Section 4968.2 - Operational AIDS(a) Section 5018 does not apply to tower cranes.(b) The devices listed in this section ("operational aids") are required on all tower cranes covered by Group 13, unless otherwise specified.(c) Operations shall not begin unless the operational aids are in proper working order. If a listed operational aid stops working properly during operations, the operator shall safely stop operations until the device is repaired, or the device is again working properly. (1) Any replacement part or device utilized shall perform the same type function as permitted subject to the provisions of Section 4884.1.(2) See Section 5008.1(g) for additional requirements.(3) Temporary operations are permitted where the employer meets the specified temporary alternative measures; however more protective alternative measures specified by the tower crane manufacturer, if any, shall be followed.(d) Operational aids and alternative measures. Operational aids listed in this section that are not working properly shall be repaired no later than 7 calendar days after the deficiency occurs subject to the provisions of subsection (c). (1) Hoist drum lower limiting device. Tower cranes manufactured after July 7, 2012, shall be equipped with a device that prevents the last 2 wraps of hoist cable from being spooled off the drum. Temporary alternative measure: Mark the cable (so it can be seen by the operator) at a point that will give the operator sufficient time to stop the hoist prior to the last 2 wraps of hoist cable being spooled off the drum.
(2) Wind speed indicator. A device shall be provided to display the wind speed and shall be mounted above the upper rotating structure on tower cranes. On self-erecting cranes, it shall be mounted at or above the jib level. Temporary alternative measures: Use of wind speed information from a properly functioning indicating device on another tower crane on the same site, or a qualified person estimates the wind speed.
