Mobile Crane Operator

Written Exam - Telescopic Boom Crane-Fixed Cab (TSS)

These sample questions are intended to convey something of the style and content of the Crane Operator Certification Program written examinations developed and administered by the National Commission for the Certification of Crane Operators (NCCCO). They are not actual test questions, nor do they attempt to address all of the areas of knowledge tested on the CCO certification examinations. Response to these questions is not necessarily an indication of performance on the CCO examinations.
