Log grapple

Overview
Mounting a hydraulic excavator log grapple significantly increases timber-handling productivity compared with bucket-style grabs. The attachment uses high-strength alloy jaws, dual hydraulic cylinders and a 360° continuous rotator to pick single logs, load bundles and stack timber with precise placement, reducing manual rigging and minimizing bark damage and log slips.

Key design features

• High-strength alloy jaws for secure grip and long wear life
• Dual hydraulic cylinders for balanced clamping force
• 360° continuous rotator for precise log placement
• Multiple model sizes to match carrier tonnage and hydraulic flow

Common jobsite deployments

• Forestry logging and mountain harvesting: clearing fallen trees and skidding logs on steep slopes and trails
• Sawmill and timber yard loading: sorting logs by diameter and feeding cutting lines
• Land clearing and tree removal: grabbing brush, tree stumps and scrap wood
• Pulp mill and firewood processing: handling short firewood logs and pulpwood for continuous feed hoppers

Operator tips

• Grease slewing ring nipples and jaw pin bushings every morning; short greasing intervals significantly extend pin life
• Slow rotator speed on wet or muddy ground to reduce pendulum motion of hanging logs
• On frozen logs, close jaws fully around the log body before lifting
