Menzi Muck Walking Excavators

Developed in Switzerland by Ernst Menzi and launched in 1966, the Menzi Muck walking excavator has been widely used throughout Europe for decades. The name is derived from a legendary fairy tale character named Muck, who was known as "the little man who does everything."

Until the Menzi Muck was created, there was really no conventional construction equipment that could handle heavy-duty work on slopes and difficult terrain. The Menzi solved an age-old problem of using equipment effectively and efficiently on difficult worksites. 

The key to the Menzi Muck is its unique design that allows each leg or wheel to be raised or lowered, moved in or spread out. This allows the operator to adjust the working base (chassis) to incredible changes in the angles of the terrain. This control of the chassis provides extreme maneuverability and remarkable flexibility, stability and safety in operation. It allows the Menzi Muck to climb and work up, down and across very steep slopes, in five feet of muck and water, in tight spots or in bad weather that mires down other equipment. It also allows the operator to sit comfortably upright, with exceptional 360 degree vision and precise control regardless of the terrain.


The Menzi Muck is the one specialty excavator that provides a solution for the otherwise unsolvable jobs and which outperforms most standard excavators. In working in adverse conditions, time and expense is saved as there is no need for “preparation and restoration” compared to conventional equipment to gain access to work areas.

The walking excavators' special features are based on a sophisticated high-tech chassis and the patented boom: various hydraulic cylinders enable the all-rounder to adapt its wheels and supports to any terrain. For this in some countries the Menzi Muck is also called spider excavator.
