The engine powered skid-steer loader consists of a small and rigid frame, outfitted with lift arms that could connect to various industrial attachments and tools so as to carry out many 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, though some 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 know what course the loader would turn.
The skid-steer loader can carry out zero-radius turns or also called "pirouettes." This added feature allows the skid-steer loader to be able to maneuver for particular applications which need a compact and agile loader.
The lift arms on the skid-steer loader are situated alongside the driver along with pivots behind the driver's shoulders. These features makes the skid-steer loader different compared to the traditional front loader. Due to the operator's proximity to moving booms, early skid loaders were not as safe as traditional front loaders, especially in the operator's exit and entry. Today's' modern skid-steer loaders have many features to protect the driver including fully-enclosed cabs. Like various front loaders, the skid-steer model can push materials from one site to another, is capable of loading material into a trailer or a truck and can carry material in its bucket.
There are various times where the skid-steer loader could be utilized rather than a big excavator on the jobsite for digging holes from within. To start, 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 remarkably helpful way for digging beneath a structure where there is not adequate overhead clearance for the boom of a large excavator. For example, this is a common scenario when digging a basement below an existing house or structure.
There is much flexibility in the accessories which the skid steer loaders are capable of. For example, the traditional bucket of many of these loaders could 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. Various other popular specialized buckets and attachments consist of wood chipper machines, grapples, tillers, stump grinder rippers, wheel saws, snow blades, trenchers, angle booms and dumping hoppers.
The front end 3-wheeled loader was invented during 1957, by Louis and Cyril Keller in their hometown of Rothsay, in the state of Minnesota. The Keller brothers created this equipment to help mechanize the method of cleaning in turkey barns. This particular machine 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 execute the same jobs as a conventional front-end loader.
In the year 1958, the Melroe brothers of Melroe Manufacturing Company in Gwinner, N.D. bought the rights to the Keller loader. They employed the Keller brothers to continue refining their loader invention. The M-200 Melroe was actually the end result of this particular partnership. This model was a self-propelled loader which was introduced to the market during the year 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 changed the caster wheel with a back axle and launched the very first 4 wheel skid steer loader which was referred to as the M-400.
The term "Bobcat" is used as a generic term for skid-steer loaders. The M-400 immediately 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.
Several makers have their own skid-steer loader model just known as Skidsteer in the construction business. Gehl Company, LiuGong, ASV, Hyundai, JCB, Catterpillar, Bobcat, Komatsu, Mustang, John Deere, JLG and New Holland are some for instance, amongst others.
