Import 25 Meters Circular Power Rod Drilling Rig — Buy in wholesale FOB from Supplier in China

The 25 meters crawler rotary pile drilling rig with circular power rod from Shandong Master Machinery Group Co., Ltd. is a hydraulic crawler-mounted foundation machine designed for bored pile construction in sandy clay, silty soil, and rock layers. It features a retractable undercarriage, a self-lifting foldable drill mast, and a telescopic drill pipe system with circular power rod transmission. The main winch uses an imported hydraulic motor with a maximum lifting speed of 82 meters per minute, while the double winching system achieves 100 meters per minute line speed on a single winch configuration. The rig is positioned for large civil engineering, high speed rail, and railway construction projects where penetration through concrete ground, hard sand, and rock is required.

The folding mast structure is built from national inspection-free raw materials, a Chinese designation indicating compliance with mandatory quality standards without batch-level inspection. The upper guide assembly maintains drill pipe perpendicularity to the ground plane, reducing borehole deviation during continuous flight or rotary drilling. The patented power head design emphasizes lubrication reliability and maintenance access, though the source does not specify bearing type, gear ratio, or torque output in kilonewton-meters. The crawler chassis provides transit mobility between bore positions without auxiliary crane support, a typical configuration for urban pile sites with limited laydown area.

Target operators include foundation contractors, rail infrastructure consortia, and large-scale building developers working in mixed soil profiles. The machine's claimed advantages center on drilling speed, fuel economy, and durability in abrasive conditions. Importers should note that concrete ground drilling capability, rock layer penetration, and oil consumption rates are stated as relative advantages without quantitative bench-marking against comparable rigs. All performance claims should be validated through site demonstration or independent test reports before purchase commitment.

Shandong Master Machinery Group Co., Ltd. is located at No. 55 Wutaizha Road, Jining High-Tech Zone, Jining, Shandong Province, postal code 272000. The company holds a harbor trust tier in the available data. Its response rate is recorded at 0.00 percent with zero average response hours, indicating either a new listing, dormant profile, or incomplete metric tracking. The supplier operates from an industrial zone in Jining, a city known for construction machinery manufacturing in northern China.

The company's product focus covers crawler-mounted rotary drilling rigs with emphasis on patented power head designs and imported hydraulic components. No information is provided about factory floor area, annual production capacity, number of employees, or export markets served. The source description references national inspection-free raw materials, a domestic Chinese quality label, but does not cite ISO 9001, CE marking, or other internationally recognized certifications. Buyers should request company registration documents, audited financials, and reference projects to assess production scale and after-sales support capability before committing to a machine purchase.
