Common failures of wooden cable drums during sea transportation-Dampness and mold

Wiki Article

Shipping wooden cable drums overseas is trickier than most buyers think. From our factory experience, the most frequent issues include flange cracking, loose bolts, and drum deformation.

High humidity and wood expansion during long voyages often cause flanges to split, while vibrations can loosen bolts, reducing drum stability. Heavy cables may deform the drum if the barrel isn't reinforced, making unwinding difficult on-site.

Mold and moisture damage is common in improperly dried wood, leading to weaker structure and buyer complaints.

Edge damage from container lashing and bottom damage during unloading are also typical, especially when protective measures are ignored.

To prevent failures, we recommend proper flange thickness, torque-controlled bolts, kiln-dried wood, and secure container handling. These precautions ensure drums arrive intact, safe, and ready for immediate use.

During the initial shipment process, due to a lack of experience, we encountered mold growth.

This was due to the wood's moisture content exceeding 20%. Therefore, over the next decade or so, we mastered methods to reduce moisture content, ensuring that no exported products developed mold.

The humid environment of sea transport further promotes mold growth. If the wood is dry from the start, and the container doesn't get wet, mold growth won't occur.
