This Speedy De-limbing Tree Machine Could Revolutionize Forestry
Forestry experts in Germany are rethinking the way they de-limb trees in a faster, higher, safer, and more cost-effective and efficient way that could revolutionize the industry. German-based and family-run advaligno offers a system for the mechanical de-limbing of live trees to produce high-grade wood.
Dead or dying dry branches add to the fire risk and rob sunlight, water, and nutrients from the healthy parts of the tree. Plus, sick branches are a prime location for insects and diseases to enter and kill the tree, according to foresters. The debris that results from the trees’ de-limbing should also be removed from the ground to avoid further fire risk.
Before, de-limbing trees only rose to heights of about eight meters, which required tools and methods that involved complicated and strenuous manual work with large crews. Today, the advaligno PATAS machine, which is named after the fastest climbing monkeys, allows for a range between 12 and 15 meters with a seamless operation.
The advaligno PATAS machine is specifically developed for the cautious de-limbing of larch, pine, spruce, and the pre-de-limbing of Douglas fir, eucalyptus, poplars, and teak plantations.
Typically, foresters and service providers would expect to finish four to six trees per hour by piecework. However, using the advaligno PATAS will enable them to do 30 to 50 trees an hour (“in European forests, in plantations, it will be 80 – 100 trees an hour”). In just eight to ten seconds, the advaligno PATAS will go up the tree for a complete de-limbing process and easily return back to the ground.
According to advaligno, the cutting head reaches the proper speed via hydraulically driven rubber belts that guarantee minimum bark pressure and maximum grip. State-of-the-art blades precisely separate all branches cleanly and safely from the tree. The complete system is made up of two modules – a drive unit for the connection to standardized small tractors. This includes the aforementioned cutting unit, which then works on the tree.
With more than a 70 percent cost reduction, a substantial number of trees can be de-limbed when compared to before. In turn, forest owners will significantly increase the value and yield of their forestry by growing branch-free timber.
