HNYT has carried out a factory functional test of a ZQ-13 air loader, with workshop footage showing the rail-mounted machine lifting and lowering its bucket, slewing its upper body and moving along the test track. The test provides a closer look at the movements used in underground rock loading, where the loader gathers broken material at the working face and transfers it to the mine haulage system.

The video follows one yellow loader operated from the side controls, with a second member of the factory team nearby. Its black bucket, lifting frame, pneumatic connections and rail wheels remain visible through the sequence, allowing buyers to see how the assembled machine responds during operation.

Bucket and slewing movements on the test track

During the test, the operator repeatedly raises the bucket from its low forward position through the lifting arc and returns it toward the rails. The changing bucket positions reveal the movement of the lifting assembly and the space occupied above the machine during a cycle. This is a useful view for engineers assessing how the loading mechanism will fit within a mine roadway.

The footage also shows the upper body turning to either side while the wheeled chassis remains aligned with the rails. The bucket is repositioned across the front of the machine and brought back toward the track centreline. In a working heading, this movement helps the operator approach material across the loading area without changing the direction of the track.

Short movements along the rails form another part of the sequence. Seen together, the travel, bucket and slewing actions show the principal motions that must work together when the loader is positioned at the face. The visible cycles use an empty bucket; they demonstrate functional movement rather than a measured rock-loading output.

A compact pneumatic loader for rail-based mucking

Сайт ZQ-13 air rock loader uses compressed air and a single bucket for loading broken rock or ore. HNYT’s published model data lists a bucket volume of 0.13 m³, a working-air pressure range of 0.45–0.86 MPa and rail-gauge options of 600, 762 and 900 mm. These are model reference values; the gauge and air pressure used in this particular test are not identified in the footage.

The product page gives a tunnel width and height reference of 1.7 × 1.9 m and an unloading height of 1,250 mm. For an actual installation, those figures need to be considered alongside the full bucket movement, operator space and receiving-car dimensions. A machine that fits on the rails must also have enough room to complete its loading cycle.

Connecting the factory demonstration with mine requirements

For a mine evaluating this rock loading machine, the workshop demonstration makes the operating arrangement easier to assess: the operator works beside the loader, the bucket moves through an overhead arc, and the chassis follows the railway. These details influence roadway clearance, track layout and the position of the receiving equipment at the working face.

Compressed-air availability is another part of that assessment. Buyers should provide both the pressure and flow available at the loader, together with the air-line arrangement, so the supply can be reviewed for the intended duty. Tunnel dimensions, track gauge, material size and required output should be considered together, as outlined in HNYT’s rock loader application and selection guide.

The factory test adds an operating view to the model’s published specifications. Buyers looking for a separate delivery reference can also read about HNYT’s shipment of six ZQ-13 rock loaders for metal mining in Africa.
