Abstract

A bucket loader apparatus for scooping, filling, transporting and placing a plurality of bags used in constructing barriers. The bucket loader includes a universal mounting attachment for attachment to a loading vehicle whereby the loading vehicle manipulates the bucket loader between a range of dispositions. In a scooping disposition, the loading vehicle directs the bucket loader to scoop a flowable, granular material. In a loading disposition, the flowable granular material is directed through a plurality of integral funnels and into a plurality of bags, each funnel having a bag retained proximally to the funnel. After filling the bags, the bucket loader is transported to a point of use whereby the loading vehicle manipulates the loader bucket to an unloading disposition allowing placement of the filled bags. The bucket loader further includes a bag attachment assembly for selectively retaining empty bags and releasing filled bags.
