A tension measuring assembly includes a pair of straps that has an attachment that can be attached to a tie down chain which is securing cargo on a flatbed trailer. A tension meter is provided and each of the pair of straps is attached to the tension meter. The tension meter measures tension in each of the straps to measure the tension in the tie down chain when the straps are attached to the tie down chain. A display unit is in remote communication with the tension meter and the display unit displays the tension measured by the tension meter. In this way the display unit facilitates a driver of the vehicle to monitor the tension of the tie down chain.

A strap detection system for detecting if strap such as a load securing strap is torn or in need of replacement. The system includes an electric device on the strap in communication with a detection module.

A tension monitoring device that attaches or clamps onto to a tensioned cargo load securing strap and wirelessly communicates the tension level to the driver via a remote device, such as a mobile smartphone. One or more devices may be installed on a vehicle or trailer to be simultaneously monitoring the tension conditions during transit. The tension signal from the device is received and processed by the mobile smartphone application to display the real-time tension relative to unsafe levels and transmit alerts to the driver when an unsafe or undesired condition occurs. The tension monitoring device includes an electromechanical sensor and microprocessor, powered by a battery, and packaged inside two hinged weatherproof housings for the ability to clamp onto a tensioned cargo strap.

A strap system comprising a first strap extending between a first end and a second end. The first end is connected to a first attachment mechanism. The strap system further comprises a second strap extending between a third end and a fourth end. The fourth end is connected to a second attachment mechanism. The strap system comprises a load transmission device connected to the second end of the first strap and to the third end of the second strap. The load transmission device is arranged to transmit a signal in response to a tension force in the first and second straps falling below a threshold force.

A line tensioning device for adjusting and maintaining consistent tension in an anchored line has a ratchet assembly and a tension indicator assembly. The tension indicator assembly secures the device to an anchoring point and permits linear movement of the ratchet assembly between the line and the anchoring point. The tension indicator assembly includes a compressed spring and a plunger with a tension indicator mark visible externally from a plunger housing above a predetermined tension force threshold.

An anchor device for a cargo securement strap includes a frame configured to engage a mounting track. The anchor device further includes a hook receiver coupled to the frame. The hook receiver is configured to receive a hook of the cargo securement strap. The anchor device further includes a keeper coupled to the frame. The keeper includes a keeper body and at least one keeper finger extending from a side of the keeper body. The keeper is configured to move between a first position and a second position. In the first position, the at least one keeper finger contacts a bolt and the keeper body is positioned to retain the hook. In the second position, the keeper body is positioned to allow for removal of the hook from the hook receiver.

A line tensioning device for adjusting and maintaining consistent tension in an anchored line has a ratchet assembly and a tension indicator assembly. The tension indicator assembly secures the device to an anchoring point and permits linear movement of the ratchet assembly between the line and the anchoring point. The tension indicator assembly includes a compressed spring and a plunger with a tension indicator mark visible externally from a plunger housing above a predetermined tension force threshold.

A strap detection system for detecting if strap such as a load securing strap is torn or in need of replacement. The system includes an electric device on the strap in communication with a detection module.

A system includes several load cells, each coupled to a lashing that secures shipping containers, accelerometer cells, each coupled to a shipping container at the top of a stack, and an inclinometer cell coupled to a cargo ship. The cells are configured to transmit data to a computer. All the cells comprise a processor programmed to acquire a time series of measurements and, preferably, decompose the time series into a sum of sinusoidal signals, each having a frequency and an amplitude. Alternatively, the computer can be programmed to decompose the time series. The computer is programmed to identify the signal components caused by the roll of the cargo ship or by resonances in shipping container stacks. The computer estimates cumulated damages caused by fatigue in the lashings and/or twist locks. The system is used to trigger alarms and/or schedule maintenance.

A computer system handles tension of at least one strap arranged for strapping cargo in a vehicle. The computer system includes processing circuitry configured to obtain cargo information; obtain vehicle information; determine, based on the cargo information and the vehicle information, a pack plan, wherein the pack plan comprises a planned tension; determine to start loading the cargo in the vehicle and using the planned tension; obtain information about a first current tension of the at least one strap when the loading is finished and before the vehicle drives; compare the planned tension and the first current tension; and to determine to initiate a first action when a result of the comparison indicates that the first current tension is different than the planned tension.
