ASME B30.27 Pump Truck Safety Protocol:

Up to 80% to 90% of the entire truck weight plus the full concrete column in the delivery pipe can be transferred onto a single front outrigger during horizontal boom extension. Operating without adequate timber dunnage cribbing on soft soils causes punch-through ground failure, leading to catastrophic equipment turnover.
