Have the crane operator confirm that the proper recommended tires are fitted (sand tires are not acceptable) and that tires have no obvious defects and are at the manufacturer’s recommended tire pressure.

Have the on rubber and pick and carry lift duties stated on the manufacturer’s crane load chart for this duty to be an acceptable option.Have proper lighting, sufficient to perform the lift safely.Have specific prior written approval from Project Management for each crane lift performed at night.Have an approved Critical Lift Plan on site prior to each crane lift performed at night (between sunset and sunrise).Have prior written approval from the Project Management for crane suspended personnel platform operations that are performed at night. Not perform crane suspended personnel platform lifts in wind speeds exceeding 25 km/h (15 mph – 13 knots – 7 meters/second). Have a Crane Suspended Personnel Platform Permit properly completed, signed, and onsite prior to the lift.ĭe-rate the crane by 50% of the load chart. 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.
