Excavator Mechanical Log Grapple

Excavator Mechanical LogGrapple

Excavator Attachment – Forestry & Scrap Handling

Our excavator mechanical log grapple features a purely mechanical transmission design, directly connecting to the excavator bucket pin shaft without requiring modifications to the existing hydraulic system. It can be operational within 30 minutes of installation. The grapple’s opening and closing are precisely controlled via the excavator’s control lever, with a gripping force of 8-50T. It can easily handle various materials such as timber, construction waste, stone, and steel, enabling efficient “one person, one machine” gripping and replacing 6-8 manual laborers.

Performance Highlights

Detailed Engineering Breakdown

High Wear Resistance
Heavy-Duty Structure
Customizable
Competitive Pricing

Purely mechanical transmission design, easy installation and low maintenance costs

• No hydraulic modification required: No additional hydraulic valve groups or cylinders are needed; installation is simple and can be completed in 30 minutes.

• Simple and durable structure: No complex hydraulic pipelines reduce leaks and jamming; later maintenance only requires periodic inspection of pins and lubrication of bearings, making it 1/5 the maintenance cost of a hydraulic log grapple.

• Low operating threshold: No additional training is required; operators can control the opening, closing, and rotation of the grapple using the excavator's existing control levers, making it quick to learn and even beginners can operate it accurately.

Manufacturing Excellence

High-strength wear-resistant material, service life up to 8000+ hours

Optimal core materials

The gripper body is forged from Q355/Q460/Q690 high-strength steel, capable of withstanding high-frequency gripping impacts; the gripper teeth are made of NM450 wear-resistant steel, with wear resistance three times that of ordinary steel;

Reinforced key components

Gripper teeth

Made of NM450 wear-resistant steel, quenched and tempered for excellent wear resistance and a service life far exceeding the industry average;

application

Application areas

Timber Processing Plant Log Handling
Construction Demolition Waste Sorting
Landscaping Tree Transplantation
Stone Transport In Stone Factories

Timber Processing Plant Log Handling

Utilizing a 15T mechanical log gripper, it can grab two logs with a diameter of 50cm at a time, handling 80 tons of logs per hour, replacing 8 manual laborers, saving an average of 2400 yuan in labor costs per day, and reducing the log loss rate from 5% to 0.5%.
Construction Demolition Waste Sorting

Equipped with multi-toothed grippers, it accurately grabs concrete blocks, steel bars, and other waste materials, sorting 60 tons of waste materials per hour, doubling the sorting efficiency, while avoiding the safety risks of manual sorting, making waste recycling more efficient.
Landscaping Tree Transplantation

Using curved, non-slip grippers, it gently grasps the root ball of trees without damaging the root system, transplanting 15 trees per hour, three times more efficient than manual transplantation, significantly shortening the construction period of landscaping projects.
Stone Transport In Stone Factories

With strong gripping force, it can easily grab 5 tons of stone and transport 100 tons of stone per hour, replacing 6 porters, while avoiding stone collision damage and reducing material loss costs.
