The CRS program focuses on the knowledge and skills necessary to maintain safe working environments during basic rigging and signaling operations. The CRS designation indicates competence in the following areas:
Inspects hardware, slings, and rigging equipment
Selects the proper hardware for hoisting operations (e.g., takes into account the effect of friction on synthetic slings or hardware)
Accounts for the effect of the configuration on the sling stress
Performs proper hardware installation and attachment techniques
Communicates movements to crane operator using the appropriate voice or hand signals
Takes into account the effect of voice or hand signals on the load and the crane
Recognizes hazards (e.g., extreme angles, pinch points, criteria for critical hoist)
Adjusts for the gross weight of the load in hoisting operations
Determines the load weight and center of gravity of symmetrical loads accurately
Takes into account how shifting centers of gravity affect load stability
Identifies proper attachment points based on center of gravity and hitch configuration
Determines types of knot to use based on material and application
