If the boom length, lift angle, and lift weight are not measured properly, the crane may fail. An experienced crane engineer can interpret these factors in light of present circumstances to determine the viability of a given lift. Most load charts include sections on boom length, boom angle, and lift range in addition to information on other important variables. It gives a brief overview of the crane’s capabilities and goes over the cranes’ features and characteristics, including the loads it can handle given certain specifications - lift height, lift angle, etc.

Simply put, a load chart is a summary of what a crane can and cannot do.

There are all-terrain cranes, prized for their versatility, as well as rough terrain cranes, built for rugged worksites. The sheer number of cranes available can make selecting the right one for the job intimidating.

Today, the crane industry - employing thousands of people - is worth billions of dollars.Ĭranes are very complex machinery that incorporate some of the latest technology, and operating a crane is no rudimentary task, as it requires a good deal of training and know-how - not to mention a steady hand.Ĭranes are used in a variety of different industries, creating a robust rental market.
