WEM-11/70

The walking excavating machine WEM is designed for digging soil both below and above the natural surface of the ground with the hardness from I to IV category inclusive in the overburden mining production of non-transport circuit with ore laying in worked-out area or on the board of mine face.

The machine can be used in open-cuts in the coal industry, ferrous and nonferrous metallurgy, building materials industry, as well as in the construction of irrigative systems canals and various hydraulic structures.

Low-level pressure ratings on the soil during operation and movement combined with high maneuverability allow the use of machine for the work on soft soils and in space-limited environment.

The distinctive feature of machine electric equipment in comparison with other commercial produced similar excavating machines is the use of asynchronous electric motors with squirrel-cage rotors, which speed control is carried out by means of modular frequency converter with DC common link.
