Boom The four-section boom allows the operator to perform more lifts without the use of a jib, reducing setup time and improving efficiency.

Two-speed auger option The 14,000 ft. /lb. two-speed drive auger with a maximum digging radius of 39 ft. gives your crane enhanced working capabilities. Controls are located at the operator’s console and hose slider on boom. Auger fighting is available.
