Modified equipment: after modifications or additions that affect safe operation or capacity (safety devices, operational aids, critical control parts, power plant, brakes, load-sustaining structure, load hook or in-use operating mechanisms), a qualified person must inspect it before first use, confirming the work matches the 1926.1434 approval and including functional testing; no use until that is shown. Repaired or adjusted equipment: a qualified person inspects before first use, checking the repair against manufacturer criteria, or where none apply, deciding whether a registered professional engineer must write criteria (otherwise the qualified person writes them) and checking against them, with functional testing of the repaired parts and anything they affect. Post-assembly: a qualified person confirms configuration matches manufacturer criteria, or criteria developed by a qualified person or RPE where the manufacturer's are unavailable; no use until then. Each shift: a competent person starts a visual check before every shift the equipment is used, finishing before or during the shift, looking for apparent deficiencies without disassembly or booming down unless findings call for it, and reassessing during operation. Items: control mechanisms, control and drive wear and contamination, pressurised lines, hydraulic fluid level, hooks and latches, wire rope reeving, wire rope per 1926.1413(a), electrical apparatus, tyres, ground conditions (not FRA-regulated track), level within manufacturer tolerance, checked at shift start and again after every move and set-up, cab windows, rails and stops (not FRA-regulated track), and safety devices and operational aids. A deficiency that the competent person judges a safety hazard takes the equipment out of service until corrected; device and aid deficiencies follow 1926.1415 and 1926.1416. Monthly: each month in service the shift inspection is performed, the equipment is not used until no corrective action is outstanding, and the employer doing the inspection documents items checked, results, the inspector's name and signature and the date, keeping it at least three months. Annual/comprehensive: at least every 12 months a qualified person does the shift items plus a detailed check, with disassembly as needed, of structure (members, fasteners, welds), sheaves and drums, pins, bearings, shafts and gears, brakes and clutches, safety devices and aids for accuracy, power plants, chains and sprockets, travel steering and brakes, tyres, hoses and fittings, pumps and motors, valves, cylinders, outrigger pads, slider pads, electrical wiring, warning labels, operator seat, and steps, ladders, handrails and guards, plus functional testing. Hazards take the equipment out of service unless temporary alternative measures under 1926.1416(d) or under 1926.1435(e) are used; items to watch go on the monthly checks. Documentation (items, results, name, signature, date) is kept at least 12 months. Severe service (possible overload, shock loading, prolonged corrosive exposure) requires stopping use and a qualified person's structural inspection and any needed annual items. Equipment idle 3 months or more gets a monthly-type inspection by a qualified person before use. More comprehensive or frequent manufacturer inspection requirements must be followed, and all inspection documents must be available to every inspector during the retention period.
