Cranes in Winter
Once the first snow falls, work on the construction site gradually comes to a halt. Construction machinery is rarely or seldom operated and becomes covered by frost and snow. Nevertheless, a few precautions must be taken on the construction site as soon as winter approaches. There are also essential things to consider when operating a crane as the temperature approaches freezing.
What you can do to winterize your crane and when you should shut down your construction site, we explain below.
Cranes in Winter – What to Consider Before Operation
Machines on the construction site can not only suffer damage in sub-zero temperatures and heavy snow, they can also become a hazard. Therefore, you should be aware that snow can accumulate on the wire rope pulleys in winter. The rope can not only slip out of place, but in the worst case even break – all employees should be aware of this.
1. Check the Brakes
The brakes on the crane can freeze overnight and are therefore no longer functional. Be sure to check this and absolutely perform a operational inspection every morning!
2. Water Can Enter the Crane Gearbox
Be aware that the gearbox and other components warm up once you use the crane. If there is a large layer of snow on the crane, it will melt. The consequence: water that can cause damage to the motors, plug connections or control cabinets.
3. Snow on the Boom
If there is a large amount of snow on the boom, first attach a light load and let the trolley run across the entire boom – the weight ensures that the snow on the boom is removed. If necessary, repeat this until the boom is largely cleared of snow.

Cranes in Winter – Taking Equipment Out of Service
There are also a few things to keep in mind when taking equipment out of service. With the following tips, you can avoid freezing or damage to your crane:
- Make sure you do not park the trolley and hook block in the limit switch – this can cause problems when the crane is put back into operation, as the trolley and hook block can freeze.
- Close the cabin window and keep the cabin heating at a reduced level.
- Do not leave items such as radio remote controls, batteries, etc. in the cabin, but store them in a dry location.
Snow on Construction Sites – Why It Becomes a Hazard
For earthwork and concrete work, the temperature limit is minus five degrees Celsius. Beyond this point, it becomes difficult for both people and machines to work. Additional energy sources would also require more budget. Therefore: Snow on construction sites must, if necessary, be properly cleared and salt must be spread so that work can safely resume. Important elements on the construction site may be covered by snow and thus become a tripping hazard. If there is a risk of slipping, the construction site is no longer safe for people and machines to access, so appropriate work clothing, such as slip-resistant shoes, must be used. Slush can also become a hazard: falling icicles from cranes or snow buildup can strike employees, and water can enter motors and cause crane damage.
