Cable logging opportunities for firewood in Calabrian forests

Giuseppe Zimbalatti, Andrea R. Proto
2009 Biosystems Engineering  
Cable cranes are among the most important means of yarding and transporting timber and their use in the mountainous regions of Europe is becoming more widespread. In contrast, the use of this kind of machinery in Southern Italy remains limited, particularly in forests for firewood production, where cable cranes are practically not applied. Forests in Southern Italy are mainly located in steeply sloping mountainous areas where ground based wood extraction are still the most common harvesting

The productivity of different cable cranes was assessed to verify if the use of these machines should be efficiently recommended under the forest conditions in Southern Italy. The cable cranes tested have been the Greifenberg TG 700, Koller K300 and Greifenberg VSG 2000; the tests were carried out in areas of Calabria (Southern Italy) different for site features, forest management parameters and forestry. The time motion study carried out showed that the productivity of cable crane tested was satisfactory although there is a number of organizational aspects that could be improved in order to better exploit its potential.

Biomass Production in Agroforestry Systems: V.E.Ri.For Project

Andrea R. Proto, Giuseppe Zimbalatti, Lorenzo Abenavoli, Bruno Bernardi, Soraya Benalia
2014 Advanced Engineering Forum  
The biomass for energy purposes, coming from agroforestry systems and timber industry, can provide various environmental and socio-economic benefits. Among all renewable energy sources, agroforestry biomass represents both an important alternative source to fossil fuels and an opportunity for the socio-economic development of various marginal areas in Italy. In particular, agroforestry is a collective name of land use systems in which woody perennials are grown in association with herbaceous

Estimating availability of biomass resources is important to assess bioenergy production potential and so bioenergy contribution to annual energy demand. In the supply of biomass to energy use, the planning of operations is the basis for sustainable development of agroforest system. Most existing forest practice rules and recommendations did not anticipate this increased extraction of woody biomass and offer no specific guidance on how much removal is healthy for ecosystems. Intensification of biomass utilization, particularly for energy and fuel needs, presents a range of potential environmental risks. Therefore, the research focuses on development of guidelines for increasing a sustainable biomass supply chain at local scale, in order to facilitate energy planning that considers the local system carrying capacity and the potential of substitution of fossil fuels.

2010 Journal of Agricultural Engineering  
In Italy, the woodworking industry presents many issues in terms of occupational health and safety. This study on exposure to wood dust could contribute to the realization of a prevention model in order to limit exposure to carcinogenic agents to the worker. The sampling methodology illustrated the analysis of dust emissions from the woodworking machinery in operation throughout the various processing cycles. The quantitative and qualitative assessment of exposure was performed using two

The qualitative research of wood dust was performed using an advanced laser air particle counter. This allowed the number of particles present to be counted in real time. The results obtained allowed for an accurate assessment of the quality of the dust emitted inside the workplace during the various processing phases. The study highlighted the distribution of air particles within the different size classes, the exact number of both thin and ultra-thin dusts, and confirmed the high concentration of thin dust particles which can be very harmful to humans.

Comparative Evaluation of Inspection Techniques for Decay Detection in Urban Trees

Salvatore F. Papandrea, Andrea R. Proto, Maria F. Cataldo, Giuseppe Zimbalatti
2020 Environmental Sciences Proceedings  
Green areas in cities are acquiring an increasingly important role in urban architecture. However, a crucial problem associated with urban trees is the need to know and evaluate the health of plants in order to ensure the safety and security of citizens. One important process consists of the technical assessment of the conditions of standing trees, in order to prevent their falling due to strength failure or damage caused by internal decay. In recent years, investigations with non-destructive

This study reports the results of an inspection protocol that combines single-path stress wave timer and micro-drilling resistance to detect internal defects on Melia trees (Melia azedarach L.) located in the city of Reggio Calabria, Southern Italy.

2017 Annals of Forest Research  
S., 2017. Determination of forest road surface roughness by Kinect depth imaging. Ann. For. Res. 60(2): 217-226. Abstract. Roughness is a dynamic property of the gravel road surface that affects safety, ride comfort as well as vehicle tyre life and maintenance costs. A rapid survey of gravel road condition is fundamental for an effective maintenance planning and definition of the intervention priorities. Different non-contact techniques such as laser scanning, ultrasonic sensors and

The application of Microsoft Kinect™ depth camera is proposed and discussed here for collection of 3D data sets from gravel roads, to be implemented in order to allow quantification of surface roughness. The objectives are to: i) verify the applicability of the Kinect sensor for characterization of different forest roads, ii) identify the appropriateness and potential of different roughness parameters and iii) analyse the correlation with vibrations recoded by 3-axis accelerometers installed on different vehicles. The test took advantage of the implementation of the Kinect depth camera for surface roughness determination of 4 different forest gravel roads and one well-maintained asphalt road as reference. Different vehicles (mountain bike, off-road motorcycle, ATV vehicle, 4WD car and compact crossover) were included in the experiment in order to verify the vibration intensity when travelling on different road surface conditions. Correlations between the extracted roughness parameters and vibration levels of the tested vehicles were then verified. Coefficients of determination of between 0.76 and 0.97 were detected between average surface roughness and standard deviation of relative accelerations, with higher values in the case of lighter vehicles.

Technology application in post-harvest operations, has certainly contributed to make faster and less tiring all processing tasks. The main problem related to the mechanization of Tropea red onion post-harvest operations lies in the removal of the various layers of the external tunic, making it impossible for optical or electronic grader to achieve this task in a satisfactory way since the sensors are not able yet to separate the "bulb" from its involucre. In this context, the current study aims to assess the productivity of three different machines used for round Tropea red onion grading, and determine their work efficiency. The carried out analysis highlighted the ability of the studied machines to ensure a high work capacity, while maintaining a high level of precision during calibration process. Such precision allows to decrease laborer employment and increase processing chain speed, rising as well the annual use of the machines, allowing consequently processing cost savings. For a more profitable employment of such graders, it is, however, necessary from one hand, to properly form the technicians responsible of processing plants management, and from the other hand, to be able to take advantage of a technical assistance network, able to serve users in a short time.

Tensile Force Monitoring on Large Winch-Assist Forwarders Operating in British Columbia

Omar Mologni, Peter Dyson, Dzhamal Amishev, Andrea Rosario Proto, Giuseppe Zimbalatti, Raffaele Cavalli, Stefano Grigolato
2018 Croatian Journal of Forest Engineering  
The forest industry around the world is facing common challenges in accessing wood fiber on steep terrain. Fully mechanized harvesting systems based on specialized machines, such as winch-assist forwarders, have been specifically developed for improving the harvesting performances in steep grounds. While the mechanization process is recognized as a safety benefit, the use of cables for supporting the machine traction needs a proper investigation. Only a few studies have analyzed the cable

Consequently, a preliminary study focused on tensile force analysis of large winch-assist forwarders was conducted in three sites in the interior of British Columbia during the fall of 2017. The results report that in 86% of the cycles, the maximum working load of the cable was less than one-third of the minimum breaking load. The tensile force analysis showed an expected pattern of minimum tensile forces while the forwarders were traveling or unloading on the road site and high tensile forces when operating on steep trails, loading or traveling. Further analysis found that the maximum cycle tensile forces occurred most frequently when the machines were moving uphill, independently of whether they were empty or loaded. While the forwarders were operating on the trails, slope, travel direction, and distance of the machines from the anchor resulted statistically significant and able to account for 49% of tensile force variability. However, in the same conditions, the operator settings accounted for 77% of the tensile force variability, suggesting the human factor as the main variable in cable tensile force behavior during winch-assist operations.

Pelletization of Compost from Different Mixtures with the Addition of Exhausted Extinguishing Powders

Salvatore F. Papandrea, Maria F. Cataldo, Adriano Palma, Francesco Gallucci, Giuseppe Zimbalatti, Andrea Rosario Proto
2021 Agronomy  
Today, in Europe, there is still no industrial process to favor the distribution of exhausted extinguishing powders (EEP). Extinguishing powders (EP) are the most common extinguishing agents and are composed of very fine particles (90% is less than 0.250 mm, with at least 40% less than 0.040 mm). Illegal processes of disposal or reuse of EEP are currently taking place throughout Europe. In fact, often maintenance companies illegally dispose of and/or reuse spent extinguishing powders with

The demand for fertilizers is increasing; phosphorus is a key raw material, and a possible solution could be mixing it with compost and other organic biomass and agricultural residues. In general, both compost and EEP powder have a low density and can take up a great deal of storage volume, so thickening this compost would help reduce the required storage capacity. Furthermore, a danger represented by the handling of compost and EEP is the dispersion of dust that can potentially carry pathogens and toxic organic substances which, if inhaled, could cause respiratory problems during distribution and handling. The aim of this study was to produce compost pellets using exhausted EP in different formulations and to observe the quality of different compost pellet products with respect to different factors affecting handling, storage, and distribution. For the first time, the pelletizing of EEP with compost was performed successfully using five different blends, each with different properties. The results showed that qualitative variables could be controlled to optimize production efficiency and improve the quality of the finished product depending on the type of distribution, handling, and storage. The five compost mixes could be applied in different agricultural crops as fertilizer. Furthermore, this use of exhausted EP allows for positive ecological and economic effects, avoiding the disposal costs required by specializ [...]

Introduction. Weed control is one of the most important issues in the maintenance sectors of both agriculture and green areas. Small tools are employed for controlling grass and other growths on steep verges and river banks. This leads the operators being exposed to many risks among which vibration is one. The purpose of this study is to measure and evaluate hand-arm vibration and to verify the daily exposure to which workers are often subjected while weeding. Materials and method. Two cutting

The vibration total value was expressed as the root-mean-square (rms) of three component values according to the axes X, Y and Z. The signal was frequency weighted using the weighting curve Wh, as described in the ISO 5349-1 (2001) standard. In addition, the daily vibration exposure was calculated and compared with the thresholds set by EU Directive 2002/44/EC (2005. Results. The obtained results showed that the exposure action value (EAV) of 2.5 ms -2 was exceeded while using both cutting heads. The exposure limit value (ELV) using the brush knife also exceeded 5 ms -2 . Conclusions. The results highlighted important aspects in terms of exposure values that should be considered with the view of preventing the risk of Hand-Arm Vibration Syndrome (HAVS) to which the operators who frequently use these tools are exposed. Specific measures should therefore be taken to protect the exposed workers.
