ZM-20 is a special equipment specially designed and manufactured for underground non-coal mines to transport loose materials after blasting; It can also be used in railway, highway, water conservancy and other tunnel projects, especially suitable for poor working conditions, narrow, low and muddy working surfaces.
It has a strong climbing capacity and strong power, and can transfer itself within 5 km, saving freight costs for the user.
● The power system adopts today's advanced engine and is equipped with exhaust muffler purifier;
● The transmission system adopts hydraulic torque converter and power shift gearbox, which is easy to operate and stable;
● The working braking system adopts wet multi-disc braking, which increases the safety factor and is safe and reliable when working in harsh environment, high water content and muddy tunnels;
