§1615.2. Operational Aids.

(a) The devices listed in this section (“listed operational aids”) are required on all equipment covered by Article 15, unless otherwise specified.

(1) The requirements in subsections (e)(1), (e)(2), and (e)(3) do not apply to articulating cranes.

(2) The requirements in subsections (d)(3), (e)(1), and (e)(4) apply only to those digger derricks manufactured after July 7, 2012.

(b) Operations shall not begin unless the listed operational aids are in proper working order, except where an operational aid is being repaired the employer uses the specified temporary alternative measures. The time periods permitted for repairing defective operational aids are specified in subsections (d) and (e).

More protective alternative measures specified by the crane/derrick manufacturer, if any, shall be followed.

(c) If a listed operational aid stops working properly during operations, the operator shall safely stop operations until the temporary alternative measures are implemented or the device is again working properly.

(d) Category I operational aids. Operational aids listed in this section that are not working properly shall be repaired no later than 7 calendar days after the deficiency occurs.

Exception: If the employer documents that it has ordered the necessary parts within 7 calendar days of the occurrence of the deficiency, the repair shall be completed within 7 calendar days of receipt of the parts. See Section 1616.1(j) for additional requirements.

(1) Boom hoist limiting device.

(A) For equipment manufactured after December 16, 1969, a boom hoist limiting device is required.

Temporary alternative measures (use at least one). One or more of the following methods shall be used:

1. Use a boom angle indicator.

2. Clearly mark the boom hoist cable (so that it can easily be seen by the operator) at a point that will give the operator sufficient time to stop the hoist to keep the boom within the minimum allowable radius. In addition, install mirrors or remote video cameras and displays if necessary for the operator to see the mark.

3. Clearly mark the boom hoist cable (so that it can easily be seen by a spotter) at a point that will give the spotter sufficient time to signal the operator and have the operator stop the hoist to keep the boom within the minimum allowable radius.

(B) If the equipment was manufactured on or before December 16, 1969, and is not equipped with a boom hoist limiting device, at least one of the measures in subsections (d)(1)(A)1-3 shall be used.

(2) Luffing jib limiting device.

Equipment with a luffing jib shall have a luffing jib limiting device.

Temporary alternative measures are the same as in subsection (d)(1)(A), except to limit the movement of the luffing jib rather than the boom hoist.

(3) Anti two-blocking device.

(A) Telescopic boom cranes manufactured after February 28, 1992, shall be equipped with a device which automatically prevents damage from contact between the load block, overhaul ball, or similar component, and the boom tip (or fixed upper block or similar component). The device(s) shall prevent such damage at all points where two-blocking could occur.

(B) Lattice boom cranes.

1. Lattice boom cranes manufactured after Feb 28, 1992, shall be equipped with a device that either automatically prevents damage and load failure from contact between the load block, overhaul ball, or similar component, and the boom tip (or fixed upper block or similar component), or warns the operator in time for the operator to prevent two-blocking. The device shall prevent such damage/failure or provide adequate warning for all points where two-blocking could occur.

2. Lattice boom cranes and derricks manufactured after July 7, 2012 shall be equipped with a device which automatically prevents damage and load failure from contact between the load block, overhaul ball, or similar component, and the boom tip (or fixed upper block or similar component). The device(s) shall prevent such damage/failure at all points where two-blocking could occur.

Exception: The requirements in subsection (d)(3)(B) do not apply to such lattice boom equipment when used for dragline, clamshell (grapple), magnet, and drop ball work.

(C) Articulating cranes manufactured after December 31, 1999, that are equipped with a load hoisting device (winch) shall be equipped with a device that automatically prevents damage from contact between the load block, overhaul ball, or similar component, and the boom tip (or fixed upper block or similar component). The device shall prevent such damage at all points where two-blocking could occur.

(e) Category II operational aids and alternative measures. Operational aids listed in this subsection that are not working properly shall be repaired no later than 30 calendar days after the deficiency occurs.

Exception: If the employer documents that it has ordered the necessary parts within 7 calendar days of the occurrence of the deficiency, and the part is not received in time to complete the repair in 30 calendar days, the repair shall be completed within 7 calendar days of receipt of the parts. See Section 1616.1(j) for additional requirements.

(1) Boom angle or radius indicator. Cranes shall be provided with a boom angle or radius indicator which clearly shows the boom angle in degrees to the operator at all times.

Exception: When a boom angle or radius indicator is inoperative or malfunctioning, a qualified person shall determine the radius or boom angle by measurement until the indicator is restored to operation.

(A) Boom angle or radius indicators shall be repaired in accordance with the manufacturer's recommendations.

(2) Jib angle indicator if the equipment has a luffing jib.

Temporary alternative measures: Radii or jib angle shall be determined by a qualified person ascertaining the main boom angle and then measuring the radii or jib angle with a measuring device.

(A) Jib angle or radius indicators shall be repaired in accordance with the manufacturer's recommendations.

(3) Boom length indicator if the equipment has a telescopic boom, except where the rated capacity is independent of the boom length.

Temporary alternative measures. One or more of the following methods shall be used:

(A) Mark the boom with measured marks to calculate boom length,

(B) Calculate boom length from boom angle and radius measurements,

(C) Measure the boom with a measuring device.

(4) Load weighing and similar devices.

(A) Equipment (other than derricks and articulating cranes) manufactured after March 29, 2003 with a rated capacity over 6,000 pounds shall have at least one of the following: load weighing device, load moment (or rated capacity) indicator, or load moment (or rated capacity) limiter.

Temporary alternative measures: The weight of the load must 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). This information must be provided to the operator prior to the lift.

(B) Articulating cranes manufactured after July 7, 2012 shall have at least one of the following: automatic overload prevention device, load weighing device, load moment (or rated capacity) indicator, or load moment (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). This information shall be provided to the operator prior to the lift.

(5) The following devices are required on equipment manufactured after July 7, 2012:

(A) Outrigger/stabilizer position (horizontal beam extension) sensor/monitor if the equipment has outriggers or stabilizers.

Temporary alternative measures: The operator shall verify that the position of the outriggers or stabilizers is correct (in accordance with manufacturer procedures) before beginning operations requiring outrigger or stabilizer deployment.

(B) Hoist drum rotation indicator if the equipment has a hoist drum not visible from the operator's station.

Temporary alternative measures: Mark the drum to indicate the rotation of the drum. In addition, install mirrors or remote video cameras and displays if necessary for the operator to see the mark.
