A hydraulic rotary drilling rig is a versatile piece of construction equipment designed for creating deep, precise boreholes in various soil and rock formations. It serves as the backbone of modern foundation engineering, enabling the construction of stable structures by drilling holes for concrete piles, caissons, and other foundation elements. These machines excel in projects ranging from high-rise buildings and bridges to solar farm installations and water well drilling.
At YG, we manufacture a robust hydraulic rotary drilling rig that delivers exceptional performance in diverse working conditions. This compact yet powerful small rotary drilling rig combines excellent mobility with high drilling efficiency, making it ideal for both urban job sites with limited space and remote construction areas. It features a maximum drilling depth of 13 meters and supports drilling diameters from 600 mm to 1600 mm, covering the needs of most medium-scale foundation projects. With a walking speed of up to 50 km/h, it can quickly move between different work locations, significantly reducing downtime and improving overall project efficiency.

Pre-Construction Preparation for Rotary Drilling Rigs
- Level and compact the construction site to create a stable working platform for the machine.
- Check all fluid levels, including fuel, hydraulic oil, coolant, and lubricating grease, and top them up if necessary.
- Inspect the drill rod and drill bucket for signs of wear or damage, and replace any worn parts before operation.
- Level the machine and accurately align it with the designated drilling position to ensure precise borehole placement.
- Set up the mud circulation system if using the wet drilling method, which helps remove cuttings and stabilize the borehole walls.
Main Components of a Rotary Drilling Rig
- Chassis and travel system: The heavy-duty chassis forms the structural backbone of the entire machine, while rugged tracks enable smooth movement over rough, uneven terrain and ensure stability during high-torque drilling operations.
- Drilling execution system: This includes the luffing mechanism that adjusts mast angle, the vertical guiding mast, high-torque power head, kelly bar that transfers force to the drill bit, and a durable drill bucket that collects and removes cuttings efficiently.
- Power and hydraulic system: A reliable engine supplies primary power, paired with an advanced hydraulic system that delivers smooth, precise control over all drilling movements and functions.
- Operation and auxiliary system: The enclosed operator cab provides a safe, comfortable workspace with excellent visibility, while the heavy-duty winch system handles lifting and lowering of the drill string and heavy components.
Why do More People Choose YG’s Rotary Drilling Rigs?
- Powerful and consistent drilling performance: Equipped with an 88kW 4108 diesel engine that delivers uninterrupted, steady power, this hydraulic rotary drilling rig easily achieves a maximum drilling depth of 13 meters and a full drilling diameter range of 600-1600mm. It maintains a stable drilling rhythm in clay, sand, and even weathered rock formations, meeting the construction needs of most small and medium-sized foundation projects.
- Efficient and precise hydraulic control system: This rotary drilling equipment features an original CBJT2080 gear pump, with a stable hydraulic system working pressure of 20-25MPa and a displacement of 80ml/r. The power transmission is smooth and responsive, allowing precise control of drill rod speed and feed pressure, which significantly reduces drilling deviation and improves pile verticality and overall quality.
- Flexible site adaptability and transfer capability: With a total weight of 8000kg and a wheelbase of 3150mm, this small rotary drilling rig is paired with a 180-degree full-rotation operation function, enabling flexible work in space-constrained areas such as narrow urban construction sites and residential neighborhoods. Its maximum walking speed of 50km/h allows quick transfer without additional trailers, greatly shortening the interval between projects.
- Durable and easy-to-maintain industrial design: All core load-bearing components are made of high-strength wear-resistant steel, and wearing parts such as drill rods and drill buckets undergo special hardening treatment to extend their service life by more than 30%. The whole machine has a reasonable layout, and all daily inspection and maintenance points are designed in easily accessible positions, allowing a single person to complete routine maintenance, reducing maintenance difficulty and downtime.
FAQ About YG Rotary Drilling Equipment
A: Our rig delivers reliable performance in clay, silt, sand, pebble, weathered rock, strongly weathered rock, and moderately weathered rock (for specific configurations). It is not recommended for hard bedrock or formations with dense, large boulders, as these conditions can cause excessive component wear and reduce operational efficiency.
A: Dry drilling operates without mud circulation, directly extracting soil cuttings from the borehole. This method is cost-effective and fast for stable soil formations where borehole collapse is unlikely. Wet drilling uses a circulating mud system to stabilize borehole walls, cool the drill bit, and carry cuttings to the surface. It is the standard choice for sandy layers, silt, soft soil, and areas with high groundwater levels, where maintaining borehole integrity is critical.
A: Under normal continuous operation conditions, the fuel consumption is about 15-22 liters per hour. The actual fuel consumption will fluctuate according to geological hardness, drilling depth, and operating habits. Our engine adopts optimized fuel injection technology to minimize fuel consumption while ensuring sufficient power.
A: The rotary drilling machine price mainly depends on configuration choices, such as engine brand, hydraulic system configuration, drill rod length and material, as well as whether it is equipped with auxiliary equipment like mud pumps and spare drill buckets. We can provide customized configurations and corresponding detailed quotation solutions based on your specific construction needs.
