TECHNOLOGY REVIEW – HARVESTERS
year’s examination of the industry’s cut-to-length (CTL) harvesting technology, International Forest Industries has also detected a shift back toward larger, more robust machines for tackling demanding clear cuts and testing conditions. At the very least, there is a
T
more widely represented range of intermediate machines that can be used in either small scale or thinning operations as easily as they can be applied to more robust applications with larger log diameters. Ponsse in particular has dedicated much of its research in recent years to varied harvesting requirements on difficult terrains. This is primarily down to more delicate peat environments, which are a major source of wood in Finland. As the manufacturer goes on to say, the key to limiting damage in such conditions is by cutting back on the ground pressure, primarily by distributing the weight over more wheels. Other manufactures, typically those outside Europe that are more familiar with North American markets, are producing new techniques and technologies for coping with rocky and steep
he importance of smaller diameter wood harvesting remains clear, but in this
gradient conditions. Also of note in this year’s review
is the progress of traditionally Tree-Length supplier, Tigercat, in snatching up CTL market share, particularly in Sweden, with its evolving range of CTL machines.
The Vimek 404T4 is one of the most efficient small scale harvesters on the market today, a standing it enjoys because of unique features like dual-steering function, low fuel consumption, low ground pressure, high capacity and an overall low up front cost for an economical and strong performance. The 404T4 is the fourth
generation of the 404 model. The latest evolution has seen major improvements with a stronger front axle that offers alternative machine width (1.8 m or 2.15 m), and the addition of a crane Mowi 2046 with a maximum reach of 4.6 m. The machine is also equipped with a unique Brake Link system from Vimek, a harvesting head Keto Forst Silver (cutting diameter of 300 mm) and computer Motomit IT. Of course the cabin can be set up with an air-conditioning system, which is just one example of the multiple accessories on offer. Vimek 404T4 can also be
delivered with different crane tip
attachments, such as clam shell bucket for ditch cleaning and/or a felling head for brush cleaning of, for example, road sides and under electric power lines. The Vimek 404 model harvester has been produced since 2006 and is today delivered into more than 10 different countries.
