3.Advantages
(1) Featuring the unique Double‑Folded Lebus groove structure, the drum guides orderly rope crossover during multi‑layer winding. It effectively avoids rope tangling, biting and crushing, and prevents the deformation commonly seen on plain drums. Stable performance is maintained even for winding of more than 10 layers.
(2) Friction and extrusion between adjacent rope loops are minimized to greatly reduce wire‑rope wear. Compared with conventional plain or single‑helical grooved drums, wire‑rope service life can be extended by 2‑5 times, which directly cuts rope‑replacement costs.
(3) Load stress is evenly distributed across rope layers. Local stress concentration and impact loads are reduced during heavy‑load pulling and cable retraction, lowering rope‑breakage risks and improving operational safety.
(4) The Lebus‑groove design achieves large rope‑storage capacity within limited drum length, saving valuable installation space for marine, mining and traction‑type equipment.
(5) Rope‑arrangement‑related failures are greatly reduced, cutting unplanned downtime caused by maintenance and rope replacement, and improving overall equipment efficiency and operational continuity.
(6) Groove parameters, matching rope diameters and groove hand can be fully customized according to project requirements. It can also serve as a retrofit replacement drum for existing winch systems without replacing the complete winch unit.
(7) Reliable welding quality, thorough deburring treatment and anti‑corrosion surface coating guarantee long‑term stable operation under offshore, open‑air and high‑humidity working conditions.
4.Application
This Double‑Folded Lebus grooved winch drum is ideally suited for high‑capacity multi‑layer cable spooling and heavy‑duty pulling scenarios where stable rope arrangement and long‑term reliability are critical. As a core component for marine winches, offshore cable reels and harbor equipment, it meets stringent requirements for corrosion resistance and structural integrity. In industrial sectors, it fits mining traction winches, forestry logging winches and large‑scale cable‑reeling systems, delivering consistent performance under heavy‑load and long‑stroke cable‑retraction conditions. Thanks to its Double‑Folded Lebus groove geometry, it is an ideal option for winch systems requiring neat multi‑layer rope winding, regular rope maintenance or drum retrofitting. For OEMs and maintenance teams in pursuit of dependable, high‑strength drums compliant with professional engineering standards, this component provides a robust solution for demanding offshore, open‑air and high‑humidity operating environments.
