Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) The
						requirements of this Article shall apply to cranes of the general type such as
						those having a revolving boom with counterweight on a single vertical mast, and
						mobile tower cranes.
(b) Each crane
						shall be provided with a descriptive booklet, written in English, containing a
						comprehensive summary of design characteristics, erection procedures, operation
						techniques, repair recommendations, and safety precautions. This booklet shall
						be available on every job site where such cranes are in use.
(c) A durable, clearly legible load rating
						chart shall be provided with each crane and securely affixed in the cab or
						operator's station easily visible to the operator while at the controls. The
						chart shall include load ratings and restrictions as specified by the certified
						agent for specific lengths of components, counterweights, swing, and radii.
						Where load ratings for cranes are governed by structural competence, the
						limitation on loading shall be such that no structural member is overstressed,
						and load rating charts shall be subject to this limitation.
(d) Each crane shall be equipped with a
						device which will effectively prevent overloading beyond the certified agent's
						recommendations at any load, boom radius, and counterweight position.
(e) Each crane shall contain a means which
						will cause the boom swing to be started and stopped gradually to prevent
						damaging effects of torsion in the mast section.
(f) Each crane shall be equipped with a brake
						system, or equivalent, which will prevent any movement when the power is lost,
						or at any time desired by the operator.
(g) Parts of the crane requiring adjustment
						or maintenance shall be provided with access walkways, handholds, footholds,
						safety lines, or other safeguards as necessary to eliminate the hazard of
						falling from the crane.
EXCEPTION: Mobile tower crane adjustment or maintenance
						  that can be achieved from the ground.
(h) Signs. The size and location of signs
						installed on tower cranes shall be in accordance with manufacturer
						specifications. Where these are unavailable, a certified agent familiar with
						the type of equipment involved shall approve in writing the size and location
						of any signs.
(i) Cranes shall be
						tested, maintained, inspected, and operated as specified by the certified agent
						and these Orders. Luffing boom tower cranes used in the construction industry
						shall comply with the requirements of ASME B30.3-1990, Hammerhead Tower Cranes,
						herein incorporated by reference.
(j)
(1) If
						a tower crane remains on a project over twelve months, tests required by
						subsection (i) of this section shall be performed following dismantling and
						prior to its next use.
(2) Records
						of the most recent nondestructive tests and the test procedures shall be
						maintained by the owner of the crane and provided to the Division upon
						request.
