The engine powered skid-steer loader consists of a small and rigid frame, outfitted with lift arms which can connect to various industrial attachments and tools to execute various labor saving jobs. Usually, skid-steer loaders are four-wheel drive vehicles which have the left-hand side wheels operating independent of the right-hand side wheels, even if some models are outfitted together 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 know what course the loader would turn.
These equipment are capable of "pirouette" or otherwise known as zero-radius turning. This feature makes skid-steer loaders very maneuverable and valuable for applications that need a compact and agile loader.
On a skid-steer loader, the lift arms are at the side of the driver with pivot points at the back of the driver's shoulders. This makes them different compared 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, especially during the operator's exit and entry. Modern skid-steer loaders at present have many features to be able to protect the driver like for example fully-enclosed cabs. Like 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 can carry material in its bucket.
Many times a skid-steer loader is able to be used on a jobsite rather than a big excavator by digging a hole from within. To begin with, the skid-steer loader digs a ramp leading to the edge of the desired excavation, and then it makes use of the ramp to be able to excavate material out of the hole. As the excavation deepens, the equipment reshapes the ramp making it longer and steeper. This is a particularly helpful way for digging beneath a structure where there is not adequate overhead clearance for the boom of a large excavator. Like for example, this is a common situation when digging a basement underneath an existing structure or house.
There is much flexibility in the accessories that the skid steer loaders are capable of. For instance, the conventional bucket of many of these loaders can be replaced with many attachments which are powered by the loader's hydraulic system, consisting of tree spades, sweepers, mowers, snow blades, cement mixers, pallet forks and backhoes. Some other popular specialized attachments and buckets comprise tillers, stump grinders rippers, wheel saws, snow blades, trenchers, angle booms, dumping hoppers, wood chipper machines and grapples.
In nineteen fifty seven, the first 3-wheeled, front-end loader was invented in Rothsay, Minnesota by brothers Cyril and Louis Keller. The brothers invented the loader in order to help a farmer mechanize the process of cleaning turkey manure from his barn. This equipment was compact and light and had a back caster wheel that enabled it to maneuver and turn around within its own length, allowing it to perform the same work as a conventional front-end loader.
The Melroe brothers of Melroe Manufacturing Company in Gwinner, N.D. purchased during 1958, the rights to the Keller loader. The business then employed the Keller brothers to help with development of the loader. The M-200 Melroe was actually the end result of this particular partnership. This particular model was a self-propelled loader which was introduced to the market during nineteen fifty eight. 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 the year 1960, they changed the caster wheel along with a rear axle and launched the very first 4 wheel skid steer loader that was referred to as the M-400.
The term "Bobcat" is used 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 middle part of the nineteen sixties and launched the M600 loader.
Various makers have their own models of the skid steer loader which is just referred to as a Skidsteer within the construction industry. Hyundai, JCB, Caterpillar, Bobcat, Komatsu, Mustang, John Deere, JLG, New Holland, Gehl Company, LiuGong and ASV are a few for instance, amongst others.
