Task E-11 Performs pre-lift planning
Task descriptor
Mobile crane operators coordinate lift responsibilities with crew members and other tradespeople at pre-lift meetings. This is a crucial step in planning lifts.
Pre-lift plans can run from a brief informal plan to a detailed process involving many parties such as companies, engineers, customers and sub-contractors.
