The machine loading PPN-3A pneumatic direct loading, is intended for loading of the blown-up mountain mass of any fortress and abrasivity in trolleys, on the conveyor or other trasport facilities when passing lateral mine workings on the developed underground mineral deposits and construction of underground structures.
The machine makes loading of mountain weight with fineness of pieces to 600 mm in developments not less than 2,85 m high from a rail head. Loading is made from a railway line on which the machine moves.
The machine consists of the following main nodes - the mechanism of movement, a rotary platform, the mechanism of rise, an operating part, the control panel, the swinging mechanism and an irrigation system.
Loader of PPN3A of batch action with the lower capture of mountain weight, direct loading, with the wheel and rail mechanism of movement, rope stabilization of an operating part and the pneumatic drive.
The machine is quite simple in design, convenient in management and service, is productive and reliable in work. For decrease in fatigue of the operator the machine is equipped with the muffler of noise and an anti-vibration footboard.
