A skid-steer loader is an engine powered equipment that has a small and rigid frame. It is outfitted together with lift arms which are used to attach to different labor saving attachments and tools. Typically, skid-steer loaders are four-wheel drive vehicles that have the left-hand side wheels operating independent of the right-hand side wheels, even if various models are equipped 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.
The skid-steer loader is able to perform zero-radius turns or likewise called "pirouettes." This added feature enables the skid-steer loader to be able to maneuver for particular applications that require a compact and agile loader.
On a skid-steer loader, the lift arms are at the side of the driver together with pivot points at the back of the driver's shoulders. This makes them different than a conventional front loader. Because of the operator's nearness to moving booms, early skid loaders were not as safe as traditional front loaders, particularly in the operator's exit and entry. Modern skid-steer loaders today have many features to protect the driver like for example fully-enclosed cabs. Similar to several front loaders, the skid-steer model could push materials from one site to another, is capable of loading material into a truck or trailer and could carry material in its bucket.
There are lots of times where the skid-steer loader can be used instead of a large excavator on the job location for digging holes from the inside. To begin, the loader digs a ramp to be utilized to excavate the material out of the hole. As the excavation deepens, the machine reshapes the ramp making it steeper and longer. This is a very helpful method for digging under a structure where there is not sufficient overhead clearance for the boom of a large excavator. Like for instance, this is a common scenario when digging a basement beneath an existing building or home.
There is much flexibility in the attachments that the skid steer loaders are capable of. Like for instance, the conventional bucket of many of these loaders could be replaced with numerous attachments which are powered by the loader's hydraulic system, including pallet forks, backhoes, tree spades, sweepers, mowers, snow blades and cement mixers. Some other popular specialized buckets and attachments consist of angle brooms, dumping hoppers, wood chipper machines, grapples, tillers, stump grinders rippers, wheel saws, snow blades, and trenchers.
The 3-wheeled front end loader was invented in the year 1957, by Louis and Cyril Keller in their hometown of Rothsay, in the state of Minnesota. The Keller brothers made this machine to help mechanize the method of cleaning in turkey barns. This particular equipment was compact and light and included a back caster wheel which allowed it to maneuver and turn around within its own length, allowing it to execute similar jobs as a traditional front-end loader.
In 1958, the Melroe brothers of Melroe Manufacturing Company in Gwinner, N.D. purchased the rights to the Keller loader. They hired the Keller brothers to continue refining their loader invention. The M-200 Melroe was the result of this partnership. This particular model was a self-propelled loader which was launched to the market in 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 1960, they changed the caster wheel along with a rear axle and introduced the very first 4 wheel skid steer loader that 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 has rated operating capacity of 1100 lbs powered by a 15.5 HP engine. The business continued the skid-steer development into the middle part of the 1960s and introduced the M600 loader.
Several makers have their own models of the skid steer loader which is just called a Skidsteer in the construction business. John Deere, JLG, New Holland, Gehl Company, LiuGong, ASV, Hyundai, JCB, Caterpillar, Bobcat, Komatsu and Mustang are a few for instance, amongst some.
