This grapple has a two prong jaw on one side, and a single jaw on the other.
The jaws and the wear parts are made out of Hardox steel.
Besides lifting stones, this grapple can also be used for the handling of logs.
The form of the jaws is such that the grab also penetrates into piles of brush or
logging slash. The wear plates and the sturdy jaws enable the grapple also be used in
the handling of building debris. The design of the grapple makes it an all-around
utility grapple.
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 Grapple is a bypass design, which enables controlled release of the
load.
