A tie down ratchet and strap includes, a ratchet shaft rotatably mounted in a ratchet body having a slot for receiving a wind-up strap therethough, a pair of ratchet wheels mounted on the ratchet shaft, a ratchet handle with a pawl engaging the ratchet wheels to rotate the ratchet shaft, a locking bar securing the ratchet wheels and ratchet shaft in position when the pawl is disengaged from the ratchet wheels, an anchor strap with a connector for securing the ratchet assembly to a first anchor point, and a wind-up strap including a non-metallic fabric strap with a braided metal outer cover extending continuously over the length of the non-metallic fabric strap.

Fibre rope and hoisting system including such a fibre rope

There is described a hoisting system and method of lifting that make use of a particular fibre rope. The fibre rope includes a plurality of magnets that are embedded within the fibre rope and spaced apart along the rope with a known axial distance between the magnets. The system may include a fibre rope hoisting speed sensor, and a magnetic field sensor that can sense the presence of the magnetic field of the embedded magnets. Using the sensors, the hoisting speed of the rope may be determined by: measuring the time between the passing of consecutive magnets by using the magnetic field sensor; calculating the distance between consecutive magnets using the hoisting speed sensor and the measured time between the passing of the consecutive magnets; and comparing the calculated distance between the magnets with an original, predefined distance between the magnets.

Controlled failure point for a rope or mooring loop and method of use thereof
11597476 · 2023-03-07 ·

A mooring loop is operative to secure a movable device such as a ship in connection with a bollard or other fixed structure. The exemplary mooring loop includes a continuous rope segment that includes at least one coil or a plurality of coils. The rope segment defining the mooring loop includes an inner core surrounded by an outer jacket. A plurality of controlled failure points are included in the rope segment. The failure points enable the rope segment to permanently elongate in response to an applied tension force at a level above a working range, which elongation is visibly observable. The controlled failure point is defined between segmented ends of a severed inner core such that only the outer jacket is located at the controlled failure point.
