The engine powered skid-steer loader comprises a rigid and small frame, equipped with lift arms which could attach to lots of industrial attachments and tools in order to execute various labor saving jobs. Usually, skid-steer loaders are four-wheel drive vehicles which have the left-hand side wheels functioning independent of the right-hand side wheels, though some models are equipped together with tracks instead. On the four-wheel models, having each side independent of each other enables the wheel speed and rotation direction of the wheels to know which course the loader will turn.
The skid-steer loader could carry out zero-radius turns or also called "pirouettes." This added feature allows the skid-steer loader to maneuver for particular applications which need an agile and compact loader.
The lift arms on the skid-steer loader are placed beside the driver with pivots at the rear of the driver's shoulders. These features makes the skid-steer loader different as opposed to the traditional front loader. Due to the operator's nearness to moving booms, early skid loaders were not as safe as conventional front loaders, specially during the operator's entry and exit. Today's' modern skid-steer loaders have numerous features to protect the driver like fully-enclosed cabs. Similar to several front loaders, the skid-steer model could push materials from one site to another, can load material into a truck or trailer and can carry material in its bucket.
There are several times where the skid-steer loader can be utilized instead of a big excavator on the jobsite for digging holes from the inside. To begin, 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 steeper and longer. This is a remarkably functional way for digging under a building where there is not sufficient overhead clearance for the boom of a big excavator. Like for instance, this is a common scenario when digging a basement below an existing structure or house.
The skid-steer loader accessories add much flexibility to the equipment. For example, conventional buckets on the loaders can be replaced attachments powered by their hydraulics comprising snow blades, cement mixers, pallet forks, backhoes, tree spades, sweepers and mowers. Various other popular specialized attachments and buckets consist of tillers, stump grinders rippers, wheel saws, snow blades, trenchers, angle booms, dumping hoppers, wood chipper machines and grapples.
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 process of cleaning turkey manure from his barn. This equipment was compact and light and included a rear caster wheel which allowed it to turn around and maneuver within its own length, enabling it to execute similar jobs as a conventional front-end loader.
The Melroe brothers of Melroe Manufacturing Company in Gwinner, N.D. obtained 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 the end result of this partnership. This particular model was a self-propelled loader which was launched to the market in 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 replaced the caster wheel with a back axle and launched the very first 4 wheel skid steer loader that was referred to as the M-400.
The term "Bobcat" is utilized 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 manufacturers have their own skid-steer loader model just called Skidsteer in the construction industry. John Deere, JLG, New Holland, Gehl Company, LiuGong, ASV, Hyundai, JCB, Caterpillar, Bobcat, Komatsu and Mustang are a few for example, amongst some.
