Crane Wheel Blocks Empower Efficient Container Handling at Indonesia

In the container loading and unloading operation upgrade project of Belawan International Container Terminal (BICT) in Indonesia, 5 high-performance wheel block systems supplied by Mailun serve as the core components ensuring the efficient operation of the terminal’s heavy-load and high-frequency operations, providing solid support for enhancing local port logistics capabilities.

Belawan Port is located in Medan City at the western end of the Strait of Malacca, along the global main shipping route and adjacent to Singapore Port, an international shipping hub. It is a crucial foreign trade logistics node in Indonesia. With the continuous growth of the port’s container throughput, the existing loading and unloading equipment can no longer meet the expansion needs. The delivered cranes are configured with dedicated wheel block systems, forming a stable multi-wheel drive and load-bearing structure. They can achieve a container stacking height of 6+1 layers and a stacking width of 6 columns, with a single crane lifting capacity of 40 tons, fully adapting to the heavy-load handling needs of large containers at the terminal. As the core transmission component connecting the crane to the ground, the design and performance of the wheel block system directly determine the equipment’s operational stability, tire wear rate, and work efficiency. The wheel block system customized by Mailun for this batch of RTG cranes adopt a unique wheel rotation during steering technology: when the crane needs to switch stacking lanes or adjust the operation direction, the wheel block system can drive the wheels to rotate synchronously during steering, avoiding severe friction between tires and the ground during the "hard steering" of traditional cranes. This design not only reduces the wear rate of rubber tires by more than 30% and extends tire service life but also minimizes rolling damage to the terminal yard surface, lowering the terminal’s ground maintenance costs.

Data shows that the terminal’s daily container handling capacity has increased from the original 800-1000 TEUs to 1200-1400 TEUs, and the yard space utilization rate has increased by 25%, effectively alleviating the congestion pressure of cargo transit on the Strait of Malacca route and providing key equipment support for the efficient operation of Indonesia’s foreign trade logistics. As the "walking core" of the crane, the wheel block system’s characteristics of low wear, high stability, and adaptability to heavy loads and complex working conditions have become one of the important reasons for Mailun’s equipment to continue gaining recognition in the Indonesian port market.
