Every day, a competent worker shall, i. inspect all structural pins and keepers, ii. ensure all wedges in slab openings are in place and are tight, iii. ensure all guy lines and all guy line connections, if used, are adequate, iv. inspect mast bolts and anchor bolts, v. ensure all limit devices (except the line pull limit switch), signal lights, audio and visual indicators and brakes are operating correctly, vi. visually inspect all wire rope cable that winds on a drum or passes over a sheave that may reasonably be expected to be in use during the day’s operation of the tower crane for damage or possible evidence of rope failure, vii. inspect grounding connections, viii. inspect the tracks for loose connections, proper drainage, subsidence and bogie wear on travelling cranes, ix. inspect rail clamps, if used, daily or each time their application is made, and x. inspect the turn table bolts. 2. Every week, a competent worker shall inspect, i. all trolley rollers, tracks, slewing rings and rollers, ii. all gear shafts and belt drives, iii. all sheaves, bushings and pins, iv. all guy ropes, pendant lines, cable clips, thimbles and ferrules, v. all jib backstops and boom stops, vi. all rope attachments, vii. all walkways, handrails and ladders, viii. the locations in the structure where accumulation of water could result in damage, to ensure that such water is drained, ix. any tie-ins to slabs or other bracing systems that are used, and x. any other components recommended by the manufacturer. 3. Every month, a competent worker shall inspect, i. all running ropes, in accordance with clause 6.5.1.3. of CSA Standard Z248-17 for all types of deterioration, ii. all mast and boom structures for cracks or buckling, iii. travelling cranes for bogie wear, iv. counterweight supports, v. brake adjustments for wear, vi. drums, sheaves, bearings, and mounts, and vii. any other components recommended by the manufacturer.
