One of the rigger’s most important tasks is determining weight for civil rigging, specifically the weight of the load. This is the first critical step in planning a successful and safe lift.
Do you know the three basic ways that riggers determine weight?
According to Ralf Notheis, Manager of Bigfoot Crane Academy, only the third way requires math skills. “Sometimes the weight of loads is already supplied to the rigger,” says Notheis, “either marked on the load itself or in the paperwork, such as blueprints, spec sheets, or manuals.”
However, every rigger must have the skill to measure a load by simple math, whether in cubic feet (Ft3), square feet (Ft2), or linear feet (Lf).
Of course, different materials, such as concrete, steel, or wood, are weighted differently and must be calculated accordingly.
Calculating the weight of unique objects such as concrete pipes provides a unique challenge, which emphasizes that the well trained rigger must be fluent in the necessary equations.
As with all civil rigging training, the emphasis is on being practical and staying safe. Everything a rigger needs to learn about determining weight is provided in a way that makes sense on the job. The trainers help to create a good environment for learning so that the rigger can grow in confidence and be ready for the challenges of their work.
