Description
High-Strength Construction · Precision Machining · Stable Rope Winding · Reliable Transmission Core
Crane drum components are the core transmission parts of the hoisting mechanism, responsible for winding steel wire rope and converting motor torque into stable lifting motion. Manufactured from high-strength carbon steel or alloy steel, our crane drums feature precision-machined rope grooves, excellent concentricity, and superior wear resistance.
They are widely used in overhead cranes, gantry cranes, electric hoists, winch systems, and other lifting equipment, ensuring smooth rope arrangement, reduced wear, and extended service life.
Advantages
Made of Q345B, 45# steel, or alloy steel with heat treatment process for improved strength, fatigue resistance, and durability.
CNC-processed spiral grooves ensure uniform wire rope winding, minimizing rope extrusion and extending service life.
Accurate dynamic balancing and strict concentricity control reduce vibration and ensure smooth lifting performance.
Optional surface hardening or coating treatment enhances corrosion resistance and extends operational lifespan.
Compatible with various shaft types, couplings, bearings, and gearbox configurations.
Application
- Overhead Crane Hoisting MechanismUsed in single girder and double girder cranes for stable load lifting and lowering.
- Gantry Crane SystemsEnsures safe and efficient rope winding in outdoor and heavy-duty applications.
- Electric Hoists & WinchesCore drum unit for rope storage and torque transmission.
- Port & Industrial Lifting EquipmentSuitable for metallurgy, shipbuilding, construction, logistics, and heavy manufacturing industries.
