YDL-600DX Crawler Water Well Drilling Rig with 7m Stroke and 600m Depth Capacity

YDL-600DX Crawler Water Well Drilling Rig with 7m Stroke and 600m Depth Capacity

The YDL-600DX is a high-performance, fully hydraulic crawler-mounted drilling rig designed for deep water well drilling, geological exploration, foundation anchoring, geothermal drilling, and various rotary and percussive drilling methods. Engineered with an impressive 7-meter stroke feed system and equipped with a powerful hydraulic motor, high-lift oil cylinders, and a high-pressure DTH hammer, the rig delivers outstanding penetration efficiency, wide adaptability, and low operating cost.

Key Features

1. Powerful Drilling Capability

The YDL-600DX offers strong penetration performance with a maximum drilling depth of 600 meters and a borehole diameter range from Φ150 to Φ450mm. Its powerful hydraulic system, large torque output, and strong lifting/pushing force allow it to handle complex geology and multi-layered formations with ease.

2. 7-Meter Long Stroke for Enhanced Efficiency

The rig is equipped with an internal/external telescopic mast allowing a total power head stroke of 7 meters, enabling it to drill with two 3-meter drill rods in a single feed. This significantly reduces the rod-adding time and doubles the drilling efficiency.

3. High-Torque Dual-Speed Rotary Head

With a maximum output torque of 18,000 Nm, the rotary head supports mechanical and hydraulic dual-speed adjustment, offering a wide range of rotation speeds:

• Infinitely variable: 0–25 rpm

• Fixed gear speeds: 3 / 25 / 41 / 50 / 56 / 97 / 120 rpm
  This flexibility allows the rig to adapt to various drilling techniques, including:

• DTH hammer drilling

• Casing drilling

• Full casing drilling

• Rotary drag bit drilling

• Air/mud circulation drilling

4. Advanced Feed and Extraction System

The hydraulic feed cylinders offer up to 12.8 tons of thrust and 30 tons of pullback force, ensuring steady progress in deep or tough formations. The stroke of the feed cylinder is 3.5 meters, and the power head stroke is 7 meters, giving the rig superior control in both fast and precise operations.

5. Efficient Hydraulic Clamping and Shock Absorption

The spindle integrates a telescopic cushioning mechanism, which effectively protects drill rods and tool joints, especially during make-up and break-out operations. This reduces wear on threads and improves equipment longevity.

6. Excellent Mobility and On-Site Flexibility

Mounted on a crawler undercarriage, the rig offers smooth site transfer with a travel speed of 1.5 km/h and a 25° climbing capacity. The rig includes four long-stroke hydraulic outriggers, which make it possible to load/unload from trucks without a crane—simplifying logistics and reducing auxiliary costs.

7. Heavy-Duty Tool Winch

Equipped with a 2-ton tool hoist, the rig enables quick and safe lifting of rods, casing, and accessories.

• Lifting speed: 15 m/min

• Steel rope: Ø9.3mm, 40m capacity

8. Flexible Operation and Structure

• Drilling angle adjustable from 0° to 90°, enabling vertical or inclined hole drilling.

• Minimum ground clearance: 250mm

• Hydraulic rotary chassis with positioning pins for enhanced drilling stability and adaptability.

9. Premium Hydraulic System

The hydraulic control system adopts top-quality domestic and imported components, ensuring:

• Long service life

• Stable performance

• Minimal maintenance downtime

10. Compatible with Multiple Drilling Techniques

The YDL-600DX is capable of handling a wide range of drilling technologies:

• Dry auger drilling

• High-pressure air DTH drilling

• Mud rotary full casing drilling

• Air hammer with casing advancement

• Tricone bit rotary drilling

This versatility makes it suitable for:

• Deep water wells

• Foundation pile holes

• Anti-floating and tie-back anchors

• Soil stabilization and grouting
