EDG-4.25
EDG-4.25 and EDG-4.25A crawler draglines are designed on the basis of EKG-5A serial crawler shovel . These models are intended for excavation of mineral products and overburden rock with stacking or loading to transport facilities at open mine workings. The structural features of these models are as follows: separate direct current drive of the main mechanisms of "generator-motor" type; planetary gearboxes of rotary mechanism; motion drive with continues operation mode, lattice boom, triple - tapered bucket  with ground sticking elimination, availability of model with widened crawler belts; swinging laying units and head unit; separate hermetic cab with vibroisolated seat; high unification with EKG-5A base model.
