EDG-8.55
EDG-8.55 crawler dragline is designed on the basis
of
EKG-12 series crawler shovel. It is
intended for stripping in mining industry with availability of loading mineral
products to transport facilities and in construction of large industrial
projects.
The structural features of this model are as follows: boom and tower of lattice
structure made of high-quality steel; triple - tapered bucket; boom-raising
mechanism; motion drive with continues operation mode. The dragline differs with
high mobility during moving. EDG-8.55 provides high unification with
EKG-12
base model. The main mechanisms have direct drive from d.c. motors fed by "generator-motor"
system, static converters controlled on the basis of semiconductor elements and
operational amplifiers.
