In forest logging yards, timber processing plants or ports, we often see a huge “mechanical arm” flexibly grabbing heavy logs and easily completing loading and unloading. This efficient tool is an attachment for excavators — the excavator log grab. It is not only a key accessory for expanding excavator functions, but also an indispensable efficiency tool in modern timber operations.【WhatsApp/WeChat/Phone】+86 13837122632

Mechanical vs Hydraulic Excavator Log Grab
- Different driving principles: The mechanical type directly uses the thrust of the excavator bucket cylinder to open and close. There is no need to change the original hydraulic lines of the excavator; it is ready to use and costs less. The hydraulic type needs a separate hydraulic control line and is driven by a hydraulic motor.
- Functional differences: The biggest advantage of the hydraulic type is 360° continuous rotation. This greatly improves flexibility and precision when handling messy piles of wood. The mechanical type has no rotation function and its movements are relatively simple.
- Cost and maintenance: The mechanical type has a simple structure, low cost and easy maintenance. The hydraulic type uses precision parts such as rotary motors and counterbalance valves, so it costs more, but its adaptability to complex working conditions is unmatched by mechanical types. The key to choosing depends on whether your job requires frequent angle adjustments.
Manual Loading Vs Excavator Log Grab Loading
- Huge difference in efficiency: Traditional manual loading of one truck of wood usually takes 3–4 hours with many workers and heavy labor. With a timber grapple, only one excavator operator is needed, and loading time is shortened to under 1.5 hours — efficiency is increased many times.
- Greatly improved safety: Timber is heavy and easy to roll, so manual handling carries high accident risks. A timber grapple holds wood firmly, keeping operators away from the load and fundamentally preventing crushing and pinching injuries.
- Cost and loss control: Mechanized operation greatly reduces reliance on labor, solving labor shortages and high labor costs. At the same time, precise control avoids damage from collisions during handling and protects wood quality.
How to Choose 2-Tooth, 5-Tooth, 7-Tooth Excavator Log Grab?
- 2-tooth log grab: Wide space between teeth. Suitable for grabbing large, long single or small amounts of wood, such as big logs. It has strong penetration and is easy to insert into wood piles.
- 5-tooth log grab: Balances gripping force and stability. It can grab multiple small and medium-sized logs as well as scattered branches. It has the best versatility.
- 7-tooth log grab: High tooth density and small gaps when closed. Mainly used for grabbing fine materials such as bark, wood chips, sugarcane or construction waste. It prevents small materials from spilling, but may not grip large logs tightly due to too many contact points.
YG Timber Grapple Design Advantages
- Selected materials, precise and durable: We choose steel with different properties based on the stress of each part. For example, the key stressed part — the clamping jaw bending plate — uses high-strength NM400 wear-resistant steel plate, greatly ensuring jaw stability and long service life.
- Core configuration, strong and reliable: For 20-ton timber grapple, we use standard imported Finnish motors with low speed, high torque and brake function. It is also equipped with double counterbalance valves and double relief valves to ensure smooth operation, firm clamping and effective protection of the hydraulic system.
- Fine workmanship, quality guaranteed: Our company uses the industry-leading “post-weld machining” process. This is very different from the rough process of directly welding shaft sleeves and finishing products on the market. Post-weld machining ensures high precision of matching holes and tight fitting of all joints — the key to improving durability.
- Flexible operation, easy control: Considering different operators’ habits, we offer hydraulic control and electromagnetic control for customers to choose from. You can easily control this powerful forestry grapple from the cab.
Forestry Grapple Applications
- Timber processing & logistics: Used for loading, unloading, stacking and feeding logs, veneer and waste in timber markets, paper mills and panel factories.
- Ports & shipping: Used for unloading, transferring and organizing timber ships at ports and docks.
- Construction & demolition: After changing teeth, it can carry formwork, clean waste wood, and even grab steel pipes and concrete blocks on construction sites.
- Recycling & environmental protection: Used for grabbing, sorting and loading waste wooden pallets, packing boxes and other wood waste at recycling stations.
Choosing an excavator log grab means choosing a partner working side by side with you. We know that on dusty job sites, reliability matters most.
