§4965.1. Inspections.


(a) Article 100 (Inspection and Maintenance) applies to tower cranes, except that the term “assembly” is replaced by “erection.” Section 5036 (Inspection -- Wire Rope) applies to tower cranes.
(b) Pre-erection inspection. Before each crane component is erected, it shall be inspected by a qualified person for damage or excessive wear.
(1) The qualified person shall pay particular attention to components that will be difficult to inspect thoroughly during shift inspections.
(2) If the qualified person determines that a component is damaged or worn to the extent that it would create a safety hazard if used on the crane, that component shall not be erected on the crane unless it is repaired and, upon re-inspection by the qualified person, found to no longer create a safety hazard.
(3) If the qualified person determines that, though not presently a safety hazard, the component needs to be monitored, the employer shall ensure that the component is checked in the periodic inspections. Any such determination shall be documented, and the documentation shall be available to any individual who conducts a periodic inspection.
(c) Post-erection inspection. In addition to the requirements in Section 5031.1, the following requirements shall be met:
(1) A load test using certified weights, or scaled weights using a certified scale with a current certificate of calibration, shall be conducted after each erection.
(2) The load test shall be conducted in accordance with Sections 344.81, 5022 and the manufacturer's instructions.
(d) Periodic inspection. The following additional items shall be included:
(1) Tower (mast) bolts and other structural bolts (for loose or dislodged condition) from the base of the tower crane up or, if the crane is tied to or braced by the structure, those above the upper-most brace support.
(2) The upper-most tie-in, braces, floor supports and floor wedges where the tower crane is supported by the structure, for loose or dislodged components.
(e) Annual inspection. In addition to the items that shall be inspected under Sections 5022(d), 5031(d), and 5031.1, all turntable and tower bolts shall be inspected for proper condition and torque.
