Cheap Drum Problem
|
Our Drum Solution
|
|---|---|
|
Smooth surface → rope slips/cross-winds → tangles & breakage
|
→ Precision helical grooves – guides rope layer-by-layer, zero tangling
|
|
Soft steel → grooves wear flat in 1 year → rope damage
|
→ 45# forged steel + surface quenching (HRC 40-45) – lasts 5+ years
|
|
Poor rope fixation → rope end pulls out → dangerous drop
|
→ Double safety clamps – rope end locked securely, zero slippage
