Skid Cone
In forestry, a skid cone is a hollow steel or plastic cone placed over the sawn end of a log. When skidding (dragging) logs end-wise, it presents a pointed end that deflects itself past obstacles. Skid cones are most popularly used when skidding single logs behind ATV ATV may refer to: Broadcasting * Amateur television *Analog television Television stations and companies * Ràdio i Televisió d'Andorra * ATV (Armenia) * ATV (Aruba), NBC affiliate * ATV (Australian TV station), Melbourne * ATV (Austria) * AT ...s or light tractors, particularly when a single operator is too occupied with driving to keep a continuous watch behind. Heavy tractors and large logs smash through obstacles. Horse loggers work from behind the horse and have a better view of the moving log. Skid cones are also useful when winching by rope, where it is more difficult to steer a log. Skid cones prevent logs from being stopped by roots, stumps or residual trees while being harvested. It also protects st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forestry
Forestry is the science and craft of creating, managing, planting, using, conserving and repairing forests, woodlands, and associated resources for human and environmental benefits. Forestry is practiced in plantations and natural stands. The science of forestry has elements that belong to the biological, physical, social, political and managerial sciences. Forest management play essential role of creation and modification of habitats and affect ecosystem services provisioning. Modern forestry generally embraces a broad range of concerns, in what is known as multiple-use management, including: the provision of timber, fuel wood, wildlife habitat, natural water quality management, recreation, landscape and community protection, employment, aesthetically appealing landscapes, biodiversity management, watershed management, erosion control, and preserving forests as "sinks" for atmospheric carbon dioxide. Forest ecosystems have come to be seen as the most important comp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

All-terrain Vehicle
An all-terrain vehicle (ATV), also known as a light utility vehicle (LUV), a quad bike, or simply a quad, as defined by the American National Standards Institute (ANSI); is a vehicle that travels on low-pressure tires, with a seat that is straddled by the operator, along with handlebars for steering control. As the name implies, it is designed to handle a wider variety of terrain than most other vehicles. Although it is a street-legal vehicle in some countries, it is not street-legal within most states, territories and provinces of Australia, the United States or Canada. By the current ANSI definition, ATVs are intended for use by a single operator, although some companies have developed ATVs intended for use by the operator and one passenger. These ATVs are referred to as tandem ATVs. The rider sits on and operates these vehicles like a motorcycle, but the extra wheels give more stability at slower speeds. Although most are equipped with three or four wheels, six-wheel mod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
