Haomei HBT series concrete pumps are concrete pumping machines, including S-valve series of high-pressure concrete pumps, Z-gate-valve series of medium-pressure concrete pumps and D-butterfly-valve series of low-pressure concrete pumps. Features of trailer concrete pump use S-valve to switch the direction, for fine stone concrete conveying good sealing S-valve, installed with floating wear resistant ring High-quality wear resistant alloy components for long service-life high delivery pressure for demand of high-rise and long distance projects double-loop open circuit hydraulic system, ensure fast direction switching speed and high efficiency air cooling system, without dependence of external water supply with re-pumping function to smooth construction of better accessibility automatic lubrication system for long service-life PLC system to ensure best electrical control performance equipped with wired remote controller, easy to operate Application of trailer Concrete Pump The trailer concrete pumps are based on technical pioneer achievements. They keep researching and developing new technology - and have been doing so for many years!They are the national initiative equipment for fine stone concrete conveying and won two national patents. ·Fine stone concrete conveying ·Floor heating construction ·Tunnel and underground construction ·Mortar conveying ·Used as spray pump when Installed with incidental spraying equipment, for concrete, mortar, refractory material and green soil spraying ·Trailer concrete pumps are applied for high-rise conveying, railway, tunnel, bridge construction and special applications, hydraulic power, mining and national defense.
