Rotary Drilling Rig XCMG Xr320 Precision manufactured

Strong power and efficient penetration into rock

Powerful: Equipped with Cummins X12/QSM11 engine, rated power 298–300kW, with a rated torque of 320kN·m for the power head, it boasts outstanding rock-penetrating capability.
Multi-mode: The power head comes standard with five modes: standard, rock penetration, energy-saving, high-speed rock penetration, and high-speed soil removal. It ensures fast drilling in soil layers and stable cutting in hard rocks.
Pressurization and winching: Pressurization force of 250–260kN, pull-out force of 250–370kN; main winch lifting force of 330–340kN, with a single-row rope design, increasing the lifespan of the steel wire rope by over 2 times.

Large pile diameter and deep hole capacity

The maximum drilling diameter is 2500mm (without casing) and 2200mm (with casing).
Maximum drilling depth: 95m for friction rods and 61m for machine lock rods, covering mainstream large pile projects.
Extra-long pressurized stroke: 16m, suitable for construction with long casing and complex strata.

Multi-method and strong adaptability

One machine, multiple functions: It supports mainstream construction methods such as rotary drilling, CFA long spiral, casing drive, down-the-hole hammer, and secant pile.
Reserved interface: Standard pipe-wrapping machine interface, with strong casing construction capability.
Flexible operating conditions: Good adaptability to low clearance and narrow spaces, with convenient transition.

Stability, reliability, and low maintenance

Heavy-duty chassis: With a complete machine weight of 92.8–108t, it features hydraulic telescopic tracks (expanding to 3500–4800mm), heavy-duty slewing bearings, large triangular luffing, and strong anti-overturning capability.
Durable structure: double boom luffing, reinforced drill rod, centralized automatic lubrication, low failure rate.
Convenient maintenance: Centralized arrangement of filter elements and online fault diagnosis reduce downtime.

Intelligent operation and safety

Intelligent system: large-screen display, automatic vertical adjustment of drilling mast, automatic return to vertical, automatic soil throwing, visualized drill rod, automatic cruise.
Safety protection: main winch bottom protection, overload/tilt/turntable locking, real-time verticality monitoring, ensuring high construction accuracy and safety.

Energy-saving and cost advantages

Hydraulic optimization: large displacement and large bore + total power / limit power control, resulting in a 10%–15% reduction in overall fuel consumption.
Lifespan improvement: Single-row rope main winch and floating pre-tensioning significantly extend the lifespan of steel wire ropes and drilling tools.
