Single Drum Luffing Drum Q355C Steel For Crane Luffing Mechanism

Product Description

This luffing drum is integrally machined from Q355C low-alloy steel, featuring stable impact toughness at 0℃ for outdoor crane luffing mechanisms. The barrel is equipped with precisely machined integrated rope grooves to arrange cables evenly and reduce wear. The integrated flange structure delivers high rigidity and smooth operation, widely matched with luffing winch systems of cranes and construction machinery.

Technical Parameters

Application

This Q355C luffing drum is mainly applied to the luffing winch system of various engineering cranes. It retracts and releases luffing steel wire ropes to lift and lower the crane boom, adjusting the working range and operating radius. It is compatible with truck cranes, crawler cranes, truck-mounted cranes and other mainstream lifting machinery. It fits outdoor lifting operations in ports, factories and construction sites under normal temperature conditions. It stably bears alternating loads of the luffing mechanism to ensure smooth and controllable boom movement. It can also match the amplitude adjustment assembly of small and medium-sized engineering winches. Benefiting from the excellent low-temperature toughness of Q355C, it operates reliably in temperate outdoor construction in winter. It is an indispensable core load-bearing reel for cranes to realize luffing functions.

Matters Need to Attention

• Suitable for environments above 0℃; avoid long-term use in cold weather to prevent cracking.
• Tighten flange bolts evenly diagonally to stop eccentric shaking and groove wear.
• Never overload, overload leads to groove deformation and fatigue cracks.
• Check grooves regularly, replace the drum once cracks or dents appear.
• Repaint regularly for outdoor application to resist rust.
• Wind steel wire neatly, chaotic winding will damage the barrel.
• Avoid impact during transportation and maintenance to prevent hidden cracks.
