Maximize Performance

Leg profile designed for optimal performance across a variety of tasks. Maximum holding power and control from the cylinder valve. Interlocking legs designed to secure maximum or minimum load. The minimum opening of 5 in. (127 mm) can be used to handle single, small stems. Precise matching of the bearing surface to the rotator increases the strength of mounting, reducing side loads on the mounting bolts. Efficiently align to, grab, pick, and sort with powerful rotations motor and cylinders. Keep your grapple safe while traveling by securing it with the grapple heel preventing swing and impact. Optimal for applications such as: high-volume loading, sorting, high-decking in millyard, and shovel logging.

Rugged Durability

High-strength, alloy steel used to construct grapples for the highest level of durability in tough applications. Get extended use out of your bearings with heavy-duty, lip type excluder seals and sealed pin joints. Long-lasting direct fittings even in extreme conditions. Induction-hardened alloy pins float, decreasing wear. Use a heel with your grapple for maximum productivity: Centered over the hydraulics, hoses are protected by the heel from damage. Maintain control over your load, whether it is one or multiple logs, the flat, serrated rack provides engagement and stability.

Simple Serviceability

Easy-to-replace Hardox® wear strips on the grapple legs. Easy access to grease points and fully serviceable cylinders. Spend more time working with long service intervals and some servicing that can be done in the field with hand tools. Critical components are safe and secure inside the grapple frame. Ensure the integration of your grapple’s hydraulics to the machine’s by having it installed at the factory.

Boost Efficiency and Productivity with Integrated Technologies

Track your entire fleet of attachments and machines from one source. Grapples with asset tracking can be viewed in VisionLink® alongside Product Link™ subscribed equipment. Keep your assets secure. Grapples with a PL161 asset tracker send an alert if they leave an easy-to-setup site boundary.
