A skid-steer loader is an engine powered machinery that consists of a rigid and small frame. It is outfitted together with lift arms that are used to connect to a large variety of labor saving attachments and tools. Typically, skid-steer loaders are four-wheel drive vehicles which have the left-hand side wheels working independent of the right-hand side wheels, even though various models are outfitted with tracks instead. On the four-wheel models, having each side independent of each other allows the wheel speed and rotation direction of the wheels to know what direction the loader will turn.
These equipment could "pirouette" or also known as zero-radius turning. This feature makes skid-steer loaders extremely valuable and maneuverable for applications that require an agile and compact loader.
On a skid-steer loader, the lift arms are next to the driver along with pivot points at the back of the driver's shoulders. This makes them different than a conventional front loader. Due to the operator's nearness to moving booms, early skid loaders were not as safe as conventional front loaders, specially throughout the operator's exit and entry. Modern skid-steer loaders these days have numerous features to protect the driver like fully-enclosed cabs. Similar to several front loaders, the skid-steer model can push materials from one place to another, is capable of loading material into a truck or trailer and could carry material in its bucket.
There are numerous times where the skid-steer loader can be used in place of a big excavator on the job location for digging holes from the inside. To begin, the loader digs a ramp to be used to excavate the material out of the hole. As the excavation deepens, the machinery reshapes the ramp making it longer and steeper. This is a very functional method for digging under a structure where there is not adequate overhead clearance for the boom of a large excavator. Like for instance, this is a common scenario when digging a basement under an existing house or structure.
The skid-steer loader attachments add much flexibility to the machinery. For example, conventional buckets on the loaders could be replaced attachments powered by their hydraulics including snow blades, cement mixers, pallet forks, backhoes, tree spades, sweepers and mowers. Various other popular specialized attachments and buckets include wood chipper machines, grapples, tillers, stump grinder rippers, wheel saws, snow blades, trenchers, angle booms and dumping hoppers.
In the year 1957, the very first 3-wheeled, front-end loader was invented in Rothsay, Minnesota by brothers Cyril and Louis Keller. The brothers invented the loader so as to help a farmer mechanize the method of cleaning turkey manure from his barn. This machinery was compact and light and consisted of a rear caster wheel that enabled it to turn around and maneuver within its own length, allowing it to execute similar work as a conventional front-end loader.
The Melroe brothers of Melroe Manufacturing Company in Gwinner, N.D. acquired in the year 1958, the rights to the Keller loader. The business then employed the Keller brothers to assist with development of the loader. The M-200 Melroe was actually the end result of this partnership. This particular model was a self-propelled loader which was launched to the market in 1958. The M-200 Melroe featured a a 750 lb capacity, two independent front drive wheels, a rear caster wheel and a 12,9 HP engine. By the year 1960, they changed the caster wheel along with a rear axle and introduced the first 4 wheel skid steer loader which was known as the M-400.
The M-400 shortly became the Melroe Bobcat. usually the term "Bobcat" is used as a generic term for skid-steer loaders. The M-440 had an 1100 lb rated operating capacity and was powered by a 15.5 HP engine. The business continued the skid-steer development into the middle part of the 1960s and introduced the M600 loader.
Various makers have their own models of the skid steer loader which is simply called a Skidsteer in the construction industry. Hyundai, JCB, Caterpillar, Bobcat, Komatsu, Mustang, John Deere, JLG, New Holland, Gehl Company, LiuGong and ASV are some for example, among some.
