Supplements the subpart for tower cranes, to which all other sections apply unless stated otherwise. Sections 1926.1403 to 1926.1406 apply to erecting, climbing and dismantling, with those terms replacing assembly and disassembly. For self-erecting tower cranes, nobody may be inside or beneath the tower, jib or rotating portion during erecting, climbing or dismantling until the crane is locked and the competent person in charge says it is safe, unless the manufacturer's instructions say otherwise and only necessary personnel enter. Foundations and structural supports must have a design from the manufacturer or from a registered professional engineer, and the A/D director must confirm they are installed to design, address backward stability before swinging self-erecting or undercarriage-mounted cranes, and keep wind within the manufacturer's speed or a qualified person's figure, in addition to 1926.1404(h)(1) to (9). Towers must be plumb to the manufacturer's tolerance verified by a qualified person, or at least 1:500 (about 1 inch in 40 feet) if none is given. Fixed-jib cranes on one site must not be able to contact another crane's structure, though passing over is permitted. Before and during climbing the employer follows manufacturer prohibitions and has a registered professional engineer verify the host structure can carry brace, anchorage and floor forces. Counterweight and ballast amount and position follow the manufacturer or an RPE and are never exceeded. Sign size and location follow the manufacturer or an RPE's written approval. Safety devices (1926.1415 does not apply): boom and jib stops on luffing boom cranes, travel rail end stops and clamps, check valves on load-supporting cylinders, hydraulic pressure limiting device, hoist, swing, trolley and rail travel brakes that set automatically on pressure loss or power failure, deadman or forced neutral return levers, emergency stop at the operator's station, and trolley end stops; all must work, with no alternative measures. Operational aids (1926.1416 does not apply), with temporary alternatives while repaired. Category I, repaired within 7 calendar days (or 7 days of receiving parts documented as ordered within 7 days): trolley travel limiter (rope mark or spotter within 10 feet of end stops), boom hoist limiter, anti two-block device, hoist drum lower limiter on cranes made after November 8, 2011 (preventing the last 2 wraps spooling off), load moment limiter, hoist line pull limiter, rail travel limiter (spotter within 10 feet of rail end stops) and boom hoist drum positive locking control. Category II, repaired within 30 calendar days with the same parts exception: boom angle indicator on luffing cranes and hook radius indicator on hammerheads made after November 8, 2011, trolley, boom hoist and load hoist deceleration devices (alternative: posted cab notice), wind speed indicator mounted above the upper rotating structure or at or above jib level on self-erectors, and load indicating device on cranes made after November 8, 2011. Inspections: 1926.1412 (with erection replacing assembly) and 1926.1413 apply. Before erection a qualified person inspects each component for damage or wear, rejecting hazardous parts unless repaired and reinspected, and documents components to be watched in monthly inspections. After each erection a load test with certified weights, or weights scaled on a certified scale with a current calibration certificate, is run per the manufacturer or an RPE's written procedure. Monthly inspections add mast and structural bolts and the uppermost tie-in, braces, floor supports and wedges; annual inspections add all turntable and tower bolts for condition and torque.
