- Hardox is a prime steel used in the manufacture of high
quality log grapples.
- All Valby grapples have a bronze
bushing at every joint, and every joint has a grease fitting.
- Large, powerful cylinders.
- Double connection rods provide good balance and less stress.
- A belly plate protects the
cylinder from underneath.
- Modern bypass grapple design
- The Valby bypass grapples have excellent geometry. The form
of the claws enables a smooth roll in of the stems. The grapples also close to a tight
minimum opening.
