HBT6006A-5 Trailer-Mounted Concrete Pump adopts pressure difference induction commutation technology and is equipped with electro-hydraulic proportional buffer technology. It not only has the advantages of the open system’s self-circulating filtering of impurities, high hydraulic oil cleanliness and low temperature, but also has the characteristics of small reversing impact of the closed system, which maximizes the system efficiency, reduces the wear between parts, and prolongs the life of the system. Extended service life and reduced maintenance costs.
