1. Made of Q355D steel with great low-temperature impact toughness, suitable for heavy lifting in cold construction sites.
2. Precisely milled 60° right-handed rope grooves keep wire ropes neatly wound and reduce tangling & breakage risks.
3. All welding seams pass full inspection without missing or cold welds; the welded structure owns high rigidity to resist deformation and cracks.
4. Integrally welded flange and barrel deliver high load capacity for large-tonnage winch working conditions.

Application

• Core rope winding part for main hoisting mechanisms of engineering cranes to lift and pull heavy loads.
• Matching drum for heavy winches in ports, bridge construction and mines, fit for long-term outdoor heavy-duty lifting.
• Winch systems of tower cranes and truck-mounted cranes, orderly storing right-handed wire ropes to guarantee hoisting safety.
• Lifting assemblies of all kinds of large construction machinery, bearing high rope tension and stably transmitting hoisting torque.
