INTRODUCING THE
Pierce has substantially refined and strengthened the industry leading TC52, TC58 and TC60 Forestry Grapples.
THE
Pierce has further refined the industry leading TC forestry grapple. A complete and comprehensive design review has led to substantial improvements. From a distance, the grapple does not appear much different from what our customers are accustomed to. However, the structure processes a much stronger design, now. The upper and lower housings are stronger, as well.
The precise leg shape geometry however remains virtually the same. This is a critical benefit on all Pierce grapples and it was important for us to maintain the same curvature on all models.
We’ve also evaluated all components and improved commonality and serviceability. For all upgraded components, they are ‘drop in’ replacements to the previous design – making parts and service support seamless for grapples old and new.
We have implemented these improvements on our most common sizes:
TC52, TC58, TC60.
Availability: Q1 2020.
For those loyal Pierce grapple customers, we are confident that you will further benefit from our newly refined design. And for those new to Pierce grapples, we welcome you to the Pierce family.
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.
