Production of wood chips from logging residue under space-constrained conditions
Matevž Mihelič, Raffaele Spinelli, Anton Poje
Izvirni znanstveni članek
Oznake: forestry;biomass;logistics;mountain;harvesting;
A study was conducted on chip production from logging residue left after a cable yarder operation. The logistics were managed with tractor and trailer units (shuttles). The study specifically dealt with a very difficult case of space constrained operations, further expanding the knowledge about chip ...

ǂThe ǂeffect of feedstock, knife wear and work station on the exposure to noise and vibrations in wood chipping operations
Anton Poje, Raffaele Spinelli, Natascia Magagnotti, Matevž Mihelič
Izvirni znanstveni članek
Oznake: biomass;fuelwood;ergonomics;safety;biomasa;lesna goriva;sekalnik;tresenje;
Industrial chipping is becoming increasingly popular, as the result of a growing demand for woody biomass. Industrial chippers are large, powerful machines that generate much noise and vibration. This study explored some factors that may affect exposure to noise and vibration, namely: feedstock type ...

ǂA ǂlow-investment option for the integrated semi-mechanized harvesting of small-scale, short-rotation Poplar plantations
Raffaele Spinelli, Natascia Magagnotti, Carolina Lombardini, Matevž Mihelič
Izvirni znanstveni članek
Oznake: logging;felling;productivity;cost;effciency;investment;
In recent years, industrial roundwood production has enjoyed a steady success due to the development of a new bioeconomy and the rapid structural changes of the wood market. A very promising new solution for industrial fiber crops is the integrated production of logs and biomass in short rotation po ...

Fitocenološka združba kot kazalnik občutljivosti gozdnih tal za vožnjo gozdarske mehanizacije
Gašper Ogrin, Raffaele Spinelli, Natascia Magagnotti, Velid Halilović, Matevž Mihelič
Izvirni znanstveni članek
Oznake: gozdarstvo;zbijanje tal;gozdna tla;fitocenoza;globina kolesnic;
Z namenom ugotavljanja vpliva fitocenološke združbe na občutljivost gozdnih tal za vožnjo gozdarske mehanizacije smo v gozdovih GE Zaplana opravili 90 meritev profilov sekundarnih gozdnih prometnic. Vzorčenje je potekalo vzdolž linije, dolge 13,9 km. Povprečna globina kolesnic na profilih je znašala ...

Logging residue chipping options for short rotation poplar plantations
Raffaele Spinelli, Matevž Mihelič, Barnabáš Kováč, Patrik Heger, Natascia Magagnotti
Izvirni znanstveni članek
Oznake: gozdarstvo;učinkovitost;produktivnost;stroški;spravilo lesa;forestry;efficiency;productivity;cost;
Short rotation poplar plantations grow on flat and even terrain, and the interrow spacing is wide enough for easy machine access. If the terrain is firm enough, one may consider moving the classic roadside chipping operation directly into the field (i.e., terrain chipping), thus saving on wood extra ...

ǂThe ǂeffect of knife wear and sharpening mode on chipper productivity and delays
Matevž Mihelič, Dinko Vusić, Branko Ursić, Antonio Zadro, Raffaele Spinelli
Izvirni znanstveni članek
Oznake: suho brušenje;mokro brušenje;čas zamude;dry sharpening;wet sharpening;delay time;
The production of wood chips can be achieved using different types of wood chippers whose productivity can be influenced by many factors including proper knife management. Research was conducted to determine the productivity of the new Diamant chipper in chipping air-dried tops stacked at a roadside ...

ǂA ǂlong-term follow-up study of slash bundling in fast-growing Eucalypt plantations
Raffaele Spinelli, Natascia Magagnotti, Alberto Assirelli, João Pedro Martins, Matevž Mihelič
Izvirni znanstveni članek
Oznake: biomasa;produktivnost;donos;hitrorastoči gozdovi;harvesting;biomass;productivity;downtime;utilization;
The Authors conducted a long-term follow-up study of a John Deere 1490 forwarder-mounted bundler owned by a Portuguese company and used for bundling logging residues from fast-growing eucalypt plantations located in Portugal and Spain. The study spanned 7 years, from 2011 to 2016. During this time, ...

Evaluation of different modes for yarding windthrown timber with a double-hitch carriage
Raffaele Spinelli, Karl Stampfer, Natascia Magagnotti, Giulio Cosola, Fabio De Francesco, Gernot Erber, Matevž Mihelič
Izvirni znanstveni članek
Oznake: sečnja;strmi tereni;varstvo pri delu;učinkovitost;harvesting;logging;steep terrain;carriage;horizontal yarding;work safety;efficiency;
Yarding whole trees is the most efficient way of extracting timber in steep terrain and allows reaping the combined benefits of mechanization and biomass recovery. In downhill yarding, however, whole-tree extraction is associated with a greater risk of loosening rocks or debris by the incoming loads ...
