July 3th, the last of MAXTECH's 3t39m electric-hydraulic telescopic Boom Cranes customized for Saudi Arabia's DP World Port completed installation and commissioning, marking the full operation of the first batch of three units. Certified by ABS classification society, the equipment features all-condition load capacities of 35T@6.5M, 10T@15M, and 3T@39M, along with a wide temperature adaptability range of -10°C to 50°C, perfectly meeting the high-temperature environment and multi-cargo operation needs of Red Sea coastal ports.
As a key logistics hub connecting Europe, Asia, and Africa, DP World Port handles over 50 million tons of cargo annually, requiring efficient loading and unloading of diverse goods such as containers and oil equipment. MAXTECH's cranes adopt a box-type hydraulic telescopic boom structure, with a cylinder luffing balance valve design ensuring stable operation within a ±5° tilt angle even at the maximum 39-meter radius. This avoids cargo sway risks of traditional equipment under Red Sea's Beaufort 7 winds (≤20m/s).
The 3T@39M off
Shore Crane lightweight load mode is ideal for ship superstructure maintenance, while the 20T@3M heavy-load capacity meets the needs of lifting large terminal components, forming an "all-range" operational advantage. The crane's cab features an
explosion-proof sealed design (ExdⅡBT4) with integrated air conditioning, fire extinguishers, and torque displays, ensuring operator comfort even in 45°C high temperatures. Combined with wireless remote control and a 360° slewing ring, the equipment achieves 0.5m/min micro-movement precision in narrow spaces like container gaps, effectively improving the efficiency of handling precision equipment.
The delivered marine cranes strictly comply with ABS classification society standards. Main structures use high-strength marine steel plates, with welds inspected by non-destructive testing (NDT). Surfaces are sandblasted to Sa2.5 level and coated with epoxy zinc-rich primer, enhancing corrosion resistance by 40% compared to conventional equipment. For DP World Port's specific needs, MAXTECH optimized three core systems:
- Power System: Dual 75kW motors (IP56 protection/F-class insulation) support 410V industrial power. Equipped with an open hydraulic system's pressure-limiting device, the hoisting speed automatically reduces to 5m/min under heavy loads (≥12T), ensuring stable lifting of valuable goods like oil equipment.
- Safety System: Integrates upper/lower hoisting limits, boom angle sensors, and an emergency hand pump. Braking triggers within 1 second under pressure loss, combined with real-time wind speed monitoring in the cab, minimizing operational risks.
- Environmental Adaptability: Withstands 55m/s strong winds (Beaufort 12) in non-operating status and features ±30° roll resistance design, ensuring stability during Red Sea tidal changes.
MAXTECH's engineering team overcame foundation settlement differences during installation, adjusting outrigger spacing via 3D scanning to reduce the single-unit installation cycle to 7 days. They also provided preventive maintenance training for the port's operation team, enabling real-time monitoring of 12 parameters (e.g., bearing temperature, wire rope tension) through the IoT platform, targeting a 40% reduction in downtime.
The crane's lightweight lifting capability at 39-meter radius is impressive, and its sealed cab and explosion-proof design fully meet our safety requirements for high-temperature and dusty environments. Currently, the three telescopic offshore cranes form a collaborative network: handling 80 tons/hour of fertilizers at bulk terminals, stacking 20-foot containers across zones in the container area with special spreaders, and integrating with the port's AGV fleet to build an intelligent "ship-machine-warehouse logistics chain.
As a benchmark project of the Belt and Road Initiative in the Middle East, this cooperation not only demonstrates China's technological strength in marine lifting equipment but also provides a replicable model for global high-temperature port equipment selection through the "ABS certification + localized customization" approach. As the Red Sea sun shines on the crane booms, Sino-Saudi cooperation in high-end equipment continues to reach new heights.
