Grooved Crane Wire Rope Drum

High Strength and Durability

Each grooved drum is made from forged alloy steel or welded steel plates. This build gives the drum strong load-bearing capacity for heavy-duty lifting.

Accurate Groove Design

CNC-machined grooves match your rope diameter and lay length. Proper groove geometry keeps each rope turn aligned. It reduces wear and prevents slippage and bird-caging.

Extended Service Life

Heat treatment and anti-corrosion coatings add surface hardness and stability. The result is long-term performance for the crane rope drum, even in harsh environments.

Hanko grooved crane wire rope drums combine strength, precision, and safety. They ensure smooth lifting and reliable operation for heavy-duty crane applications.

Product Details

Each grooved crane wire rope drum is manufactured from 42CrMo, 65Mn, or ZG430-640 alloy steel. The CNC-machined grooves match your specified rope diameter and lay length. They provide smooth winding and prevent rope jumping.

Heat treatment increases surface hardness to HRC40–48, while the core maintains toughness for impact resistance.

The hoist drum crane is fitted with welded bearing seats for stability. Anti-rust coatings and thermal spray finishes protect against corrosion in harsh environments.

Single, double, or multi-groove crane rope drum designs are available, with customizable diameter, length, and mounting styles. All products are tested under crane wire rope standards with load and non-destructive inspections before delivery.
