The Bobcat concrete pump attachment is designed for working in confined spaces. According to Bobcat, either side of the pump can be attached to the loader for best positioning. Depending on delivery-hose length and diameter, slump of the concrete, aggregate size and additives used, the pump attachment can move concrete as far as 250 feet horizontally, or up to two stories vertically. If driven by a loader with a high-flow auxiliary hydraulic system, the pump can deliver up to 28 cubic yards per hour.
