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.
The C-14 full-hydraulic multifunctional ground improvement equipment is designed for small-section tunnels and coal mine roadways. It integrates drilling, water stopping, drainage, and grouting functions. With a full-hydraulic drive system, it adapts well to complex environments and enables multi-angle operations (vertical, horizontal, inclined). Its intuitive interface allows quick parameter adjustment even in narrow spaces, enhancing efficiency and safety in underground projects. It is an ideal solution for ground reinforcement and hydrological control in mines and tunnels.
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.
Extended-range electric dynamic compaction crane is an electric dynamic compaction product launched proactively by APIE in line with the national strategy and the market demand. the Eextended-range electric dynamic compaction crane is more eficient, reliable and intelligent while maintaining lower consumption.
ASC series mainly serves the mud purification treatment in trenchless construction, The comprehensive treatment of cyclone and shale shaker is used to separate the mud particles, reduce the sand content of the mud, so that the mud can be recycled. It has the advantages of saving the cost of mud making, meeting the requirements of construction grouting, and reducing environmental pollution.AsC series desander can be matched with the construction equipment includes horizontal directional drilling rig, pipe jacking machine, etc.
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.
