Example embodiments relate to a lightweight crane. In one nonlimiting embodiment the crane is comprised of a telescoping boom having a first boom nested in a second boom which in turn is nested in a third boom. The first, second, and third booms may be made from aluminum to reduce the weight of the crane. The first boom may have a first open section and a second closed section wherein the open section is configured to accommodate a structural member to which an actuator is attached. The first and second booms have lower surfaces with inclined surfaces so that the first boom self-aligns with the second boom and the second boom self-aligns with the third boom.
