Crane Assisted Rigging Removal

Crane Assisted Rigging and removal (CARR) 3-Day Course

This course is for professionals who have primary roles in arboricultural tree removal that utilize cranes and rigging to safely perform their jobs. It is designed for climbers and ground workers, and their various roles and responsibilities on jobsites. Through our CARR course, participants will learn the safe use of mobile cranes when used on an arboricultural worksite. Emphasis on current OSHA and ANSI regulations will be taught throughout the class.

Education, coaching, and practical hands-on experience using compound rigging strategies and setting safe and proper rigging to balance pieces will be explained and demonstrated. Additionally, safe setup of the crane and all required safety measures such as proper outrigger placement, understanding load charts and lifting angles, estimating green log, tree-part weights, and proper cuts to use when working with a crane will also be explained and demonstrated.
