HEAVY DUTY shear

4500EFI shear is designed to be installed into 14-20 t. excavators. With the head you can use your excavator for cleaning up roadsides, fieldsides and other demanding energy wood locations. Large opening, compact structure and powerful shear makes this head efficient even in the most demanding locations.

POWERFUL SHEAR

Cuts with two blades. The angles of the blades sink into the wood with great power and presses the wood against the head's frame. Small trees are cut fast with smaller power. For larger trees the blades slow down, while the strength increases. You can cut up to  45 cm tree at once!

SIMPLE INSTALLATION 

EFI (electric free installation) heads operate without electricity. The head works on open/close lines. Assembly is easy and fast. Just attach the head to the excavators' quick coupler and attach two hoses. Recommended pressure and flow for the head are 200-250 bar and 100-120 l/min.

SAFE TREE HANDLING

The operating logic of the head is build around the hydraulic block. Once you press the head closed, the grapples first move towards closing. As the pressure increases, the cutting blades begin closing. When the tree has been cut, you press open-button. Blades open first completely, and after that the grapple jaws. If the head has been upgraded with collecting unit, collecting will take place automatically after the cut. The operating logic ensures safe handling of trees. Grapple jaws always have strong grip on the tree, which ensures that the tree won't fall down uncontrollably.
