Previous studies on log extraction, however, have focused on cable yarding operations with the goal of improving productivity on steep slopes and inaccessible sites, leaving small-shovel operations relatively unexamined. Therefore, the main objectives were to determine small-shovel extraction productivity and costs and to evaluate the impact of related variables on productivity. In addition, we developed a model to estimate productivity under various site conditions. The study took place in 30 case study areas; each area has trees with stems at a diameter at breast height ranging from 18 to 32 cm and a steep slope (greater than 15%). The areas ranged from 241 to 1129 trees per hectare, with conifer, deciduous, and mixed stands. -

Cable Yarding in North America and New Zealand: a Review of Developments and Practices
Subject review Cable Yarding in North America and New Zealand: A Review of Developments and Practices Rien Visser, Hunter Harrill Abstract Cable yarders have been an integral part of harvesting timber on steep terrain for over 150 years. They have developed from basic labour intensive steam powered winch operations to sophisti- cated and automated mechanised systems. While European yarder development has focused on relatively small but highly mobile machines operating with standing skyline configurations, the North American and Southern Hemisphere developments have tended towards larger, taller and more powerful machines capable of higher daily production. Two dominant North American brands, Madill and Thunderbird, produced over 3000 yarders and many of their machines continue to work today. Often working with 4 or 5 drums, they were able to develop and utilise an expansive range of rigging configurations to suit different extraction needs. Modern developments continue to focus on increasing production capability and cost-effective- ness suited to clear-cut plantation forestry. With safety becoming more paramount in terms of a licence to operate, a strong preference is given to fully mechanised systems. By definition, these are yarders with rigging systems that support grapple carriages, extracting timber that has been mechanically felled on steep slopes. While mechanical grapple carriages have long been combined with swing yarder systems, the further development of a motorised grapple carriage allows tower yarders to operate without choker-setters. Ergonomic improvements for the operator, long established in European machinery, are being integrated including cab design with greatly improved visibility and partially automated electric over hydraulic control systems. Logic would suggest that, over time, yarder developments will combine the strength and robustness of North American design and the finesse and automation of European design. -

A Comparative Analysis of Two Cable Yarder Technologies Performing Thinning Operations on a 33 Year Old Pine Plantation: a Potential Source of Wood for Energy

The main purpose of this study was to provide a comparative analysis of two cable yarder technologies (Maxwald, mobile pulley carriage and Savall, semi-automatic carriage), in terms of fuelwood production and cost, from the first thinning of a 33 year old plantation in slope areas of these plantations. The results showed that fuelwood production was cost-effective in both systems (Savall by 15.1 and Maxwald by 3 14.8 ¿ m− ), although the productivity of the Savall system was higher than the Maxwald system 3 1 (6.1 vs. 5.7 m h− ). The respect amounts of productivity have the potential to increase by 27% for the Savall yarder and 25% for the Maxwald yarder upon condition that the delay times are reduced to minimum level by proper training of workers, by a better organization, and planning of operations. -
Engineering Safety Solutions
25 October 2017 ENGINEERING SAFETY SOLUTIONS Reducing the risk of falling from a Madill 124 swing yarder In a perfect world we strive to ELIMINATE risks to health and safety. As we know this is not always possible—either the tools or technology doesn’t exist or it will be financially unviable. So we are then required to take a closer look at how we could MINIMISE the risk. Options may include : • Substituting (totally or partially) the hazard that creates the risk with something of lesser risk, an example of this would be replacing manual felling with mechanized felling where possi- ble. • Isolating the hazard to prevent contact, an example of this would be temporary traffic con- trol when felling within two tree lengths of a road. • Implementing engineering controls, an example of this would be a cut-out or disable switch. These three types of controls are far more reliable than the next layer of controls…...that is rules and procedures, followed by the use of personal protective equipment. This layer of controls is prone to human failure. Engineering controls or engineering safety solutions is the subject of this case study. When working around forestry machines, one of our greatest risks is falling from heights. While working with haulers, some of the routine activities that is crucial to machine operation need to be done at an elevated position, sometimes as high as 14m from the ground. Although fall arrest harnesses are provided for this work, there is some doubt that they are used all the time. People have reported not using the harness because it’s difficult to fit it correctly, it takes time to fit, there is not enough attachment points on the machines, and that they “feel safe” going up the gantry ladder without a harness. -
Implications of Selective Harvesting of Natural Forests for Forest Product Recovery and Forest Carbon Emissions: Cases from Tarai Nepal and Queensland Australia
Article Implications of Selective Harvesting of Natural Forests for Forest Product Recovery and Forest Carbon Emissions: Cases from Tarai Nepal and Queensland Australia Bishnu Hari Poudyal, Tek Narayan Maraseni * and Geoff Cockfield Centre for Sustainable Agricultural Systems, University of Southern Queensland, Queensland 4350, Australia * Correspondence: [email protected] Received: 5 July 2019; Accepted: 13 August 2019; Published: 15 August 2019 Abstract: Selective logging is one of the main natural forest harvesting approaches worldwide and contributes nearly 15% of global timber needs. However, there are increasing concerns that ongoing selective logging practices have led to decreased forest product supply, increased forest degradation, and contributed to forest based carbon emissions. Taking cases of natural forest harvesting practices from the Tarai region of Nepal and Queensland Australia, this study assesses forest product recovery and associated carbon emissions along the timber production chain. Field measurements and product flow analysis of 127 commercially harvested trees up to the exit gate of sawmills and interaction with sawmill owners and forest managers reveal that: (1) Queensland selective logging has less volume recovery (52.8%) compared to Nepal (94.5%) leaving significant utilizable volume in the forest, (2) Stump volume represents 5.5% of total timber volume in Nepal and 3.9% in Queensland with an average stump height of 43.3 cm and 40.1 cm in Nepal and Queensland respectively, (3) Average sawn timber output from the harvested logs is 36.3% in Queensland against 3 3 61% in Nepal, (4) Nepal and Queensland leave 0.186 Mg C m− and 0.718 Mg C m− on the forest floor respectively, (5) Each harvested tree damages an average of five plant species in Nepal and four in Queensland predominantly seedlings in both sites, and (6) Overall logging related total emissions in 3 3 Queensland are more than double (1.099 Mg C m− ) those in Nepal (0.488 Mg C m− ). -

Forestry Department of The University of British Columbia Vancouver, Canada April 29/1996 Date DE-6 (2/88) Abstract Public pressure to end clearcut logging, and changing forest management needs have increased opportunities for partial cutting in British Columbia's second-growth coastal forests. Production economics and engineering design of cable harvesting systems for partial cutting in second-growth forests of British Columbia (BC) are largely unknown. Scientific research and working experience in partial cutting forest harvesting operations in coastal areas of the Pacific Northwest of North America is from the United States or from selection harvesting of old growth forests in coastal BC prior to 1935.
