Lebus Double Fold Groove Drum For 42mm Steel Wire Rope 7 Layers Winding

Lebus Double Fold Groove Drum For 42mm Steel Wire Rope 7 Layers Winding

Product Description

This drum assembly made of Q355D steel adopts LBS Lebus double-fold rope groove with 55° left-hand helix for 7-layer wire rope winding. The rope groove edges are rounded to ensure smooth running of 42mm wire rope and reduce wear. Its welds comply with JB/T11157-2011 standard for high structural strength. Anti-rust paint is coated on specified surfaces. It is built for heavy-duty lifting applications and custom manufacturing is available.

Technical Parameter

Advantages

• Constructed from Q355D low temperature impact steel, it delivers excellent toughness for heavy-duty operations in field, offshore and other harsh environments.
• LBS Lebus double-fold rope groove supports stable 7-layer winding, evently distributing wire rope stress and greatly extending rope service life.
• Rounded groove edges enable smooth rope travel, reducing squeezing, jamming and abrasion to improve operational safety.
• Welding follows JB/T11157-2011 standard with graded weld inspection, ensuring stable structure and outstanding fatigue resistance.
• Targeted anti-rust coating with protection for key fitting surfaces balances corrosion resistance and assembly accuracy, custom non-standard sizes available.

Matters Need to Attention

• Inspect rope grooves, welds and mounting holes of the drum assembly before installation. Remove burrs and debris, align thread holes to ensure smooth bolt assembly.
• Use 42mm diameter wire rope for operation. Do not overload or apply shock loads to avoid damage to drum and wire rope.
• Monitor wire rope arrangement during lifting work to prevent rope jumping and squeezing. Regularly check groove wear and weld cracks.
• Store in dry and ventilated area to avoid moisture corrosion. Protect brake disc surface and precision mounting surfaces during maintenance to preserve accuracy.
• Reapply anti-rust paint promptly if coating on non-working surfaces is damaged, to prevent steel corrosion and extend service life.
