3.Aluminum Alloy  Lebus Groove Split Drum Sleeve High Precision Left-Hand 35° Advantages

Manufactured from lightweight high-strength aluminum alloy, this drum sleeve greatly cuts down the self-weight of the climbing platform to lower the overall load of tower crane lifting mechanisms while retaining excellent structural rigidity, and the material’s natural corrosion resistance effectively resists rust, oxidation and erosion from construction dust, rainwater and acid-base mist on building sites for long-term stable service without frequent surface maintenance; its precisely machined left-hand 35° Lebus rope grooves can guide 4mm cables to arrange neatly without overlapping, squeezing or sharp friction, significantly reducing cable wear and breakage risks to extend the service cycle of traction cables and lower equipment operation costs; the part is finished by integrated whole-piece machining with tight dimensional tolerance following GB/T1804-2000, which ensures high interchangeability and seamless fitting with the matching smooth barrel, and the standardized assembly structure with 2 groups of M8 hexagon socket cap screws enables quick disassembly, replacement and daily overhaul, while the split cutting design reserved per drawing makes internal winding inspection and cable replacement far more convenient.

4.Aluminum Alloy  Lebus Groove Split Drum Sleeve High Precision Left-Hand 35° Application

This specialized Lebus groove aluminum alloy drum sleeve is a core matching component for tower crane climbing platforms, widely deployed on all types of medium and large construction tower cranes used in high-rise residential buildings, ultra-high commercial complex landmarks, municipal stadiums, exhibition centers and prefabricated modular construction projects, and it is also perfectly suitable for small and medium hoisting winch systems supporting infrastructure engineering including cross-river viaducts, urban underground comprehensive pipe galleries and railway station construction, additionally applicable to temporary light-load lifting platforms, short-term engineering hoisting equipment and small lifting machinery for factory workshop material transportation, reliably maintaining stable and smooth cable winding and unwinding performance under frequent reciprocating lifting, long-hour continuous operation and complex outdoor construction working conditions.
