Some excavators come with a knuckle boom. This kind of boom is more flexible than the first one because it can move right and left in line with the excavator. This is the better choice than the first one.

The third type is hinged boom. This boom is more flexible than excavator mono boom and knuckle boom. This one has a hinge at the boom base. The hinge allows it to pivot up hydraulically to 180 degrees independent to the house. This type of boom is commonly available on compact excavators only. Another type is triple-articulated boom (TAB). Even though it is rare, sometimes an excavator with this type of boom is needed in a project.
