Heavy-Duty Mechanical Demolition Grapple for Excavator with Replaceable Teeth

The TianGe Heavy-Duty Mechanical demolition grapple is designed for contractors who regularly handle concrete, rocks, reinforced demolition debris and other hard, irregular materials. Unlike general-purpose mechanical grapples, this model features a reinforced frame, heavy-duty tines and replaceable bucket teeth, providing greater durability in demanding working environments.

Built for excavators from 3 to 23 tons, this excavator mechanical grapple operates through the excavator bucket linkage and requires no auxiliary hydraulic circuits. The simple mechanical design reduces maintenance costs while delivering dependable gripping performance for heavy-duty demolition, rock handling, quarry operations and construction waste recycling.

One of the biggest advantages of this attachment is its replaceable tooth system. Similar to excavator bucket teeth, worn tooth tips can be replaced individually instead of repairing or replacing the complete grapple. This significantly lowers long-term maintenance costs, especially in abrasive working conditions involving concrete, natural stone and reinforced materials.

In North America, this attachment is commonly referred to as a Mechanical Demolition Grapple or Mechanical Rock Grapple. It is widely selected by demolition contractors, recycling companies, quarry operators and construction firms that require a durable mechanical grapple capable of handling oversized, heavy and irregular materials.

Specifications

The Heavy-Duty Mechanical Grapple series is available in five models covering excavators from 3 to 23 tons. Each model is designed to provide sufficient jaw opening and structural strength for demanding demolition and rock handling applications while maintaining reliable gripping performance.

TG-HMG30 is recommended for compact demolition projects, masonry removal and light concrete handling on 3–4 ton excavators.

TG-HMG50 is suitable for residential demolition, concrete cleanup and handling medium-sized rocks on 4–6 ton machines.

TG-HMG70 offers increased gripping capacity for reinforced concrete, construction debris and recycling applications using 6–8 ton excavators.

TG-HMG120 is designed for professional demolition contractors working on commercial buildings, bridge maintenance and heavy construction waste with 12–16 ton excavators.

TG-HMG200 provides maximum gripping force and durability for quarry operations, oversized rocks, reinforced concrete and demanding demolition work on 18–23 ton excavators.

All models can be customized with different pin dimensions, mounting widths and quick coupler configurations to fit most excavator brands.

Key Features

The TianGe Heavy-Duty Mechanical Demolition Grapple is engineered for demanding applications where ordinary mechanical grapples wear quickly. Its reinforced structure and replaceable tooth design make it an excellent choice for contractors handling abrasive materials every day while keeping maintenance costs under control.

• Replaceable Bucket Teeth
  Equipped with replaceable bucket teeth similar to excavator buckets. Worn tooth tips can be replaced individually, reducing maintenance costs and extending the service life of the grapple body.

• Heavy-Duty Reinforced Structure
  Built from high-strength wear-resistant steel with reinforced pivot areas to withstand continuous impact from concrete, rocks and demolition debris.

• No Auxiliary Hydraulic Circuit Required
  Operates through the excavator bucket linkage without hydraulic cylinders, hoses or additional control valves, making installation simple and reducing ownership costs.

• Powerful Gripping Force
  The optimized mechanical linkage provides excellent clamping force for irregular materials including broken concrete, natural stone, concrete blocks and large construction debris.

• Designed for Abrasive Working Conditions
  Ideal for demolition sites, recycling plants, quarry operations and construction projects where attachment durability is critical.

• Lower Lifetime Maintenance Cost
  The replaceable wear parts help minimize repair downtime and eliminate the need to rebuild the entire grapple after tooth wear.

• Fits Multiple Excavator Brands
  Available with customized pin dimensions and mounting configurations for most excavator brands and quick coupler systems.

Applications

The Heavy-Duty Mechanical Demolition Grapple is designed for contractors who regularly work with hard, oversized and irregular materials. Compared with a general-purpose mechanical grapple, this model provides greater durability and wear resistance in demanding environments.

• Heavy-duty building demolition and structural dismantling.

• Handling reinforced concrete, concrete blocks and construction debris.

• Loading oversized rocks, boulders and quarry materials.

• Sorting demolition waste before crushing or recycling.

• Concrete recycling plants and construction waste transfer stations.

• Bridge renovation, road reconstruction and infrastructure demolition.

• Industrial demolition projects requiring durable mechanical attachments.

• Mining support and heavy material handling where replaceable wear parts reduce maintenance costs.

How to Choose the Right Heavy-Duty Mechanical Grapple

Selecting the correct Heavy-Duty Mechanical Demolition Grapple depends on your excavator size, the hardness of the material being handled and the intensity of your work. Choosing the proper model improves gripping performance, machine stability and attachment service life.

If your primary work involves logs, brush, roots or everyday material handling, a General Purpose Mechanical Grapple is usually the better option because it offers lower weight and greater versatility.

If your projects regularly involve reinforced concrete, demolition debris, quarry stone or abrasive materials, this Heavy-Duty Mechanical Grapple with replaceable teeth will provide better durability and lower long-term maintenance costs.
