HIGHLIGHTS

With the cutting blade attached small trees can be felled and bundled on the ground or felled and loaded directly on the trailer.

With the cutting blade detached and the tilt mechanically locked, the head can be used like a normal timber grapple to load energy wood or other timber grades

Nisula Energy Wood Heads

The series covers four different size categories for different customer needs. The E-series energy wood heads are easy to install in the place of a normal timber grapple. They do not require electricity or additional hydraulics.

All the structures are made of high strength steel. The structures are welded by using special filler metals designed for high strength steel. The shaft sleeves are made of tempered steel and the axles of surface hardened tempered steel.

Nisula 205E - Energy Wood Head For Heavy Duty Work

205e 2The renewed 205E is based on the popular 200E Energy Wood Head. The adjustable block makes it easy to adjust the tilt for various pressure levels. The colouring of the head is also new. With 250E you can equip e.g. a forwarder for energy wood harvesting easily without major installations or modifications. Just attach the head in the place of the normal grapple and the machine is ready to harvest energy wood. The spike-shaped grapple arms ensure that all the grabbed trees get cut by the blade and are not pulled out of the ground. When loading, the head efficiently grabs the wood bunches and the high pressing power ensures effortless handling of even big bunches. Thanks to the grapple design, the head does not easily grab dirt or stones, nor do branches get stuck in the grapple.

Nisula 285E has minor updates in the cylinders, and the colouring of the head is also new. 285E is an efficient and compact head for professional small wood harvesting: easy felling, bunching and loading. Depending on the base machine, the whole small wood harvesting process (standing tree to roadside) can be performed without changing the head. Thanks to its structure, the head grabs trees and bushes efficiently. The grapple arms, which are located near the scissor blades, ensure that the stems and even twigs are cut by the blades.

Nisula 285E+ is equipped with a special accumulating tilt system which improves the head's collecting capacity and the handling of the bundles.

Nisula NCU1 Control Unit For Accumulating Energy Wood Heads

F.A.Q'S

Energy Head

What additional hydraulics do I need?

These heads don't require any additional hydraulic features apart from model 285E and 285E+

Can I still use it to load wood?

They can be used as a grab by locking a pin and removing the blade, or used with the blade in situ but being careful!!

How do they fasten to the machine?

A 2 directional swing damper welded to the crane boom or quick hitch for a digger is recommended.
