XR280C

FEATURE

Equiped with the chassis (CAT336D) ensures high reliability, and heavy duty hydraulic retractable tracks are used to make easy transportation; Imported CAT C9 STH 261Kw@1800RPM engine, meeting EPA Tier III emission standards; Negative flow control, superimposed on the total power control and ultimate power control are used to make hydraulic systems more efficient and more energy-efficient; The single rope main winch effectively solve the problem of the “rope bite the rope” and greatly extending the service life of wire rope; Drill rod of high-performance multi-configuration, meeting the requirements both from the hard layer and ultra-deep pile hole construction, maximum drilling depth: 88 meters; A variety of configurations: rotary drill mast to stand up automatically, casing drive, and good scalability; The standard centralized lubrication system makes the maintenance more convenient and reliability.
