WALKING DRAGLINES

Walking draglines

  These are full-revolving crawler-mounted electric-operated earth-moving machines with the working equipment of a dragline type. Draglines are used for opencast mining of mineral resources with no handling facilities during construction of the canals, irrigation and various water-development projects.
  Low soil pressure and high manoeuvrability enable to carry out works on the soft ground and in the confined conditions.
  Draglines are intended to excavate soils of up to the 4th category of hardness inclusive. In this case the soils of the 3rd and 4th category are to be preliminarily loosened by blasting.
