– There are four lifting mechanisms that form clouds: Orographic Lifting, Convection, Convergence, and Updraft. – Orographic lifting is when air cannot go through a mountain, and so it flows over it. – Frontal Lifting is when less dense warm air is forced to rise over cooler, denser air as a weather fronts move.

Basket Hitching – This method is where each end of the sling is secured to the crane's hook. It helps prevent added tension on the load. Depending on the size of the object being lifted, a single or double wrap sling configuration could be used. However, this method is not so great to use for objects that are hard to keep balanced.
