Trenchless Equipment & Construction Solutions For Complex Underground Engineering

 One of China's largest HDD rig manufacturers by production volume and sales, and a core driver of trenchless technology localization.
 Top-3 national market share for 26 consecutive years; ranked No.1 in national sales for 15 consecutive years at its peak (assessed by the Trenchless Technology Committee of the China Geological Society).
 Peak year 2015: approx. 29% domestic market share and about 10% of the international market.
 ZT series HDD rig market share: 20.8% (2019), 23.6% (2020), 24.8% (2021).
 Named among China's "Top 50 Specialized Construction Machinery Manufacturers" (China Construction Machinery magazine, 2024).

 248 models across seven series, covering HDD rigs from 6 t to 1,200 t - the industry's smallest to largest units - for soil, sand and soft-rock strata.
 China's most complete trenchless product line: standard machines, special-purpose rigs and fully customized units.
 End-to-end coverage of trenchless scenarios: micro units to super-large tonnage, soil strata to hard rock, standard to bespoke.
 The only leading domestic manufacturer that develops main machines and integral forged drill pipes in-house in sync.

 258 patents filed, including 38 granted invention patents, targeting real construction pain points.
 AT all-strata rock drilling rigs use a dual power-head structure whose inner drill pipe delivers torque and rotation directly, replacing traditional mud motors - lower mud consumption, greener operation and higher steering accuracy for one-pass hard-rock drilling.
 Laser while-drilling monitoring replaces conventional steering tools, enabling ultra-high-precision inclined drilling (demonstrated end-hole accuracy of 0.1%).
 Patented systems: constant-torque control, anti-rebound protection, make-up over-torque protection, dual-motor three-speed dynamic switching, and a dedicated rock-drilling mode.
 Power & control: Cummins diesel engines (diesel series) and leading-brand electric motors (electric series); internationally top-tier hydraulic components; a 10–20% power reserve by default; CAN-bus control with a Danfoss controller and 7-inch display.

 International: CE (2007), SGS (2023), ISO 9001 (2008), ISO 14001 (2011), ISO 45001 (2022), ISO 50001 (2022).
 National: National High-Tech Enterprise (2010); National "Little Giant" Enterprise (2025); Ministry of Land and Resources Science & Technology First Prize (2013).
 Provincial: Jiangsu Non-Excavation Equipment Engineering Technology Research Center (2010); Guangdong Trenchless Directional Drilling Engineering Technology Research Center (2023); Jiangsu Industrial Design Center (2023); Jiangsu Green Factory (2025).
 Industry recognition: "Top 50 Specialized Construction Machinery Manufacturers" (2024); Jiangsu "Purple Gold Award" Design Competition Excellence Award (2024); China Staff Technical Innovation Award (2024); International Society for Trenchless Technology special contribution award (2009–2010).
 Compliance: work-safety standardization, "Five-Star Cloud" digitalization, and IP management system certification.

 Founder & Chairman Wang Peng: professor-level senior engineer; member of the Trenchless Technology Committee of the China Geological Society; a pioneer and core driver of HDD technology localization in China with nearly 30 years of experience. He led China's first guided-drilling trenchless pilot-hole project in 1993, received the "HDD Excellence Contribution Award" at the 50th anniversary of HDD technology (2021), and was recognized as an industry leader in a CCTV interview (2023).
 65-strong R&D and engineering team (45 R&D specialists + 20 engineering staff); 90% hold bachelor's degrees or above; 60% hold mid-to-senior professional titles; expertise spans drilling engineering, mechanical & electronic engineering, geological engineering, electrical engineering and mechanical design.
 Academic partnership: postgraduate innovation base of China University of Geosciences (Wuhan), with 3 tenured university professors engaged.

 Domestic network: covers all 31 provinces, municipalities and autonomous regions of China, with service stations in Shenzhen, Hong Kong, Wuxi, Changchun and Shanghai.
 Overseas agents: South Korea, Russia, Kazakhstan, the Philippines, India, Bangladesh, Brazil, Saudi Arabia and Iraq - covering Southeast Asia, Central Asia, the Middle East and South America.
 Response commitment: 7×24 on-call support; on-site arrival within 24 hours in East, Central and North China, and within 48 hours at most in West China.
 Engineering-grade service team: all service engineers have 10+ years of frontline trenchless construction experience and resolve equipment faults and geology/mud/process issues in a single visit.
 "Project Downtime Risk Protection" system: pre-sales scheme design, on-site operation training and 7×24 after-sales support that protect construction schedules end to end.

 Ultra-high-precision rock anchor holes, Zhoushan Cross-Sea Bridge: end-hole accuracy of 0.1%.
 Xihoumen Bridge, Yongzhou (Ningbo–Zhoushan) Railway: the world's largest rock-anchored bridge anchor; 72 anchor holes with inclination deviation controlled to 0.1%, well within the 0.5% design requirement, drilled with the ZT-100ATA inclined drilling rig.
 80 MPa hard-rock crossings: Guangzhou Huangpu (320 m), Changsha Jinjiang River (440 m), and Guangzhou Panyu multi-pipe rock works.
 Long-distance crossings: Wulong River, Fujian - a 2,780 m crossing through pebble strata; and a kilometer-class crossing on the Mahai River in India.
 Deep-mine gas drainage: 1,500 m+ single-hole directional drilling with dual-arm high-torque rigs.
 China's first kilometer-class horizontal directional coring rig: jointly developed with CRCC Heavy Industry and certified at internationally leading level by the National Construction & Building Machinery Quality Supervision & Inspection Center.
