El único motor (de gasolina o diésel) de esta máquina suele estar acoplado en la parte trasera, en el punto de unión entre los brazos de la cuchara y el chasis. Cuenta con un sistema hidráulico para la elevación de la cuchara o para permitir el montaje de otros accesorios. El chasis se desplaza sobre un sistema de orugas o de neumáticos, siendo más habitual este último con una distribución de cuatro neumáticos de igual diámetro repartidos equitativamente a los lados.[cita requerida]
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]

An extended reach design uses multiple hinges and parallel lifting bars on the loader arm, with the main pivot points towards the center or front of the machine. This allows the loader arm to have much greater operating height while retaining a compact design, and allows the vertical movement to be less of an arc and more straight-up vertical, to keep the bucket forward of the operator's cab, allowing safe dumping into tall containers or vehicles.
United Rentals offers you the world’s largest fleet of dependable skid-steer loaders. From the farm to the construction site to the industrial plant, these compact and maneuverable machines are ready to tackle your jobs fast and cost-effectively. Skid-steers are excellent for digging, grading and leveling. The larger machines are suited for the toughest applications and for use with special high-performance high-flow hydraulic attachments. A wide variety of attachments allow each of these machines to do more than just load materials. Quick-change attachment systems give you the ability to quickly and easily connect attachments.
Zupancic says it's all about the size of the site and the use the skid steer is put to. "These construction and jobsite applications require a little more power and bucket size, but are still in a confined enough space that contractors cannot bring in the big machines," he explains. "Sometimes the operator doesn't need the extra muscle of a larger skid-steer loader and finds it more economical to have a 50- to 70-hp machine."
Las herramientas pueden cambiarse rápida y fácilmente con el sistema de acoplador rápido de la máquina. El acoplador rápido estándar permite el acoplamiento y desacoplamiento manual de las herramientas utilizando dos palancas de alto efecto de apalancamiento. El acoplador rápido hidráulico optativo permite al operador cambiar rápidamente las herramientas sin salir de la cabina.
Los aceleradores manual y de pedal permiten al operador acoplar la velocidad del motor a la tarea que se va a realizar. El acelerador manual es ideal para trabajos que requieren velocidad constante del motor, como el perfilamiento de pavimento en frío, la apertura de zanjas o el soplado de nieve. El acelerador de pedal permite al operador variar la velocidad del motor y disminuir al mínimo el consumo de combustible en otras tareas, como las de carga y acarreo, carga de camiones, nivelación y explanación.
Who likes dropping or spilling materials? No one. That’s why CASE’s innovative Ride Control™ feature is such a benefit. Just push a button to automatically steady the loader arm when traveling at elevated speeds and the machine automatically compensates with greater shock absorption and reduced loader arm bounce, so you can work faster than ever without spilling your load.

Skid-steer loaders are typically four-wheel vehicles with the wheels mechanically locked in synchronization on each side, and where the left-side drive wheels can be driven independently of the right-side drive wheels. The wheels typically have no separate steering mechanism and hold a fixed straight alignment on the body of the machine. Turning is accomplished by differential steering, in which the left and right wheel pairs are operated at different speeds, and the machine turns by skidding or dragging its fixed-orientation wheels across the ground. The extremely rigid frame and strong wheel bearings prevent the torsional forces caused by this dragging motion from damaging the machine. As with tracked vehicles, the high ground friction produced by skid steers can rip up soft or fragile road surfaces. They can be converted to low ground friction by using specially designed wheels such as the Mecanum wheel. Skid-steer loaders are capable of zero-radius, "pirouette" turning, which makes them extremely maneuverable and valuable for applications that require a compact, agile loader. Skid-steer loaders are sometimes equipped with tracks instead of the wheels, and such a vehicle is known as a multi-terrain loader.[1]

This machine size's ROC allows it to lift the heaviest loads, such as moving pallets of brick or dumping loads of dirt into the back of trucks. "These machines also have the horsepower and hydraulic flow to tackle tough jobs and attachments," says Rostberg. "Attachments that perform best with a high-flow machine, such as a wheel saw or planer for road construction or a forestry cutter for site preparation, work best with these machines."
Indicadores del sistema de alarma para el operador: restricción del filtro de aire, salida del alternador, posabrazos levantado/operador fuera del asiento, temperatura del refrigerante del motor, presión del aceite de motor, activación de las bujías, restricción del filtro hidráulico, temperatura del aceite hidráulico, freno de estacionamiento conectado
"Interior demolition is a good example where these machines excel, as the machine is small enough to access the inside of a building, yet powerful enough to use a hydraulic breaker attachment to demolish concrete and then switch to a grapple to remove the debris," says Rostberg. "Accessing in-between houses built closely together or through backyard gates and fences is another prime example of the usefulness of this size machine."

El sistema contra calado aumenta al máximo la potencia de la máquina permanentemente, haciendo coincidir el par motor con los requisitos de operación del sistema hidrostático y del sistema del implemento. Esta característica de detección de carga evita que el motor se cale, aun durante la operación a acelerador parcial, lo que mantiene la productividad alta y el consumo de combustible bajo.
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.
A skid-steer loader can sometimes be used in place of a large excavator by digging a hole from the inside. The skid loader first digs a ramp leading to the edge of the desired excavation. It then uses the ramp to carry material out of the hole. The skid loader reshapes the ramp making it steeper and longer as the excavation deepens. This method is particularly useful for digging under a structure where overhead clearance does not allow for the boom of a large excavator, such as digging a basement under an existing house. Several companies make backhoe attachments for skid-steers. These are more effective for digging in a small area than the method above and can work in the same environments. Other applications may consist of transporting raw material around a job site, or assisting in the rough grading process.

The first three-wheeled, front-end loader was invented by brothers Cyril and Louis Keller in Rothsay, Minnesota, in 1957.[2] The Kellers built the loader to help a farmer, Eddie Velo, mechanize the process of cleaning turkey manure from his barn. The light and compact machine, with its rear caster wheel, was able to turn around within its own length, while performing the same tasks as a conventional front-end loader.[2]

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."
