§4960.1. Operational Aids (Supplemental requirements for derricks in construction).

(a) Section 5018, Operational Aids, applies, except as supplemented below:

(b) Boom angle aid. A boom angle indicator is not required but if the derrick is not equipped with a functioning one, the employer shall ensure that either:

(1) The boom hoist cable shall be marked with caution and stop marks. The stop marks shall correspond to maximum and minimum allowable boom angles. The caution and stop marks shall be in view of the operator, or a spotter who is in direct communication with the operator; or

(2) An electronic or other device that signals the operator in time to prevent the boom from moving past its maximum and minimum angles, or automatically prevents such movement, is used.

(1) Derricks manufactured more than one year after July 7, 2011, with a maximum rated capacity over 6,000 pounds shall have at least one of the following: load weighing device, load moment indicator, rated capacity indicator, or rated capacity limiter.

Temporary alternative measures: The weight of the load shall be determined from a source recognized by the industry (such as the load's manufacturer), or by a calculation method recognized by the industry (such as calculating a steel beam from measured dimensions and a known per foot weight), or by other equally reliable means. This information shall be provided to the operator prior to the lift. See Section 5008.1(g) for additional requirements.

(2) A load weight/capacity device that is not working properly shall be repaired no later than 7 calendar days after the deficiency occurs.
