Have an approved Critical Lift Plan on site prior to the lift. Only allow work from, or transport by, a crane suspended personnel platform when conventional means of performing the work or reaching the work site would be more hazardous, or is not practical, because of structural design or work site conditions. Have a separate, approved Critical Lift Plan on site prior to the lift, each time one of these types of lifts is performed. Utilize cranes of same size, manufacturer, and model, if possible, (except tailing lift) for tandem (multiple), and turning lifts. Tailing lifts, tandem (multiple cranes), or turning lifts:ĭe-rate all cranes involved in the lift by 25% of the load chart. Special critical crane lifts, hazardous by their nature and requiring special training, rigging, and/or boom attachments, include, but are not limited to, the following examples and requirements:.When working less than 1-1/2 fully extended boom lengths from energized power lines,a designated signalman shall ensure the minimum distances. Note: No lifts are permitted that exceed 95% of the load chart for any given configuration of the crane.Īny part of a crane whose boom or boom attachment is working within 6 meters (20 ft) of any energized power-lines. Any load that exceeds 75% of the crane’s rated load capacity or manufacturer’s specifications for a specific lift.Any crane lift that requires an attachment(s) to the main boom.
