Introducing the Duxson Grapple Range

Duxson log grapples are constantly evolving to bring new levels of performance and reliability to the market. Professionally designed and built, these grapples are for the high volume application that demands the best. Huge capacity, quick acting, powerful action and long life are just a few features to improve your throughput.

  • High Strength Steel. High strength alloy steel is used throughout the frame and jaws for long lasting durability.
  • Pins. These are induction-hardened alloy steel. All pin joints also have heavy-duty hardened steel bushes — significantly lengthening pin and bearing life.
  • Tight pin tolerances reduce wear and promote long life for the induction hardened pins.
  • Machined Bearing Surface. Precise machining of the bearing surface for the rotator increases the strength of the mounting, reducing side loads on the mounting bolts. Durability and reliability are greatly enhanced.
  • All components are precision machined with large hardened steel bushes used in all pivots.
  • All lower jaw pin retainer bolts are protected with a profiled retainer housing which reduces fastener damage.
  • Excellent physical cylinder protection with precise hose placement for reduced maintenance.
  • Built Tough. Grapple jaws are made of high-strength alloy steel for maximum durability. For additional wear protection, both jaws have hard facing on any high wear areas.
  • Jaw design is optimised to perform in all areas of loading, sorting, shovelling or bunching.
  • Overlapping Jaws. Jaws will close down to a minimum of seven inches — allowing operators the ability to easily handle single, smaller stems.
  • Individual Jaw Pivots. Both jaws have individual pivot points that dramatically reduces the overall stress and increases lifespan.
  • Wide Opening. Best in class opening widths give the user greater operating flexibility.
  • Wear Shims. Shims are fitted to all high wear areas for reduced body wear and smoother operation.
  • 360° Continuous Rotation. High-torque hydraulic motor positions the grapple precisely for rapid sorting and loading. Built-in cross port relief protects the hydraulic system even with heavy loads. Heavy-duty slew bearing for reliability.
  • Internal Routings. Hose connections and supply lines are protected inside the grapple frame, away from the possibility of damage.
  • Hydraulic Cylinders. Heavy-duty wall construction delivers durability and maximum closing power. Bolted glands facilitate both durability and serviceability. Hydraulic Cylinders. GX series grapples feature precision made heavy-duty wall construction with heavy duty hardened steel bushes. This benefit delivers durability and maximum closing power reliability.
  • Direct Connect Fittings. Direct fittings are durable and long-lasting, vastly increasing long-term reliability.
  • Rotating seal joint assembly gives unsurpassed seal life with large sealing areas and specialised high pressure seals.
  • Hose layout between grapple and base machine is compact and neat.
  • Access Panels. Bolt-on access panels protect the grapple internals, but allow easy serviceability in the field.
  • In-the-Field Servicing. All grease points, the motor and other service components are easily accessible in the field with hand tools. Service can be performed quickly, from one position, minimizing downtime.
  • All spare parts are available ex stock for same day dispatch.
  • Easy fit up with various setup options and links available.
  • Optional hose through or non-hose through rotators.
