hitachi Pointed Tooth

  A pointed tooth is designed to break ground or surfaces. It has a sharp point, which exerts a high pressure on the earth, making it easier to penetrate tough soil conditions. The pointed tooth design enhances initial penetration, prioritizing digging efficiency in various projects. This tooth is commonly positioned at the front of digging attachments, such as buckets or blades, to serve as the primary point of contact when approaching or breaking ground.

• Hitachi Standard Tooth

  Unlike the Hitachi pointed tooth that prioritizes penetration, standard teeth focus on weight distribution. They have a flatter design compared to the pointed teeth. Standard teeth fill the space created by the pointed teeth to enhance the digging process. This tooth design also improves the excavation of material previously loosened by the pointed teeth. Standard teeth are typically positioned behind pointed teeth, and they can also be used alone in non-penetration applications where material excavation is needed.

• Hitachi Long Tooth

  Long teeth resemble standard teeth but extend further forward. They enhance reach when digging operations are underway. Additionally, their length improves access to deep or otherwise hard-to-reach areas. Long teeth maintain the traditional tooth design for better material flow and excavation in loose or unconsolidated areas. However, their extended length can place them nearer to the attachment's pivot point, which may result in increased wear due to higher levels of movement and rotation.

• Hitachi Heavy-Duty Tooth

  Heavy-duty teeth are specifically manufactured to enhance wear resistance. They possess durability characteristics to withstand excessive abrasion and impact typical in demanding excavation contexts. Hitachi heavy-duty teeth fit well in high-impact settings, such as quarries or construction sites with compact material. They enhance operational effectiveness and decrease downtime due to frequent replacements in demanding conditions.

• Hitachi Half Arrow

  The half-arrow design resembles a standard tooth but has a unique curved shape. It tapers towards the end, forming a half-arrow appearance. This configuration improves material penetration and movement, particularly in consolidated or semi-consolidated soil. It mimics the function of a standard tooth but offers enhanced versatility in diverse soil contexts. Moreover, half arrows can be used in repair kits to replace worn-out teeth selectively without a full set replacement.

Specification & Maintenance

Some general specifications of a Hitachi tooth point are as follows.

• Material: Usually, the tooth points are made of carbon steel or alloy steel. They may also include some other materials.
• Sizes: The sizes of tooth points can be different. They can be 1 1/4", 1 1/2", 2", and so on. Other sizes are also available.
• Colors: Various colors are available, including the matte color and that with a painting on the surface.
• Type: Usually, there are two common types: the winter type and the summer type.

Maintenance methods of Hitachi tooth points:

• Clean: Make sure to keep the tooth points clean. Before starting work, please make sure there is no dirt or sand on the surface of the tooth points. Also, make sure there is no damage to other parts of the excavators.
• Lubricate: Lubricate tooth points regularly. Lubrication not only can reduce abrasion but also help heat dissipation.
• Replace: Replace Hitachi tooth points by using a wrench or other tools to loosen and remove the bolts. Then, install the new tooth points and fix them with bolts. Please ensure they are securely fixed.
• Inspection: Regularly inspect tooth points to check their status. Take measures to repair or replace them if there are signs of wear or damage.

Scenarios of Hitachi tooth points

Hitachi tooth points and excavators' teeth are crucial in the demolition of solid structures, loading of rocks, digging of trenches and pipelines, excavation of mines, clearance operations, and maintenance of roads. They are also indispensable in the construction of foundations and dams, backfilling, ramp construction, underwater excavation, and sorting and piling of materials.

During the demolition of solid structures, pointed teeth or tip-based tooth points are used to pierce and break solid structures such as concrete ceilings, floors, and walls. For excavation tasks, excavator teeth with cups are used to dig into the earth and hold the excavated material. The design of the teeth allows for easy penetration of the soil and efficient collection of the excavated material.

When it comes to dealing with tough and dense materials such as asphalt and concrete or loosely packed materials such as dirt and sand, different types of excavator teeth are used depending on the situation at hand. For instance, frost or rock digging will require a pointed tooth known as a frost or rock tip, which is designed for digging in frozen ground or rocky soil.

Excavator teeth also come in different sizes. The size of the excavator tooth required for a task depends on factors such as the material density, temperature, and space constraints. For instance, ripper teeth are basically excavator teeth that are used in snowy, frozen, and sandy soils. They are wider than traditional excavation teeth, and one to three of them can be found on a ripper attachment behind an excavator or a loader. If a job requires excavation in these types of soils, these teeth will be used.

Excavator teeth also work differently depending on the excavator attachment. Common excavator attachments that use excavator teeth include:

• Digging Buckets:Standard bucket attachments used for general excavation tasks.
• Heavy-Duty Digging Buckets:Used for more demanding excavation projects and specialized attachments for specific applications, such as bucket hooks for tractor buckets, PVC lined buckets for waterfall excavation, and skeleton buckets for sorting and separating materials.
• Trenching Buckets:Used for digging narrow and deep trenches, usually for utility installations or drainage work. They are designed to excavate clean, defined trenches with minimal soil disturbance.
• Sump Buckets:They are used for drainage or excavation of sumps and are designed to dig out areas to allow for water flow and prevent flooding.
• Ditching Buckets:
• Rippers:Similar to excavator teeth, rippers have a larger size. They are used to make an initial crack in the ground. They are curved steel shanks mounted to a horizontal beam. They can be found on backhoes and track hoes. An excavator with a ripper on it can be used to make a demolition process easier and can reduce the cost and time needed for the process.
• Hydraulic Hammers:Used to break and demolish solid structures.
