20 Ton SWL Heavy‑Load Marine Cable Guide Sheave 1500 mm

1.20 Ton SWL Heavy‑Load Marine Cable Guide Sheave 1500 mm Description

Our heavy‑load marine cable guide sheave is precision machined for offshore and marine winch applications. Designed for Ø139.8±0.5 mm umbilical cable, this 1500 mm sheave delivers 20‑ton safe working load with DAF 3 dynamic factor. It permits ±0.5‑degree sideways cable deflection and sustains full‑force impact loads over extended operating hours, protecting expensive umbilical cables against crushing, friction and sheath damage.

This heavy‑load marine cable guide sheave is a fully machined critical component widely deployed within offshore marine engineering and heavy‑duty winch systems. Specially engineered for large‑diameter umbilical cable routing, it serves as a guiding wheel to control cable movement during deployment, recovery and tensioning operations. Built to endure harsh offshore environmental conditions and cyclic dynamic loads, the sheave minimizes extrusion wear, local stress concentration and outer‑jacket abrasion on high‑value subsea umbilical cables. It can sustain 100 % of rated working force continuously for several hours under impact‑loading scenarios, offering reliable performance for long‑time non‑stop field operations.

3.20 Ton SWL Heavy‑Load Marine Cable Guide Sheave 1500 mm Advantage

1. Optimized cable groove with adapted slot radius. The special groove contour fits the outer profile of umbilical cables perfectly. It effectively disperses surface contact pressure and reduces squeezing friction, greatly lowering risks of cable sheath cracking and abrasion. A ±0.5‑degree sideways deflection tolerance accommodates minor installation misalignment that commonly occurs on‑site.
2. Reserved bearing installation seat. The sheave hub is pre‑machined for bearing assembly. Bearings need to be fitted during customer’s on‑site assembly and are not included within the delivery scope.
3. Two dedicated handling holes with rounded edges. Approximately Ø80 mm lifting holes are machined on the disc surface. Round chamfered edges eliminate sharp corners, making hoisting, transport and on‑site installation safer and more convenient.
4. Integral one‑piece steel machining structure. No welded splicing joints. Excellent structural rigidity and deformation resistance, stable performance under frequent dynamic tension and heavy offshore impact loads.
