Explore Technical SpecsShandong Dazheng International Trade Co., Ltd. is a leading company specializing in the production and global distribution of heavy industrial machinery and structural equipment. We are committed to providing premium hoisting and heavy fabrication systems to construction projects, agricultural enterprises, and industrial plants worldwide. By balancing raw mechanical power with digital controls, we design solutions that ensure jobsite safety, longevity, and operational cost savings.
Our main products include various types of tower cranes (Topkit, Topless, and Luffing), agricultural machinery, plate rollers, and steel leveling lines. These technologies are widely integrated into high-rise civil construction, power generation infrastructure, heavy metallurgy, and global logistics hubs. By continuously adapting to international engineering norms, we guarantee that our structural assemblies withstand the dynamic stress testing demanded by modern B2B procurers.
Our production plant covers an area of 208 acres, with 50,000 square meters of modern production workshops. To achieve the micro-tolerances required for safe high-altitude crane operations, we have introduced high-end machining stations from leading machinery manufacturers worldwide:
These advanced tools allow us to process core structures for high-grade installations in construction, nuclear power, wind power, marine engineering, and shipyards.
Collaborative academic partnerships driving real-world heavy lifting safety upgrades.
By establishing close technical cooperation with Tsinghua University and Shandong University, we integrate academic research directly into our crane layouts. This cooperation focuses on high-altitude wind resistance and dynamic seismic damping.
Every structural junction, mast connection, and slewing ring undergoes rigorous Finite Element Analysis (FEA). This process minimizes structural fatigue and optimizes load transfers during complex lifts.
We provide full customization, including custom boom configurations, specialized mounting anchors (chassis, tie-in, or traveling bases), and custom paint coatings for high-corrosion environments.
Key technical advancements shaping B2B sourcing and construction engineering globally.
Modern building designs increasingly rely on precast concrete components to speed up construction. Unlike traditional cast-in-place methods, precast construction requires handling heavy, pre-cured structural pieces. This shift has changed the requirements for tower cranes, which now need higher tip load capacities and precise positioning systems. Our Topless and Luffing series are engineered to meet these demands, offering the hook speeds and stable load charts required for modular assembly.
Older direct-on-line starting mechanisms are being replaced by advanced Variable Frequency Drive (VFD) technology. VFDs provide smoother acceleration, reduce electrical loads, and prevent crane swing during trolley movements. Shandong Dazheng integrates modern VFD systems across our entire tower crane catalog, ensuring energy savings and reducing mechanical stress on the gearbox and slewing ring.
In high-density projects where multiple cranes share overlapping areas, collision avoidance systems are essential. Modern tower cranes use integrated sensor systems that monitor boom angle, trolley position, and hook heights in real time. These systems prevent collisions automatically. Our electronic control packages support integration with top anti-collision networks, helping jobsites comply with safety standards worldwide.
Key considerations for procurement officers evaluating long-term equipment purchases.
Initial acquisition cost is only one part of the equation. Critical metrics include power consumption, ease of transport, and assembly times. Our flat-top cranes feature pin-connected structures that simplify assembly and fit into standard shipping containers, reducing logistics costs.
We use certified high-tensile steels (Q355B and Q420B) for our crane structures, ensuring durability in low-temperature environments. Our critical welds undergo non-destructive ultrasonic testing to verify structural integrity before shipping.
Exporting to markets in Europe, North America, Southeast Asia, and Eurasia requires compliance with local standards. Our designs meet international safety guidelines (EN 14439, FEM 1.001, CE, and GOST), easing the local permit approval process.
Optimized field logistics and engineering support across key vertical markets.
Mega-projects like nuclear facilities, hydroelectric dams, and bridge towers require cranes with high load capacities. Our Topkit series, including the GHT 7050-20, provides the hook heights and structural capacity needed to handle heavy machinery and large steel assemblies.
On tight urban jobsites with limited space, topless and luffing cranes are the standard choice. Our Luffing series (such as the GHD6090-50) allows operations in restricted spaces and minimizes over-flight of neighboring properties.
To keep projects on schedule, we provide bilingual technical manuals, foundation loading calculations, and regional engineering support. From pre-sale layout design to on-site assembly guidance, we help resolve technical issues quickly.
Integrating next-generation automation and safety features into our structural systems.
Developing high-efficiency regeneration units that feed brake energy back into the jobsite power grid, reducing fuel and power costs.
Integrating cloud-connected sensor hubs that monitor motor oil conditions, gear wear, and structure stress to support predictive maintenance schedules.
Testing operator-assist control systems that automate repetitive hoist paths, improving cycle times while maintaining high safety standards.
