Dynamic stability XCMG XR280E Rotary Drilling Rig

Characteristics of Power System

Equipped with Cummins high-power turbocharged engine, it has sufficient power reserve and supports continuous high-altitude operation. The hydraulic system adopts load sensing and constant power control, and the power head comes with three modes: normal mode, rock entry mode, and energy-saving mode. The torque output is stable, and there is no need for repeated debugging when switching between soft and hard layers. The main winch adopts a single row steel wire rope layout to reduce wire rope wear and extend service life.

Chassis and structural characteristics

Equipped with a dedicated telescopic track chassis, it has a large grounding area after deployment, sufficient self weight of the whole machine, and strong anti overturning ability during construction; The width after contraction is compliant, and the flatbed truck can be directly transported without splitting the tracks, resulting in high transfer efficiency. Large diameter slewing support, strong rigidity of mast, uniform force distribution of pressurized structure, and low deformation during long-term deep hole operation. Standard centralized automatic lubrication, easy maintenance of the pivot and rotating parts.

Characteristics of Construction Control

Equipped with an intelligent construction monitoring system, it displays torque, pressure, drilling depth, and verticality in real time, and comes with dynamic mast correction. The verticality of the drilled hole can be stably controlled within 0.3%. Supports dual pressurization of winch and oil cylinder, and can be equipped with a pipe rolling machine, long spiral, and down the hole hammer. One machine is suitable for various pile foundation construction methods.

Characteristics of working condition adaptation

The standard drilling diameter is 2.5m, and the maximum drilling depth can reach 87-94 meters. It can not only complete the pile foundation of high-rise buildings, but also undertake the foundation of bridges and high-speed railway piers; It has sufficient pressure and torque to deal with pebble layers and moderately weathered rock layers, and has strong rock penetration ability. It is not easy to work continuously for a long time at high temperatures and hold up vehicles.
