Komatsu Forest launches a new harvester head for demanding felling operations

Jun 14, 2015. /Lesprom Network/. Komatsu Forest launches the S172 harvester head, the largest two-wheel fed head in the S-series so far from the company. The harvester head is highly efficient and reliable and built for demanding felling operations, as the company says in the press release received by Lesprom Network.

The Komatsu S172 is designed for its largest harvester, the Komatsu 951, and is the heaviest head that can be delivered together with a 10-metre crane. The head weight starts at 1675 kg. The Komatsu S172 is an extremely effective and reliable head, designed for harvesting large diameter trees. It offers effective delimbing with three hydraulically controlled delimbing knives and a fourth, moving vertical knife. The head features Flex Friction Control, which means that the stem's position in the feed path is regulated by a sensor in the vertical knife. The result is low friction without sacrificing delimbing quality.

The feed system is based on two powerful feed rollers that can handle truly large trees. The head provides high feed force thanks to the special motor design. When great force is required to feed a tree the motors slow down in order to deliver more power. Likewise, if less force is required to feed a tree the motors speed up – everything to maximise productivity.

The Komatsu S172 will go into production in June 2015.
