HPR35 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.

HM-14 Fully Hydraulic Multi-Functional Drilling Rig

The HM-14 full-hydraulic multifunctional ground improvement equipment is designed for small-section tunnels and coal mine roadways.

Vibroflot

The Vibroflot operates on the principle of vibration compaction. Its high-power vibrator generates high-frequency vibrations, which are transmitted to soil particles. Under the influence of these vibrations, loose soil particles rearrange themselves, reducing voids and significantly enhancing soil density and bearing capacity. Additionally, the built-in water flushing system assists in loosening the soil during operation, enabling the vibrator to penetrate deeper into the soil layers and further optimizing treatment results. Whether dealing with sandy soil, silty soil, or other liquefiable soils, the Vibroflot efficiently reinforces the soil, effectively preventing foundation settlement and providing a solid and stable base for superstructures.

Mixing Plant

A mixing plant is a facility that combines raw materials like aggregates (sand, gravel), cement/bitumen, and water to produce construction materials such as concrete or asphalt for road building and other projects, with types ranging from large stationary setups for massive projects to mobile units for temporary or remote sites, focused on efficiency, quality, and precise material ratios.

HP200 High-Pressure Pump

The high-pressure pump commonly used in engineering construction is easy to operate and has a unique structural design for quick disassembly and maintenance. This equipment possesses characteristics such as ultra-high pressure, high efficiency and stable.

Diaphragm Wall Grab

APIE AHG Series Hydraulic Grab is a product developed and designed based on decades of experience in diaphragm wall construction and equip-ment development in China.It addresses various issues encountered with similar equipment during construction, adapting to complex geological conditions both domestically and internationally.This helps reduce customer usage costs and create value for clients.

Kelly bar spring

Short Description:

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.

Product Detail

Our Kelly Bar Springs are designed for use with interlocking or friction-type Kelly bars on rotary drilling rigs. These heavy-duty springs are mounted between Kelly bar sections or between the rotary head and the Kelly box to absorb the shock loads generated during drilling and casing operations.

Made from high-strength spring steel and heat-treated for durability, these springs enhance equipment lifespan and reduce the risk of mechanical damage in heavy-duty piling applications.

Applications:

Rotary drilling rigs (Soilmec, Bauer, SANY, XCMG, Zoomlion, etc.)
Interlocking Kelly bars
Friction Kelly bars
Casing drive systems
Shock-absorbing connection between rotary drive and drilling tool
