Fixed mine car Simple structure, rugged durable, low resistance coefficient, large load capacity, easy maintenance.Unloading: use tippler to flip entire car body.

Widely used: coal mining, non metallic mineral development, bulk material transport in construction, gangue large scale transport, metal/non metal ore/waste transfer.

Tunnel projects: railway/highway/water tunnel construction, muck removal, lining material supply.

Civil works: concrete aggregate for bridges/railways.  

Port yards: bulk cargo loading/unloading, yard circulation.

Structural Features & Working Principle:

Integral box structure: High strength steel plate welding. Strong box seal. Prevent material spillage. Adapt complex coal mine underground conditions.

Reinforced chassis: Channel steel + heavy rail welded chassis. Mine car specific wheel sets. Buffer coupling devices. Ensure stable reliable operation.

Modular design: Standardized key parts. Quick disassembly/replacement. Easy maintenance. Reduce downtime.

Impact resistant design: Thickened steel plates + stiffeners at key stress points. Stress relieved structure. High deformation resistance.

Universal interface: Standard traction chain rings + pin coupling system. Flexible train formation. Compatible with common traction equipment.

Working principle: Fixed box mine cars form trains via traction equipment. Load material at loading point. Hauled to discharge point by locomotive/winch. Discharge: Train/single car enters tippler station. Tippler rotates car body (160°~180°). Material slides down box slope under gravity. Tippler resets to horizontal. Car returns to loading point for cycle. No manual unloading. High mechanization. Suitable for continuous, large scale bulk material transport systems.
