21.00-35RTG Drive Rim ZPMC Port Machinery spare parts

The ZPMC 21.00-35RTG idler wheel flange is specially designed for ZPMC 21.00-35 specification RTG tire-mounted container gantry cranes. It is a core load-bearing component of the traveling system. It is precision forged from ZG50MnMo high-strength alloy cast steel, with a robust structure, wear resistance and impact resistance. It is manufactured to original factory standards, is compatible with the idler mechanism, connects the wheel axle and tire, bears the load of the whole machine and cooperates with the traveling positioning, prevents derailment and deformation, and ensures smooth and stable operation of the crane. It is suitable for heavy-duty, dusty, humid and salt spray operation scenarios such as ports and docks.
As a key component of the RTG crane’s traveling system, this product is the preferred choice for industry professionals due to its superior materials and precision manufacturing. Its core functions include heavy load bearing, positioning, and shock absorption during operation. It boasts high strength and stability, is resistant to salt spray and abrasion, reducing traveling system failures and maintenance costs. Compatible with the entire ZPMC 21.00-35RTG series, it supports continuous heavy-duty operations in ports 24 hours a day. This product adheres to ZPMC original factory standards and complies with ISO/TS 16949 and ISO 20975 standards, maintaining the same quality as the original manufacturer. It can be directly replaced and is easy to install. Key technical parameters are precisely matched: tensile strength ≥680MPa, rated load 120t, flange width 180mm±2mm, operating temperature -20℃~60℃, protection rating IP54. Precise dimensions, secure positioning, and assembly without loosening or jamming ensure a balance between load-bearing capacity and stability, making it suitable for complex port environments and facilitating efficient crane operation.
