XCMG XR400E Rotary Drilling Rig

XCMG XR400E Rotary Drill Introduction

The XCMG XR400E rotary drilling rig is a high-performance construction machinery specially designed for cast-in-place concrete pile construction and foundation hole forming operations in building foundation engineering. With its reliable overall performance, this rotary drilling rig is widely applied in the foundation construction of various key infrastructure projects, including ports, highways, railways, bridges, high-rise buildings and urban complexes.

Structurally, the XCMG XR400E is composed of a stable crawler chassis and a professional drilling upper structure, ensuring excellent mobility and operational flexibility on complex construction sites. To adapt to diverse geological layers, it can be equipped with different drilling tools, which work seamlessly with friction or mechanical interlocking Kelly bars, as well as crowd cylinders or crowd winches, to achieve efficient and precise drilling operations.

Equipped with a double swing arm luffing mechanism, the XCMG XR400E not only guarantees outstanding construction stability during high-intensity drilling but also ensures convenient transportation between construction sites, effectively reducing transfer costs. The single-row rope main winch technology is adopted to greatly extend the service life of the steel wire rope, reducing daily maintenance costs for users. Meanwhile, the imported Cummins EFI engine provides strong and stable power output, supporting long-term continuous operation.

In addition, the XCMG XR400E is equipped with extended functions such as casing driving, which further expands its application scope and improves overall construction efficiency. It has become a trusted choice for global construction contractors in medium and large-scale foundation engineering projects due to its durability, efficiency and strong adaptability.

XCMG XR400E Advantages

1.Optimally designed double swing arm luffing mechanism and optimized hinge point position ensure the construction stability and the transport convenience;

2.It adopts dedicated H-style hydraulic retractable crawler chassis for rotary drilling rigs and large diameter slewing bearing, which ensures super stability and transport convenience.

3.Imported Cummins engine ensures strong power and has three-gear power control. Users can choose suitable gears according to working conditions, realizing the three-in-one of the drilling rig. Optimized three-gear power curves effectively reduce the fuel consumption and use costs.

4.The hydraulic system adopts load sensing technology, total power control and limit power control technology, which make the hydraulic system more efficient and energy-saving. It adopts three-in-one combined cooling system with compact structure which has high heat dissipation efficiency.

5.XCMG proprietary main winch with single-row rope effectively solves the twine problem to prolong the service life of wire rope.

6.The rotary drive owns normal mode, rock-entering mode and energy-saving mode. Users can choose suitable modes according to different geological conditions, which improve the construction efficiency and lower the fuel consumption.  

7.Optional configurations such as crowd winch, support leg cylinder and casing driving ensure good expansibility.1.

8.Standard centralized lubrication system makes the maintenance more convenient and improves working reliability.

Max. drilling depth

9、Drilling tools

Long and short auger tools, ordinary drills, sand drilling buckets, and tubular rock drilling buckets can be chosen.

10、Electrical system

The system voltage is 24V, and controller, display, scram button, infrared camera system of main winch, fuse box and power master switch are adopted.

In consideration of the construction technology of rotary drilling rigs, the system adopts CANBUS control technology, integrated circuit technology and CANBUS virtual instrument technology. The human-machine interface is simple for operation and provides automatic real-time display. The PLC control system can automatically/manually adjust the verticality of the drilling mast which is shown in real time and dynamically on the display in the form of “cross” and numerical value, and the pore-forming accuracy can reach 1/400 or above. The drilling depth is automatically detected and displayed in real time, and the drilling depth error is controlled within 1%. There are various security alarms and prompt messages such as drilling mast limit, luffing limit, main winch limit, rocker arm anti-interference system, misoperation alarm, filter alarm and maintenance prompts which can furthest protect the safety of the operator and the machine.
