Product Introduction
The ZL20EFB Underground Wheel Loader is a trackless transportation and loading machine for underground coal mines. Powered by a mine-specific explosion-proof diesel engine, it features hydrodynamic mechanical transmission and four-wheel drive. It is mainly used for loading, coal cleaning, slag cleaning and gangue discharging in underground coal mines with roadway gradients not exceeding 25%.
It boasts a compact structure, easy operation, small turning radius, strong heavy-duty climbing performance, low pollution and high efficiency. The machine can operate normally under the conditions of −20℃ to +40℃, relative humidity not exceeding 95% (at 25℃), and environments containing explosive gases and dust.
Product Features
●Adopts hydrodynamic mechanical transmission and power shifting, providing high traction force and breakout force.
●Equipped with dual-axle drive and wheel-side reduction.
●Uses articulated frame for easy alignment during loading and unloading, small turning radius and convenient maintenance.
●Applies air-hydraulic wet brakes with strong braking force, easy assembly and disassembly, and safe and reliable performance.
