The HGY-19/2 concrete spreading machine is a spreading equipment used in conjunction with concrete pumps for concrete pouring operations during construction. The use of concrete fabric can fully utilize the working efficiency of concrete pumps, improve pouring quality, and reduce labor intensity.The HGY-19/2 concrete laying machine consists of a laying arm assembly, a rotating support, a tower body, a chassis, concrete pipelines, a hydraulic system, and an electrical control system. The fabric arm is a two section box structure, and the horizontal rotation of the two arm sections is achieved through a hydraulic system, which can transport concrete to the required construction surface. The hydraulic system is equipped with a safety relief valve to prevent overloading of the working mechanism.The electrical control system can achieve control cabinet panel operation and wired remote control operation. There is an interlock function between different operation modes to ensure safe use.This equipment needs to be installed with the help of a crane. Before installation, it should be confirmed whether the lifting performance of the crane meets the requirements.
