50-Meter Rotary Drilling Rig – High-Efficiency Pile Foundation Construction Equipment for Deep Foundation Engineering

Overview

The 50-meter rotary drilling rig is a professional hydraulic pile foundation construction machine engineered for deep foundation drilling tasks in large-scale construction projects, including high-rise buildings, bridges, dams, ports, and industrial facilities. As a core piece of equipment for foundation engineering, it integrates a high-torque drilling system, stable crawler chassis, and intelligent control system to deliver efficient, precise, and reliable drilling performance in diverse soil conditions—from soft clay and sand to hard rock and weathered rock formations.

Built to international CE/ISO 9001 standards with heavy-duty components and a modular design, this drilling rig is optimized for continuous operation in harsh construction environments. It features a maximum drilling depth of 50 meters and a maximum drilling diameter of 2500mm, making it suitable for a wide range of pile foundation types (bored piles, rock-socketed piles, diaphragm walls). As a factory-direct product, it offers customizable configurations, easy maintenance, and long service life, making it the preferred choice for construction contractors, foundation engineering companies, and infrastructure developers worldwide.

Core Features & Advantages

1. Unmatched Drilling Performance & Efficiency

50m Max Drilling Depth & 2500mm Max Diameter: Engineered to handle deep foundation drilling tasks for high-rise buildings and large bridges, with a drilling depth of up to 50 meters and a maximum diameter of 2500mm—covering most foundation engineering requirements.
High-Torque Drilling System: Equipped with a 300–500 kN·m high-torque hydraulic drilling motor and a heavy-duty drill pipe, delivering strong drilling power to penetrate hard rock and weathered rock formations efficiently. The variable-speed drilling function (0–120 rpm) adapts to different soil conditions for optimal drilling efficiency.
Fast Drilling Cycle: Optimized drill pipe design and automatic rod handling system reduce the time for rod adding/removing by 30% compared to manual operation, with a fast drilling speed of up to 800 mm/min in soft soil—maximizing construction progress.
Multiple Drilling Modes: Supports rotary drilling, casing drilling, and core drilling modes, compatible with various drill bits (bucket drill, core drill, cross drill) to handle different soil and rock types.

2. Stable Crawler Chassis & High Mobility

Reinforced Crawler Chassis: 3.0m-wide heavy-duty crawler tracks with a reinforced frame, distributing the machine’s weight evenly to minimize ground pressure (≤0.28 MPa). The chassis provides exceptional stability during high-depth drilling and heavy-load operation, even on uneven construction sites.
Hydraulic Outriggers & Leveling System: Four hydraulic outriggers with automatic leveling function ensure the rig is quickly and accurately leveled (within ±1°) in complex terrain, preventing tilting during drilling and improving drilling precision.
Excellent Maneuverability: Dual high-torque track motors with a maximum travel speed of 4.5 km/h, enabling easy movement and repositioning on large construction sites. The compact design allows navigation in narrow spaces for urban foundation projects.

3. Durable Design for Harsh Working Conditions

Heat & Dust Resistant Engineering:
- Engine compartment with a high-efficiency cooling system (radiator + oil cooler) and a large-capacity fan, operational at ambient temperatures up to 50°C—preventing overheating during continuous operation.
- Sealed hydraulic and electrical systems with IP65 dust-proof/waterproof rating and high-efficiency air filters, protecting internal components from dust, sand, and water ingress in construction environments.
Wear-Resistant Components: Drill pipe and drill bits are made of high-strength alloy steel with surface hardening treatment, improving wear resistance and extending service life by 25%. The crawler pads are made of wear-resistant rubber for long-term use on rough terrain.
Corrosion-Resistant Coating: Multi-layer anti-rust system (zinc-rich primer + epoxy topcoat) on all steel structures, protecting against corrosion in humid or rainy construction environments.

4. Intelligent Operation & Enhanced Safety

Ergonomic Operator Cab: Spacious, soundproof cab with air conditioning, adjustable seat, and a vibration-dampened system. The 10-inch touchscreen display (multi-language support) provides real-time monitoring of drilling depth, torque, speed, and hydraulic pressure, with automatic fault diagnosis and alarm functions.
Intelligent Control System: Equipped with a PLC-based intelligent control system, supporting automatic drilling, automatic rod handling, and remote monitoring (optional). The system records drilling data (depth, diameter, soil type) for quality control and project management.
Comprehensive Safety Protections:
- Overload Protection: Auto-shuts down the drilling system when exceeding rated torque or load to prevent equipment damage.
- Drill Pipe Anti-Drop System: Mechanical and hydraulic double anti-drop protection to prevent drill pipe falling during operation, ensuring operator safety.
- Emergency Stop System: Hardwired emergency stop buttons in the cab and on the machine body for instant shutdown in critical situations.
- ROPS/FOPS-Certified Cab: Reinforced cab structure to protect the operator in case of rollover or falling objects.

5. Customizable Configurations for Project Flexibility

Drilling Depth & Diameter Options: Customize drilling depth up to 60 meters or drilling diameter up to 3000mm for special foundation projects (e.g., super high-rise buildings, large dams).
Drill Pipe & Bit Customization: Choose from different types of drill pipes (kelly bar, friction drill pipe) and drill bits (bucket drill, core drill, rock drill) based on soil and rock conditions.
Power System Options:
- Diesel Engine: 350–450 HP 6-cylinder high-power diesel engine (Cummins/Weichai) compliant with EU Stage IIIA/IV emission standards, offering low fuel consumption and high reliability.
- Electric Motor: Optional 300kW high-voltage electric motor for zero-emission operation in urban areas or indoor construction sites.
Additional Accessories: Optional casing oscillator for casing drilling in loose soil, mud pump for slurry circulation, and a dust collection system for environmentally friendly operation.
