A skid-steer loader is an engine powered machine that consists of a small and rigid frame. It is outfitted along with lift arms that are utilized to attach to a large variety of labor saving attachments and tools. Normally, skid-steer loaders are four-wheel drive vehicles which have the left-hand side wheels working independent of the right-hand side wheels, even if several models are outfitted along with tracks instead. On the four-wheel models, having each side independent of each other enables the wheel speed and rotation direction of the wheels to know what direction the loader will turn.
These machines are capable of "pirouette" or likewise known as zero-radius turning. This particular feature makes skid-steer loaders extremely valuable and maneuverable for applications which need an agile and compact loader.
The lift arms on the skid-steer loader are situated at the side of the driver together with pivots behind the driver's shoulders. These features makes the skid-steer loader different compared to the conventional front loader. Due to the operator's proximity to moving booms, early skid loaders were not as safe as conventional front loaders, specially throughout the operator's exit and entry. Today's' modern skid-steer loaders have various features to protect the driver including fully-enclosed cabs. Like various front loaders, the skid-steer model could push materials from one place to another, is capable of loading material into a trailer or a truck and can carry material in its bucket.
There are numerous times where the skid-steer loader can be utilized instead of a large 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 remarkably useful way for digging underneath a structure where there is not enough overhead clearance for the boom of a big excavator. For instance, this is a common situation when digging a basement underneath an existing structure or home.
The skid-steer loader accessories add much flexibility to the machine. Like for example, conventional buckets on the loaders can be replaced accessories powered by their hydraulics consisting of snow blades, cement mixers, pallet forks, backhoes, tree spades, sweepers and mowers. Various other popular specialized buckets and attachments include trenchers, angle booms, dumping hoppers, wood chipper machines, grapples, tillers, stump grinders rippers, wheel saws and snow blades.
In the year 1957, the very first 3-wheeled, front-end loader was invented in Rothsay, in the state of Minnesota by brothers Louis and Cyril Keller. The brothers invented the loader so as to help a farmer mechanize the method of cleaning turkey manure from his barn. This machine was light and compact and consisted of a rear caster wheel which allowed it to turn around and maneuver within its own length, allowing it to carry out similar tasks as a traditional front-end loader.
The Melroe brothers of Melroe Manufacturing Company in Gwinner, N.D. obtained in the year 1958, the rights to the Keller loader. The company then hired the Keller brothers to assist with development of the loader. The M-200 Melroe was actually the result of this partnership. This particular model was a self-propelled loader which was introduced to the market during the year 1958. The M-200 Melroe featured a a rear caster wheel, a 12.9 HP engine, a 750 lb lift capacity and two independent front drive wheels. By 1960, they changed the caster wheel along with a rear axle and launched the first 4 wheel skid steer loader that was referred to as the M-400.
The M-400 shortly became the Melroe Bobcat. Normally the term "Bobcat" is used as a generic term for skid-steer loaders. The M-440 was powered by a 15.5 HP engine and had 1100 lb rated operating capacity. The business continued the skid-steer development into the mid 1960s and introduced the M600 loader.
Many manufacturers have their own models of the skid steer loader that is simply known as a Skidsteer within the construction trade. Gehl Company, LiuGong, ASV, Hyundai, JCB, Catterpillar, Bobcat, Komatsu, Mustang, John Deere, JLG and New Holland are a few for example, among others.
