This pump attachment to a skid-steer simplifies pouring concrete in difficult-to-reach locations. There’s no need for mud buggies, loaders with buckets, wheelbarrows, shovels, or chutes. Depending on hose length and diameter, and conditions such as slump, additives, and aggregate size and type, this attachment can pump concrete as far as 250 ft horizontally and up to two stories vertically. With a standard hydraulic flow loader, the pump can place concrete at up to 18 cu yds/hour. A high-flow loader can place concrete up to 28 cu yds/hour. Bobcat.
