When severe weather conditions come into play, the risks and challenges of operating mobile cranes multiply, making it crucial for operators and site managers to be well-prepared. Here we explore the various impacts of severe weather on mobile crane operations and discuss training options and safety precautions that you and your team can take advantage of during inclement weather.
One of the most significant threats to mobile crane operations is high winds. As many of you know, cranes are particularly vulnerable to wind due to their height and the nature of their loads. High winds can cause instability and even tipping, posing serious risks to both the crane operator and ground personnel. Additionally, strong winds make it challenging to control loads, increasing the likelihood of accidents. Below you can see a training scenario taking place in the ITI VR Crane Simulator, which features varying wind conditions, designed to challenge operators.
To mitigate these risks, it's essential to adhere to manufacturer guidelines on maximum safe wind speeds. Operations are typically halted if wind speeds exceed certain thresholds. Regular wind speed monitoring and having a clear wind action plan are vital components of safe crane operation.
Heavy rain can severely impact mobile crane operations by reducing visibility for the operator. Poor visibility makes it difficult to perform precise maneuvers, increasing the risk of collisions and accidents. Furthermore, rain can create slippery surfaces, compromising the stability of the crane and endangering ground personnel.
In rainy conditions, it's important to ensure that all surfaces are as dry and secure as possible. Using anti-slip materials and ensuring proper drainage can help mitigate some of these risks.
Cranes can essentially act as lightning rods during thunderstorms, presenting a severe risk of electrical shock. It is crucial to stop crane operations and ground the crane properly when there is a threat of lightning. Implementing a lightning safety plan and monitoring weather forecasts can help prevent accidents.
Snow and Ice - Added Weight and Mechanical Issues
Regularly removing snow and ice from the crane and its components, as well as performing frequent mechanical checks, are essential practices in cold weather.
Ensuring that the ground is stable and secure before operating the crane in flood-prone areas is crucial. Planning alternative routes and having contingency plans for site accessibility is always wise as it can help maintain operational efficiency during floods.
When in doubt, it's always a good idea to consider the following precautions:
