A skid-steer loader is an engine powered machine which consists of a rigid and small frame. It is outfitted together with lift arms that are made use of to attach to various labor saving attachments and tools. Typically, skid-steer loaders are four-wheel drive vehicles that have the left-hand side wheels functioning independent of the right-hand side wheels, though some models are outfitted along with tracks instead. On the four-wheel models, having each side independent of each other enables the rotation direction of the wheels and the wheel speed to determine which course the loader would turn.
These machines are capable of "pirouette" or zero-radius turning. This particular feature makes skid-steer loaders exceptionally maneuverable and valuable for applications which require an agile and compact loader.
On a skid-steer loader, the lift arms are beside the driver along with pivot points at the rear of the driver's shoulders. This makes them different as opposed to a conventional front loader. Due to the operator's proximity to moving booms, early skid loaders were not as safe as conventional front loaders, specially during the operator's entry and exit. 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 can push materials from one place to another, can load material into a truck or trailer and could carry material in its bucket.
There are many times where the skid-steer loader could be used rather than a large excavator on the job location for digging holes from the inside. To start, the loader digs a ramp to be used to excavate the material out of the hole. As the excavation deepens, the equipment reshapes the ramp making it longer and steeper. This is a particularly helpful technique for digging below a structure where there is not adequate overhead clearance for the boom of a large excavator. Like for example, this is a common scenario when digging a basement underneath an existing structure or house.
The skid-steer loader accessories add much flexibility to the equipment. Like for example, traditional buckets on the loaders can be replaced attachments powered by their hydraulics comprising backhoes, tree spades, sweepers, mowers, snow blades, cement mixers and pallet forks. Several other popular specialized buckets and attachments comprise wheel saws, snow blades, trenchers, angle booms, dumping hopper, wood chipper machines, grapples, tillers and stump grinders rippers.
The 3-wheeled front end loader was invented during the year 1957, by Louis and Cyril Keller in their hometown of Rothsay, Minnesota. The Keller brothers made this machine so as to help mechanize the process of cleaning in turkey barns. This particular machine was light and compact and had a back caster wheel which enabled it to maneuver and turn around within its own length, enabling it to carry out the same jobs as a traditional front-end loader.
During 1958, the Melroe brothers of Melroe Manufacturing Company in Gwinner, N.D. acquired the rights to the Keller loader. They employed the Keller brothers to continue refining their loader invention. The M-200 Melroe was the end result of this particular partnership. This model was a self-propelled loader which was launched to the market during 1958. The M-200 Melroe featured a 12.9 HP engine, a 750 lb lift capacity, two independent front drive wheels and a rear caster wheel. By 1960, they replaced the caster wheel together with a rear axle and launched the first 4 wheel skid steer loader that was known as the M-400.
The term "Bobcat" is utilized as a generic term for skid-steer loaders. The M-400 soon after became the Melroe Bobcat. The M-440 version was powered by a 15.5 HP engine and has rated operating capacity of 1100 lbs. The business continued the skid-steer development into the mid 1960s and launched the M600 loader.
Many manufacturers have their own models of the skid steer loader which is just referred to as a Skidsteer in the construction business. Gehl Company, LiuGong, ASV, Hyundai, JCB, Catterpillar, Bobcat, Komatsu, Mustang, John Deere, JLG and New Holland are a few for example, among some.
