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. -
Forestry Materials Forest Types and Treatments
-- - Forestry Materials Forest Types and Treatments mericans are looking to their forests today for more benefits than r ·~~.'~;:_~B~:;. A ever before-recreation, watershed protection, wildlife, timber, "'--;':r: .";'C: wilderness. Foresters are often able to enhance production of these bene- fits. This book features forestry techniques that are helping to achieve .,;~~.~...t& the American dream for the forest. , ~- ,.- The story is for landolVners, which means it is for everyone. Millions . .~: of Americans own individual tracts of woodland, many have shares in companies that manage forests, and all OWII the public lands managed by government agencies. The forestry profession exists to help all these landowners obtain the benefits they want from forests; but forests have limits. Like all living things, trees are restricted in what they can do and where they can exist. A tree that needs well-drained soil cannot thrive in a marsh. If seeds re- quire bare soil for germination, no amount of urging will get a seedling established on a pile of leaves. The fOllOwing pages describe th.: ways in which stands of trees can be grown under commonly Occllrring forest conditions ill the United States. Originating, growing, and tending stands of trees is called silvicllllllr~ \ I, 'R"7'" -, l'l;l.f\ .. (silva is the Latin word for forest). Without exaggeration, silviculture is the heartbeat of forestry. It is essential when humans wish to manage the forests-to accelerate the production or wildlife, timber, forage, or to in- / crease recreation and watershed values. Of course, some benerits- t • wilderness, a prime example-require that trees be left alone to pursue their' OWII destiny. -

Productivity Analysis of Fully Mechanised Cable Logging Operations in New Zealand
Productivity analysis of fully mechanised cable logging operations in New Zealand Prepared by: Luke Holmes, Final year Forest Engineering Student Supported by: Hunter Harrill, Research Assistant Supervised by: Rien Visser, Associate Professor Sponsored by: Rayonier I Matariki Forests 2017 School of Forestry, University of Canterbury L Holmes NZ Cable Harvesting Productivity 2017 Executive summary Modern day production requirements are continually increasing for logging crews throughout New Zealand. Growth in mechanisation, driven by the demand for a safer work place, requires large capital investments, and thus the demand for higher production to justify the increased cost. This analysis investigates fully mechanised extraction systems currently operating in the country and compares how the next generation of swing yarders may increase operational efficiently and productivity. Elemental time studies were used to quantify cycle time and calculate productivity for the purpose of comparing operations. Four elemental time studies were completed for cable yarder operations with over 200 cycles being recorded for each machine. These were conducted by Luke Holmes and Hunter Harrill during the first half of 2017. The focus was on the two new T-Mar ‘Log Champ’ swing yarders that have recently been imported to NZ (both 650 and 550 models) and an older style Madill 124 swing yarder which is a commonly found machine among NZ forests. These machines were all operating a mechanical grapple with a mobile tail hold. The studies also included one tower yarder operation which was using a Bellis BE 60 LT track based yarder This crew were using an innovative standing skyline system, operating the Block in the Bight rigging configuration, but replaced the chokers with a Helihawk grapple adapted for use on a cable logging system. -

Factors Affecting the Cost of Tractor Logging in the California Pine Region
UNIVERSITY OF CALIFORNIA COLLEGE OF AGRICULTURE AGRICULTURAL EXPERIMENT STATION BERKELEY, CALIFORNIA FACTORS AFFECTING THE COST OF TRACTOR LOGGING IN THE CALIFORNIA PINE REGION M. E. KRUEGER BULLETIN 474 AUGUST, 1929 UNIVERSITY OF CALIFORNIA PRINTING OFFICE BERKELEY, CALIFORNIA 1929 FACTORS AFFECTING THE COST OF TRACTOR LOGGING IN THE CALIFORNIA PINE REGION M. E. KRUEGERi The past five years have seen a very rapid expansion in the use of tractors for logging in the pine region of California. In 1923, when a previous bulletin 2 of this series was published, steam donkey yard- ing, with which that study treated, was the prevailing method of yarding. During the season of 1928 probably not less than 60 per cent of the timber output of this region was yarded with tractors of the track-laying type. This remarkable increase in the use of tractors has come about largely for two reasons : First, the power employed is split up into several units with the attendant possibility of employing power in proportion to the size of the load ; and second, there is con- siderable flexibility in application to use, for the same unit that hauls logs can also build railroads, raise and rig spar poles, move other equipment or do many of the innumerable other jobs incidental to a logging operation. With this wide use of tractors, a knowledge of the factors affecting costs is important not only to observe the relative effects of such factors but also to secure that coordination among yarding units and between yarding and loading units which will result in the lowest cost per thousand board feet of timber handled. -
