Professional Double Rim Crane Wheel Manufacturer
Double-flange crane wheels, also known as double-rim crane wheels, feature raised flanges on both sides of the tread, effectively preventing the wheel from derailing from the crane track. This dual-flange design provides maximum lateral stability and is the preferred choice for heavy-duty, long-distance crane systems, offering exceptional safety and reliability.
At Glory Rail, our Type SL crane wheels are specifically designed for demanding industrial environments. We manufacture each wheel using forging or casting processes, with materials ranging from medium-carbon steel to high-strength alloy steel (such as the 42CrMo crane wheel grade). Every wheel undergoes precision CNC machining and surface induction hardening to ensure a long service life and minimal wear.
Key Advantage: Compared to single-flange or flangeless wheels, the double-flange design significantly reduces the risk of derailment, making it particularly suitable for applications involving track misalignment, lateral loads, or high-speed operation. This makes it an ideal choice for overhead crane wheels, gantry cranes, port cranes, and steel mill cranes.
