Frequently Asked Questions

Q: What is the difference between Lebus and spiral grooves?

Lebus grooves are specifically designed for high-load applications to ensure the rope is wound in a precise, non-overlapping manner, whereas spiral grooves provide general smooth winding for various load levels.

Q: Can the grooved drum be customized for specific rope diameters?

Yes, our CNC center allows us to customize rope grooves for diameters ranging from 3mm to 190mm based on your specific operational requirements.

Q: What materials are used for the construction of the drum?

We use high-grade alloy steel, which is then precision machined to ensure the drum can withstand extreme pressure and environmental corrosion.

Q: In which environments can these winch drums operate?

Our drums are designed for extreme temperatures ranging from -40℃ to +45℃, making them suitable for arctic, tropical, and deep-sea offshore platforms.

Q: Does LBS provide certifications for marine use?

Yes, our products are ISO9001 certified and meet CCS (China Classification Society) standards for marine and offshore applications.

Q: What is the typical rope capacity for these drums?

Depending on the custom specifications, our grooved drums can accommodate rope capacities from 10 meters up to 10,000 meters.
