 | Boom | 12 m - 47 m five-section full-power boom, sequenced synchronized, full-power boom with three operator selectable modes of extension and retraction. Any mode can be enabled or disabled to offer all modes or limited mode depending on user or application usage. Maximum tip height: 50 m |
| *Optional manual bi-fold swingaway extension | 10 m - 17 m bi-fold lattice swingaway extension. Offsettable at 0°, 20°, and 40°. Stows alongside base boom section. Electric motor assist for stowing and pin alignment.Maximum tip height: 67 m | |
| *Optional hydraulic bi-fold swingaway extension | 10 m - 17 m bi-fold lattice swingaway extension. Hydraulic luffing offset from 0° to 40°. Stows alongside base boom section. Electric motor assist for stowing and pin alignment. Maximum tip height: 67 m | |

| Crane Control System (CCS) | "Graphic Display" RCL load moment and anti-two block system with audio-visual warning and control lever lockout. This system provides electronic display of boom angle, boom length, load radius, boom tip height, maximum permissible load, actual load and warning of impending two-block condition. The work area definition system allows the operator to pre-select and define safe working areas. If the crane approaches the pre-set limits, audio-visual warnings aid the operator in avoiding job site obstructions. | |
