A high profile crane was exiting the Protected Area through Portal 33 at the Y-12 National Security Complex. While crossing the security barrier, the crane shifted slightly to the right and struck the barrier control box causing the box to fold inward. Approximately one ounce of hydraulic fluid was released to the ground. The slight acceleration to cross the security barrier caused bouncing of the crane suspension. The bouncing resulted in the cranes right rear outrigger frame coming in contact with the barrier control box.
Lessons Learned: Before moving high profile equipment, a careful examination of the travel path should be conducted. All areas of concern (i.e. such as having to cross a security barrier that might cause the equipment to bounce from side to side, the existence of obstructions or other hazards, should be addressed prior to moving the equipment.
