Example of grapple used on
mini-excavator, and Gradall Loader

The Valby Grapples can be used to
update log loaders to the modern bypass design. They are also used to convert compact excavators, backhoes and telescopic loaders for log loading use.
The grapples can also be used as components for other log loading machinery such as
skid steer loaders.

It is necessary to install a hanger between the rotator and
the lifting boom. The hanger enables the grapple to swing in two directions which
reduces stress. For more information on hangers, click here.
