The engine powered skid-steer loader consists of a rigid and small frame, outfitted with lift arms that can connect to numerous industrial attachments and tools in order to execute several labor saving tasks. Usually, skid-steer loaders are four-wheel drive vehicles which have the left-hand side wheels operating independent of the right-hand side wheels, though various models are outfitted along with tracks instead. On the four-wheel models, having each side independent of each other allows the rotation direction of the wheels and the wheel speed to determine what course the loader will turn.
The skid-steer loader could execute zero-radius turns or otherwise called "pirouettes." This added feature enables the skid-steer loader to be able to maneuver for particular applications that 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 traditional front loader. Because of the operator's proximity to moving booms, early skid loaders were not as safe as conventional front loaders, especially all through the operator's exit and entry. Today's' modern skid-steer loaders have various features in order to protect the driver like for instance fully-enclosed cabs. Similar to other front loaders, the skid-steer model can push materials from one site to another, is capable of loading material into a truck or trailer and could carry material in its bucket.
There are many times where the skid-steer loader can be used rather than a big excavator on the jobsite for digging holes from the inside. To begin, the loader digs a ramp to be utilized to excavate the material out of the hole. As the excavation deepens, the equipment reshapes the ramp making it steeper and longer. This is a very useful way for digging underneath a building where there is not sufficient overhead clearance for the boom of a large excavator. For instance, this is a common situation when digging a basement underneath an existing home or structure.
There is much flexibility in the attachments which the skid steer loaders are capable of. For instance, the conventional bucket of many of these loaders can be replaced with various attachments which are powered by the loader's hydraulic system, consisting of pallet forks, backhoes, tree spades, sweepers, mowers, snow blades and cement mixers. Several other popular specialized attachments and buckets consist of tillers, stump grinders rippers, wheel saws, snow blades, trenchers, angle booms, dumping hoppers, wood chipper machines and grapples.
In 1957, the first front-end, 3-wheeled loader was invented in Rothsay, 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 machinery was light and compact and had a back caster wheel which allowed it to maneuver and turn around within its own length, enabling it to execute similar tasks as a conventional front-end loader.
In the year 1958, the Melroe brothers of Melroe Manufacturing Company in Gwinner, N.D. acquired the rights to the Keller loader. They hired the Keller brothers to continue refining their loader invention. The M-200 Melroe was the end result of this partnership. This particular model was a self-propelled loader that was introduced to the market during 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 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 shortly after became the Melroe Bobcat. The M-440 version has rated operating capacity of 1100 lbs powered by a 15.5 HP engine. The company continued the skid-steer development into the middle part of the nineteen sixties and introduced the M600 loader.
A lot of manufacturers have their own skid-steer loader model simply known as Skidsteer within the construction trade. Bobcat, Komatsu, Mustang, john Deere, JLG, New Holland, Gehl Company, LiuGong, ASV, Hyundai, JCB and caterpillar are some for example, among others.
