Diesel Generator Power Pack for ZPMC RTG Cranes
ZPMC partners with Haifeng Power to deliver modular, high-performance generator systems tailored for integration with complex port equipment.
Project Background
ZPMC (Shanghai Zhenhua Heavy Industries Co., Ltd.) is a global leader in port machinery manufacturing, renowned for its Rubber-Tired Gantry (RTG) cranes and Quay Cranes (QCs) deployed in major ports across Dubai, Marseille, Rotterdam, Singapore, Los Angeles, and more.
In many non-electrified container yards, RTG cranes cannot rely on shore power due to infrastructure limitations. To ensure uninterrupted operation, ZPMC integrates custom diesel generator power packs onto the RTG structure. These units provide continuous and reliable power to the crane’s hoisting system, control electronics, lighting, and communication modules—supporting the crane’s full range of mobile operations.
Project Challenges
Limited Installation Space & Weight Constraints
RTG cranes have highly limited mounting areas and must maintain structural balance and hoisting safety. Generator weight and volume must be tightly controlled.
High-Load, Long-Hour Duty Cycles
RTGs operate 10–16 hours per day under high load with frequent starts and stop cycles, requiring exceptional system durability, heat dissipation, and fatigue resistance.
Extreme Environmental Variations
ZPMC cranes operate across climates—from Middle Eastern heat and African dust to Southeast Asian humidity and coastal salt air—demanding a globally adaptive generator system.
Complex Integration & Commissioning Coordination
As a subsystem of a highly sophisticated machine, the generator must interface seamlessly with ZPMC’s control system and pass factory pre-commissioning tests before delivery.

Testimonials
"Our partnership with Haifeng Power has been critical in modernizing our terminal operations. The integrated diesel power solution installed on our RTG cranes delivers strong, steady output even under heavy lifting cycles. We particularly value the compact design and remote monitoring functions, which make daily operations smoother and maintenance planning much easier. This solution has directly improved our port efficiency and reduced downtime significantly."
Shuanglin Zhang
Project Manager
"The ZPMC RTG diesel generator power pack has exceeded our expectations in reliability and performance. Operating in one of the hottest and dustiest port environments in the Gulf, the units start instantly, provide stable power to our RTG cranes, and require minimal maintenance. The custom anti-corrosion coating and optimized cooling system have made a real difference, allowing us to keep our container yard running around the clock without interruption."
