The engine powered skid-steer loader has a rigid and small frame, outfitted along with lift arms which could attach to several industrial tools and attachments to execute a wide variety of labor saving tasks. Usually, skid-steer loaders are four-wheel drive vehicles that have the left-hand side wheels working independent of the right-hand side wheels, even though several models are equipped 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 what direction the loader would turn.
The skid-steer loader is able to perform zero-radius turns or otherwise called "pirouettes." This added feature enables the skid-steer loader to maneuver for particular applications which require an agile and compact loader.
The lift arms on the skid-steer loader are placed alongside the driver with pivots at the back of the driver's shoulders. These features makes the skid-steer loader different as opposed to the traditional front loader. Because of the operator's proximity to moving booms, early skid loaders were not as safe as traditional front loaders, specially through the operator's exit and entry. Modern skid-steer loaders at present have numerous features to protect the driver like for example fully-enclosed cabs. Similar to various front loaders, the skid-steer model could push materials from one location to another, is capable of loading material into a truck or trailer and could carry material in its bucket.
There are numerous 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 remarkably useful method for digging below a building where there is not enough overhead clearance for the boom of a large excavator. Like for example, this is a common scenario when digging a basement under an existing building or house.
The skid-steer loader attachments add much flexibility to the equipment. 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. Several other popular specialized attachments and buckets comprise wheel saws, snow blades, trenchers, angle booms, dumping hopper, wood chipper machines, grapples, tillers and stump grinders rippers.
In 1957, the first 3-wheeled, front-end loader was invented in Rothsay, in the state of Minnesota by brothers Cyril and Louis 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 compact and light and consisted of a back caster wheel that enabled it to turn around and maneuver within its own length, enabling it to perform the same work as a traditional front-end loader.
The Melroe brothers of Melroe Manufacturing Company in Gwinner, N.D. obtained during 1958, the rights to the Keller loader. The company then hired the Keller brothers to help with development of the loader. The M-200 Melroe was actually the end result of this partnership. This model was a self-propelled loader that was launched to the market during nineteen fifty eight. 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 the year 1960, they replaced the caster wheel with a back axle and launched the very first 4 wheel skid steer loader that was known as the M-400.
The M-400 shortly became the Melroe Bobcat. Often the term "Bobcat" is utilized as a generic term for skid-steer loaders. The M-440 had an 1100 lb rated operating capacity and was powered by a 15.5 HP engine. The business continued the skid-steer development into the mid 1960s and introduced the M600 loader.
Many manufacturers have their own skid-steer loader model simply referred to as Skidsteer within the construction industry. Hyundai, JCB, Caterpillar, Bobcat, Komatsu, Mustang, John Deere, JLG, New Holland, Gehl Company, LiuGong and ASV are some for example, amongst others.
