La minicargadora se asemeja en su función a una pala cargadora, con una gran diferencia: su reducido tamaño. Esta máquina se utiliza principalmente en obras con una superficie de trabajo reducida donde no es rentable o viable utilizar máquinas de mayor tamaño o capacidad, por lo cual es común verlas en ciudades. Su función principal es la carga, transporte y descarga de volúmenes reducidos de material. Se desplaza a una velocidad de 10 km/h aproximadamente. La carga puede realizarla de un montón de material o bajar su cuchara a nivel del suelo y desplazarse frontalmente hasta llenar su cuchara de material suelto. La cuchara puede tener cuchilla o dientes y puede montar martillos hidráulicos o retros de pequeño tamaño en su parte trasera, por lo tanto es una máquina muy versátil, aunque limitada por su escasa potencia. Debido a su distribución de peso esta máquina tiende al vuelco si eleva mucho su cuchara.[cita requerida]
Skid Steer loaders offer great versatility. Due to their compact size and zero-radius turning circle, it is possible to use them in confined spaces where many other types of heavy machinery cannot reach. They are ideal for landscaping in parks and yards, or moving earth around a construction site; and in some cases it is possible to use them in place of a full-scale excavator to dig holes. Sellers on eBay also offer specialized buckets and attachments for clearing snow, grinding tree stumps, mowing grass, or digging trenches. With so many practical applications, skid steer loaders represent an excellent investment for small businesses looking to streamline some of their methods and improve overall workforce efficiency, and they are also useful for homeowners or farmers with a lot of land to maintain.
The conventional bucket of many skid loaders can be replaced with a variety of specialized buckets or attachments, many powered by the loader's hydraulic system. These include backhoe, hydraulic breaker, pallet forks, angle broom, sweeper, auger, mower, snow blower, stump grinder, tree spade, trencher, dumping hopper, pavement miller, ripper, tillers, grapple, tilt, roller, snow blade, wheel saw, cement mixer, and wood chipper machine.
Applications that require the extra horsepower, such as dozing work, are also a good fit for large skid-steer loaders. "Basically, the large-frame skid steers are going to do the heavy lifting for a contractor," says Zupancic. "When they need a big machine to do the hard work on a big site, but they still need maximum manueverablity and versatility, they'll turn to a large skid steer."
Some of the biggest names in the world produce skid steer loaders, including Bobcat, New Holland and Kubota. Consider a Boxer mini skid for domestic and small-scale applications, or invest in a powerful John Deere or Caterpillar loader for commercial use. Even if you choose to buy a second-hand machine, you have the peace of mind that comes from knowing you have bought something built to last.
The original skid-steer loader arms were designed using a hinge at the rear of the machine to pivot the loader arm up into the air in an arc that swings up over the top of the operator. This design tends to limit the usable height to how long the loader arm is and the height of that pivot point. In the raised position the front of the loader arm moves towards the rear of the machine, requiring the operator to move extremely close to or press up against the side of a tall container or other transport vehicle to get the bucket close enough to dump accurately. At the highest arm positions the bucket may overflow the rear of the bucket and spill directly onto the top of the machine's cab.
Jobsite dimensions are one of the greatest factors to know to fit the skid steer to the job. "Understanding physical limitations of the work area often dictates the class that may be used in the application," says Dennis Turney, Hyundai Construction Equipment. "The next consideration would be the lifting height or dumping height requirement, along with the capacity of the job. Finally, hydraulic capacity needs to known in order to operate any hydraulic attachments.

The Melroe brothers, of Melroe Manufacturing Company in Gwinner, North Dakota, purchased the rights to the Keller loader in 1958 and hired the Kellers to continue refining their invention. As a result of this partnership, the M-200 Melroe self-propelled loader was introduced at the end of 1958. It featured two independent front-drive wheels and a rear caster wheel, a 12.9 hp (9.6 kW) engine and a 750-pound (340 kg) lift capacity. Two years later they replaced the caster wheel with a rear axle and introduced the M-400, the first four-wheel, true skid-steer loader. The M-440 was powered by a 15.5 hp (11.6 kW) engine and had an 1,100-pound (500 kg) rated operating capacity. Skid-steer development continued into the mid-1960s with the M600 loader.
