Professional Double Rim Crane Wheel Manufacturer
Single-flange crane wheel, also known as a single-rim crane wheel, features a raised flange on only one side of the tread. This single-rim/flange design allows the wheel to be guided along one side of the rail while permitting limited lateral movement on the other side. It is particularly suitable for monorail systems, trolley applications, and crane runways with lighter loads, where precise single-side guidance is required.
At Glory Rail, our DL-type single-flange crane wheels are specifically designed for monorail crane systems and trolley wheel applications. Each wheel is manufactured from forged alloy steel (such as 42CrMo) or medium-carbon steel, and undergoes precision CNC machining and induction surface hardening. As an experienced supplier of single-flange crane wheels, we ensure that every wheel delivers a long service life, low wear, and reliable performance in demanding industrial environments.
