An excavator log grapple is a hydraulic excavator attachment designed to grip, lift, stack and transport logs, large bulky objects and miscellaneous materials in forestry yards, sawmills, land clearing sites and material stockyards. YG offers seven model variants covering excavator tonnage from 4 tons to 50 tons, with maximum jaw opening ranging from 1200mm to 2800mm. The grapple adopts an M+S motor, an integrated oil pipe balance valve and SUN hydraulic valve components to maintain stable clamping performance under heavy load conditions, while reducing hydraulic shock and lowering overall failure rate. It supports both electronic control and hydraulic control systems, giving operators flexible control options according to job site requirements.

Core Advantages of Excavator Log Grapple
This series of excavator wood grabber is designed around stable gripping performance, convenient maintenance and long-term durability. Its core advantages can be broken down into the following points:
- M+S motor and integrated oil pipe balance valve: The M+S motor provides reliable power output during continuous grabbing and rotation operations. The integrated oil pipe balance valve helps maintain balanced pressure inside the hydraulic circuit, reduces shaking during lifting and prevents sudden pressure changes when the grapple holds heavy logs.
- SUN hydraulic valve configuration: The excavator wood grabber is equipped with a SUN throttle valve, pressure-reducing valve and overflow valve. These hydraulic valves work together to stabilize oil flow, protect the system from overpressure and keep the clamping force consistent even under uneven load conditions.
- Customizable jaw tooth configuration: Users can choose different jaw tooth layouts according to application needs, including 3+2, 3+4, 2+5 and 3+4+2+5 combinations. Different tooth configurations improve grip stability for logs, irregular bulky objects and mixed miscellaneous materials.
- Dual control system support: Both electronic control and hydraulic control versions are available. Electronic control provides simpler operation and faster response, while hydraulic control offers stable performance suitable for harsh working environments.
- Wide model coverage from 4 to 50 tons: The product line includes seven models with matched jaw opening, cylinder tonnage, oil pressure and flow requirements. It covers small mini excavators, mid-size forestry machines and large heavy-duty excavators used in industrial logging and large timber yards.
Jaw Opening and Material Size
The maximum jaw opening determines what size materials your excavator log grapple can handle.
- 1200-1400mm Opening (Models 02 and 04): These models handle small to medium logs, firewood, brush, and debris. They suit landscaping, tree removal, and light demolition work. The compact jaw size allows operation in tight spaces where larger grapples cannot fit.
- 1600-2100mm Opening (Models 06 and 08): These mid-size digger log grab handles larger timber and commercial forestry operations. Model 06 opens to 1600mm. Model 08 opens to 2100mm. These models suit excavators in the 12-23 ton range.
- 2500-2800mm Opening (Models 10, 14, and 20): These large grapples handle massive timber and heavy-duty forestry work. The 2800mm opening on Models 14 and 20 accommodates the largest logs. These models suit excavators from 24 to 50 tons.
- Material Beyond Logs: The YG series digger log grab handles more than just timber. It grips large objects, demolition debris, scrap metal, and irregular materials. The customizable tine configurations make it adaptable to different material types.
The 360-Degree Rotation Advantage
Rotation capability sets a quality excavator log grapple apart from basic models.
Continuous Rotation: The YG series rotates 360 degrees continuously in both directions. The M+S motor with braking function ensures smooth, controlled rotation even when handling heavy loads. The brake engages automatically when rotation stops, holding the grapple’s position securely.
Precision Positioning: For loading trucks, the operator rotates each log to align perfectly with the truck bed. For stacking, the operator rotates logs to fit neatly into the pile. This precision reduces wasted space and improves load stability.
Reduced Machine Movement: Without rotation, the operator must reposition the excavator to change a log’s orientation. With rotation, the machine stays in one place while the grapple does the positioning. This saves time and reduces track wear.
