APG unit

The car exchange units in the APG stands are intended for mechanization of the swap process of single car in single- and multistory stands of two- and one-stand lifts.

The units are used at the reception sites of the shaft insets of the final and intermediate horizons of mines, hazardous due to high levels of gas and dust accumulation, with any humidity levels and water abundance in the schemes of the forced car swap.

The units provide for the swap of cars of VG, VD and VDK types with a capacity of up to 3.3 M³ with hook and automatic couplings with rigid and cable reinforcement in the stands with lateral or frontal arrangement of conductors.

To ensure the normal operation of the units, the air pressure in the mine network must be 0.4-0.6 MPa (4-6 kgf / cm²).

The units can beallocated with an interpath distance of at least 1520 mm for a track of 600 mm and 1770 mm for a track of 900 mm in accordance with the approved technological schemes for the exchange and car haulage .

The cars are delivered to the unit by a cable pusher (or other mechanisms) with a speed of no more than 0.5 m / s.

Devices providing the feedingof the cars to the unit’s stopper at a speed of no more than 0.5 m / s.must be provided when installing the APG units in existing mines that have a scooter slope.

The operator controls the unit from the control panel installed in the stable hole with the operator providing a sufficient overview of the receiving area.

The work of the units is provided for at the receiving sites with one-way trolley traffic and is impossible in dead-end yielding.
