The crane rigger should have rigged similar cranes to the one you will be hiring in the past. Contact the rigger's references. Other than confirming that the rigger is experienced, inquire about their general conduct at the site. For example, can the individual keep time? Does the rigger have excellent leadership and communication skills? Remember, he or she will guide employees at the site.
