A skid-steer loader is an engine powered machinery which consists of a small and rigid frame. It is equipped together with lift arms which are made use of to attach to different labor saving attachments and tools. Normally, skid-steer loaders are four-wheel drive vehicles which have the left-hand side wheels functioning independent of the right-hand side wheels, even though several models are outfitted 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 can carry out zero-radius turns or also called "pirouettes." This added feature enables the skid-steer loader to maneuver for particular applications that require an agile and compact loader.
On a skid-steer loader, the lift arms are at the side of the driver with pivot points at the rear of the driver's shoulders. This makes them different compared to a traditional front loader. Because of the operator's proximity to moving booms, early skid loaders were not as safe as traditional front loaders, specially throughout the operator's entry and exit. Modern skid-steer loaders today have many features to protect the driver including fully-enclosed cabs. Like several front loaders, the skid-steer model can push materials from one site to another, can load material into a trailer or a truck and could carry material in its bucket.
There are a lot of 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 used to excavate the material out of the hole. As the excavation deepens, the machinery reshapes the ramp making it steeper and longer. This is a remarkably useful method for digging under a structure where there is not enough overhead clearance for the boom of a big excavator. For example, this is a common situation when digging a basement beneath an existing house or structure.
The skid-steer loader accessories add much flexibility to the machinery. Like for instance, traditional buckets on the loaders can be replaced accessories powered by their hydraulics consisting of sweepers, mowers, snow blades, cement mixers, pallet forks, backhoes and tree spades. Several other popular specialized buckets and attachments include trenchers, angle booms, dumping hoppers, wood chipper machines, grapples, tillers, stump grinders rippers, wheel saws and snow blades.
During the year 1957, the first front-end, 3-wheeled loader was invented in Rothsay, Minnesota by brothers Louis and Cyril Keller. The brothers invented the loader in order to help a farmer mechanize the process of cleaning turkey manure from his barn. This machine was light and compact and consisted of a rear caster wheel that allowed it to maneuver and turn around within its own length, enabling it to carry out the same jobs as a traditional front-end loader.
In 1958, the Melroe brothers of Melroe Manufacturing Company in Gwinner, N.D. bought the rights to the Keller loader. They hired the Keller brothers to continue refining their loader invention. The M-200 Melroe was the outcome of this particular partnership. This model was a self-propelled loader which was launched to the market during 1958. The M-200 Melroe featured a a 750 lb capacity, two independent front drive wheels, a rear caster wheel and a 12,9 HP engine. By the year 1960, they replaced the caster wheel with a back axle and introduced 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 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 company continued the skid-steer development into the mid nineteen sixties and introduced the M600 loader.
Several manufacturers have their own models of the skid steer loader that is just referred to as a Skidsteer within the construction business. Bobcat, Komatsu, Mustang, john Deere, JLG, New Holland, Gehl Company, LiuGong, ASV, Hyundai, JCB and caterpillar are a few for instance, among others.
