1LoadersOverviewBasic Concept.A loader is a type of construction equipment (engineering vehicle) machinery that is primarily used to “load“ material into another type of machinery (dump truck, conveyor belt, rail-car, etc.).Loaders are used mainly for uploading materials into trucks, laying pipe, clearing rubble, and digging. A loader is not the most efficient machine for digging as it cannot dig very deep below the level of its wheels, like a backhoe can. Their deep bucket can usually store about 3-6 cubic meters of earth. The front loaders bucket capacity is much bigger than a bucket capacity of a backhoe loader. Loaders are not classified as earthmoving machinery, as their primary purpose is other than earthmoving.Unlike most bulldozers, most loaders are wheeled and not tracked, although track loaders are common. They are successful where sharp edged materials in construction debris would damage rubber wheels, or where the ground is soft and muddy. Wheels provide better mobility and speed and do not damage paved roads as much as tracks but provide less traction.Unlike standard tractors fitted with a front bucket, many large loaders do not use automotive steering mechanisms. Instead, they steer by a hydraulically actuated pivot point set exactly between the front and rear axles. This is referred to as “articulated steering“ and allows the front axle to be solid, allowing it to carry greater weight. Articulated steering provides better maneuverability for a given wheelbase. Since the front wheels and attachment rotate on the same axis, the operator is able to “steer“ his load in an arc after positioning the machine, which can be useful 2the loader assembly may be a removable attachment or permanently mounted. Often the bucket can be replaced with other devices or tools-for example, many can mount forks to lift heavy pallets or shipping containers, and a hydraulically-opening “clamshell“ bucket allows a loader to act as a light dozer or scraper.In construction areas loaders are also used to transport building materials - such as bricks, pipe, metal bars, and digging tools - over short distances. Loaders are also used for snow removal, using their bucket or a snow basket, but usually using a snowplow attachment. They clear snow from streets, highways and parking lots. They sometimes load snow into dump trucks for transport.Front loaders gained popularity during the last two decades, especially in urban engineering projects and small earthmoving works. Many engineering vehicle manufacturers offer a wide range of loaders, the most notable are those of John Deere, Caterpillar, Case, Volvo, Komatsu and Liebherr.Applications1 23 4 5 637 89 1011 121. loading materials；2. earthmoving；3. forestry engineering；4. snow removing；5. underground work；6. loading and unloading；7. pipe laying；8. maintain pavement；9. land clearing；10. garden work；11. rolling compaction；12. tunnel constructionTypes1 23 445 67 89 101. mini type loader；2.small type wheel loader；3.medium type wheel loader；4.large type wheel loader；5. track-type loader；6. skid steer loader；7. underground mining loader；8. multi terrain loader；9. wheel backhoe loader；10. side dumping loaderComponents and FeaturesComponentsBasic Components51. bucket；2. front axle；3.instrumentation console；4. cab and operating system；5.engine and transmission system；6. engine hood；7. counterweight；8. rear axle；9. rear frame；10. electrical system；11. front frame；12. mudguard；13. boom；14. rocker arm cylinder；15. connecting rod；16. rocker arm；17. boom cylinder；18. frameHydro mechanical Transmission System61.engine；2. torque converter；3. power shifting transmission box；4. front axle；5.
