Description of Crawler Excavator (Crawler Digger)
A crawler excavator (crawler digger) is a designed vehicle to dig or move large objects. It is widely used in construction work, such as digging of trenches, holes, foundations; handling material, moving earth, demolition, dredging, etc. Many other attachments are always adopted to crawler excavator (crawler digger) for boring, ripping, crushing, cutting, lifting, and so on. We supply crawler excavator (crawler digger) of mini excavator, medium crawler excavator (crawler digger) and swamp buggy excavator from 1.6 ton to 44 ton operating weight range and equipped with world-class components. For amphibious excavator, we offer range from 0.2 to 1.1 m3 bucket swamp buggies, with operating reach from 9 meters to 15.5 meters. We adapts original imported Cummins engine, or original imported Mitsubishi engine, as well as original imported Korea hydraulic elements, original imported Kawasaki pump, original imported TOSHIBA or Parker valve and motor. The especially long boom and the wide vision cabin is designed for it. All those ensure it to be suitable for hydro-electric project, mining, road construction, city dwellings construction, pipe laying, dredging project and road repair projects.
