Car loading PPN-1S
pneumatic direct loading, it is intended for loading of the blown-up mountain mass of any fortress and abrasivity in trolleys, on the conveyor or other vehicles at a driving of horizontal excavations on the developed underground mineral deposits and construction of underground constructions.
The car can load mountain weight with fineness of pieces to 400 mm in developments not less than 2,3 m high from a rail head. Loading is made from a railway line on which the car moves.
Developments have to be equipped with railway lines with the track of 600, 750 or 900 mm, highways which are carrying out compressed air with a pressure of 0,5 MPas and water for dust suppression with a pressure of 0,4-1,6 MPas. Air temperature at operation of the car has to be from +5 to +35 °C.
The main knots are: a running gear, a rotary platform, a rise reducer, working body, the case with the control panel installed on it, the mechanism of turn and an irrigation system. The car is put in action by two 9 kW pneumomotors everyone.
The loader of PPN-1S is simple on a design, is convenient in management and service, is reliable in work.
