Why is the actual weight of the differential anti fall device lighter than the standard weight

Many people judge the quality of a speed differential anti fall device based on its appearance, the roughness of the steel wire rope, and the luster of the hook and loop. However, in reality, we can also judge its quality based on its own weight.

We can use a human scale to weigh the newly purchased anti fall device and see if there is a discrepancy between the actual weight of the anti fall device and the standard product weight stated in the manual. If the weight is much lighter, it indicates that the manufacturing materials of the anti fall device have been cut corners. In actual use, its load-bearing capacity will also be greatly reduced, and the safety factor will be greatly lowered. If the weight is relatively heavy or the value is equivalent, it indicates that there is no problem with the materials used for this anti fall device.

In the specification and model table of the speed difference anti fall device, we can see that the self weight of a 3-meter anti fall device is 1.8KG, a 5-meter anti fall device is 2KG, a 7-meter anti fall device is 3.2KG, a 10 meter anti fall device is 3.5KG, a 15 meter anti fall device is 4.8KG, a 20 meter anti fall device is 6.5KG, a 30 meter anti fall device is 12.5KG, a 40 meter anti fall device is 23KG, and a 50 meter anti fall device is 30.7KG.
