Conversion of excavators for forestry work

Conversion of excavators for forestry work

Excavators continue to be one of the world’s most common base machines for harvester heads. In the course of years, Nisula harvester heads have been installed on 5-18 ton excavators worldwide. We can provide you with an equipment package that converts your excavator into a timber harvester. In addition to a harvester head, we provide a suitable control system and the control switches and the wire harness needed for the head. The new Nisula SB and XB extra boom lineups provide better reach and features for harvesting. Nisula’s distributor in your country will provide you with further information on the installation.

NISULA CONTROL SYSTEMS

Nisula NCU3 / NCU3i

Nisula NCU3 measuring device with a 5.4” screen is the result of four decades of experience in the industry. The new electronics generation has increased the computing capacity of the system; NCU3 controls the head precisely. The simple menu structure makes it easy for operators to find the settings they need.

The hydraulics control has been taken to a new level, allowing fast and accurate feed to the sawing window. Accuracy is excellent in all conditions. There is a separate fuse for the sensors to reduce the risk of damage to them. The NCU3i model is equipped with a larger 7” colour screen. The value scaling function improves work efficiency

Nisula NCU3X

NCU3X is equipped with a larger 12.1” touch screen. The X-model is equipped with value scaling function and data transfer facility. Thanks to the new electronics generation and increased computing capacity, value scaling is accurate. The new advanced algorithm also maximises the efficiency.
As the PC used for reading mapping software and for data transfer is a separate system, the embedded solution guarantees reliability. Possible Windows/PC problems do not stop harvesting operations. The operations do not depend on the PC’s computing capacity, either. Therefore forestry companies’ software may contain extensive maps and other heavy-duty properties.
