    SUSPENDING LOADS OVER PEOPLE

    The suspension of loads over people demands the highestlevel of rigging knowledge, equipment, and equipmentmaintenance.The ShowPro must be installed and used inaccordance to rigorous rigging standards required whensuspending loads over people.These include the following

    important precautions.1. It is preferred that the load always be tied off with auxiliary

    chains or cables before access to the area beneath the loadis permitted. As an alternative, the system may be designedsuch that malfunction or failure of one hoists load bearingcomponents does not cause load loss and/or overloading ofany other hoists in the system. Note that in such a system,hoist performance and function must be monitored visuallyor with the use of load cells.

    2. Never operate the lifting motor while people are underthe load.

    SAFETY INFORMATION

    1. Follow all local electrical and safety codes, as well as theNational Electrical Code (NEC) and the OccupationalSafety and Health Act (OSHA) in the United States.

    2. The lifting motor must be securely and adequatelygrounded. The lifting motor control cable includes agreen/yellow wire for ground and is equipped with aconnecting plug that includes a prong for ground.

    3. Be careful when touching the exterior of an operatingmotor; it may be hot enough to be painful or cause injury.With modern motors this condition is normal if operated atrated load and voltage (modern motors are built to operateat higher temperatures).

    4. Protect the power cable from coming in contact with sharpobjects.

    5. Do not kink power cable and never allow the cable to comein contact with oil, grease, hot surfaces, or chemicals.
