Mounting a heavy excavator log grapple boosts timber loading speed by more than three times compared to bucket grabs. Manual rigging and bucket scoops move slowly on logging sites. They often damage tree bark and risk dangerous log slips.
A hydraulic log grapple features high-strength alloy jaws, dual hydraulic cylinders, and a 360-degree continuous rotator. It picks single logs, loads timber bundles, and stacks piles cleanly in one smooth work cycle. This specialized attachment cuts labor effort and lowers overall jobsite costs fast.
How Do You Select an Excavator Log Grapple by Technical Specifications?
Selecting an excavator log grapple requires matching carrier tonnage, max jaw opening, hydraulic oil pressure, and operating flux. Review the official specification table below:
| Model | Suitable Excavator | Attachment Weight | Max Jaw Opening | Oil Pressure | Set Up Pressure | Operating Flux | Cylinder Volume |
| 02 | 4 – 6 Ton | 360 kg | 1200 mm | 160kg/cm² | 170kg/cm² | 30 – 55 L/min | 4.0×2 Ton |
| 04 | 7 – 11 Ton | 440 kg | 1400 mm | 160kg/cm² | 180kg/cm² | 50 – 100 L/min | 4.5×2 Ton |
| 06 | 12 – 16 Ton | 900 kg | 1600 mm | 180kg/cm² | 190kg/cm² | 90 – 110 L/min | 8.0×2 Ton |
| 08 | 17 – 23 Ton | 1680 kg | 2100 mm | 180kg/cm² | 200kg/cm² | 100 – 140 L/min | 9.7×2 Ton |
| 10 | 24 – 30 Ton | 2130 kg | 2500 mm | 180kg/cm² | 210kg/cm² | 130 – 170 L/min | 12.0×2 Ton |
| 14 | 31 – 40 Ton | 2600 kg | 2800 mm | 180kg/cm² | 250kg/cm² | 80 – 120 L/min | 12.0×2 Ton |
| 20 | 41 – 50 Ton | 2800 kg | 2800 mm | 200kg/cm² | 250kg/cm² | 80 – 120 L/min | 14.0×2 Ton |
Operator Tip: Grease slewing ring nipples and jaw pin bushings every morning. Three minutes of greasing adds two full years to pin service life!
Where Do Contractors Deploy an Excavator Log Grapple on Jobsites?
- Forestry Logging and Mountain Harvesting: On steep slopes and forest trails, an excavator log grapple clears fallen trees and skids logs efficiently.
- Sawmill and Timber Yard Loading: Crews run a hydraulic timber grapple for excavator to sort logs by diameter and feed cutting lines with high precision.
- Land Clearing and Tree Removal: In municipal clearing jobs, operators grab brush, tree stumps, and scrap wood quickly.
- Pulp Mill and Firewood Processing: Outfitted with smaller jaws, the tool grabs short firewood logs and pulp wood for continuous feed hoppers.
Operator Tip: Slow down rotator speed on wet forest mud. Fast swings swing hanging logs like hammer throws into your cab!
How Did an Excavator Log Grapple Help a Canadian Forestry Project?
- Jobsite Challenge: Timber yard manager Mark in British Columbia, Canada faced high winter labor expenses. His old clamp lacked grip on slippery frozen logs. Logs dropped constantly, limiting output to just 2 trucks per hour under strict shift limits.
- Equipment Solution: YG Machinery engineers fitted a Model 06 hydraulic timber grapple for excavator (900kg weight, 1600mm opening, 8.0×2 Ton cylinder output) onto his 14-ton digger.
- Real Business Results: Jaw clamping power doubled, cutting truck loading time by 60%. Loading output jumped to 5 trucks per hour. The crew saved over 18,000 CAD in labor and overtime during the first month.
Operator Tip: Ice on frozen logs slips easily. Lock jaws fully around the log body before lifting your stick!
Frequently Asked Questions About Excavator Log Grapple Selection
No. The grapple must match excavator tonnage, lifting limits, and oil flow. Oversized grapples stress the excavator arm, while undersized units waste machine power.
The setup requires two auxiliary dual-way hydraulic lines (4 hoses in total). One circuit opens and closes the jaws, while the second line turns the 360-degree rotator motor.
According to technical specs, Model 06 is built for 12-16 ton diggers. It delivers a 1600mm max jaw opening, runs at 90-110 L/min oil flow, and features 8.0×2 Ton cylinder volume.
