Performance Analysis of Log Extraction by a Small Shovel Operation in Steep Forests of South Korea

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. -

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. -
