HYPRO FG45 Felling Grapple/Energy Felling Grapple

The HYPRO FG45 felling grapple can in principle be mounted on all cranes with rotators, for example on forest trailers, forwarders and excavators. It is used to fell, cut, load and unload trees and brushwood in forests, along roads, powerline corridors, in park and urban environments, but naturally also together with HYPRO’s tractor processors.

FG45 is supplied as standard in an energy grapple model. It is then equipped with open grapple fingers (brush/energy wood grapple), 10cc saw motor and 59 centimetre saw bar. It can also be equipped with a special, 54 centimetre saw bar (energy bar) to enable cutting of everything from shrubbery all the way up to large, 45 centimetre cuts. The bar’s design means that the chain is also tensioned along the long sides, thereby providing considerably better stability when cutting several stems simultaneously such as with brushwood or shrubs. Using an energy saw bar for this type of use considerably reduces chain jumps/throws. For hydraulic systems that do not achieve more than 60 l/min oil flow, the felling grapple can also be equipped with a smaller (5cc) cutting motor to retain high chain speed and effective cutting capacity.

The FG45 has a tilt function that automatically tilts the grapple into its felling position when it is fully open. If return is required, this is achieved by briefly activating the cutting saw, causing the grapple to return to its horizontal working position.

The crane’s valve needs to be equipped with a free section or with an additional valve for activation of the saw motor. This must be a motor slide model (open centre), which is then open directly to the tank in its neutral position, alternatively the return hose and the motor drainage hoses are installed directly to the tank.

The versatility of the felling grapple and its hydraulic tilting joint make it possible to easily access tree trunks at the right felling angle. This makes the felling operation highly rational and simple. Its low weight also makes it ideal for use on cranes with a very long reach without adversely affecting stability or lifting capacity.
