(c) A wind-indicating device shall be provided. The device shall give a visible and audible alarm at a predetermined wind velocity discernible In the operator’s cab and at the ground level.
(d) Cranes shall be prevented from tipping when subjected to nonoperating wind conditions. The overturning moment shall not exceed 80% of the stabilizing or resisting moment, When the crane is stowed, external restraints may be used to achieve the required resisting moment.
(e) The crane manufacturer shall provide data indicating the design maximum operating wind velocities and the wind velocity at which the use of external restraints 01 the crane is required.
(f) Operating instructions for high wind conditions shall be provided in the operators cab. The instructions shall include procedures for responding to high wind alerts.
24-1,4.2 WeLded Construction
Welding procedures and welding operator qualil’lcations to be used on load-sustaining members shall be in accordance with ANSI/AWS D1.1, except as modified by ANSI/AWS 1)14.1. Where special steels are used, the manufacturer or qualified person shall provide welding procedures.
24-1.4.3 Crane StructuraL Members
Cranes shall be constructed to withstand all stresses imposed on members and components under normal operating conditions when installed and handling loads not exceeding the manufacturer’s load ratings.
24-1.4.4 Truck Frame Drop
Means shall be provided to limit the drop of a rail- mounted crane’s trolley and gantry truck frames to a maximum of 1 in, (25.4 mm) In case of wheel or axle breakage.

The gantry drive shall provide adequate traction and power under normal operating conditions to include acceleration and deceleration with and against the specified operating wind.
24-1.4.7 Spreader
(a) The spreader shall be constructed so that the twist- locks will engage the corner castings o interinodal ship. ping containers.
(b) The control of the spreader shall be from the opera. tor’s cab.
(c) A mechanical, hydraulic, and/or electrical Inter. locking system(s) shall be provided to prevent unlocking the twist-locks when carrying a container and to prevent locking action oIthc twist-lock system until all twlst•locks are seated In the corner castings.
(d) A means shall be provided to enable the operator to determine that the container corner castings have been properly engaged.
24-1.4.8 ELectromagnetic Interference
For cranes operating in areas susceptible to electromagnetic interference (F.Ml), crane electrical systems shall be shielded and grounded to protect from EMI.
24-1.4.9 Guards for Moving Parts
Exposed moving parts, such as gears, set screws, projecting keys, chains, and chain sprockets, that constitute a hazard, shall be guarded with guards meeting the requirements of ASME K15J.
