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.
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.
