Euca seems to hold all the right cards!
LOGSET HAS launched a new harvester head, the TH65 Euca and, as its name implies, it’s designed for harvesting and debarking mediumsized eucalyptus trees. It’s the third harvester head designed for harvesting eucalyptus in the TH-series.
The TH65 Euca’s dimensions are similar to the Logset harvester head TH65. It weighs 1,100kg and can be mounted on a Logset 8H GT harvester or on track-based machines weighing 20-35 tons. “The Logset harvester heads have basically all the qualities needed for harvesting and debarking eucalyptus,” said Jonas Hedstrom, development manager.
“Designing special harvester heads for eucalyptus was not a big step for us. In the TH65 Euca, the feeding wheels and delimbing knives are equipped with parallel feed, which means that the eucalyptus stems are well centred in the harvester head. The stem maintains this position even when moving through the harvester during debarking,” he explained.
“The TH65 Euca was developed in tight collaboration with our dealers and end users to ensure that the product fulfills and exceeds the demands of this specialized field of forestry,” he said.
Logset has been manufacturing harvesting heads for eucalyptus for more than 20 years, so eucalyptus debarking is nothing new or unknown for the company.
“What’s new is that we have stepped down in size to the so-called middle sized segment. The reason is that this segment is the fastest growing today due to increased investments in pulp mills using eucalyptus as raw material especially in South America.
“The process for developing the product has been about two years including design and field tests. In the project team are several members with over 10 years of hands-on experience from eucalyptus harvesting.
“Jonas said that during the development process, one of the most important steps was producing an optimal debarking result during the first feeding. Another important quality was to make sure that the harvester head is kept clean of bark, so the work is not interrupted due to cleaning. “The demand for a medium-sized harvester head has grown among our customers who work with eucalyptus. Thanks to the TH65 Euca, I’m glad to say that we can now respond to this demand,” said vicepresident of sales Pascal Rety.
Logset has another major workhorse in the ranks with the TH85, the second largest head in Logset´s TH series. Together with the Logset 12H GTE Hybrid harvester it takes productivity to a level never seen before.
The head is designed for felling, feeding and cross cutting trees from 80cm down to 4cm diameter. Its three feeding wheels and four hydraulic motors provide an impressive feeding force, even in the most difficult trees. Its total weight of 2100kg ensure a reliable structure in terms of chassis, knifes, pivots and so more. The saw unit is available with both 0,404” or ¾” pitch saw chains and up to 1 metre saw bar.
The TH85 has all the elements needed for great cut on timber with performance and efficiency.
The Logset TH series is provided as standard with Logset TOC-MD measuring and control device. Ceaseless adjustments are available from the control such as proportional knife control, automatic cross cutting, feeding speed control. The TOC-MD provides seamless cooperation with the head to guarantee high productivity.
This head, too, was developed as a response to customer needs and demands. It can be mounted on the world’s biggest harvester - the Logset 12H GTE Hybrid harvester - or on track based machines weighing 25-30 tons. The ease of daily maintenance has been the key criterion during the development process. “We held on to our philosophy with the earlier heads — less is more. This head has less components and more steel. The point is to achieve minimum downtime and maximum productivity,” said Jonas, who had been in charge of the development process of the TH85.
“In the beginning of April, we sent a Logset 12H GTE Hybrid harvester with a TH85 harvester head to Australia. This combination is a wheel based machine the market hasn’t seen before. Logset has 25 years of experience in making harvesters and harvester heads. The THseries has gone through a 10-year period of technical evolution, so we felt confident about introducing the product on a new market,” said Pascal.
