The KTCJ-4 mining‑safety model concrete mixer has an actual capacity of 4.4 m³ and is suitable for transporting concrete in underground mines and tunnels with a clearance height of 2.4 meters or greater. It features powerful liquid cooling, a high‑output turbocharged engine delivering 119 kW, and a maximum speed of 9 km/h when fully loaded on a 1:7 uphill tunnel grade. On level tunnels, its top speed reaches 25 km/h. Standard drum‑elevator specifications allow flexible adjustment of the concrete discharge height up to 1.9 meters, enabling unloading even when the receiving unit is positioned at an angle or offset relative to the concrete transporter.

The RV‑16 trackless water‑spraying vehicle, designed for mining safety, is primarily used for underground dust suppression and features a professionally engineered chassis. Powered by a diesel engine, it offers excellent adaptability. The vehicle boasts high crashworthiness, low fuel consumption, reduced overall operating costs, simple operation, comfortable ride quality, a well‑thought‑out structure, and easy maintenance and servicing. Key electrical components—including the controller—as well as critical parts of the hydraulic and transmission systems are sourced from renowned domestic and international brands, ensuring reliable performance. Its braking system employs wet brakes with spring‑applied, hydraulically released actuators, further enhancing safety. The cab is fully sealed and equipped with air conditioning, while the water‑spraying function helps reduce airborne dust and other harmful substances, creating a healthier working environment for miners. Additionally, the vehicle is suitable for operation in extremely cold conditions.
