Skidsteers

A skid-steer loader is a compact, rigid-frame construction machine equipped with a front-mounted hydraulic lift arm and a wide range of interchangeable attachments. It steers by varying the drive power to the left and right sides, causing the vehicle to skid or pivot in place. This differential braking or drive control allows extremely tight turning radii, enabling operation in confined spaces. Although commonly used with a bucket, many attachments are compatible through a universal mounting plate or quick-attach system.

Power, drive, and attachments: Most skid-steers are diesel-powered and available with rubber tires or steel tracks. They use a hydraulic system to operate the lift arms, drive motors, and attachments. Common attachments include buckets, pallet forks, grapples, bale clamps, breakers, augers, trenchers, snow blowers, and sweepers. The quick-attach coupler enables rapid tool changes, enhancing versatility for multiple tasks on job sites.

Operation and safety: Operators control drive and implement functions through joysticks or two-lever controls. Training and familiarity with controls, load limits, and terrain are essential for safe operation. Typical safety features include rollover protective structures (ROPS), falling object protective structures (FOPS) on appropriate models, seat belts, audible backup alarms, lighting, and interlocks that prevent operation without the operator in the seat.

History and use: The skid-steer concept originated in the late 1950s from inventors in North America, notably the Keller brothers, who developed the differential braking steering method. The Melroe manufacturing company popularized the design, with later models marketed under the Bobcat brand. Today, skid-steers are widely used in construction, landscaping, farming, and material handling due to their maneuverability, compact size, and versatility. Limitations include relatively limited load-carrying capacity for their size and stability concerns on uneven or sloped terrain.
