High-end hoisting, redirection, and structural support modules designed to sustain peak structural loads under critical drilling conditions.
Offshore drilling platforms, including semi-submersibles and drillships, encounter violent wave actions and harsh marine environments. The heavy-duty equipment support structures on these vessels must manage dynamic hook loads while compensating for heave and sway. Components like forged steel sheaves and auxiliary sheave assemblies redirect high-tension wire ropes continuously, preventing fatigue failure and ensuring smooth operations under continuous cyclical stress.
Onshore extended-reach drilling (ERD) projects demand high torque and tension to push and pull drill strings through miles of horizontal sections. The drawworks and crown blocks bear the brunt of these intense forces. Heavy-duty support systems prevent structural deflection, ensuring that the mast and substructure remain aligned, which directly protects the drill string and casing from premature failure.
Established on July 15, 2003, and headquartered in Baoji City, Shaanxi Province—sharing the same cradle of petroleum technology with BOMCO—MTPM is a leading manufacturer of premium petroleum machinery and components. We were among the first outstanding enterprises in our local industry to begin exporting our products, engaging in both import and export businesses globally.
For over two decades, we have dedicated ourselves to manufacturing high-quality petroleum machinery and supplying reliable products and technical services to drilling companies and oilfield equipment traders worldwide. Our products are engineered to provide maximum support for heavy-duty drilling rigs, ensuring seamless operations in the most demanding environments.

Operating a drilling rig for heavy-duty rig equipment support presents a myriad of mechanical and metallurgical challenges. The primary concern is structural fatigue. When a drilling rig is pulling thousands of meters of heavy drill pipe out of the hole (tripping out), the crown block, sheaves, and drawworks experience massive tensile loads. If the sheaves are not perfectly balanced or if the steel alloy lacks the necessary toughness, micro-cracks can develop, leading to catastrophic failure.
MTPM addresses these challenges through advanced manufacturing processes. Our heavy-duty sheaves, ranging up to 1524mm in diameter, are forged from premium structural steel and heat-treated to optimize hardness profile and wear resistance. Forging refines the grain structure of the steel, making it significantly more resilient to impact loads and fatigue compared to cast alternatives. The groove profiles of our sheaves are flame-hardened or induction-hardened to prevent wire rope wear, ensuring both the sheave and the wire rope have an extended operational life.
Since 2014, MTPM has maintained strict compliance with API standards. Our products carry the prestigious API Monograms:
In the global drilling industry, speed of component replacement is critical. MTPM specializes in manufacturing 100% interchangeable components for top-tier drilling equipment brands, including BOMCO, HONGHUA, RG, LANSHI (LSNOV), and DFXK. This ensures that operators can source premium replacement parts without modifying their existing rigs, significantly reducing lead times and maintenance costs.

As the drilling industry strives for net-zero carbon emissions and higher efficiency, the technology behind drilling rig for heavy-duty rig equipment support is undergoing a massive shift. The integration of AI, IoT sensors, and real-time monitoring systems is transforming passive mechanical components into smart, interactive assets. For instance, modern drawworks and mud pumps are being equipped with vibration and temperature sensors that feed data directly to edge-computing units on the rig, enabling predictive maintenance and preventing catastrophic failures before they occur.
Furthermore, electrification is replacing traditional hydraulic and diesel-mechanical drives. Electric drawworks and high-pressure mud pumps (such as the F800HL series) deliver precise control over speed and torque, leading to smoother hoisting operations and more consistent mud flow. The structural components supporting these systems must adapt to handle rapid acceleration and deceleration cycles. By utilizing optimized metallurgical compositions and advanced structural designs, manufacturers like MTPM ensure that the crown blocks and auxiliary sheaves can absorb these dynamic energy spikes without compromising structural integrity.
Modern auxiliary sheave assemblies are engineered to minimize wire rope friction and wear. By optimizing the groove geometry and utilizing self-lubricating bearings, these assemblies reduce the energy required for wire rope redirection, contributing to overall rig efficiency and extending the service life of high-cost wire ropes.
Heavy-duty mud pumps require robust structural support to handle high-pressure pulsations. MTPM's API-7K certified components are engineered to withstand pressures up to 5000-7500 PSI, ensuring continuous, reliable mud circulation critical for wellbore stability and efficient cuttings removal.
We collaborate with major oilfield service companies and equipment manufacturers globally to ensure reliable operations.
