The engine powered skid-steer loader comprises a small and rigid frame, outfitted together with lift arms that can attach to various industrial tools and attachments in order to perform a wide variety of labor saving tasks. Normally, skid-steer loaders are four-wheel drive vehicles which have the left-hand side wheels operating independent of the right-hand side wheels, although various models are equipped along 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 which course the loader would turn.
These equipment are capable of "pirouette" or likewise known as zero-radius turning. This particular feature makes skid-steer loaders very valuable and maneuverable for applications that need an agile and compact loader.
On a skid-steer loader, the lift arms are alongside the driver with pivot points at the back of the driver's shoulders. This makes them different compared to a traditional front loader. Because of the operator's nearness to moving booms, early skid loaders were not as safe as conventional front loaders, especially through the operator's entry and exit. 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 place to another, is capable of loading material into a trailer or a truck and could carry material in its bucket.
There are several times where the skid-steer loader could be utilized in place of a large excavator on the job location for digging holes from within. 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 particularly useful method for digging beneath a structure where there is not enough overhead clearance for the boom of a large excavator. For example, this is a common scenario when digging a basement beneath an existing home or structure.
The skid-steer loader attachments add much flexibility to the equipment. For instance, traditional buckets on the loaders can be replaced attachments powered by their hydraulics consisting of sweepers, mowers, snow blades, cement mixers, pallet forks, backhoes and tree spades. Various other popular specialized attachments and buckets include angle brooms, dumping hoppers, wood chipper machines, grapples, tillers, stump grinders rippers, wheel saws, snow blades, and trenchers.
During 1957, the first front-end, 3-wheeled loader was invented in Rothsay, in the state of 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 particular equipment was compact and light and consisted of a rear caster wheel which enabled it to turn around and maneuver within its own length, allowing it to execute the same work as a conventional front-end loader.
The Melroe brothers of Melroe Manufacturing Company in Gwinner, N.D. purchased in 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 result of this partnership. This model was a self-propelled loader that 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 replaced the caster wheel together with a back axle and launched the first 4 wheel skid steer loader which was known as the M-400.
The term "Bobcat" is used 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 launched the M600 loader.
Many makers have their own models of the skid steer loader that is just called a Skidsteer within the construction trade. Gehl Company, LiuGong, ASV, Hyundai, JCB, Catterpillar, Bobcat, Komatsu, Mustang, John Deere, JLG and New Holland are some for example, among others.
