In the past, when it comes to matters concerning safety, many workers are frowning upon the use of a lifeline that self-retract, and that is not because they do not appreciate its function, but it is because these tools are very heavy, big, and bulky. As time passes by, things started to change. Technological improvements have led to enhancement of materials and equipment. Albeit the fact that troublesome clunkers are still around and serving their purpose, lots of lifelines that self-retract have become more moveable, weigh up a little as a few pounds. The earlier nicknames given to lifelines that self-retract (such as yo-yo) are quite misleading in the way they function. The thing is that self retracting lifeline work similarly as seatbelts of car work. When a particular level of force or speed is achieved, it will cause a mechanism for locking to engage, arresting the forward movement of a passenger car (in the circumstance of seatbelts), or perhaps, the downward movement of a person falling (in the situation of lifelines that self-retract). As a way of seeing how such tool works is quite simple. First, you have to take your lifeline that self-retract and place it in both hands. Next, pull the webbing or the cable out as slowly as you can. By doing this slowly, it will cause the tool to continuously stretch until it touches its full length. Then, let the device retract. Now, you have to snap the webbing or the cable out. When you pull the device hardly, you will see it locking itself into place. Follow these steps and you will be able to effectively make use of your self retractable lifelines. Another thing about a lifeline that self-retract that you have to know of is that it is made of several parts. The casing or the housing is the fragment that you see the most. It’s the metal or the plastic enclosure which contains almost all parts of the device, together with the mechanism for locking. The next part of a lifeline that self-retracts is the drum. The drum is the thing that the lifeline gusts on to. Then we have the shaft, which usually comes in the form of a rod made of steel. It is located at the center which the cask rotates. Then we have the mechanism for locking, which comprises of the spring motor that retains pressure on the lifeline when stretched out. Finally, the lifeline which has a snap hook for attachment. All in all, a lifeline that self-retract is very efficient in ensuring a person’s safety, especially when working at high-risk places.
