YG Rotary Drilling Equipment Components
Excellent engineering requires reliable power distribution. Maximum structural efficiency relies on a matched power-to-hydraulic ratio. The rig is equipped with a high-torque 4108 engine model delivering 88 kW of power, purpose-built for continuous soil penetration. The hydraulic rotary drilling rig consists of several core components working together:
- Strong chassis and crawler or wheel-type walking units.
- Heavy-duty mast and stable luffing mechanisms.
- Dynamic power head and flexible telescopic kelly bars.
- Efficient drilling buckets and strong hoisting systems.
- Comfortable operation cab with clean electrical controls.
Versatile Soil Adaptation Using Rotary Water Well Drilling Rig
By adopting high-torque mechanical logic similar to professional deep water well systems, this equipment adapts to diverse geological strata via interchangeable tooling:
The system adapts to multiple soil and rock categories easily:
- Clay and silt layers: Recommended configuration with specialized drilling buckets featuring heavy-duty teeth to slice through cohesive clay without suction locking.
- Pebbles and weathered rock: Easily handles tougher obstacles using rock core barrels or reinforced spiral augers to fracture formations.
YG Rotary Drilling Rig Machine Types
- Small-Sized Piling Rigs: These compact machines feature a torque of 100-120 kN·m and an engine power of 100-170 kW. With a drilling diameter of 0.5-1.5m and depths up to 40-45m, their total mass ranges from 35-40 tons, making them ideal for slope protection and small municipal projects.
- Medium-Sized Piling Rigs: A standard medium-size rotary drilling rig machine provides around 180 kN·m of torque and a 200 kW engine. Weighing roughly 65 tons, it achieves a drilling depth of 60m and diameters of 0.8-1.8m, which perfectly fits high-speed railway bridge piers and large building foundations.
- Large-Sized Piling Rigs: Designed for extreme environments, these giants offer a torque above 240 kN·m and engine power over 300 kW. They drill up to 80m deep with diameters of 1-2.5m, have a total mass exceeding 100 tons, and tackle mega-bridges or specialized deep structures.
Friction Kelly Rigs and Interlocking Kelly Rigs
| Operation Method | Similar to the operation logic of excavators. No unlocking is required during drilling, with a simple workflow. Drill lifting and lowering are smooth without jamming. | Reverse rotation unlocking is required for each drill lifting, with a dedicated unlocking method. The unlocking difficulty increases with the number of extended kelly bar sections during deep drilling. |
| Construction Parameters | Maximum drilling depth of 30 meters, maximum borehole diameter of 1.5 meters. High drilling speed, up to 1 meter per minute at peak performance. | Drilling depth of 30-60 meters, maximum borehole diameter of 2.6 meters for dual-power head models. High drilling pressure but relatively slow drilling speed. |
| Geological Adaptability | Only suitable for soft/loose formations such as soil layers, pebble layers, and strongly weathered rock layers, including clay layers, fill layers, and silt layers. | In addition to soft formations, it can handle moderately weathered rock and even harder geology, with wider adaptability. |
| Cost & Price | Low purchase cost: the 135 model for drilling within 15 meters is priced at approximately 230,000 RMB, with relatively low transportation and maintenance costs. | Starting price of 350,000 RMB (for drilling within 15 meters); the price of deep drilling models can reach millions of RMB, with an overall cost much higher than that of square kelly bar rigs. |
| Pressurization Principle | Pressurization relies on the friction between kelly bar sections, and the bottom hole pressure is limited by the friction force. | Pressurization is realized through the platform on the kelly bar key. 4 sections of kelly bar can support full pressurization drilling, with strong drilling capacity in hard formations. |
Frequently Asked Questions (FAQ)
A1: Interlocking kelly bars have mechanical locks that provide stronger downward pressure, which makes them ideal for drilling into hard rock layers. Friction kelly bars transfer pressure through friction, allowing them to drill faster and reach greater depths in soft soils and sand layers.
A2: Our standard configuration includes three matching drilling tools based on your job requirements. You can choose from spiral drills, standard drilling buckets, or rock core barrels to perfectly match your local ground conditions.
A3: This hydraulic equipment can drill to a maximum depth of 13 meters. It supports an adjustable drilling diameter ranging from 600 mm up to 1600 mm, which covers most civil engineering and building foundation needs.
A4: Yes. Any model with a maximum drilling depth under 25 meters can be loaded and transported easily inside standard 40-foot high cube (40HQ) shipping containers, keeping your international shipping costs low and safe.
A5: Daily maintenance includes checking oil levels, water coolant, and electrical connections.
