PERFORMANCE
The crane wire rope drum is the core component of the lifting mechanism, which is mainly used for orderly winding and power transmission of wire rope to realize the lifting and lowering of heavy objects. As a key component of the load-bearing system, its performance directly affects the load capacity, running stability and safety of the crane. According to different application scenarios, it can be divided into two types: single-layer winding and multi-layer winding, which are widely used in various types of bridge, gantry, tower and port cranes.
As an important hub connecting the drive system and the hoisting equipment, the performance of the crane wire rope drum directly determines the load capacity, running stability and operation safety of the crane. According to the structural characteristics, it can be divided into three types: single-layer winding, multi-layer winding and friction.
In harsh working conditions such as metallurgy and ocean, it is necessary to use drums with special materials and protective designs, and shorten the maintenance cycle to 50% of conventional equipment. Crane wire rope drums have a wide range of applications, covering almost all industrial, construction, and logistics fields that require vertical lifting, horizontal traction, or luffing. The reliability of the crane wire rope drum design and manufacturing is directly related to the safe operation of the entire lifting equipment.
PURPOSE
Manufacturing and Heavy Industry: Used in machining, assembly workshops, and steel mills (casting cranes, clamp cranes), they handle raw materials, semi-finished products, and heavy equipment. Logistics and Ports: Used in port terminals for container gantry cranes, yard cranes, and portal cranes, they are key links in the global logistics chain. Construction: Tower cranes, construction elevator winches, and other equipment are indispensable equipment for modern construction. Power and Energy: Used in hydropower, thermal, and nuclear power plants for the installation and maintenance of large equipment such as generators and turbines (typically using high-safety cranes). Mining and Metallurgy: In mine hoists, drums (often called winches or friction sheaves) are responsible for lifting cages or personnel from shafts hundreds or even thousands of meters deep, representing one of the most demanding safety applications. Shipping and Offshore: Used in shipyard gantry cranes and ship deck cranes for shipbuilding, repair, and cargo loading and unloading. Water conservancy and municipal engineering: Hoists used for sluice gates and dams, which raise or lower the gates by retracting and releasing the wire rope on the drum.
