XR400E

XCMG XR400E rotary drilling rig performance characteristics: 1. Optimize the design of the double-boom luffing mechanism, optimize the position of the hinge point, and take into account the stability of construction and the convenience of transfer transportation; 2, the use of rotary drilling rig dedicated H-type hydraulic telescopic crawler chassis, equipped with large diameter slewing bearings, to ensure a strong stability and transportation convenience; 3. Imported Cummins engine is adopted with strong power and three-speed power control. Users can select corresponding gears according to working conditions to realize the function of three engines in one drilling rig. Optimized three-speed power curve. Load sensing technology is adopted for the hydraulic system, and total power control and limit power control technology are superimposed to make the hydraulic system more efficient and energy-saving. The three-in-one radiator system is adopted with compact structure and high heat dissipation efficiency; 5. XCMG's proprietary single-row rope main hoisting structure effectively solves the problem of wire rope "biting rope" and greatly prolongs the service life of wire rope; 6, the power head has a normal mode, into the rock mode and energy-saving mode, the user can choose the corresponding mode according to different geological conditions, improve the construction efficiency and reduce fuel consumption; 7. Multiple configurations: optional winch pressurization, chassis leg oil cylinder, casing drive, etc., with good expansibility; 8, standard centralized lubrication system, maintenance more convenient, improve work reliability.
