Choker Setter
A choker setter or choke setter is a logger who attaches cables to logs for retrieval by skidders or skylines. The work process involves the choker setter wrapping a special cable end (choker) around a log and then moving clear so the yarding engineer (e.g. skidder operator) can pull the log to a central area. In clearcutting, fallers will typically cut down all the trees and limb Limb may refer to: Science and technology *Limb (anatomy), an appendage of a human or animal *Limb, a large or main branch of a tree *Limb, in astronomy, the curved edge of the apparent disk of a celestial body, e.g. lunar limb *Limb, in botany, ... and buck them into logs before the choke setters and others arrive to remove the logs.

Logging
Logging is the process of cutting, processing, and moving trees to a location for transport. It may include skidding, on-site processing, and loading of trees or logs onto trucks or skeleton cars. Logging is the beginning of a supply chain that provides raw material for many products societies worldwide use for housing, construction, energy, and consumer paper products. Logging systems are also used to manage forests, reduce the risk of wildfires, and restore ecosystem functions, though their efficiency for these purposes has been challenged. In forestry, the term logging is sometimes used narrowly to describe the logistics of moving wood from the stump to somewhere outside the forest, usually a sawmill or a lumber yard. In common usage, however, the term may cover a range of forestry or silviculture activities. Illegal logging refers to the harvesting, transportation, purchase, or sale of timber in violation of laws. The harvesting procedure itself may be illegal, includin ...

Skidder
A skidder is any type of heavy vehicle used in a logging operation for pulling cut trees out of a forest in a process called "skidding", in which the logs are transported from the cutting site to a landing. There they are loaded onto trucks (or in times past, railroad cars or flumes), and sent to the mill. One exception is that in the early days of logging, when distances from the timberline to the mill were shorter, the landing stage was omitted altogether, and the "skidder" would have been used as the main road vehicle, in place of the trucks, railroad, or flume. Modern forms of skidders can pull trees with a cable/winch (''cable skidder''), just like the old steam donkeys, or with a hydraulic grapple either on boom (''grapple skidder'') or on the back of the frame ''(clambunk skidder)''. History Early skidders were pulled by a team of oxen, horses or mules. The driver would straddle the cart over felled logs, where dangling tongs would be positioned to raise the end of ...

Skyline Logging
Skyline logging (or skyline yarding) is a form of cable logging in which harvested logs are transported on a suspended steel cable (a cableway or "highline") from where the trees are felled to a central processing location. The skyline's cable loop runs around a drive pulley, generally at the central delivery end, and the return pulley at the collection end; the collection-end pulley may be moved radially to other locations within the constraints of the system, and may operate over large areas. Individual logs are attached to the suspended cable by means of choker cables and carriages. A skyline yarder can pull in 5 to 10 logs at a time, using separate chokers. The pulleys are mounted on towers or cranes, other trees, ridges or, in rare cases, helium balloons. See also * Cable logging High Lead logging in Western Oregon Cable logging, also referred to as skyline logging, is a logging method primarily used on the West Coast of North America with yarder, loaders, and ...

Engineer
Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin ) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of an engineer typically include a four-year bachelor's degree in an engineering discipline, or in some jurisdictions, a master's degree in an engineering discipline plus four to six years of peer-reviewed professiona ...

Clearcutting
Clearcutting, clearfelling or clearcut logging is a forestry/ logging practice in which most or all trees in an area are uniformly cut down. Along with shelterwood and seed tree harvests, it is used by foresters to create certain types of forest ecosystems and to promote select species that require an abundance of sunlight or grow in large, even-age stands. Logging companies and forest-worker unions in some countries support the practice for scientific, safety and economic reasons, while detractors consider it a form of deforestation that destroys natural habitats and contributes to climate change. Clearcutting is the most common and economically profitable method of logging. However, it also may create detrimental side effects, such as the loss of topsoil, the costs of which are intensely debated by economic, environmental and other interests. In addition to the purpose of harvesting wood, clearcutting is used to create land for farming. Ultimately, the effects of clearcutt ...

Limbing
Limbing or delimbing is the process of removing branches from a standing or fallen tree trunk. In logging, limbing follows felling. Limbing plays a role in fire prevention by removing branches from live trees that can otherwise serve as part of a fuel ladder allowing a fire to climb from the ground into the tree canopy. A California fire prevention guide recommends to "Remove all tree branches at least 6 feet .8 metersfrom the ground" and "Allow extra vertical space between shrubs and trees." Ready For Wildfire, In , limbing can be synonymous w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Significant value can be lost by sub-optimal bucking because logs destined for plywood, lumber, and wood pulp, pulp each have their own value and specifications for length, diameter, and defects. Cutting from the top down is ''overbucking'' and from the bottom up is ''underbucking''. In British English, the process is called logging-up or crosscutting. Methods A felled and delimbed tree is cut into logs of standard sizes, a process called ''bucking''. A logger who specialises in this job is a ''buck sawyer (occupation), sawyer''. Bucking may be done in a variety of ways depending on the logging operation. Trees that ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Donkey Puncher
A steam donkey or donkey engine is a steam-powered winch once widely used in logging, mining, maritime, and other industrial applications. Steam powered donkeys were commonly found on large metal-hulled multi-masted cargo vessels in the later decades of the Age of Sail on through the Age of Steam, particularly heavily-sailed skeleton-crewed windjammers. A donkey used in forestry, also known as a logging engine, was often attached to a yarder for hauling logs from where trees were felled to a central processing area. The operator of a donkey was known as a donkeyman. Name Steam donkeys acquired their name from their origin in sailing ships, where the "donkey" engine was typically a small secondary engine used to load and unload cargo and raise the larger sails with small crews, or to power pumps. They were classified by their cylinder type – simplex (single-acting cylinder) or duplex (a compound engine); by their connection to the winches (or "drums") – triple-drum, do ...
