BUILT ON MORE THAN 30 YEARS OF INPUT FROM LOGGERS LIKE YOU.

For more than 30 years, Pierce has been manufacturing hydraulic forestry grapples using input from professional loggers like you. As machinery and loggers get stronger, so do our grapples. The result is a product that does all the things you need it to do, easily and efficiently. Pierce twin cylinder forestry grapples feature powerful 360° continuous rotation and are multi-purposed for excellent versatility. They feature an optimum arm shape for big wood, tight grapple closure for superior small log control, load check valves to eliminate the risk of dropping your payload, and heavy-duty legs that possess the optimum shape for shovel logging, loading, unloading and sorting.
