Cranes and crane systems with high capacity lifting capabilities, as well as versatility and relatively large operational areas. A crane of the present disclosure may have main boom pivotable about a substantially horizontal axis and a luffing assembly configured for luffing the boom about the axis. The main boom may be pivotable in both a forward luffing operation and a reverse or rearward luffing operation. In this way, the main boom may be operable within a range extending up to 180 degrees. Various adjustment mechanisms may be used to shift the main boom from a forward luffing operation to a reverse luffing operation. Additionally, a crane of the present disclosure may have a utility boom rotatable about a substantially vertical axis. The utility boom may allow for added lateral reach of the crane, thus further increasing the operational area of the crane.
