Overview

Just like crane wheels are easy to wear as the most vulnerable components in the traveling mechanism, drum assemblies 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 drum assemblies: seamless pipe rope drums and Q355 or S355 steel plate drum shells. We utilize seamless steel tubes for smaller-diameter drums. Generally, rolling steel plates are used to manufacture crane drums with larger diameters. Cast iron drums feature a self-lubricating property, resulting in better compatibility with wire ropes. By changing the material of the drum shell, flange, stud, axis, and rope clamp, etc., it can adapt to low low-temperature working environment down to -40℃.

Custom-designed wire 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 Purui steel plate rope drum can accommodate diameters of up to 3000mm, and the groove hardness and hardness depth can be customized as per actual application from 180 HB to 45 HRC. UT, MT, VT NDT reports on overall welding joints and weld seams will be provided for better safety assurance.

Drum assemblies that Purui manufactured feature compact structures, lightweight, and high-assembly precision. They are also frequently used parts of metallurgy, mining, port, and the energy industry.
