- The jaws in quality log grapples are made of Hardox steel.
- Every joint in a Valby grapple has a grease fitting and a bronze bushing.
- The Valby grapples have powerful cylinders with heavy pistons.
- Twin connection rods provide good balance and less stress.
- A belly plate protects the cylinder from
below.
- The Valby grapples are of modern bypass grapple design that support
the log from underneath and both sides.
- The Valby bypass grapples enable smooth roll in of the stems.
The jaws close to a tight minimum opening.
Hangers
It is necessary to install a hanger between the rotator and
the lifting boom. The grapple enables the hanger to swing in two directions which reduces
stress. For more information, click here
|
A rotator is usually needed for the attachments.
A rotator enables continuous rotation of the grapple in either direction. Rotators
come in different sizes, depending on the grapple you require. Click here for the options. |
 |
A hanger is mounted between the boom of the excavator
and the rotator. It enables the rotator and grapple to swing in four directions.
