Learn about 3 factors that affect the maximum reach of a mobile crane.

4 Potentially Hazardous Weather Conditions

Some projects need to continue even if the weather conditions are less than ideal. While work can still be performed in most situations, it is important to take several precautions in the following weather conditions:

1. High-Speed Winds

Most mobile crane manufacturers include the maximum wind speed for safe operation in their technical manuals, so it is important to keep this information in mind during operation. The most important factors to consider when dealing with wind are the size and weight of the materials and how high they need to be lifted. Wind speeds increase with height, so it is important to ensure that your crane has an anemometer fitted on the jib. If the speeds are too high, it is best to wait until the wind settles down before performing the lift.

2. Heavy Rain or Snow

Heavy rain or snow can drastically reduce visibility, making most lifts more prone to safety risks. Rain and snow can also reduce traction for mobile cranes, affecting total lift capacity and maneuverability unless the unit is outfitted with tracks. Rain or snow are often the most subjective weather conditions, as every operator will have a varying level of comfort. Should rain or snow ever cause doubts for a lift, it is always best to wait until weather conditions improve.

3. Extreme Heat

Summer heat can greatly increase strain on mobile crane fluids, moving components, and the operator. A close inspection of all fluid levels and the condition of seals is crucial before each lift, as heat can cause expansion or leaks. If the operator is not adequately prepared for the heat, they may become queasy or lightheaded. If this occurs, operations should be halted immediately until the operator recovers.

4. Thunder and Lightning

If thunder or lightning are present, operations should cease immediately until the storm has passed. A crane can act as a lightning rod during a storm, posing a major risk to the operator and all nearby personnel. A lightning strike can also cause immense damage to equipment, potentially even rendering it inoperable.
