PATAS
Especially developped for the careful delimbing of larch, pine, spruce, pre-delimbing Douglas fir and eucalyptus, poplars or teak plantations
Simple facts and figures are giving proof of the company’s self-confidentially claimed quantum leap in the field of delimbing higher trees: For the time being, foresters and service providers were glad to finish four trees or maybe six per hour by piecework. Using the PATAS will enable them to do 30 up to 50 trees an hour (in european forests, in plantations it will be 80 – 100 trees an hour). While usually no one would take the effort to continue delimbing much higher than eight meters, the advaligno machine allows for a range between 12 and 15 meters with the easiest possible operation. When you see the machine at work, you immediately understand how this immense advantage in efficiency is achieved: the PATAS will go up the tree for a complete delimbing process in nearly incredible eight to ten seconds – and back down again!
The cutting head reaches the necessary speed via hydraulically driven rubber belts that guarantee minimum bark pressure and maximum grip. During the whole year, precisely designed blades separate all branches cleanly and safely from the tree. The entire system consists of two modules: a drive unit for the connection to standardized small tractors, as well as the already mentioned cutting unit, which then works on the tree. For sure we have secured our technology by patents.
Also usable as a small-sized Harvester
We are encouraged, that forestry experts indicated that our PATAS offers an additional benefit: You may use it as a small-sized harvester. Trees, intended for felling may be delimbed by our PATAS. That prevents you from the time-consuming, dangerous and cost-intensive delimbing after felling the tree. To gain that advantage it is irrelevant, whether you want to fell the tree next week or in 20 years – the lower 12-15 meters keep delimbed. That means, in most cases you can obstain from expense use of a harvester or the manual delimbing after felling – that saves you money and time.
