HPR35A Mini rotary drilling rig offers low clearance and lightweight construction as its core advantages, making it ideal for confined working environments and complex site access requirements.
Engineered for foundation construction, the HPR38-20 is a compact, high-performance mini drilling rig built to excel in confined, low-clearance environments—from under bridges and power lines to indoor construction sites, with zero access barriers.
HPR45-16 mini rotary drilling rig has a maximum drilling depth of 16 metres, with a drilling diameter range of 300 to 1000 millimetres. The machine weighs 12,000 kilograms.
The Straight Auger is a high-performance drilling tool designed for vertical soil excavation in piling operations. Its simple yet robust design makes it ideal for loosening and extracting cohesive soils, sands, and gravel during rotary drilling processes.
Kelly Bar Spring is a precision-engineered elastic component used in rotary drilling rigs to absorb impact and reduce vibration during drilling operations. It plays a vital role in protecting the Kelly bar sections and rotary drive system, ensuring smooth, safe, and efficient pile construction.
Dumping Rubber is a heavy-duty rubber accessory designed to cushion, seal, and protect material discharge areas on construction and mining equipment. It improves efficiency, reduces wear, and prevents material spillage during dumping operations.
A heavy-duty device that rotates and advances casing pipes during drilling or piling operations, ensuring precise alignment and efficient installation. Compatible with various diameters, it enhances productivity in construction, tunneling, and oil/gas applications. Hydraulic or electric-powered for reliable performance.
The Drilling Bucket is a high-performance, heavy-duty attachment designed for efficient excavation and drilling in various soil conditions, including clay, sand, and compacted earth. Engineered for durability and precision, this bucket is ideal for use with excavators, augers, and other drilling machinery in construction, mining, and foundation work.
The single roler bit is composed of a single cone and a lug matched by a bearing.According to different strata and construction requirements, different cutting struclures can be selected; wear resistant carbide are welded and cemented carbide inserts are inserted on the back of the lug. Rotary drilling rig drives the shaft to rotate and exert positive pressure so that the rotary dril- ing bit can impact, roll and shear the rock. Crush the rock to form a crushing ring zone.Then break the middle pillar by the swing of the shaft and take the broken pillar out to form a hole.
Our tremie pipes, crafted from premium drawn steel plates for exceptional durability, feature threaded male-female joints for easy assembly. The standard set includes 4m bottom pipes, 3m standard pipes, and 0.5–2m short pipes. Ideal for bored pile concrete pouring, these pipes are lowered through steel reinforcement cages to deliver concrete precisely, preventing defects like segregation or gaps, shielding concrete from contamination, and ensuring superior pile construction quality.
Our foundation drilling tools are the toughest, strongest, and most durable ones in the construction industry.They are specifically designed for deep hole drilling in construction projects.Our cutting tools are renowned for their exceptional durability and wear resistance.These tools are widely used in the foundational construction of large structures such as buildings, bridges, and towers.
Our pile driver casing is a highly sought-after and long-lasting drilling tool designed for rotary drilling rigs. It meets the technical parameters and processes specified by the high standard, ensuring excellent performance and reliability. The casing joint undergoes a meticulous heat treatment process to control deformation and guarantee accuracy. Each casing section is interchangeable, providing convenience and versatility on the job site.
