In the contemporary landscape of civil engineering and geomechanics, the Rock Portable Point Load Apparatus (PPLA) has transitioned from a niche field tool to a cornerstone of rapid site characterization. As global urbanization demands more complex underground infrastructure—ranging from deep-tier subway systems in London to high-speed rail tunnels across the Himalayas—the need for reliable, "at-source" rock strength data is paramount.
Our PPLA systems provide real-time Point Load Strength Index (Is50) data, allowing engineers to estimate Uniaxial Compressive Strength (UCS) without the delays of laboratory core preparation. This is vital for TBM (Tunnel Boring Machine) optimization and slope stability analysis.
In deep-level mining operations across Australia, Chile, and South Africa, rockburst prevention and pillar design rely on the continuous monitoring of rock hardness. Wholesale PPLA solutions offer a cost-effective way to scale testing across massive concessions.
University labs worldwide utilize our high-precision digital apparatus to study rock anisotropy and the fundamental mechanics of brittle fracture, bridging the gap between theoretical geomechanics and practical field application.
With more than 15 years of civil engineering background, located in the new technology industry development zone in Xi'an, an ancient city in China. It covers an area of 7500 square meters of building area.
We manufacture and supply testing instruments for civil engineering, geological survey, water conservancy and hydropower, roads and bridges, highways, railways and airports. We specialize in the production and sales of geotechnical testing instruments, asphalt and asphalt mixture testing instruments, cement and concrete testing instruments.
Zealchon is engaged in manufacturing and supplying a qualitative array of research and laboratory testing equipment. Another core focus is the semiconductor laser research and development.
Our production workshop features advanced equipment: machining centers, CNC lathes, milling machines, and argon arc welders. This allows for the precision required in the high-pressure hydraulic systems of our Point Load Apparatus.
Founded by experts from Chang'an University, Xi'an Polytechnic University, and Xi'an Petroleum University, we hold the top technology in civil experimental instrumentation research.
Our "Xiya" trademark is a recognized symbol of quality in Shaanxi Province. We have developed core technology instruments that fill domestic gaps and have won multiple national and provincial awards.
Our future development for Rock Portable Point Load Apparatus focuses on three pillars:
Global engineering requires strict adherence to international standards. As a leading Wholesale Rock Portable Point Load Apparatus Supplier, we ensure every unit meets the following criteria:
Compliance with the Standard Test Method for Determination of the Point Load Strength Index of Rock and Application to Rock Strength Classifications.
Aligned with the International Society for Rock Mechanics (ISRM) guidelines for field testing, ensuring data validity for peer-reviewed research.
Full European safety compliance for electronic and hydraulic components, ensuring safe operation in any industrial environment.
Our support team provides localized training materials and remote technical consultations in English, Spanish, and Russian to support our diverse international clientele.
Q: What is the maximum specimen size for the portable apparatus?
A: Most portable units handle specimens up to 100mm in diameter. For larger cores, custom load frames are available upon request.
Q: How do you correlate Point Load Strength (Is) to UCS?
A: The common conversion is UCS = K * Is50, where K is a correlation factor (typically 20-25). However, site-specific calibration is always recommended for maximum accuracy.
Q: Can the apparatus be used on weak rocks?
A: Yes, with a high-resolution digital gauge, the apparatus is sensitive enough to measure the failure points of soft sedimentary rocks and weathered masses.
Q: What maintenance is required for the hydraulic system?
A: Regular oil checks and seal inspections every 6 months are sufficient for most field operations. We provide a full maintenance kit with every wholesale order.
We keep up with national, ministerial, and industry standards. Our production and sales service mechanism ensures products are deeply trusted by global units.
Adhering to "People-oriented, Pursuit of Excellence." Everything we do is based on meeting the unique technical needs of our customers.
We provide "Three Guarantees" for all products sold, backed by a craftsman spirit and professional technical support team.
