description abstract	Description of Driving Event: The 10-ton crane at the RTGF is used to lift and position radioisotope thermoelectric generators and ground support equipment. Crane electrical component failure increases the risk of load and/or crane damage. Failure of switches 3 or 4 results in bridge movement and bridge brake will not engage if a BR-1 relay failure occurs. Failure of switches 5 or 6 results in trolley movement and trolley brake will not engage if a BR-2 relay failure occurs. Failure of switches 7 or 8 results in hoist movement and hoist brake will not engage if a BR-3 OR BR-4 relay failure occurs. Failure of switch SW-2 in the fast speed position will result in the hoist operating in the fast speed even if the operator selects slow speed.
