The classic example for the superiority of an articulated boom is a 2 story house with a front porch that has a roof. Your job in this example is to change the windows on the second floor. If you have a straight boom (picture one long arm) you have to sit a distance away from the porch to get the angles right. If you sit too close you’ll either be too high over the windows or worse you’ll lower the boom down and hit your porch roof. With the articulated boom you can put the lower riser boom up first. Now you’re pivot point is higher and you’ll be able to drive much closer to the porch and still reach those windows. Basically the articulated boom got rid of your angle issue.

If this was the end of the story the answer would be easy but it’s not. If you’re looking for the maximum horizontal reach a straight boom reaches farther. The reason for this is that on an articulated boom the lower/riser boom only gives height, not reach forward. Using 60 ft booms as an example a straight 60 ft boom reaches to the side about 50 ft. An articulated 60 ft boom reaches about 40 ft to the side. Often times this extra horizontal reach is just as important as the improved angles the articulated boom allows.

Additionally in terms of ownership articulated booms tend to be a little more expensive in terms of maintenance because they have more moving parts. Lastly for lifts 45 ft and smaller articulated booms usually have basket sizes of 6 ft maximum versus 8 ft for straight booms which can be important for certain applications.
