GRAPPLES
Power Clam
Your loader is the heart of your logging operation, so you need a grapple that supports maximum productivity. With a Viking West G-Series power clam grapple on your loader, you can count on exceptional performance in the most demanding forestry conditions.
Forestry grapples are expected to handle extreme loads in the toughest conditions. We spend countless hours testing our G-Series power clam grapples in real-world conditions to ensure that they won’t let you down. In addition, detailed analysis of strain gauge results ensure that our finite element analysis models are accurate and our trouble-free life predictions are reliable.
Our G-Series power clam grapples are designed for maximum flexibility. Whether you are looking for 8, 10 or 12 cubic foot jaws, planning to attach to your carrier with wedge lock or direct pin on lugging, or wanting to use our standard fixed outriggers or optional hydraulic outriggers to handle full-length timber, these options are easy to configure at the time of order or implement later when the need arises.
Moving wood faster means increased demands on your grapple and dramatically increased forces on the main bearing. Viking West is the first grapple manufacturer to provide a heavy-duty double-row main bearing, which comes standard on all G-Series power clam grapples.
Our thumb cylinders are designed and individually proof tested to 5800PSI for use with modern excavator high-pressure hydraulic systems.
Our G-Series power clam grapples feature an AMCA control valve, which has a superior design for high-vibration applications. This valve utilizes precision dowels to lock individual sections to each other, thereby greatly reducing susceptibility to leaking between sections caused by vibration and mounting surface flex.
Our G-Series power clam grapples feature dual Eaton VIS motors complete with precision ground drum profile pinion teeth for optimal tooth loading and extended life.
Our bull nose grapple tips minimize damage to timber during loading, thereby protecting the value of your timber and are easily replaceable in the future if you wear them out.
Every Viking West G-Series power clam grapple comes with an industry-leading 24-month warranty. If you need our support, we promise to have service parts in stock and qualified technicians available to get you back up and running.
