Operating Cranes in Stormy Weather
It takes a skilled operator to handle a crane and inclement weather can make it even more dangerous, so it’s important that you choose reputable crane contractors who are experienced in operating cranes in bad weather. The weather isn’t something we can wait around for to get a job done, and weather delays can cost not only time, but also money. Regardless of the weather, each job must push on and this means that sometimes cranes and equipment may have to be operated in stormy or bad conditions. In order to do this, a number of precautionary measures should be followed to minimise risk.
We’re used to a bit of wind up north, so understanding how to safely use cranes in these conditions is paramount. Each crane has a designated maximum wind speed under which they can be safely operated. If the winds are higher than this, the crane cannot be operated safely. Different models and configurations have their own wind ratings so check the designated speeds for yours. The absolute maximum wind speeds that a crane should operate in are 20 miles an hour, and if it goes above 15 miles per hour, consider a delay if at all possible.
If you are operating a crane in high winds, it also depends on your load. The load can affect your safety if the wind catches is. Also check the direction the wind is blowing as side or rear winds can make the load swing and damage the crane.
The higher you go, the more wind speed increases so your crane might be more susceptible to high winds depending on its height. Also be aware of the wind tunnel effect if you are operating the crane between two structures.
Extremely low temperatures can have a negative impact on crane performance too – it can affect the tensile strength of the crane and could cause a disastrous failure during operation. At around 0 degrees C, the hoists and rigging devices can be affected. Below that there could be issues with the hydraulics and the load capacity can be altered by as much as 25%.
Cold weather adjustments
If you need to operate a crane in the cold, then you can make some adjustments to decrease the risks. Cold weather finishes such as hold-dipped galvanised steel are available and can operates in temperatures as low as minus 57. Enclosed track systems, can protect the crane’s trolley from a build up of ice that happens in lower temperatures.
Electrified systems can aid the operation of motorised systems. Conductor bar sections serve as a cold weather alternative to box track festooning. They are made from galvanised steel and are designed to carry a specific current without overheating. They also prevent the build-up of ice and other debris on the crane’s joints. Other crane parts are available specifically for cold weather such as artic duty motors, heated control gearboxes and enclosures.
