What is the purpose of placing mats or cribbing under outrigger floats?

The purpose of placing mats or cribbing under outrigger floats is to distribute the downward force of the float over a larger area. When a crane operates, particularly during lifting operations, significant loads are transferred to the outriggers, which need to support the weight of the crane and the load being lifted. Mats or cribbing help mitigate the risk of soil displacement and ground failure by spreading out the support surface area, ensuring greater stability. This is particularly important in areas with softer ground or uneven surfaces, where concentrated pressure from the outriggers could lead to sinking or tipping. By using these materials, the overall stability of the crane is enhanced, which is crucial for safe operation.
