Hypro - Model FG45 - Felling Grapple/Energy Felling Grapple
From Felling Grapple
HYPRO Felling grapple is very well suited for handling anything from standing trees to fallen logs. The felling grapple can be mounted on all cranes equipped with rotator. The felling grapple fells standing timber with a normal length of up to 30–35 cm in diameter and has cutting capacity for trees with swollen roots as well as forest consisting of shorter trees under favourable conditions up to 45 cm in diameter, which makes it absolutely unique in function for its small weight and size.
HYPRO FG45 is also available as energy-wood felling grapple, which is equipped with a special sword to make it possible to cut both small shrubberies and all the way up to 35 cm thick trees.
HYPRO FG45 automatically tilts the grapple up to felling position when the grapple claws reach maximum open position. If one wishes to lower the grapple back to horizontal position, one does only need to activate the cutting function and the grapple falls back to horizontal position instantly.
The valve block of the crane needs to be supplemented with an extra valve for the activation of the saw motor. This extra valve must be a motor slide model which is open to the tank line in neutral position.
The flexibility of the swift hydraulic spine of the felling grapple makes it possible to reach tree trunks in the correct felling direction. This also delivers a very rational an easily maneuvered felling experience.
Furthermore, the light weight of the felling grapple makes it possible to use the crane to its full extent without throwing the trailer off balance.
