Crane operation at its easiest

For a harvester operator, an easily operated crane is important for ensuring a productive working day. With Komatsu Smart Crane, the crane – from the main boom all the way to the tip of the telescopic arm – is controlled with a single, smooth lever movement. The high precision and responsiveness of the crane contributes to a more relaxed way of working, meaning you as an operator can keep up a high and steady production while still feeling more refreshed at the end of the working day.
