INTRODUCING THE
NEW SERIES
FORESTRY GRAPPLES
Pierce has substantially refined and strengthened the industry leading TC52, TC58 and TC60 Forestry Grapples.
THE
NEW SERIES
FORESTRY GRAPPLES
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.
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.
GENERAL
- 30 years and thousands of Pierce grapples in operation prove our superior design in extreme North American timber and conditions.
- Superior payload capacity.
- Utilized by road builders, forestry and logging contractors, millyards and sortyards.
STRUCTURE
- Resilient, wear and impact-resistant steel used throughout.
- Precision machining provides proper fi t and interchangeability of replacement components.
GRAPPLE ARMS
- Heavy-duty grapple arms designed for the rigors of shovel logging, loading, sorting and multi-stem handling.
- Single center pivot pin design requires less maintenance and offers small grapple closure.
- Grapple’s arm shape allows for easy and gentle digging into log decks.
- Small grapple closure for superior single-stem handling.
- Handles tree length or cut stems.
- Logs roll up into “throat” for greater payload control, regardless of log diameter.
- Hardened, wear-resistant grapple arm tips.
PINS & BUSHINGS
- Oversized, induction hardened, heat treated, and chromed pins.
- Aluminum bronze bushings for extended lubrication and greasing intervals.
ROTATION
- 360º continuous rotation.
CYLINDERS
- Sized to recommended machine operating pressure.
- Load check valves reduce risk of losing your payload in the event of a pressure loss.
- High-pressure piston seals.
- Heavy-duty protection of both arm cylinders.
HYDRAULIC SYSTEM
- Completely enclosed hydraulics with easy serviceability behind bolt-on service covers.
MAINTENANCE
- Component commonality between all Pierce TC models for ease of serviceability and support. A benefit for customers that have multiple grapples
- Simple design allows for easy servicing and maintenance.
