Hebei Shuangtai Mold Frame Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of adjustable cup-lock base jack in China, featured by quality products and good service. Please rest assured to buy discount adjustable cup-lock base jack from our factory. We also accept customized orders.
Based on over a decade of professional manufacturing experience in cup-lock scaffolding, Hebei Hongxiang's standardized Adjustable Cup-lock Base Jack caters to the needs of domestic housing construction, municipal road and bridge construction, pumped storage, and subway tunnel construction. It also meets export standards for extreme working conditions in Turkey, Côte d'Ivoire, Russia, the UK, and Indonesia. Featuring standardized 38mm solid threaded rods, widened and reinforced base plates, 70μm full-area hot-dip galvanization, and a complete set of bilingual (Chinese and English) certifications, it addresses industry pain points such as incomplete domestic high-support formwork certification data, rapid salt spray corrosion overseas, customs clearance difficulties for non-standard cross-border components, and mismatched scaffolding parameters across multiple countries.
With an annual production capacity of 100,000 tons and local one-stop land transportation and port logistics support, it has become the preferred choice for centralized procurement by domestic central enterprises and for bottom-leveling components in overseas EPC projects, meeting both domestic safety construction needs and overseas long-term cyclical turnover requirements.
Adjustable Cup-lock Base Jack Product Features： First, coaxial homogeneous force transmission. The threaded rods, base plate, and uprights maintain a vertically aligned axis, ensuring the load is vertically downward with no lateral force. Combined with the bottom longitudinal and transverse ground-level bracing, this forms a closed grid, and with the vertical diagonal bracing, it constructs a triangular stability unit. This significantly improves the overall anti-settlement and anti-overturning capabilities of the ultra-high full-span scaffolding, eliminating the risk of structural rejection during supervisory and safety inspections.
Secondly, it features a unified modular design for universal compatibility. The standardized 38mm threaded rods are compatible with all 48-type cup-lock uprights, regardless of upright length. Returned base supports do not need to be sorted by upright specifications; they can be directly transferred across projects, simplifying and streamlining inventory management.
Thirdly, it offers comprehensive and long-lasting corrosion protection. The internal threads of the threaded rods and the weld seams of the base plate are simultaneously galvanized. Even after more than ten years of use in high-humidity underground tunnels, coastal sea salt corrosion, and the open-air environment of the southern rainy season, the threads will not rust or jam, and the base plate weld seams will not corrode or crack. The entire system has been recognized as a green product for formwork and scaffolding.
Fourth, fully automated and unified quality control features： CNC threading, stamping of base plates, automatic double-sided welding, and continuous operation on a closed galvanizing production line ensure consistent precision of the bottom support screws, nut matching, base plate welding strength, and coating thickness within the same batch. Each batch comes with a third-party compressive strength test report, and passes on-site re-inspection on the first attempt.
Adjustable Cup-lock Base Jack Core Advantages： Structural Safety Guarantee： Thickened screws, thickened nuts, and widened and reinforced base plates provide triple pressure protection, with an ultimate bearing capacity far exceeding national standards. Effectively disperses concentrated loads during large-area backfilling and soft soil foundation construction, preventing localized settlement from causing the frame to tilt and collapse. When used in ultra-high formwork exceeding 8m, the frame's stability and safety factor increases by more than 20%.
Advantages of Highly Efficient Foundation Leveling： The trapezoidal thread rotates smoothly, allowing for batch and uniform elevation correction after layout. The horizontal error of the entire scaffold is controlled within 5mm, eliminating the need for repeated shims. Compared to non-standard thin-walled base supports, initial foundation erection time is reduced by 50%, ensuring on-time project delivery and avoiding late payment penalties.
Adaptability to All Working Conditions： Flexible selection for lightweight formwork in ordinary residential buildings, heavy-duty box girders in bridges, underground closed water treatment plants, and overseas factory support. One-stop supply of cup-lock uprights, crossbars, bases, adjustable top supports, and steel treads, eliminating the need for piecemeal procurement from multiple manufacturers.
Compliant Documentation and Acceptance Advantages： Complete material quality assurance certificates, ISO three-system certification, AAA credit enterprise certification, and industry honor documents are provided. Specialized plans for critical engineering projects, safety supervision and inspection documents, and expert review documents are complete, eliminating hidden losses from material parameter non-compliance leading to rejection and rework.
