Engineered for extreme structural loads, long service life, and high-frequency construction operations worldwide.
Shandong Dazheng International Trade Co., Ltd. is an industry-leading enterprise specializing in the design, manufacture, and global supply of high-end machinery and heavy structural equipment. We are committed to supplying high-performance tower cranes, advanced machinery, and heavy industrial products to engineering firms and contractors worldwide.
Our heavy lifting portfolios, including Topkit (hammerhead), Topless (flat-top), and Luffing Jib tower cranes, are widely used in urban infrastructure projects, chemical complexes, high-rise buildings, and marine transport hubs. In addition to tower cranes, we manufacture specialized agricultural machinery, plate rollers, and metal leveling lines to serve integrated manufacturing and agricultural supply chains.
By implementing strict quality management system protocols, we ensure that every machine leaving our facilities is optimized for peak operational efficiency, wind load structural resistance, and site safety compliance.
Precision engineering supported by state-of-the-art Japanese and European multi-axis CNC machining centers.
Our dedicated manufacturing base spans over 208 acres, with 50,000 square meters of modernized production workshops designed to produce stable, safety-certified structures. To guarantee dimensional tolerances and long-term fatigue resistance, we have built a machining lineup with world-class tool machinery:
This infrastructure allows us to supply critical components for demanding industrial fields, including crane components, structural parts for nuclear power stations, thermal energy generators, hydropower systems, and marine structures.
Collaborative innovation drives safety, structural reliability, and smart operations on high-altitude projects.
Through long-standing partnerships with Tsinghua University and Shandong University, Dazheng integrates theoretical stress analysis and control algorithms into physical tower crane platforms. Our design team applies Finite Element Analysis (FEA) to simulated wind tunnels to ensure safety across our entire range of tower cranes.
Our collaborative dynamic modeling guarantees that stress points on pin joints and slewing assemblies are safely distributed during high-capacity hook movement.
Built-in anti-collision sensors, real-time wind speed meters, and micro-motion positioning systems help crane operators handle loads with millimeter-level accuracy.
We use certified Q345B and Q355B structural steel to maintain durability in sub-zero construction sites and high-humidity maritime regions.
High-performance designs categorized to match specific building shapes and spatial configurations.
Equipped with a classic tower head and tie-bars, the GHT series (e.g., GHT 7032-14, GHT 7050-20) offers structural rigidity and high jib tip load capacities, making them ideal for heavy civil engineering applications.
Flat-top configurations like the GHP7524-16 and GHP8030-20 simplify multi-crane setups in overlapping airspaces. Without a tower head, assembly is faster, and the crane can work safely under high-voltage lines or near airports.
Designed for congested urban high-rises and narrow city blocks. The adjustable jib angle on models like the GHD6090-50 prevents obstruction of surrounding airspace and matches vertical building clearances.
Strategic supply routes, regional engineering support, and import/export compliance for global equipment deliveries.
Dazheng exports cranes and machinery across Europe, North America, Southeast Asia, Central Asia, and Latin America. We help our clients manage transit times and shipping logistics through dedicated services:
We work with international logistics providers to ensure our machinery arrives on schedule, helping you avoid construction delays.
How Dazheng assists global procurement managers in optimizing asset utilization, managing risks, and reducing total cost of ownership.
For global procurement teams, purchasing a tower crane is a long-term capital investment. Our clients balance initial purchase prices with local safety certifications, spare parts availability, and residual market value.
By using energy-efficient frequency-inverter hoisting systems and robust gearboxes, we lower power consumption and reduce motor wear, resulting in lower maintenance costs over time.
Our pin-connected mast sections and modular slewing rings are compatible across several models, allowing fleets to share spare parts and simplify inventory management.
Whether you are managing a high-rise project in Southeast Asia, a shipyard in Northern Europe, or an infrastructure development in Latin America, our cranes are built to handle high-frequency work cycles and varied weather conditions.
