RISU LANE MARKER

RISU LANE MARKER is not simply a single rope. It is made up of a series of connected floats designed to absorb waves as effectively as possible.

Each float is engineered to take in waves and limit their release, helping reduce wave movement in the lane. We also carefully designed the buoyancy and positioning of the floats so that the entire lane marker works together like a large chamber that captures and absorbs waves.

By considering both the performance of each float and the overall structure of the lane marker, RISU Kogyo has created a product that helps provide a calmer, more competitive swimming environment.

The box-shaped configuration allows the floats to rotate as they intercept incoming waves. This converts wave energy into rotational movement, helping absorb and reduce the waves.

By working together to form a large wave-capturing enclosure, the floats deliver a high level of wave-absorption performance.

To achieve the right balance of buoyancy and stability, we use foam materials and have increased the width and size of the floats and wings.

At RISU Plastic Group, we are committed to developing environmentally conscious products. The RL-150T model is made with approximately 30% plant-based plastic.

Maintaining lane ropes can be time-consuming, especially when gaps develop between the floats. The RL-150T makes maintenance easier with its unique two-piece repair float.

Designed to fill gaps quickly and securely, the repair float helps maintain the lane marker’s high wave-absorption performance.

Lane ropes can pose an injury risk when swimmers come into contact with them, particularly for visually impaired para swimmers and older users. The RL-150Y was developed with the goal of helping prevent injuries caused by lane markers.

• Its flexible materials and elastic float design provide a softer surface than conventional low-foam floats, helping improve swimmer safety.
• The design also helps prevent fingers from becoming trapped. Gaps are smaller than 8 mm, so a 3-year-old child’s little finger cannot pass through them. In addition, R-shaped wings help absorb impact when a swimmer’s hand or body comes into contact with the lane marker.
• Because the wings are connected only at the base, they can flex when touched and help absorb impact safely.

The RL-150Y features a high wave-absorption float design based on the technology developed for the RL-150T.

Its connected floats work together to form a large wave-capturing enclosure, allowing the lane marker to absorb more waves and help create a calmer swimming environment.

Lane rope floats are exposed to UV radiation, impact, and changing temperatures, which can cause conventional plastic materials to deteriorate over time. The RL-150Y uses carefully selected materials to improve long-term durability.

Its EVA and PE resin floats offer excellent elasticity and flexibility. They are less likely to harden in low temperatures, helping them remain flexible even in cold environments and reducing the risk of scratches or damage.

EVA resin also provides strong resistance to ozone, UV exposure, and stress cracking, helping the RL-150Y maintain reliable performance over time.
