Product Description

GP-20JT Integrated Shotcrete machine/Concrete spray machine/Sprayer machine/Shotcrete gunning machine//Wet spray shotcrete for tunnelling support
Product introduction 
GP-20JT engineering concrete wet spraying jumbo is an upgrade of the product to adapt to the current tunnel construction. It is a electro-hydraulic integrated concrete spraying equipment which has absorbed the advantages of domestic and foreign famous brand products in design and manufacturing. The performance parameters have reached and exceeded the level of similar international products. It adopted heavy-duty articulated chassis design, reasonable structure layout, flexible. Meanwhile, with build-in 45kw air compressor, which make the operation much easier with higher efficiency. 
The key parts of the engineering concrete wet spraying jumbo, such as the robotic arm, pumping system, hydraulic system, electrical system, etc., adopt international and domestic well-known brand products. The electrical system has PROFINET technology, and the engineering machinery controller based on the embedded system is the core. It is a real-time, effective, and flexible new control system that realizes the integration of electromechanical and hydraulic control. It is fully responsible for the engine, hydraulic pump, hydraulic control valve and the composite control of the whole machine detects and protects the engine, hydraulic system and working state in real time, thus ensuring the high reliability and high stability of the whole machine.
GP-20JT engineering concrete wet-spray jumbo has excellent structure, firmness and strong impact resistance. There are no blind spots in the construction of the working arm; the advantages of high construction efficiency fully reflect the company's tenet of "make construction easier".
