The engine powered skid-steer loader consists of a rigid and small frame, equipped along with lift arms that could attach to lots of industrial tools and attachments to execute many labor saving jobs. Normally, skid-steer loaders are four-wheel drive vehicles that have the left-hand side wheels functioning independent of the right-hand side wheels, although various models are equipped along 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 determine what course the loader will turn.
These machines can "pirouette" or zero-radius turning. This particular feature makes skid-steer loaders very valuable and maneuverable for applications that require an agile and compact loader.
The lift arms on the skid-steer loader are situated next to the driver with pivots at the rear of the driver's shoulders. These features makes the skid-steer loader different compared to the traditional front loader. Because of the operator's nearness to moving booms, early skid loaders were not as safe as traditional front loaders, particularly throughout the operator's exit and entry. Today's' modern skid-steer loaders have many features to be able to protect the driver like for example fully-enclosed cabs. Similar to various front loaders, the skid-steer model could 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 lots of times where the skid-steer loader can be used instead of a large excavator on the job location 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 machinery reshapes the ramp making it steeper and longer. This is a very useful way 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 situation when digging a basement below an existing house or building.
There is much flexibility in the attachments that the skid steer loaders are capable of. Like for example, the conventional bucket of many of these loaders can be replaced with many 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 comprise trenchers, angle booms, dumping hoppers, wood chipper machines, grapples, tillers, stump grinders rippers, wheel saws and snow blades.
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 made this machinery in order to help mechanize the process of cleaning in turkey barns. This machinery was compact and light and had a back caster wheel that enabled it to turn around and maneuver within its own length, enabling it to carry out the same jobs as a conventional front-end loader.
The Melroe brothers of Melroe Manufacturing Company in Gwinner, N.D. obtained in the year 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 the outcome of this partnership. This particular model was a self-propelled loader that was introduced to the market during the year 1958. The M-200 Melroe featured a two independent front drive wheels, a rear caster wheel, a 12.9 HP engine and a 750 lb lift capacity. By the year 1960, they replaced the caster wheel along with a back axle and launched the very 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 shortly 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 launched the M600 loader.
Various manufacturers have their own skid-steer loader model just known as Skidsteer within the construction industry. Gehl Company, LiuGong, ASV, Hyundai, JCB, Catterpillar, Bobcat, Komatsu, Mustang, John Deere, JLG and New Holland are a few for instance, among others.
