What device shall be provided for outdoor stored bridge cranes?

The requirement for wind indicators for outdoor stored bridge cranes is crucial for ensuring safety and operational efficiency. These devices provide critical information about wind speed and direction, which are essential factors when operating cranes. In outdoor settings, bridge cranes are particularly vulnerable to wind gusts that can affect their stability and the loads being lifted.

Wind indicators help operators assess the operational limits of the crane, allowing them to make informed decisions about whether it is safe to lift or move loads in windy conditions. By monitoring wind conditions, operators can prevent potential accidents and equipment failure that might occur due to strong winds.

In contrast, while temperature gauges, rain shields, and sun shades may provide some benefits to the operation and condition of the crane, they do not directly address the risk of wind. Temperature gauges are more relevant for monitoring environmental conditions that could affect machinery performance, rain shields protect against water damage, and sun shades help reduce heat build-up. However, none of these devices specifically mitigate the risks posed by wind during crane operations, making wind indicators the necessary device for ensuring safety in outdoor environments.
