HB41 adopts Hino FSIERV (6X4) three-axle chassis, excellent power performance and good economics. Front X type outrigger could operate on one side, and open semi-outrigger in narrow area. 5-section RZ type folded boom needs small space for boom folding and unfolding. The main vehicle pumping adopts opened delivery technology, fully hydraulic reversing technology, intelligent pumping damping technology, small pumping reversing impact. The concrete piston could withdraw automatically. The application of the engine energy saving technology and trouble-shooting technology improves the economics, reliability and safety of the concrete pump.
