A loader, also called a front loader, front end loader, bucket loader, scoop loader or shovel, is a type of tractor, usually wheeled, that uses a wide square tilting bucket on the end of movable arms to lift and move material.
The 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. The bucket can also be augmented with devices like a bale grappler for handling large bales of hay or straw.
Large loaders, such as the Caterpillar 950G, Volvo L120E, Caterpillar 966G, or Hitachi ZW310 usually have only a front bucket and are called Front Loaders, whereas small loader tractors are often also equipped with a small backhoe and are called backhoe loaders or loader backhoes.
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 (exact number varies with the model) of earth. The front loader's 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.
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 snowbasket but usually they use a snowplow attachment. They clear snow from streets and highways and also parking lots. They sometimes load the snow into dump trucks which haul it away
Unlike most bulldozers, some loaders are wheeled and not tracked. However, track loaders do exist. They are successful where sharp edged materials or nails in construction debris would damage rubber wheels. Wheels provide better mobility and speed and do not damage paved roads as much as tracks, but this comes at the cost of reduced traction.
Unlike backhoes or 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 a heavier weight. Articulated steering also gives reduced turning radius (and therefore higher 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 come in handy. The problem is that when the machine is "twisted" to one side and a heavy load is lifted high, it has a bigger risk of turning over to the "wide" side.
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 Caterpillar, Volvo, Komatsu and Liebherr.

Backhoe loader, also called a Loader backhoe, is an engineering vehicle, which consists of a tractor, front shovel/bucket and small backhoe in the rear. Due to its (relatively) small size and versatility, backhoe loaders are very common in urban engineering and small construction projects (such as building a small house, fixing city roads etc).
Invented in Burlington, Iowa in 1957 the Backhoe loader (note: this needs checking - may have been invented in the UK by Joseph Cyril Bamford, founder of JCB, whose first tractor equipped with both a backhoe and a front mounted loading bucket was completed in 1953) is probably the most common variation of the classic farm tractor. As the name implies, it has a loader assembly on the front and a backhoe on the back. When both the loader and the backhoe are permanently attached it is almost never called a tractor, not generally used for towing and usually does not have a PTO. When the backhoe is permanently attached, the machine usually has a seat that can swivel to the rear to face the hoe controls. Removable backhoe attachments almost always have a separate seat on the attachment itself.
Backhoe-loaders are very common and can be used for a wide variety of tasks: construction, small demolitions, light transportation of building materials, powering building equipment, digging holes/excavating, breaking asphalt, and paving roads. The backhoe bucket can often be replaced with other tools such as a breaker for smashing concrete and rock. Some loader buckets have a retractable bottom or "clamshell", enabling it to empty its load more quickly and efficiently. Retractable-bottom loader buckets are also often used for grading and scraping. The front assembly may be a removable attachment or permanently mounted. Often the bucket can be replaced with other devices or tools. The backhoe loader must be equipped with a tool coupler in order to mount different attachments to the loader. A tool coupler consists of two hydraulic cylinders on the end of the loader arm assembly which can expand and retract allowing different tools to be attached to the unit.
Because the design is intrinsically top-heavy and the swinging weight of the hoe could cause the vehicle to tip, most backhoes use hydraulic outriggers when digging and lower the loader bucket for additional stability. This means that the bucket must be raised and the outriggers retracted when the vehicle needs to change positions, reducing efficiency. For this reason many companies offer miniature tracked excavators, which sacrifice the loader function for increased digging efficiency.
Their relatively small frame and precise control make backhoe-loaders very useful and common in urban engineering projects such as construction and repairs in areas too small for larger equipment. Their versatility and compact size makes them one of the most popular urban construction vehicles. For larger projects, a tracked excavator is generally used.Backhoe Operator Training/Certification
The National Association of Heavy Equipment Training Schools is the primary educational certification body for the backhoe industry.
Trivia

• The cutting of network cables during road repairs is now so common, that network engineers often refer to "backhoe fade" as an inevitable cause of communications problems.

• A heavy, driver-operated machine for clearing and grading land, usually having continuous treads and a broad hydraulic blade in front.
• An overbearing person; a bully The bulldozer as we know it, "a large caterpillar tractor with a plow on the front end for moving earth," pushed its way into our vocabulary by 1930. It was noted in the magazine Water Works and Sewerage for June of that year: "The bulldozer is built for heavy duty." The name suggests a machine with the strength of a bull.
  However, the first bulldozers back in the 1870s were not machines at all, nor bulls. They were people who could be said to give others a dose of maltreatment fit for a bull. In Louisiana during Reconstruction, bulldozers were racist bullies. According to an account in a New York newspaper of 1877, they were "an organization of armed white men, whose ostensible business it is to keep the Negroes from stealing the cotton crop. On election day, however, the 'Bulldozers' go gunning for Negroes who manifest a disposition to vote the Republican ticket." That year the Congressional Record reported, "A band of bull-dozers came into Saint Francisville [Louisiana], and by their yelling and hallooing...put the entire inhabitants in a mortal terror."
  But bulldozing was not confined to the South, nor to racist attacks. In 1892, for example, the Louisville Courier-Journal wrote, "The people of Louisville...will never surrender their rights to Johnny Davenport's proposed gang of ballot-box stuffers and bulldozers." And politicians declared that they should not, or would not, be bulldozed.
  Bulldozer so effectively describes the force of the modern machine, able to overpower the resistance of the earth in a way that pick and shovel could never do, that it is no wonder that the term was appropriated for the earthmoving engine. To bulldoze still means "to intimidate, to push through regardless of opposition." But because someone chose to give the name bulldozer to a machine, we no longer associate the word with mean-spirited humans.A bulldozer is a very powerful crawler (caterpillar tracked tractor) equipped with a blade. The term "bulldozer" is often used to mean any heavy engineering vehicle, but precisely, the term refers only to a tractor (usually tracked) fitted with a dozer blade. That is the meaning used herein.
  The first bulldozers were adapted from farm Holt tractors that were used to plough fields. Their versatility insoft ground for logging and road building, lead directly to them becoming the armoured tank in the first war.
  In 1923, a young farmer named James Cummings and a draftsman named J. Earl McLeod made the first designs for a bulldozer. A replica is on display at the city park in Morrowville, Kansas where the two built the first bulldozer.[1]
  By the 1920s, tracked vehicles became common, particularly the Caterpillar 60. To dig canals, raise earth dams, and do other earthmoving jobs, these tractors were equipped with a large thick metal plate in front. This thick metal plate (it got its curved shape later) is called a "blade". The blade peels layers of soil and pushes it forward as the tractor advances. Several specialised blades have been developed: for high volume loads such as coal, rakes to remove only larger boulders, or blades with razor sharp edges to cut tree stumps. In some early models the driver sat on top in the open without a cabin. These attachments, home built or by small equipment manufacturers of attachments for wheeled and crawler tractors and trucks, appeared by 1929, widespread acceptance of the bull-grader does not seem to appear before the mid-1930's, and the addition of powered down force made them the preferred excavation machine for large and small contractors alike by the 1940's, by which time the term "bulldozer" referred to the entire machine and not just the attachment.
  Over the years, when engineers needed equipment to complete large scale earthworks, firms like the CAT, Komatsu, Fiat-Allis, John Deere, International Harvester, Case, Liebherr, Terex and JCB started to manufacture large tracked-type earthmoving machines. They were large, noisy, and powerful, and therefore nicknamed "bulldozer".
  Through the years, bulldozers got bigger, more powerful, and more sophisticated. Important improvements include more powerful engines, more reliable drive trains, better tracks, raised cabins, and hydraulic (instead of early models' cable operated) arms that enable more precise manipulation of the blade and automated controls. As an option, bulldozers can be equipped with a rear ripper claw to loosen rocky soils or to break up pavement (roads).
  The best known maker of bulldozers is probably the Caterpillar Tractor Company, which earned its reputation for making tough durable reliable machines. Although these machines began as modified farm tractors, they became the mainstay for big civil construction projects, and found their way into use by military construction units throughout the world. Their best known model, the Caterpillar D9, was also used to clear mines and demolish enemy structures.
  History of the word
  
  • Around 1880: In the USA, a "bull-dose" was a large and efficient dose of any sort of medicine or punishment. 'Bull-dosing' meant a severe whipping or coercion, or other intimidation such as at gunpoint.
  • 1886: "bulldozer" meant a large-caliber pistol and the person who wielded it.
  • Late 1800s: "bulldozing" meant using big force to push over or through any obstacle.
  • Later: applied to the vehicle.
  These appeared as early as 1929, but were known as "bull grader" blades, the term "bulldozer blade" does not appear to come into widespread use until the mid 1930's and now refers to the whole machine not just the attachment.
  Description
  Most often, bulldozers are large and powerful tracked engineering vehicles. The tracks give them excellent ground hold and mobility through very rough terrain. Wide tracks help distribute the bulldozer's weight over large area (decreasing pressure), thus preventing it from sinking in sandy or muddy ground. Extra wide tracks are known as 'swamp tracks'. Bulldozers have excellent ground hold and a torque divider designed to convert the engine's power into dragging ability , letting the bulldozer use its own weight to push very heavy things and remove obstacles that are stuck in the ground. The Caterpillar D9, for example, can easily tow tanks that weigh more than 70 tons. Because of these attributes, bulldozers are used to clear areas of obstacles, shrubbery, burnt vehicles, and remains of structures.
  Sometimes a bulldozer is used to push another piece of earthmoving equipment known as a "scraper". The towed Fresno Scraper, invented in 1883 by James Porteous, was the first design to enable this to be done economically, removing the soil from the cut and depositing it elsewhere on shallow ground (fill). Many dozer blades have a reinforced center section with this purpose in mind, and are called "bull blades."
  The bulldozer's primary tools are the blade and the ripper.
  Ripper
  The ripper is the long claw-like device on the back of the bulldozer. Rippers can come singly (single shank) or in groups or two or more (multi shank rippers). Usually, a single shank is preferred for heavy ripping. The ripper shank is fitted with a replaceable tungsten steel alloy tip.
  Ripping rock lets the ground surface rock be broken into small rubble easy to handle and transport, which can then be removed so grading can take place. Agricultural ripping lets rocky or very hard earth be broken up so otherwise unploughable land can be farmed. For example, much of the very best land in the California wine country consists of old lava flows: with heavy bulldozers such as the Caterpillar D9 and the Caterpillar D11 the lava is shattered allowing practical agriculture for the wine industry. Also, hard earth can be ripped and decompacted to allow planting of orchards which otherwise could not grow on the land.
  Blade
  The bulldozer blade is a piece of heavy metal plate, installed on the front of the tractor, with the aim of pushing things, handle rough obstacles and shoving sand, dirt and debris. The dozer blade on front of the tractor usually comes in 3 varieties:
  
  1. A Straight Blade ("S-Blade") which is short and has no lateral curve, no side wings, and can be used for fine grading.
  2. A Universal Blade ("U-Blade") which is tall and very curved, and has large side wings to carry more material.
  3. A "S-U" combination blade which is shorter, has less curvature, and smaller side wings.This blade is typically used for pushing piles of large rocks, such as at a quarry.
  Modifications
  Bulldozers have been further modified over time to evolve into new machines which are capable of working in ways that the original bulldozer can not. One example is that loader tractors were created by removing the blade and substituting a large volume bucket and hydraulic arms which can raise and lower the bucket, thus making it useful for scooping up earth and loading it into trucks. Other modifications to the original bulldozer include making it smaller to let it operate in small work areas where movement is limited, such as in mining. A very small bulldozer is sometimes called a calfdozer: see the image at this link and this link.
  Nevertheless, the original earthmoving bulldozers are still irreplaceable as their tasks are concentrated in deforestation, earthmoving, ground leveling, and road carving. The heavy bulldozers are mainly employed to level the terrain to make it fit to construct on. The construction, however, is mainly done by small bulldozers and loader tractors
  Bulldozers can be found on large and small scale construction sites, mines, roadsides, military bases, heavy industry factories, and large governmental projects.
  Some bulldozers, especially bulldozers in military usage, have been fitted with armor in order to protect the driver from enemy fire, thus enabling the bulldozer to operate in battle zones. The most famous armored bulldozer is probably the IDF Caterpillar D9, used by the Israeli Defense Forces for detonating explosive charges and demolishing structures under fire. Caterpillar does not make nor install the armor—that is entirely the work of the IDF. However, various users including the US military buy armor kits from the IDF and fit them onto their own D9s. The design varies but the armor kit on average adds 10 tonnes to the weight of the bulldozer, which weighs about 49 tonnes without the armor.

  An excavator, also called a 360-degree excavator or digger, sometimes abbreviated simply to a 360, is an engineering vehicle consisting of a backhoe and cab mounted on a pivot (a rotating platform, like a Lazy Susan) atop an undercarriage with tracks or wheels. Their design is a natural progression from the steam shovel.
  Note: the term excavator is sometimes used as a general term for any piece of digging equipment. Tracked excavators are sometimes called trackhoes.Usage
  Excavators are used in many roles:
  
  • Brush cutting with hydraulic attachments
  • Digging of trenches, holes, foundations
  • Demolition
  • General grading/landscaping
  • Heavy lift, e.g. lifting and placing of pipes
  • Mining, especially, but not only open-pit mining
  • River dredging Configurations
  Excavators come in a wide variety of sizes. The smaller ones are called a mini-excavator or compact excavator. One manufacturer's largest model weighs 84,980 kg (187,360 lb) and has a maximum bucket size of 4.5 m3 (5.9 yd3). The same manufacturer's smallest mini-excavator weighs 1470 kg (3240 lb), has a maximum bucket size of 0.036 m3 (0.048 yd3) and the width of its tracks can be adjusted to 89 cm (35 inches). Another company makes a mini excavator that will fit through a doorway with tracks that can be adjusted to only 70 cm (28 inches) wide.
  Often the bucket can be replaced with other tools like a breaker, a grapple or an auger. Excavators are usually employed together with loaders and bulldozers. Most smaller excavators have a small backfill (or dozer-) blade. This is a horizontal bulldozer-like blade attached to the undercarriage and is used for pushing removed material back into a hole.
  A Skid loader or skid-steer loader is a rigid frame, engine-powered machine with lift arms used to attach a wide variety of labor-saving tools or attachments. Skid-steer loaders are four-wheel drive vehicles with the left-side drive wheels independent of the right-side drive wheels. By having each side be independent of the other, wheel speed and direction of rotation of the wheels determine the direction the loader will turn.
  Skid-steer loaders can turn in their own tracks which makes them extremely maneuverable and valuable for applications that require a compact, agile loader.
  Unlike in a conventional front loader, the lift arms in these machines lie alongside the driver with the major pivot points behind the driver's shoulders. Because of the operator's proximity to moving booms and buckets, early skid loaders were not as safe as conventional front loaders, particularly during entry and exit of the operator. Modern skid loaders have fully-enclosed cabs and other safety features to protect the operator from injury. Like other front loaders it can scrape material from one location to another, carry material in its bucket or load material into a truck or trailer.Operation
  A Skid loader can sometimes be used in place of a large excavator by digging a hole from the inside. The skid loader first digs a ramp leading to the edge of the desired excavation. It then uses the ramp to carry material out of the hole. The skid loader reshapes the ramp making it steeper and longer as the excavation deepens. This method is particularly useful for digging under a structure where overhead clearance does not allow for the boom of a large excavator, e.g. for the purpose of digging a basement under an existing house.
  The conventional bucket of many skid loaders can be replaced with a variety of specialized buckets or attachments, many powered by the loader's hydraulic system. Examples of such substitutions are backhoe, hydraulic breaker, pallet forks, angle broom, sweeper, auger, mower, snow blower, stump grinder, tree spade, trencher, and wheel saw.
  The very first three-wheeled, front-end loader was invented by brothers Cyril and Louis Keller (manufacturer) in their machinist blacksmith shop in Rothsay, Minnesota, in 1957. The Kellers built the loader to help a nearby farmer, Eddie Velo, mechanize the process of cleaning turkey manure from his two-story pole barn. The light and compact machine, with its rear caster wheel, was able to turn around within its own length, while performing the same tasks as a conventional front-end loader.
  The Melroe brothers, whose Melroe Manufacturing Company was down the road in Gwinner, N.D., purchased the rights to the Keller loader in 1958 and hired the Kellers to continue refining their invention. As a result of this partnership, the M-200 Melroe self-propelled loader was introduced at the end of that year. It featured two independent front-drive wheels and a rear caster wheel, a 12.9-hp engine and a 750-lb. lift capacity. Just two years later, they replaced the caster wheel with a rear axle and introduced the M-400, the first four-wheel, skid-steer loader. The “Bobcat” name was added in 1962 to describe the key attributes of the machine: tough, agile, and quick. The term "Bobcat" is sometimes used as a generic term for skid-steer loaders. The M-440 was powered by a 15.5-hp engine and had an 1100-lb. rated operating capacity. Skid-steer loader development continued into the mid-1960s with the introduction of the M600 loader.
  In the years since, the Bobcat skid-steer loader has experienced quite a few changes, including the development of a hydrostatic drive system, rollover protective cab structures, radius and vertical path lift-arm configurations, deluxe instrumentation and heating and air conditioning.
  Today, in addition to rubber tire skid-steer loaders, there are all-wheel steer loaders and compact track loaders. Compact track loaders feature a rubber track undercarriage that provide better digging and pushing performance. Compact track loaders provide less ground disturbance and feature better traction and flotation in soft, wet, muddy, and sandy conditions.
  Compact Hydraulic Excavators The compact hydraulic excavator is somewhat unique from other construction equipment in that all movement and functions of the machine are accomplished through the transfer of hydraulic fluid. The compact excavator's work group and blade are activated by hydraulic fluid acting upon hydraulic cylinders. The excavator's slew (rotation) and travel functions are also activated by hydraulic fluid powering hydraulic motors.
  In recent years, hydraulic excavator capabilities have expanded far beyond excavation tasks. With the advent of hydraulic powered attachments such as breakers, clamps, augers, and compactors, the excavator is frequently used in many applications other than excavation and actually serves as an effective attachment tool carrier. Many excavators feature quick-attach mounting systems for simplified attachment mounting, dramatically increasing the machine's utilization on the jobsite.
  Mini Loaders Mini skid-steer loaders or compact utility loaders are even smaller and include 'walk behind' cable or radio controlled skid loaders and the slightly larger platform skid loaders. Platform skid loaders have a small platform on the back instead of a seat for the operator to stand on.
  Toolcat Utility Work Machine The Toolcat utility work machine combines the features of a utility loader (lifting, loading and material handling), utility vehicle/pickup truck (hauling cargo and towing a trailer) and attachment carrier (operating attachments for various applications) into one platform. It's designed to excel at large property maintenance, commercial groundskeeping and surface landscaping tasks. It can take an operator and a co-worker to the jobsite and complete the job like no other machine can — by out-lifting, out-towing and out-hauling other machines.
