Description

Technical field [0001] The invention relates to a device for monitoring the tension of steel wire ropes for cargo binding, which uses a piezoelectric effect mechanism to trigger, especially a device that can identify safe and dangerous tension changes. Background technique [0002] A large number of steel wire ropes are used in the cargo binding process. After repeated use, the steel wire ropes will be worn and deformed, and their carrying capacity will change. Whether the steel wire rope is tensioned during lashing or not can only be checked visually or based on experience, which can easily lead to inconsistent loads on various parts of the steel wire rope. At the same time, a slight change in the posture of the vehicle during transportation will lead to a drastic change in the tension of the steel wire rope, thereby affecting the safety of cargo transportation. Hidden danger. In order to avoid causing heavy losses, there is an urgent need for a device to grasp the tension...
