LPS-DSC-400 is a dry and wet concrete pumping and spraying machine coating applications with reduced operating and owning costs. This machine can easily handle all popular types of shotcrete concretes containing different sizes and shapes of aggregates, gravels, crushed gravels and pebbles up to 20 mm sizes with its unique rotor structure. lmproved rotor geometry, high quality steel and rubber plates reduce operating costs due to electricity and air consumption. Automatic rotor lubricating system increases rubber and steel plates’ operating life. Water-proof electrical control cabinet design prevents leakage current and provides operator safety. Phase sequence protection over and under voltage protection over current protection. thermal protection are seme of electrical safety features. AII electrical parts used for electrical system, cables breakers, buttons, relays, ete are made by SIEMENS. Simple and service-friendly con-sumables reduce maintenance costs and time loss. No need to have a qualified maintenance personal for chan-ging consumable spare parts. After maintenance no need for any calibration or adjustment. With its compact design and sma dimensions allow operators to work through nar-row tunnels and in low ceilinged places.
