When working near a cellar wall, the crane's outrigger pads or tracks should be placed how far back?

When working near a cellar wall, the proper placement of the crane's outrigger pads or tracks is crucial for safety and stability. The correct guideline is to position the outrigger pads or tracks at least as far back as the depth of the wall below ground. This practice ensures that the crane’s weight is adequately distributed and minimizes the risk of destabilization or collapse due to the weight of the equipment and load being handled.

By maintaining this distance, the forces exerted by the crane do not compromise the integrity of the cellar wall or surrounding soil. If the crane were positioned too close to the edge, there could be a risk of soil erosion or failure, which could lead to accidents or equipment damage. The depth of the cellar wall below ground is a critical factor since it contributes to how much earth is supporting the wall and the crane itself. Therefore, adhering to this guideline significantly enhances safety protocols when operating cranes in proximity to various structures.
