99m Capacity Luffing Drum for Φ12 Wire Rope, High‑Strength Welded Drum

1.Description

This 99‑meter rope‑capacity luffing drum serves as a core component for crane luffing mechanisms, designed for Φ12 mm steel wire rope. Fabricated by high‑strength steel plate integral welding with precision‑machined rope grooves, it ensures neat wire‑rope winding and effectively prevents rope jumping and disordered winding. Strictly manufactured per drawing dimensions with accurate flange and mounting interfaces for excellent assembly compatibility. Featuring high structural rigidity to resist deformation under alternating loads, it reduces wire‑rope abrasion and extends service life for both drum and rope. Ready for direct matching with various crane luffing winches; custom modification is available

3.Advantage

Equipped with sufficient 99‑meter rope storage space, this luffing drum satisfies long‑stroke rope winding and unwinding requirements of luffing mechanisms. Precisely processed grooves enable smooth rope arrangement to relieve squeeze wear and prolong wire‑rope service life. Welded by high‑strength steel plates, the drum obtains outstanding rigidity against impact and deformation under alternating heavy loads. Drawing‑oriented machining guarantees precise dimensions of mounting holes and flanges for convenient assembly and favorable interchangeability. Side protective flanges restrict rope displacement to avoid rope dislodgement and improve operational safety and reliability.

4.Application

It is mainly used in crane luffing winch systems for luffing mechanisms of truck‑mounted cranes, mobile cranes, crawler cranes, tower cranes and other construction machinery. It also works for engineering hoists and traction winches to realize long‑distance wire‑rope winding and unwinding. Widely deployed in building construction, field hoisting and engineering equipment supporting projects, it supports non‑standard manufacturing per client drawings.
