If you are new to spider excavators, imagine an excavator that can walk, climb, and sit level on steep ground using four independently articulating legs (often with powered wheels). You’ll also hear them called walking excavators. This design spreads ground pressure, protects sensitive sites, and creates a stable work platform where conventional tracked machines can’t safely operate.
The modern spider (walking) excavator took shape in the Alps in the mid-1960s. In 1966, Swiss inventor Ernst Menzi introduced a pioneering machine that left traditional undercarriages behind. Around the same period, Josef (Joseph) Kaiser advanced the concept, with KAISER’s early walking-excavator work dated to 1965. Italian manufacturer Euromach entered the field in 1977, helping establish the category internationally.
By replacing a fixed track/wheelbase with hydraulically adjustable legs (some with powered hubs and quick-fit wheels), the machine can widen its stance, self-level on extreme grades, “walk” or crab over obstacles, and position precisely on riverbeds, boulder fields, or soft ground. Many models add telescoping legs and optional winches for controlled moves on severe slopes.
Alpine contractors needed a way to work safely and with minimal site disturbance on steep slopes, streams, and wetlands—places where standard excavators either slide, exceed safe operating angles, or cause avoidable damage. The spider excavator solves that by combining access, stability, and low ground pressure, reducing risk and environmental footprint while expanding what’s buildable or repairable in hard-to-reach locations.
