Underestimated risk: Wind and crane operations

Liebherr delivers practical expertise on the subject of high wind speeds during crane operations.

Liebherr has 40 years of experience in the production of mobile cranes. We are committed to making crane operations safe and pass on our expertise to ensure this. One of our focal points in this respect is the clarification of risks and dangers caused by the effects of wind. Liebherr provides the requisite practical expertise for crane drivers and contractors in the form of professional training documents and courses.

Wind - identifying the risks

Wind can exert additional or reduced forces on a crane and can change character in a matter of seconds. It acts on both the load and the crane. Wind from the side exerts a massive additional load on the lateral stability of the crane. The wind load can often not be detected by the crane control.

In addition the form and weight of the load can also have a major impact for the effects of wind. For example, loads with large surface areas exposed to the wind, such as rotor blades, can exceed the parameters from standard load capacity tables.

Liebherr provides information about the effects of wind on crane operations and provides simple, readily understandable training on how to calculate the maximum permitted wind speeds in a given situation. This is the only way to make these crane jobs safe.

But one rule applies in every case: "Double the wind speed means four times the wind loading on the boom and load."
