Tower Crane Erection & Section Climbing Inspection Checklist

Verify all mast sections are free from damage (dents, bends, corrosion) prior to assembly. Document findings with photos.

Confirm that all bolts are of the correct grade and length as specified by the crane manufacturer's manual. Check against parts list.

Inspect the slewing ring for any signs of wear, cracks, or damage. Check lubrication points and grease levels.

Examine all hydraulic hoses for cuts, abrasions, kinks, or leaks. Ensure hoses are properly rated for the system pressure.

Assess the climbing frame for structural integrity, proper alignment, and secure locking mechanisms. Verify all pins and locking devices are in place.

Verify the counter-jib is properly secured and that all counterweights are correctly installed and locked in place. Check locking pins.

Inspect all wire ropes for wear, broken strands, corrosion, and proper lubrication. Document findings and replace if necessary.

Check all electrical connections for tightness, proper insulation, and grounding. Verify wiring diagrams are available and accurate.

Confirm all lubrication points are accessible and properly greased according to the manufacturer's specifications. Document lubrication schedule.

Test all safety devices, including limit switches, overload protection, and anti-collision systems. Document test results.

Verify the torque wrench is calibrated and within its calibration period. Check calibration certificate.

Confirm the correct bolt tightening sequence is followed as per the manufacturer's instructions. Use a documented procedure.

Verify each bolt is torqued to the specified value using a calibrated torque wrench. Record torque values for each bolt.

Inspect bolt threads for damage or contamination before tightening. Clean and lubricate threads as necessary.

Ensure washers are correctly placed under bolt heads and nuts to distribute load evenly. Verify correct washer type.

Implement a re-torque procedure after the initial tightening to account for settling. Document re-torque values.

Visually inspect all bolts after torquing to ensure proper seating and no signs of thread stripping. Document observations.

Verify that locking mechanisms (e.g., lock washers, cotter pins) are properly installed to prevent loosening. Check security.

Maintain a detailed record of all torque values for each bolt, including date, time, and personnel performing the task.

Check that the bolt protrusion length after tightening meets the manufacturer's specifications. Too little or too much protrusion can indicate issues.

Monitor hydraulic pressure during the climbing process to ensure it remains within the manufacturer's specified range. Record pressure readings.

Verify the cylinder stroke length is consistent and within the specified limits during each climbing cycle. Measure stroke length.

Check the hydraulic fluid level in the reservoir before and after each climbing operation. Top off as needed with correct fluid type.

Inspect all hydraulic connections, hoses, and cylinders for leaks during and after the climbing process. Repair leaks immediately.

Listen for unusual noises from the hydraulic pump during operation. Unusual noises can indicate cavitation or other problems.

Verify that all hydraulic valves are operating smoothly and correctly. Check for sticking or binding.

Test the emergency stop function of the hydraulic system before each climbing operation. Ensure it immediately halts the process.

Monitor for cylinder drift during pauses in the climbing process. Excessive drift indicates internal leakage.

Check the condition of the hydraulic filters and replace them according to the manufacturer's recommendations. Document filter changes.

Monitor the temperature of the hydraulic fluid during operation. Overheating can damage components.

Verify the anemometer is calibrated and functioning correctly. Check calibration date.

Continuously monitor wind speed at the crane's operating height using a calibrated anemometer. Record wind speed readings.

Establish and follow a clear shutdown procedure when wind speeds exceed the crane manufacturer's specified limits. Document procedure.

Monitor weather forecasts for impending storms or high winds. Plan work accordingly.

Ensure the crane is free to weathervane (rotate freely) when out of service to minimize wind resistance. Check slewing ring brake release.

Implement a tie-down procedure for the crane during periods of high winds or when the crane is out of service for extended periods. Document procedure.

Assess visibility conditions before starting work. Ensure adequate visibility for safe crane operation. Stop work if visibility is impaired.

Verify the crane is properly grounded to protect against lightning strikes. Check grounding connections.

Consider the effects of extreme temperatures (hot or cold) on crane components and hydraulic systems. Adjust procedures accordingly.

Establish a clear communication protocol for notifying personnel of changing weather conditions and implementing shutdown procedures.

Verify that all personnel involved in the erection and climbing process are properly trained and certified. Check training records.

Inspect all fall protection harnesses for damage, wear, and proper fit before each use. Remove damaged harnesses from service.

Inspect all lanyards and self-retracting lifelines (SRLs) for damage, wear, and proper functionality. Remove damaged equipment from service.

Ensure all personnel are wearing properly fitted hard hats that meet ANSI Z89.1 standards. Check for damage.

Ensure all personnel are wearing safety glasses or face shields to protect against flying debris. Verify compliance.

Ensure all personnel are wearing high-visibility clothing (e.g., vests, jackets) that meet ANSI 107 standards. Check for cleanliness.

Verify that all personnel have reliable communication equipment (e.g., radios) and that communication protocols are established and understood.

Ensure all tools and equipment used at height are properly tethered to prevent dropped objects. Inspect tethers for damage.

Verify that personnel are wearing appropriate gloves for the task being performed. Check glove condition.

Ensure all personnel are wearing appropriate safety footwear that meets ASTM F2413 standards. Check for damage.
