Pole Saw
A polesaw (also pole saw or giraffe saw) is a saw attached to a pole or long handle that is used for pruning tree branches that are beyond arm's reach. A polesaw allows its user to cut high branches without the use of a ladder. Polesaws can be manual or motorized. A polesaw is common equipment for phone- and powerline workers to prune tree limbs entangled with overhead cable An overhead cable is a cable for the transmission of information, laid on utility poles. Overhead telephone and cable TV lines are common in North America. These poles sometimes carry overhead power lines for the supply of electric power.

Gardening
Gardening is the process of growing plants for their vegetables, fruits, flowers, herbs, and appearances within a designated space. Gardens fulfill a wide assortment of purposes, notably the production of Aesthetics, aesthetically pleasing areas, Medication, medicines, cosmetics, dyes, foods, poisons, wildlife habitats, and saleable goods (see market gardening). People often partake in gardening for its Therapy, therapeutic, health, educational, Culture, cultural, Philosophy, philosophical, Environmental protection, environmental, and Religion, religious benefits. Gardening varies in scale from the 800 hectare Palace of Versailles, Versailles gardens down to container gardens grown inside. Gardens take many forms; some only contain one type of plant, while others involve a complex assortment of plants with no particular order. Gardening can be difficult to differentiate from Agriculture, farming. They are most easily differentiated based on their primary objectives. Farming pri ...

Pruning
Pruning is the selective removal of certain parts of a plant, such as branches, buds, or roots. It is practiced in horticulture (especially fruit tree pruning), arboriculture, and silviculture. The practice entails the targeted removal of diseased, damaged, dead, non-productive, structurally unsound, or otherwise unwanted plant material from crop and landscape plants. In general, the smaller the branch that is cut, the easier it is for a woody plant to compartmentalize the wound and thus limit the potential for pathogen intrusion and decay. It is therefore preferable to make any necessary formative structural pruning cuts to young plants, rather than removing large, poorly placed branches from mature plants. Woody plants may undergo a process referred to as ''self-pruning'', where they will drop twigs or branches which are no longer producing more energy than they require. It is theorized that this process can also occur in response to lack of water, in order to reduce the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Lineworker
A lineworker (also called a lineman or powerline worker) constructs and maintains the electric power transmission, electric transmission and electricity distribution, distribution facilities that deliver electrical energy to industrial, commercial, and residential establishments. A lineworker installs, services, and emergency repairs electrical lines in the case of lightning, wind, ice storm, or ground disruptions. Whereas those who install and maintain electrical wiring inside buildings are electrician, electricians, lineworkers generally work at outdoor installations. History The occupation had begun in 1844 when the first telegraph wires were strung between Washington, D.C., and Baltimore, Maryland, Baltimore carrying the famous message of Samuel Morse, "What hath God wrought?" The first telegraph station was built in Chicago, Illinois, Chicago in 1848, by 1861 a web of lines spanned the United States and in 1868 the first permanent telegraph cable was successfully laid across ...

Overhead Cable
An overhead cable is a cable for the transmission of information, laid on utility poles. Overhead telephone and cable TV lines are common in North America. These poles sometimes carry overhead power lines for the supply of electric power. Power supply companies may also use them for an in-house communication network. Sometimes these cables are integrated in the ground or power conductor. Otherwise an additional line is strung on the pylons, usually on the body of the pylon in the height of a crossbar. At several lines built by the former power supply company EVS (now part of EnBW) in Baden-Württemberg, Germany, such cables are attached like a garland on the ground conductor or on an auxiliary rope. Although many of these cables were replaced by ground conductors with integrated communication cable or free-spun communication cables many of these cables are still in use.

Musculoskeletal Injury
Musculoskeletal injury refers to damage of muscular or skeletal systems, which is usually due to a strenuous activity and includes damage to skeletal muscles, bones, tendons, joints, ligaments, and other affected soft tissues. In one study, roughly 25% of approximately 6300 adults received a musculoskeletal injury of some sort within 12 months—of which 83% were activity-related. Musculoskeletal injury spans into a large variety of medical specialties including orthopedic surgery (with diseases such as arthritis requiring surgery), sports medicine, emergency medicine ( acute presentations of joint and muscular pain) and rheumatology (in rheumatological diseases that affect joints such as rheumatoid arthritis). Musculoskeletal injuries can affect any part of the human body including; bones, joints, cartilages, ligaments, tendons, muscles, and other soft tissues. Symptoms include mild to severe aches, low back pain, numbness, tingling, atrophy and weakness. These injuries are a re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
