Just like crane wheels are easy to wear as the most vulnerable components in the traveling mechanism, Crane drums from the hoisting mechanism are the same due to the long-term use of their grooves. Furthermore, when a drum becomes worn, it accelerates the wear of the wire rope, which can lead to significant safety hazards. On the other hand, replacing drums is a more intricate process compared to replacing crane wheels. It triggers the disassembly of the entire hoisting unit, including the hoisting motor, brake system, and wire rope, in conjunction with the hook (or any other attached hanger, which may complicate the procedure). To make a long story short, the quality of wire rope drums holds paramount importance in a crane.
Purui specializes in manufacturing two types of drums: cast iron rope drums and steel plate rope drums. we utilize seamless steel tubes for smaller-diameter drums. Generally, cast iron drums feature a self-lubricating property resulting in better compatibility with wire ropes. Rolling steel plate manufactures crane drums with larger diameters.
Custom-designed rope drums are commonly required with unique specifications to meet various projects. Our manufacturing capabilities enable us to meet specific needs in the market. The Weihua steel plate rope drum can accommodate diameters of up to 3000mm and surface hardness of 60 HR.
