(1) Orderly multi-layer wire rope spooling
The unique Lebus folded rope groove guides the wire rope to wind neatly, avoiding rope biting, rope squeezing and rope tangling. It evenly distributes the load of each layer, greatly extends the service life of wire rope and improves the safety of lifting operations.
(2) High strength & low temperature resistant material
Q355D steel maintains stable impact toughness at -20℃. It adapts to harsh offshore working conditions such as salt spray, strong wind and low temperature, and resists brittle fracture under heavy dynamic load.
(3) Convenient assembly & maintenance
Bolted split structure. When worn out, only the drum sleeve needs to be replaced instead of the whole drum, which reduces downtime and maintenance cost.
(4) Offshore anti-corrosion protection
Epoxy zinc-rich primer coating provides reliable rust prevention in marine salt spray environment.
Mainly used in offshore engineering: offshore platform cranes, marine deck winches, offshore oil & gas drilling rigs, vessel lifting equipment, floating crane winch systems and other heavy offshore lifting machinery.
It is also applicable for heavy-duty port cranes and mining winches.
