Feller Buncher
A feller buncher is a type of harvester used in logging. It is a motorized vehicle with an attachment that can rapidly gather and cut a tree before felling it. ''Feller'' is a traditional name for someone who cuts down trees, and ''bunching'' is the skidding and assembly of two or more trees. A feller buncher performs both of these harvesting functions and consists of a standard heavy equipment Heavy equipment, heavy machinery, earthmovers, construction vehicles, or construction equipment, refers to heavy-duty vehicles specially designed to execute construction tasks, most frequently involving earthwork operations or other large con ... base with a tree-grabbing device furnished with a chainsaw, circular saw or a lopper, shear—a pinching device designed to cut small trees off at the base. The machine then places the cut tree on a stack suitable for a skidder, forwarder, or yarder for transport to further processing such as delimbing, Log bucking, bucking, loading, or woo ...

Chainsaw
A chainsaw (or chain saw) is a portable handheld power saw, power saw that cuts with a set of teeth attached to a rotating chain driven along a guide bar. Modern chainsaws are typically gasoline or electric and are used in activities such as tree felling, limbing, Log bucking, bucking, pruning, cutting firebreaks in wildland fire suppression, harvesting of Wood fuel#Firewood, firewood, for use in Chainsaw carving, chainsaw art and chainsaw mills, for cutting concrete, and cutting ice. Precursors to modern chainsaws were first used in surgery, with patents for wood chainsaws beginning in the late 19th century. A chainsaw comprises an engine, a drive mechanism, a guide bar, a cutting chain, a tensioning mechanism, and safety features. Various safety practices and working techniques are used with chainsaws. History In surgery A "flexible saw", consisting of a fine serrated link chain held between two wooden handles, was pioneered in the late 18th century (–1785) by two Scot ...

Harvester (forestry)
A harvester is a type of heavy forestry vehicle employed in cut-to-length logging operations for tree felling, felling, delimbing and log bucking, bucking trees. A forest harvester is typically employed together with a skidder#Grapple skidders, skidder that hauls the logging, logs to a roadside landing, or a forwarder to pick up and haul away. History Forest harvesters were mainly developed in Sweden and Finland and today do practically all of the commercial felling in these countries. The first fully mobile timber "harvester", the PIKA model 75, was introduced in 1973Rihko Haarlaa: Organization and technology of wood harvesting in Finland.' Department of Forest Resource Management, University of Helsinki, Finland. 1992. by Finnish systems engineer Sakari Pinomäki and his company PIKA Forest Machines. The first single grip harvester head was introduced in the early 1980s by Swedish company SP Maskiner. Their use has become widespread throughout the rest of Northern Europe, ...

Logging
Logging is the process of cutting, processing, and moving trees to a location for transport. It may include skidder, skidding, on-site processing, and loading of trees or trunk (botany), logs onto logging truck, trucksSociety of American Foresters, 1998. Dictionary of Forestry. or flatcar#Skeleton car, skeleton cars. 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. 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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cut-to-length Logging
Cut-to-length logging (CTL) is a mechanized harvesting system in which trees are delimbed and ''cut to length'' directly at the tree stump, stump. CTL is typically a two-man, two-machine operation with a harvester (forestry), harvester felling, delimbing, and Log bucking, bucking trees and a forwarder transporting the logs from the felling to a landing area close to a road accessible by trucks. CTL is the primary logging method in European countries, while full-tree logging and the even older technique of tree-length logging are more popular in North America and less developed countries, where tree sizes can exceed the capacity of the harvester's felling head, i.e., tree stems with a butt diameter of over 90 centimeters. CTL lends itself to timber harvesting in Plantation, plantation forestry where stems are often harvested before they reach large dimensions. Advantages compared to full-tree logging *Cleaner wood since the logs are not skidder, skidded on the ground to the landin ...

Lumberjack
Lumberjack is a mostly North American term for workers in the logging industry who perform the initial harvesting and transport of trees. The term usually refers to loggers in the era before 1945 in the United States, when trees were felled using hand tools and dragged by oxen to rivers. The work was difficult, dangerous, intermittent, low-paying, and involved living in primitive conditions. However, the men built a traditional culture that celebrated strength, masculinity, confrontation with danger, and resistance to modernization. Term The term lumberjack is of Canadian derivation. The first attested use of the term combining its two components comes from an 1831 letter to the Cobourg, Ontario, ''Star and General Advertiser'' in the following passage: "my misfortunes have been brought upon me chiefly by an incorrigible, though perhaps useful, race of mortals called lumberjacks, whom, however, I would name the Cossacks of Upper Canada, who, having been reared among the ...

Log Bucking
A crew of log buckers with crosscut saws in 1914. Bucker limbing dead branch stubs with a chainsaw, also known as knot bumping Bucker making a bucking cut with a chainsaw Bucking is the process of cutting a felled and delimbed tree into logs. Significant value can be lost by sub-optimal bucking because logs destined for plywood, lumber, and 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''. Bucking may be done in a variety of ways depending on the logging operation. Trees that have been previously felled and moved to a landing with a log skidder are spread out for processing. While many of the limbs have broken off during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 synonym ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
