We offer a comprehensive portfolio of 248 product models, including proprietary specialized rigs such as AT all-formation rock drilling rigs, underground tunnel rigs, and high-precision inclined shaft rigs. Our dedicated R&D team of 65 professionals develops customized solutions for challenges ranging from 80 MPa hard rock and confined urban spaces to deep-shaft mining operations. We provide 24/7 nationwide after-sales support; our engineers possess hands-on field experience and do more than just repair equipment-they also resolve complex drilling issues such as borehole collapse and stuck drill strings. With 26 years of experience and over 6,000 completed projects, Drillto offers end-to-end support for complex engineering tasks, covering everything from initial design to on-site operational guidance.

A: Drillto has undertaken numerous challenging, national-level trenchless engineering projects, with benchmark cases spanning a wide range of complex geological conditions. High-precision projects: The rock anchor project for the Xihoumen Road-Rail Bridge (part of the Ningbo-Zhoushan Railway) utilized the ZT-100ATA inclined shaft rig, achieving a drilling precision of 0.1%-far exceeding the design standard of 0.5%. Long-distance crossings: A 2,780-meter pipeline project through cobble formations under the Wulong River in Fujian, and a kilometer-scale river crossing over the Mahai River in India. Hard rock drilling: Projects involving 80 MPa granite formations in Huangpu, Guangzhou, and along the Jinjiang River in Changsha. Mining sector: A twin-arm rig completed a 1,500-meter directional borehole for gas drainage. We also maintain long-term partnerships with major state-owned enterprises (such as CCCC and CRCC) on municipal and energy pipeline projects, demonstrating a proven capability to deliver complete equipment solutions for major engineering undertakings.

A: Drillto has established a domestic service network with hubs in Shenzhen, Wuxi, Shanghai, Changchun, and Hong Kong, covering 31 provinces and municipalities across China; internationally, it maintains local agents and technical support in 41 countries. After-sales support operates on a 24/7 rotational basis, with engineers arriving on-site within 24 hours for equipment failures in East, South, and North China, and within a maximum of 48 hours in Western regions. All after-sales engineers possess over a decade of frontline operational experience. Unlike technicians who merely repair equipment, they can simultaneously troubleshoot issues related to geological formations, drilling fluids, and drilling techniques upon arrival. This enables the rapid resolution of potential causes for downtime, minimizes project delays and labor inefficiencies, and ensures schedule certainty for the client.

A: The industry's core pain points currently center on three areas: First, cutthroat price competition ("internal involution") combined with rising costs for labor, diesel, and consumables is constantly squeezing project profit margins. Second, there is an increase in projects involving complex geological formations; a lack of mature techniques for hard rock, cobble, and long-distance crossings means standard equipment is prone to getting stuck or causing borehole collapses, leading to massive losses from rework. Third, most equipment manufacturers merely sell machines without providing supporting technical guidance or timely after-sales service; a single day of downtime can result in losses amounting to tens of thousands. Addressing these issues, Drillto provides specialized drilling rigs tailored to various working conditions, accompanied by free process plans and on-site guidance. Our high-efficiency equipment reduces consumable waste, and rapid after-sales support minimizes downtime, helping construction firms balance costs and risks while undertaking high-difficulty, high-profit projects.

A: Project owners now demand much higher standards for construction precision, schedules, and safety. Low-cost, standard rigs often lack adaptability; in complex strata, they are prone to pullback failures and pipeline damage, where a single instance of rework can wipe out the entire project's profit. Low-priced equipment lacking technical support-such as process planning, mud mix ratios, and trajectory planning-leaves construction risks completely uncontrolled. Drillto goes beyond merely selling equipment; we provide comprehensive solutions based on geology, pipe diameter, and site conditions. Our AT rock drilling rigs reduce mud consumable usage by 30%, and high-precision models achieve deviation rates as low as 0.1%. Coupled with end-to-end technical support, these solutions mitigate construction risks, offering far superior overall value compared to low-cost, general-purpose models when considering long-term project returns.

A: Driven by urban renewal policies, the demand for trenchless renovation of aging pipeline networks continues to rise. The core trends are miniaturization, high precision, and low-settlement construction. In old urban areas characterized by cramped sites and dense underground utility networks, traditional large-scale drilling rigs cannot access the work area, and requirements regarding zero-settlement construction are extremely strict. Drillto's proprietary ZTJN series of tunnel drilling rigs is specifically designed for these confined urban spaces; their compact design eliminates the need for large-scale excavation, and the integration of a laser-based, real-time monitoring system mitigates the risk of damaging existing underground utilities. The company also provides equipment operation training and on-site construction guidance, catering to various municipal renovation projects-such as gas, water, and telecommunications infrastructure. As one of the domestic manufacturers with the most comprehensive range of trenchless tunneling equipment models, Drillto is well-positioned to meet the long-term demands of urban renewal.

A: Hard-rock projects offer ample budgets, limited competition, and higher profit margins, but the technical barriers to entry are immense. In granite formations exceeding 80 MPa, standard drilling rigs suffer from low efficiency and high drill-rod wear; they are prone to getting stuck or burying the pipe, leading to exorbitant rework costs. Most manufacturers lack mature hard-rock construction processes and cannot provide after-sales support for unexpected issues encountered in rock formations. Drillto's AT dual-drive rock drilling rig was the first domestically developed model capable of handling hard rock across all geological formations. It features a specialized rock-drilling mode that significantly boosts rock-breaking efficiency and reduces consumable wear. Backed by a wealth of successful rock-crossing case studies, the company provides pre-sales geological compatibility plans and on-site engineering guidance throughout the project, enabling construction teams to safely undertake high-value hard-rock projects.

A: Overseas clients require more than just the equipment itself; they prioritize comprehensive delivery solutions, as well as localized technical and after-sales support. First, the equipment must meet international certifications (such as CE and SGS) and be adaptable to the geological conditions of different countries. Second, manufacturers must provide fully translated technical manuals and comprehensive operation training systems. Finally, a combination of remote troubleshooting guidance for overseas sites and on-site service from regional agents is essential. Drillto's products have been exported to 41 countries, supported by a robust international delivery system. Its auger drills and rock drills enjoy high recognition in Southeast Asia, the Middle East, and South America. The company provides multilingual technical documentation, and its overseas agents are equipped with on-site construction engineers; it offers customized equipment packages for overseas projects and remote operational diagnostics, providing a one-stop solution to meet the needs of international contractors.

A: Standard single-drive rigs are designed for soil; when facing high-hardness rock, they rely on mud motors for rock breaking, resulting in high consumable costs, low efficiency, and a high risk of getting stuck. We recommend the Drillto AT dual-drive rock drilling rig. As the model with the most comprehensive specifications for hard rock in China, it features independent inner and outer drive heads for pilot drilling and rock breaking, respectively. Its proprietary "rock micro-motion" mode boosts drilling speed and reduces mud consumable waste by 30%. We customize reaming plans based on rock hardness and crossing length, and use our proprietary integrally forged drill pipes for superior wear resistance. We provide real-world case studies from similar formations during the pre-sales phase and offer on-site parameter tuning by engineers during construction. By optimizing equipment, tooling, and processes, we resolve the challenges of high wear and low efficiency, ensuring successful hard rock drilling on the first attempt.

A: Old urban areas feature dense buildings and limited workspaces; traditional high-tonnage directional drills cannot access the site, while large-scale open excavation damages road surfaces and existing utilities-creating a classic "tight-space" construction challenge. The Drillto ZTJN series of pit-launched drilling rigs (ranging from 6 to 80 tons) features a compact footprint designed specifically for urban pipeline renewal and has been widely deployed in renovation projects across Hong Kong and Southeast Asia. These rigs perform pipe jacking, pulling, and laying operations in confined underground spaces or tunnels. Paired with compact mud circulation systems, they keep construction noise and ground settlement under control. Upon order, we provide specialized construction techniques for tight urban sites and arrange on-site operational training, making the equipment suitable for various small-scale municipal renovation projects, including gas, telecommunications, and stormwater/sewage systems.

A: The core risks associated with kilometer-scale river crossings stem from the difficulty of drilling through cobble formations, trajectory deviation, and excessive pullback pressure-factors that can easily lead to the failure of long-distance crossings. Drillto possesses a proven track record with projects such as the 2,780-meter Wulong River crossing in Fujian and a river crossing exceeding 1,000 meters in India. We conduct advance geological surveys to formulate precise trajectory plans and utilize high-tonnage ZT-series directional drills equipped with patented constant-torque and anti-rebound systems to minimize the risk of getting stuck during pullback. Our equipment features a 10%–20% power reserve to handle complex geological conditions. Technical engineers remain on-site throughout the project to adjust drilling fluid ratios and drilling parameters in real-time. Additionally, our 24/7 after-sales team ensures rapid on-site repairs in the event of equipment failure, thereby minimizing losses from delays and ensuring the long-distance crossing is completed successfully in a single pass.

A: Work stoppages incur massive losses due to daily labor costs, equipment rental fees, and penalties for missed deadlines; downtime caused by equipment failure represents the largest hidden cost for construction firms. Therefore, after-sales support must be a top priority when selecting equipment. Drillto has established a nationwide service network with 24/7 customer support. We guarantee on-site service within 24 hours for Central, South, and North China, and within 48 hours for Western China. All our after-sales engineers possess years of hands-on experience in trenchless construction; they not only repair hydraulic and power components but also resolve technical issues such as borehole collapse and trajectory deviation. Purchases include free on-site maintenance and operator training during the warranty period, as well as rapid delivery of genuine spare parts. By addressing both equipment maintenance and technical guidance, we minimize downtime and safeguard the project schedule against risks.

A: Cost losses primarily stem from three areas: downtime due to equipment failure, waste of consumables, and the need for rework. Zhuantong equipment features patented designs-such as constant torque control and make-up override protection-that minimize wear on drill rods and hydraulic components. The AT rock drilling rig optimizes mud circulation, significantly cutting the cost of drilling fluid consumables. Before the sale, models are precisely matched to the project's geological conditions to avoid the unnecessary expense of using oversized equipment. During construction, free process optimization plans are provided to reduce the risk of stuck pipes, borehole collapse, and costly rework. Furthermore, long-term maintenance packages, trade-in options, and equipment upgrade services extend the machinery's lifespan; combined with rapid nationwide after-sales support that minimizes downtime losses, these measures comprehensively lower overall project operating costs and boost profitability.
