Features

BoomThe 31,4 m (103 ft) four-section boom allows the operator to perform more lifts without the use of a jib, reducing setup time and improving efficiency.

Outriggers“A” frame main outriggers with 21 ft span. RSOD 16 ft out and down, rear stabilizers for standard behind-cab mount.

Two-speed auger optionAvailable on the 990A, the 14,000 ft/lb two-speed drive auger with a maximumdigging radius of 39 ft gives your crane enhanced working capabilities. Controls are located at the operator’s console and hose slider on boom. Auger flighting is available.

Easy Glide boom wear padsReduce the conditions that cause boom chatter and vibration resulting in smoother crane operation.
