Los ergonómicos controles hidráulicos por piloto proporcionan un control preciso con un mínimo esfuerzo. La palanca universal derecha controla las funciones de levantamiento, bajada e inclinación del cargador, mientras que la palanca universal izquierda controla la velocidad de desplazamiento de avance y de retroceso, y los cambios de sentido. Las palancas universales especiales optativas proporcionan controles auxiliares adicionales que permiten controlar con la punta de los dedos muchas funciones de las herramientas, incluidas las funciones hidráulicas proporcionales y las funciones eléctricas proporcionales. Las funciones de las palancas universales básicas y especiales incluyen el flujo hidráulico auxiliar continuo y el flujo hidráulico auxiliar momentáneo con un solo toque.
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.
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."
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.
No over-digging. No undercutting. No wasted time, fuel or dollars. SiteControl helps eliminate rework by making reliable, repeatable precision a reality. CASE offers tailor-made hardware and software solutions for all positioning and measuring tasks in construction, including ways for businesses to improve productivity and lower costs – both on and off your machine.
The wheels on a skid steer typically have no steering mechanism, they are in a fixed, straight line relative to the body of the machine. By turning the left and right wheel pairs at different speeds, the machine turns by skidding, or dragging its wheels across the ground. The rigid frame and strong wheel bearings prevent the torsional forces caused by this dragging motion from damaging the machine. This skidding motion tears up the ground on which the machine operates.
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]
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 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.
