Safe and efficient log handling is a top priority in forestry operations nowadays. Hydraulic log grabs are essential excavator attachments that allow operators to lift, move, and position timber with precision. By reducing manual involvement and optimizing productivity, these tools allow forestry operations to be faster, safer, and more efficient. METDEEM, a trusted manufacturer of forestry and construction machine attachments, offers several models of high-quality hydraulic grapples for heavy-duty applications. The METDEEM DM08 Hydraulic Log Grabs and other models are constructed for strength, precision, and simple mounting on most excavators.
What Are Hydraulic Log Grabs?
Hydraulic log grabs are heavy-duty equipment attachments installed on excavators or machines. They utilize hydraulic cylinders to operate grapple arms (or tines) that securely grasp logs of various shapes and sizes.Key benefits are as follow:
- Effective handling of high volumes of timber.
- Good grip for irregularly shaped logs.
- Reduced manual labor and increased operator safety.
- Faster loading, stacking, and sorting operations.
Key Components of a Hydraulic Log Grab
Main Frame and Arms
The main frame provides the structural strength while the arms (or tines) do the gripping of the logs. In METDEEM, our grapples are lightweight and have a maximum opening size to deal with big material efficiently. METDEEM Log Grabs shells/tines are open or closed based on the application and the material nature to be gripped.
Hydraulic Cylinders and Hoses
These components power the opening and closing of grapple arms. The cylinders convert hydraulic pressure into mechanical force while hoses provide the fluid from the machine’s pump system. In our DM08 Log Grabs, we use heat-treated bushings and pins to maximize strength and wear resistance.
Rotator and Mounting System
Some of the higher-end models have a rotator for 360-degree rotation for added control during use. The mounting system will fit a variety of excavators, making installation simple.
| Component | Function | METDEEM Features |
|---|---|---|
| Main Frame & Arms (Tines) | Structural support and log gripping | Lightweight design, maximum opening for large logs, open or closed shells depending on material |
| Hydraulic Cylinders & Hoses | Convert hydraulic pressure into mechanical force | Heat-treated pins and bushings, sealed bearings for wear resistance |
| Rotator & Mounting System | Enables 360° rotation for better control | Compatible with major excavator brands (CAT, Komatsu, Volvo, Sany, XCMG) |
How Hydraulic Log Grabs Work
Basic Working Principle
Hydraulic log grabs are powered by hydraulic cylinders using an excavator’s auxiliary circuit. Triggered by the operator through controls in the cab, hydraulic pressure causes the cylinders to extend or retract—opening or closing the grapple arms accordingly.
Integration with Forestry Equipment
These attachments can be easily fitted to most modern excavators. The product is well adapted to major domestic and international excavator brands such as CAT, Komatsu, Volvo, Sany, and XCMG, so that you can simply mount METDEEM grapples without needing excessive modifications.
Safety Mechanisms and Controls
Our grapples come equipped with robust locking mechanisms to prevent accidental release of logs during lifting or in motion. The operator has complete control from within the cab for safe operation, even on challenging terrain.
Applications in Modern Forestry Operations
Timber Loading and Offloading
Hydraulic log grabs excel at offloading logs from ground stacks onto conveyor belts or vehicles efficiently and accurately. This reduces manual labor while enhancing workplace safety.
Sorting and Stacking Logs
With precise control over arm movement and grip pressure, operators can sort logs by size or type with ease. Our DM04 model, for instance, offers a 1500mm max opening width—ideal for effectively handling larger sections of timber.
Clearing Land Efficiently
Whether clearing land for replanting or cleaning up after logging operations, hydraulic log grabs help in the clearance of debris efficiently—saving time without sacrificing environmental care standards.
Benefits of Using METDEEM Hydraulic Log Grabs
Durability and Quality of Construction
Constructed using high-strength Q355Mn steel, our grapples are built to withstand harsh conditions prevalent in wooded areas. Skilled welders with over ten years of experience ensure that every unit is structurally sound with no welding cracks. Skilled welders with ten years of experience will ensure no welding cracks for our hydraulic steel grapple.
Precision and Control in Operation
Thanks to perfected hydraulic systems coupled with sealed bearings, METDEEM grapples ensure better grip accuracy—even when handling irregular loads like crooked tree trunks or split logs. The hydraulic design of the grapple ensures better grip for increased productivity and efficiency in the loading cycle.
Compatibility with Various Machines
Our models vary from DM01 (3-4 ton machines) to DM10 (26-35 ton machines), with solutions ideal for small-scale forestry works and industrial-scale logging activities.
Selecting the Ideal Log Grab for Your Application
What to Consider Before Purchase
Considerations are:
- Machine compatibility (tonnage)
- Max jaw opening
- Operating pressure requirement
- Application where it will be used (e.g., sorting or loading)
Make sure your preferred model is compatible with your machine’s hydraulic specification for maximum performance.
Varieties of METDEEM Log Grabs
We have several models available, such as:
- DM01: Suitable for small jobs (3–4 tons)
- DM06: Versatility in medium range (12–16 tons)
- DM10: Heavy-duty application (26–35 tons)
All models are designed with precise flow rates, pressures, and weights—and all have high structural strength under tough conditions.

Maintenance Tips for Longevity
Regular Inspection Checklist
Check hydraulic hoses regularly for abrasions or leaks. Check pins/bushings for wear—especially after periods of heavy-duty operation.
Cleaning and Lubrication Guidelines
Keep all moving parts clear of debris like bark or mud that can cause jamming. Apply grease regularly on pivot points to reduce friction-based wear in the long term.
Troubleshooting Common Issues
If weak grip force is noticed:
- Check hydraulic pressure levels.
- Check cylinder seals.
- Ensure no blockage in hoses or valves.
For abnormal noises during operation:
- Check bearings.
- Verify correct torque specifications on bolts.
Always consult your user manual or contact us directly when issues go beyond general troubleshooting practices.
