What is a 4-Way Roller Fairlead?

‌Four-way roller fairlead‌ is a fairlead composed of vertical and horizontal rollers, mainly used on ships, and can guide cables from any direction. Its design allows the cable to increase the rolling contact surface when it contacts the roller, thereby reducing the problem of difficulty in relying on the roller for labor-saving operation after changing direction due to sliding contact when the operator pulls it up.

Working principle

The four-way roller fairlead, through its structural design, allows the cable to increase the rolling contact surface when it contacts the roller, thereby reducing the problem of difficulty in relying on the roller for labor-saving operation after changing direction due to sliding contact when the operator pulls it up. This design allows the movement of the cable in various directions to be effectively guided and supported.

Application scenarios

Four-way roller fairleads are widely used on ships, especially on large ships. Due to its simple manufacturing process and material saving, it is suitable for scenarios where the direction of the cable needs to be frequently changed or adjusted, such as ports, docks, etc.

Structural features

Four-way roller fairleads usually include a bearing base plate and a U-shaped support frame. A U-shaped support frame is provided at the top of the supporting substrate at a left-right symmetrical position, and the bottom of the U-shaped support frame is fixedly connected to the top of the supporting substrate by welding. A vertical roller is provided at the side of the U-shaped support frame at a vertical position, and a vertical core shaft is inserted and embedded in the center of the vertical roller, and the upper and lower ends of the vertical core shaft are connected to a vertical shaft seat.
