CBT38-1999 Three-Roller Chock | Xifan Marine

Reliable mooring equipment plays an important role in vessel safety and efficient rope handling. During mooring operations, ropes are exposed to tension, friction, vessel movement, wind, waves, and changing environmental conditions. Suitable rope-guiding equipment helps maintain the intended rope path and supports reliable mooring operations.

The CBT38-1999 Three-Roller Chock is a marine deck fitting designed to guide mooring ropes through designated positions on ships and other marine structures. Its three-roller configuration allows the rope to be guided in different directions according to the equipment arrangement, helping manage rope movement and reduce sliding friction at the roller contact points.

Xifan Marine CBT38-1999 Three-Roller Chocks are intended for shipbuilding, vessel maintenance, marine equipment supply, and offshore-related projects. With practical construction and manufacturing options based on customer drawings and technical specifications, Xifan Marine supports different vessel layouts and mooring equipment requirements.

CBT38-1999 Three-Roller Chock

A three-roller chock is a marine rope-guiding fitting equipped with three rollers to accommodate the intended mooring line route. Depending on its design, the rollers help guide the rope while allowing rolling contact at the points where the rope changes direction.

The CBT38-1999 designation should be checked against the applicable product standard or customer drawing to confirm the exact configuration, dimensions, and technical requirements before ordering.

How Does a CBT38-1999 Three-Roller Chock Work?

A three-roller chock is installed at a suitable position on the vessel's deck, bulwark, or other designated supporting structure, according to the approved mooring arrangement.

During mooring operations, the rope passes through the chock and contacts the rollers as it follows the required lead. The rollers allow rotational movement at the contact points, helping reduce sliding friction compared with an equivalent fixed contact surface under suitable operating conditions.

The chock helps guide the rope and maintain the intended mooring line direction. Its performance depends on the roller design, rope compatibility, installation position, structural support, and operating conditions.

When selecting a CBT38-1999 three-roller chock, customers should consider the required dimensions, rope diameter, rope lead angles, mounting arrangement, design loads, material, surface treatment, and applicable project or classification requirements.
