the circuits of the block sections 4, 5,6 of the floor-rail machine include the contact 46 of the blocking relay of the fourth block section of the crane circuit (not shown), contacts 47 and

48 blocking relay of the n block. five

Relays 49, 50 are connected to the common wire 32 and the trolley by shunting the cranes rail circuits by contacts 51 and 52 connected to the edge-i mechanism of the mechanism for moving the edge-i through the pin location mechanism of the pin mechanism 53, 54 To common wire 33 and,. Trolley connected bypass relay 55, 56. rail circuits of the floor-rail vehicle, with contacts 57 and 58, included in the circuit 15, Schanism starters of the movement of the floor rail machine and in the circuit of the preventive 5T1

The device is powered from the source 59 pg. Yug. The device operates as follows. With free block sections 1-6, 7 to 15 reed relays are turned on. Their nbrSchSCHBT-closed contacts 16-25 rail chains, closed. The track circuits of the block sections 25 1-6 are supplied with voltage of both polarities from the power source 59. If the pin mechanism is located to the right of the block section 2, then the track; the switch 53. is closed, and the voltage of the safe polarity is applied to the winding of the relay 49 Shun yTroTvany, and the relay 49 is turned on. Since the current running of the relay 49 is significantly greater than the lowering current of the blocking relay 9, then at the termination of the resistor 35, a voltage drop will occur, the relay 9 will be de-energized and will open its normally open econte: sections 4 and 6

rail chains of the right-track iviaiflHHbi of the right row: There will be no voltage applied to the sectional trolls of this machine, therefore at 40

In the masking area of these blocks, it will stop in connection with the fact that the pin mechanism is on the right side, the track switch 54 will not be closed. If the block section 2 is occupied by a crane, the shunting relay 50 will not turn on and the blocking relay 10 will not be de-energized. The sectional trolley of the left-hand floor-rail machine (not shown in the drawing) will be energized, so the machine of this row can freely move. : If the right hand machine is located in the block section 2, then the contacts 23, 24 of the blocking relay 14 in the track circuits of the crane block 1 and 3 are open, the sections 1 and 2 of the sectioning troll of the crane are de-energized. In this case, if the pin mechanism of the crane is on the right, then at the entrance of the crane to the block 3 bypass relay 49, the crane is de-energized and the crane remains open, since in the chain of the crane movement actuator the contact 51 is open.
