a set-up using a high stump for yarding operation

rv0D AND AGRICULTURE ORGANIZATION OF THE UNITED …

Tailholds and intermediate supports for the yarding lines may use trees as anchors and support, but the yarder guylines should use stumps to avoid the possibility of a tree falling on workers at the landing site during the operation. If a tree must be used, tie it back to prevent it from falling.LIST OF CONTENTS Page No, INTRODUCTION 1 CABLE LOGGING SYSTEMS 1 2.1 Independent Bunching Winches 2 2.2 Machine-mounted Winches 5 2.3 Yarders 9 2.3.1 Ground Lead 18 2.3.2 High Lead 19 2.3.3 Snubbing 20 2.3.4 Tyler System 21 2.3.5 Endless Line System 22 2.3.6 Endless Tyler 22 2.3.7 North Bend 23 2.3.8 Slackline 24 2.3.9 Running Skyline 25 2.3.10 Continuous Mainline 26 2.4 Yarding …- Combined use of crawler and wheeled skidders .

Also called a "hooker" - a man in charge of the yarding crew and releasing chokers at the landing. Hoot owlThis thesis reports a study of production and ergonomic factors in a grapple yarding operation, observed during at MacMillan Bloedel Ltd's Shawnigan Logging Division, near Duncan, British Columbia. Optimizing safety, health and performance requires detailed evaluation of factors affecting man-machine relationships during actual industrial operations. In the case of grapple yarding, these.

Gravity systems require about 30% sideslope for the carriage to return to the hookup site. Very steep or broken terrain (> 70%) can increase the amount of breakage during fall-ing and yarding and decrease the mobility of on-the-ground workers.

Performance Analysis of Log Extraction by a Small Shovel

Stump Jumper: A heavy plate underneath a skidder that protects the back housing from contact with high stumps. Stump Pull: Slivers of wood remaining attached to the stump after a tree is felled; the slivers are considered as having been pulled from the butt of the log. Stumpwood: Wood cut into short lengths and piled near the stumps. Stumpwood ...A swing yarder is a mobile piece of heavy duty forestry equipment used for pulling logs from the woods to a logging road with cables.The swing yarder is also known as a grapple yarder.. In any logging operation, it is necessary to transport the harvested tree from the stump to a landing for transport to market (usually on a truck). If the ground is relatively flat it may be possible to ...However, the use of the TL-C method for log hauling activities remains limited since this method requires not only a high skill level, but also an inherently high level of investment [26]. Thus, cable yarding systems have rarely been implemented on steep slopes and remote areas due to operation costs.

The skyline yarding system was the first to use a remote control carriage. American made standing skyline cranes have been using radio controlled carriages since (Pearce and Stenzel ). As a result of pressures to protect the environment, it was recognized about 25 years ago that a method of yarding that.
