Most of the lashing rods are made of metal, which can effectively fix the goods through specific structural design; The lashing belt is usually made of high-strength fiber, with excellent flexibility and tensile property, which can tightly bind goods; The twistlock uses a unique rotary locking mechanism to closely connect the container and the means of transport. They are widely used in transportation scenarios such as ships and trucks, which can counteract the external forces generated by vibration and turbulence during transportation, prevent container displacement and dumping, ensure the safety of cargo transportation, and greatly improve the stability and reliability of transportation.
