XCMG XR280E Rotary Drilling Rig Product Introduction

As a new-generation large-tonnage product of the E-series rotary drilling rigs, the XR280E is upgraded and upgraded based on the mature XR280D model, a classic product in our company’s construction machinery lineup. To further enhance construction efficiency, this large-tonnage rotary drilling rig has increased power output and optimized system flow, which can effectively shorten the construction cycle and improve the overall construction efficiency of foundation engineering, bringing more competitive advantages to global contractors.

Focusing on operational stability and long-term reliability—core demands of heavy-duty foundation construction—the XR280E rotary drilling rig adopts a full set of optimized large-scale structural components. These key components include a slewing platform with an I-beam structure (high load-bearing capacity and strong stability), a double jib parallelogram luffing mechanism (smooth amplitude adjustment and high precision), a segmented thick-plate drilling mast (strong anti-deformation ability and long service life), and a vertical pin type power head bracket (stable power transmission and low failure rate). These professional structural designs comprehensively improve the equipment’s adaptability to high-intensity construction and reduce subsequent maintenance costs.

With its excellent comprehensive performance, the XR280E rotary drilling rig is widely applied in foundation construction projects of various large and medium-sized infrastructure, including ports, docks, highways, railways, bridges, high-rise buildings and urban complex projects. In practical construction, it can be flexibly equipped with mechanical interlocking or friction Kelly bars, and cooperate with different types of rotary buckets (such as sand drilling buckets, tubular drills and short spiral drills) to adapt to diverse geological conditions. At the same time, it supports CFA (continuous flight auger) or dual rotary drive working modes, which further expands its application scope and meets the diverse needs of global foundation construction.

XCMG XR280E Highlights

1.One machine with multiple functions, can achieve quick switching of functions such as oil cylinder pressurization, winch pressurization, pipe rolling machine, long screw, dual power head, etc., to meet the needs of more different engineering construction projects.

2.Adopting a specialized H-shaped hydraulic telescopic track chassis for rotary drilling rigs, equipped with large-diameter rotary bearings, ensuring strong stability and convenient transportation.

3.Optimized design of dual arm variable amplitude mechanism, optimized hinge point position, balancing construction stability and convenient transfer transportation.

4.Both the main and auxiliary winches adopt single row rope technology, and the service life of the steel wire rope is 2-4 times longer than that of multi-layer ropes, with lower operating costs.

5.Equipped with a Volvo electronically controlled turbocharged engine for greater power, stronger power, and lower fuel consumption.

6.The pressure system adopts load sensing technology, combined with total power control and limit power control technology, to improve the efficiency and energy saving of the hydraulic system. It adopts an independent radiator system, which has high heat dissipation efficiency.

7.Multi gear power head and dual motor single row rope main winch improve working performance by 20%, resulting in higher operating efficiency.

8.The intelligent control system realizes functions such as automatic adjustment and display of the verticality of the drilling mast, automatic rotation, automatic soil throwing, automatic lifting and pouring of the long spiral construction method, and pile type display. It adopts a bus panel design to effectively prevent misoperation.
