Inspects hardware, slings, and rigging equipment before each use and understands the criteria for their removalSelects the proper hardware and equipment for various hoisting operations while compensating for different crane, environmental, and job site conditionsProperly accounts for the effects and limitations of hitch configurations and calculates sling stress on symmetrical loads using the appropriate formulasKnowledgeable about and performs proper hardware installation and attachment techniquesCommunicates movements to crane operator using the appropriate voice or hand signalsTakes into account the effect of voice or hand signals on the load and the craneRecognizes hazards (e.g., extreme angles, pinch points, criteria for critical hoist)Adjusts for the gross weight of the load in hoisting operationsDetermines the load weight and center of gravity of symmetrical loads accuratelyTakes into account how shifting centers of gravity affect load stabilityIdentifies proper attachment points based on center of gravity and hitch configurationDetermines types of knot to use based on material and application
