Industrial-grade configurations engineered for maximum hook height, stability, and variable load capacities.
Modern mega-infrastructure projects require lifting equipment that balances high hoist speeds with structural safety. Global general contractors and heavy lifting fleet managers often turn to standards set by industry leaders like Liebherr Tower Cranes. These machines represent the global benchmark for finite element structural optimization, variable-frequency slewing drives, and control intelligence. However, as supply chain backlogs grow and project costs rise, international procurement directors are looking for qualified global suppliers who design and manufacture tower cranes to matching international standards, such as FEM 1.001 and EN 14439.
Shandong Dazheng International Trade Co., Ltd. operates at the intersection of precision engineering and global logistics. By combining advanced manufacturing machinery with structural design practices verified in cooperation with elite research institutions like Tsinghua University and Shandong University, our industrial fleet offers reliable alternatives for high-load projects worldwide.
"Procurement directors do not just purchase iron and motors; they invest in structural reliability, uptime assurance, and compliance frameworks. Our cranes are engineered to operate reliably under variable climatic loads."
Our heavy crane manufacturing capacity is built on advanced machining technology and raw material control. Shandong Dazheng operates a production plant covering 208 acres with 50,000 square meters of modern, climate-controlled workshops. This facility houses large-scale metal cutting, processing, and assembly equipment, ensuring dimensional precision on structural components.
Our critical machining infrastructure includes:
Lifting requirements vary significantly depending on the sector. Dazheng's engineers develop tailormade crane solutions based on project characteristics:
Urban project sites present boundary limitations, height restrictions, and overlapping crane configurations. The GHP Topless (Flat-top) series eliminates the classic cat-head and tie-rod design, reducing the vertical clearance required between overlapping booms. This allows multiple flat-top cranes to be configured at closer vertical intervals, reducing overall construction times.
Industrial complexes, such as wind power, nuclear power, and marine dry-docks, require stable heavy-lift performance. Our high-capacity luffing cranes (like the GHD6090-50, capable of lifting up to 50 tons) handle heavy precast concrete nodes, power generators, and structural steel trusses safely and reliably.
Tall structures require internal climbing systems, high wire rope drum capacities, and stable hoist dynamics at heights exceeding 200 meters. The GHT Topkit series features high wire rope capacity and variable-frequency hoisting machinery to maintain speed and control during tall lifting cycles.
| Crane Class / Category | Representative Model | Maximum Capacity | Boom Length / Tip Load | Primary Structural Standard |
|---|---|---|---|---|
| Topless / Flat-Top | GHP8030-20 | 20 Tons | 80 meters / 3.0 Tons | FEM 1.001 / EN 14439 |
| Topless / Flat-Top | GHP7524-18 | 18 Tons | 75 meters / 2.4 Tons | FEM 1.001 / GB/T 13752 |
| Luffing Jib | GHD6090-50 | 50 Tons | 60 meters / 9.0 Tons | DIN 15018 / EN 13001 |
| Heavy Hammerhead (Topkit) | GHT 7050-20 | 20 Tons | 70 meters / 5.0 Tons | FEM 1.001 / ISO 4301 |
Modern lifting technology is moving beyond traditional mechanics toward digital integration. Our development roadmap, supported by academic collaborations, focuses on structural monitoring, drive control, and safety automation:
Shipping a 20-ton tower crane across continents requires strict logistics and compliance management. Shandong Dazheng handles the entire transport cycle, including containerized shipping of modular mast panels and flat-rack transport for structural slewing tables.
We verify compliance with localized standards, including European CE certification, North American OSHA/ANSI compatibility, and Eurasian EAC certifications. All welding engineers are certified to ISO 9606-1 standards, and our welding processes undergo regular Non-Destructive Testing (NDT) to ensure structural safety.
Empowering global infrastructure through precision manufacturing, academic research, and compliant design standards.
Collaborating with top research universities to optimize structural performance and build custom machinery solutions.
Our lifting platforms and high-capacity cranes are deployed in major construction zones worldwide, including Europe, Southeast Asia, Central Asia, and the Americas.
Technical guidance on selection criteria, mechanical engineering, and compliance standards.
We build our cranes using high-strength low-alloy structural steel, primarily Q355B and Q420. These steels are chosen for their yield strength and low-temperature impact toughness, ensuring structural reliability under high dynamic stress and cold weather conditions. This matches the standard requirements of EN 10025-2.
Flat-top (topless) cranes eliminate the tower head (cat-head) and tie-rods. On multi-crane jobsites, this reduction in height allows cranes to overlap at closer vertical intervals. This simplifies installation, saves vertical clearance, and makes assembly and disassembly safer since the jib can be handled in smaller, modular sections.
Luffing jib cranes are designed for congested cities where space is limited and cranes cannot overhang neighboring properties. By luffing (raising and lowering) the jib, the crane can work within narrow boundaries, avoid overhead obstacles, and park with a short out-of-service radius to prevent interference with nearby structures.
Our engineering collaborations focus on finite element analysis (FEA), wind load calculations, and welding stress analysis. This research helps us refine joint geometry, optimize structural weight without compromising safety, and improve fatigue resistance in dynamic stress areas like connection nodes and slewing bases.
We offer comprehensive technical documentation, detailed foundation planning, and remote or on-site installation guidance. In partnership with local lifting equipment service providers, we help clients with crane commissioning, load testing, operator training, and supply critical spare parts to minimize downtime.
Featuring heavy-duty luffing cranes, hammerhead towers, and electric utility site vehicles for material handling.
