When returning the source (Ir-192, 108 curies) the locking bar deployed prematurely. The crew reset the locking bar and was able to return the source to the safe and secure position. The crew was working a remote location using a Tucker (tracked machine for traveling over snow) and called for the night foreman. They met at a drill site where the exposure device was reconnected to the drive cables. The source was extended and then retracted. It was noticed that on the return the crank assembly became hard to turn. After the locking bar tripped, the exposure device was surveyed with no noticeable indication that the source was not in the safe and secure position. When the crank assembly was disconnected it was noted that the pig tail was not in its proper position. The exposure device was transported back to the main office. | When returning the source (Ir-192, 108 curies) the locking bar deployed prematurely.
