Products Description
High Tensile Tower Crane Cable adopts premium high carbon steel wirethrough cold drawing and precise heat treatment. Two core structural categories are produced to match different tower crane functional parts:
- Non-rotating multi-layer strand cable (18×7, 35W×K7): Inner & outer strands twisted in opposite directions, effectively eliminate load spinning, ideal for main lifting hoist of high-rise tower cranes.
- Line contact flexible cable (6×36WS, 8×25Fi): Warrington-Seale composite structure, uniform stress distribution, outstanding bending fatigue resistance, used for trolley travel and jib luffing systems.
Two core types (FC fiber core / IWRC steel core) and three surface treatments (bright oiled, hot galvanized, PVC coated) are optional to adapt inland construction, coastal salt spray and outdoor long-term exposure environments. Compact strand technology is available for upgraded wear resistance and longer service life.
Key Features
Ultra High Tensile & Stable Breaking Load
Three strength grades 1770MPa / 1960MPa / 2160MPa optional; IWRC steel core version boosts breaking force by 15%–25% vs fiber core, bear heavy dynamic load of tower crane high-speed lifting.
Anti-Rotating Design For High-Rise Lifting
18×7 & 35W×K7 anti-twist structures adopt reverse lay strands, avoid hook rotation, cable kinking and strand disorder during long vertical lifting, greatly reduce safety risks on construction sites.
Excellent Bending Fatigue Resistance
6×36WS line-contact structure reduces internal wire friction loss, withstand thousands of reciprocating winding on small-diameter crane drums, extend service cycle and lower replacement frequency.
Three Optional Surface Anti-Corrosion Treatments
- Bright Oiled Finish: Standard indoor construction, pre-lubricated inside strands for self-maintenance.
- Hot-Dip Galvanized: Uniform zinc coating on every single wire, resist rust in humid, coastal and rainy construction sites.
- PVC Nylon Coating: Outer protective jacket for anti-scratch, insulation and decorative demands.
Dual Core Selection To Match Working Conditions
- FC Fiber Core: Rich internal lubricant storage, superior shock absorption, fit medium-load trolley & luffing cables.
- IWRC Independent Steel Core: Anti-crushing, high temperature resistant, perfect for multi-layer winding main hoist heavy-load cables.
Compact Strand Upgrade Option
Compacted wire rope smooth outer surface, larger contact area with pulley sheaves, lower surface abrasion, service life increased by over 30% compared with ordinary round strand cable.
