Cranes has existed for a very long time and it continues to serve its purpose of lifting heavy objects up until the present. It is amazing to think that cranes of long ago were just made out of wood and powered by beasts of burden and or man. Then as time went by, cranes were eventually integrated into stone towers which are used to lift heavy loads unto ships. It was not long when cranes have been reinforced by iron and steel which further made them effective when it comes to lifting heavier loads.
Cranes come in various forms and functions. One is called the jib crane. A jib crane is often used inside warehouses and workshops. Compared to other cranes, a jib crane is smaller but a sturdy foundation is still necessary to support the whole mechanism. But what makes it valuable is that it can be made into a portable jib crane and it can cover more areas thanks to its ability to rotate. Unlike others which are limited to lateral horizontal motion on a cross beam, a jib crane is more flexible.
There are also different kinds of jib cranes. There are cranes which are mounted on a steel column. And these comes into two sub-categories: The tie-rod jib which have a greater reach but can only be raised on a certain height and the wall-cantilever jib which is more expensive but can lift loads in a higher position. Unfortunately, the wall-cantilever jib lacks reach and a tie-rod jib is often preferred by construction staff due to its affordability.
Man’s innovation does not know any limits and it is only a matter of time before he is able to improve the various crane designs available.
