It is a guide rather then a training manual, which briefly highlights key concepts that an arborist faces while learning the fundamentals of tree climbing. My intent was to draw from several arboriculture sources that illustrate key climbing skills. What inspired me to compile this guide was that I wanted to have all of my source materials in one place. I integrated some of the skill descriptions and pictures into the guide to further illustrate a particular concept. This guide covers safety, site inspection, gear, rope installation, working in the tree, cabling, and chainsaw maintenance. During my training here at the arboretum I have discovered how to make improvements to a specific technique or skill. I have incorporated some of my insights into the guide in order to aid the climber with their own climbing education. Helpful references have been included in the works cited section. These references range from books related to tying knots and advanced climbing techniques, to websites that list job openings in the tree care industry. I encourage you to explore these valuable resources and discover more about the arboriculture profession The compendium of skills should in no way be a primary source for climber education. In order to learn how to climb, a beginning climber should have hands on instruction with a qualified instructor. Climbing techniques should be critiqued and adjusted as the climber progresses as a professional. The guide will help the climber review their skills without describing all aspects of the training process. Finally, all information included in this guide is for the sole purpose of education in the field of arboriculture. The author is not responsible for the use/misuse of the materials detailed in this guide or any injury incurred as a result. Safe work practices begin with the individual who must remain ever vigilant not only themselves but for others working in the field. I would like to personally thank all the individuals who assisted me in the creation of this guide. Also, to the entire arboretum staff who have inspired me to become a better arborist with each passing day. Sincerely, Travis Barck – Arborist Intern 07’ 4 SAFETY TIPS Before a climber can make their accent into a tree safe work practices should be thoroughly reviewed. All gear should be inspected for defects and replaced if necessary. A climbing plan and site inspection will ensure that potential hazards are addressed and that the climber will understand the objectives of the job. The benchmark for safety standards that all climbers must be aware of is the ANSI Safety Requirements for arboricultural operations. ANSI = American National Standards Institute Officially entitled: ANSI Z133.1 Safety Requirements for Arboricultural Operations This reference sets the standard for the arboriculture community and is committed to safety in all aspects of the industry. Two words are mentioned in the text that the arborist needs to be aware of: Should and Shall Should implies that the safety measures listed are recommended to all parties involved. Shall dictates that all persons comply with the safety measures listed in accordance with state and federal occupational safety regulations. Figure 1 – Sherrill Figure 2 - Sherrill Figure 3 - Sherrill 5 Safety standards and best work practices are of utmost importance and should be followed in all aspects of job performance. Compliance, communication and team-oriented cooperation are the keys to creating a safe incident-free work environment. Safety is the responsibility of every employee from the senior foreman to the newest employee on the job. The Morris Arboretum requires all employees to perform professional work in an efficient manor, keeping safety first and maintaining a safe and incident free work environment. Gear inspection: All gear should be inspected before and after climbing. Climbing lines should be inspected for excessive wear or defects as listed below. Figure 1 - White, Kilmesova Inspect climbing saddles, lanyards, carabiners, and all other climbing equipment. If you have any questions/concerns about the safety of the equipment ask your supervisor. 6 There are many different types of tools and gear available to the arborist and the best way to ensure safety is to familiarize yourself with the gear being used. Personal Protective Equipment or PPE is a must and is a part of the ANSI safety standards for all arborists. This includes: Hearing Protection, Hard Hat and Safety Glasses. Other recommended gear includes work boots, gloves and clothing that can make working in the elements comfortable and safe. Site inspection Before mapping a climbing route a through site inspection will allow the climber to identify possible hazards. This is a safety must that should become a part of every climbers routine before the climbing line is installed. Here is an illustration of some potential hazards that every arborist should be aware of: Figure 2 - White, Kilmesove 7 SITE INSPECTION The illustration depicts hazards that arborists commonly encounter. A pre-climb inspection should start by identifying potential hazards. Some of the hazards include: Submerged or compromised roots from construction or grade changes Decay - Root, Trunk, Branch Crotches, Cavities Cavities or structural defects throughout the tree Mushroom growth Poisonous plants - (poison ivy, sumac) and growing in or around the tree Hanging limbs or "hangers" Wildlife (ex. squirrels or bee nests) Electrical Hazards - e.g. Power lines Storm damage or rain or ice covered branches Targets = Objects that should be avoided within the drop zone where damage is possible Prior site impact due to construction, pesticide application, poor drainage resulting in the sudden necrosis of leaders and/or decline of the tree Figure 2 - White, Kilmesova 8 ROPE TERMINOLOGY AND ESSENTIALS Understanding what parts of the climbing rope an instructor is referring to make instruction easier for both parties. Confusing the running end with the working end can mean all the difference when tying in to one end verses the other. These two illustrations will help the climber to understand the rope parts and their application while climbing. Figure 3 -White, Kilmesova 9 Beginner knots that every tree Climber should know: Before a beginning climber ever attempts to tie a knot they should be aware of a simple concept known as Tie, Dress, and Set or (TDS). Although the concept is simple not all knots are easy to tie and require patience and practice in order to master. One quote sums up knot tying process: "A knot is never nearly right; it is either exactly right or it is hopelessly wrong, one or the other; there is nothing in between." Clifford Ashley --Exert from the Climber's Companion The Bowline knot is commonly used to attach climbing lines to saddles and carabiners. Some climbers use additional safety measures such

  • Portable Hammock Stand Design and Business Model Development
    PORTABLE HAMMOCK STAND DESIGN AND BUSINESS MODEL DEVELOPMENT Evan Keith Industrial Technology Orfalea College of Business California Polytechnic State University March 14th, 2013 ABSTRACT Currently hammocks are thought of as stationary relaxation devices that use tress as support structures. The industry mainly focuses on hammock innovation over the way in which the hammock is actually hung. Having been around for thousands of years, reinventing the idea of the hammock is not something that is occurring or has been thought of. This senior project proposes the idea of a portable or more adaptable hammock stand. It takes the idea of hammocks as stationary devices to them being something that can be taken almost anywhere. Shifting how hammocks are thought of and exposing the potential they posses by introducing an innovative hammock stand. The report discusses the design and use of a light weight easy to use hammock stand. Through market research and product development, a portable hammock stand is presented with a rough business plan as to how to make a sustainable business model around the product. ii ACKNOWLEDGMENTS iii TABLE OF CONTENTS Abstract…………………………………………………………………………………………ii Acknowledgments ……………………………………………………………………………..iii List of Tables……………………………………………………………………………………v List of Figures…………………………………………………………………………………...v Section Page I…………………………………………………………………………………………1 II………………………………………………………………………………………...7 III……………………………………………………………………………………….17 IV……………………………………………………………………………………….32 V………………………………………………………………………………………...37

    AN ABSTRACT OF THE THESIS OF Joel Hartter for the degree of Master of Science in Forest Engineering presented on April 21, 2004. Title: Investigation of Synthetic Rope End Connections and Terminations in Timber Harvesting Applications Abstract approved: John J. Garland Steel wire rope is the accepted standard in logging. It is strong, durable, stiff, and dependable in the logger’s arsenal. However, steel wire rope has several disadvantages: its strength to weight ratio is low; it is difficult and time-consuming to splice; and used wire ropes contain jaggers. Ultra-high molecular weight polyethylene (UHMW-PE) braided rope has potential to replace steel wire rope. The offshore mooring and shipping industries have appreciated it for years. Characteristics such as a specific gravity less than one (it floats!), high flexibility, low stretch, and ease of splicing make the synthetic rope useful. At equivalent diameters, synthetic rope has an equal or greater breaking strength to that of steel wire rope, but at 1/7 the weight. This thesis is an investigation of the end connectors for the unique physical, mechanical, and thermal properties of UHMW-PE 12-strand braided rope that make this technology of interest in logging applications. This studied focused on three diameter classes of the synthetic rope that are common to logging operations: 3/8”, 9/16”, and 5/8”. Within each diameter class there were five different spools representing separate production runs. A randomized complete block design was used with each diameter class and the corresponding five spools a separate population. Following the laboratory tests, the breaking strengths were compared to the buried eye splice.

  • 2006 Annual Bibliography College of Forestry and the Oregon Forest Research Laboratory from the Director Contents
    2006 Annual Bibliography College of Forestry and the Oregon Forest Research Laboratory From the Director Contents regon has a strong reputation as a global leader in forestry and forest products, and it Ocontinues to be the nation’s leader in softwood lumber production. In addition to providing sustainable, economic benefi ts to Oregonians, the forestlands promote environmental and water quality, provide fi sh and wildlife habitats, meet social and recreational needs for the people, and are vital to climate moderation. Providing the research and management expertise to optimize the multiple, and sometimes competing, values of our forests and enhance the effectiveness of forest sector industries is the task of the Oregon Forest Research Laboratory. Our scientists collaborate with peers in other organizations and other disciplines to discover ‘new’ knowledge, as well as to challenge or expand on current knowledge related to the processes, interactions, and impacts of forestry, natural resources, and ecosystem activities. The knowledge generated from these efforts is routinely made available via a broad range of publications. This annotated bibliography is intended to recap the scientifi c fi ndings published between January 1 and December 30, 2006. The information is arranged in fi ve program areas, but I believe you’ll fi nd the richness and depth of the research being conducted by our scientists goes well beyond these thematic terms. This booklet is a strong testament to their productivity, and to the state, federal and private organizations that help fund our continuing quest for the knowledge that will help the natural resources, ecosystems, and citizens of Oregon, the nation, and the world.
