XCMG Official Rotary Drilling Rig XR400D.
XR Series Rotary Drilling Rig stands for our company’s achievement in many years’ development and researches on piling machine, adopting the advanced technology, both at home and abroad. With our company’s powerful machinery manufacturing capacity, it is specially designed to drill the pile hole with the big diameter and into hard—layers, fitting for layer conditions in most areas.
XR series is an ideal equipment widely applied in piling constructions, featuring reasonable design, compact structure, convenient operation, high reliability, powerful performance and wide application.
Performance Characteristics:
* It adopts dedicated hydraulic retractable crawler chassis and heavy slewing bearing and has high stability;
* It adopts the luffing mechanism of large triangle form to ensure the stability of construction of big holes and deep piles in hard formation;
* It adopts the front—located single—rope main winch structure to greatly prolong the service life of steel wire rope and lower the use cost;
* Cummins electric control turbo—supercharged engine is used. It complies with Euro Ill emission standard. ln addition, it has strong power, which is sufficient to satisfy the construction on the plateau. Its noise is up to the national standard;
* Using full electronic control technology of CAN bus, improves the reliability of the whole vehicle and simplify hydraulic line, fully reflects the people, machine, electricity and liquid integration;
* Normal mode and entering—rock mode of unit head is available for operation in soil and rock to improve the construction efficiency;
* Winch—pressurized and sleeve—driven functions are available for selection to satisfy various needs of the users;
* It is equipped with a centralized lubrication system as standard configuration; maintenance is easy.
