5. trolley reversion is to horn afterbody (as Figure 14 C), and hanger rail shoulder pole declines, and track switch falls within on main frame guide rail loopback automatic mechanism (as Figure 14 D).

6. subsidiary engine and main frame contraposition, starts guide rail loopback automatic mechanism, and track switch is transmitted back on subsidiary engine guide rail loopback automatic mechanism (as Figure 14 E).

7. subsidiary engine transports track switch to the frame that changes the outfit (as Figure 14 F), the frame that the changes the outfit track switch (as Figure 14 G) of slinging, and subsidiary engine exits the frame that changes the outfit (as Figure 14 H).

8. locomotive pushes flatcar and enters the frame that changes the outfit, and track switch falls within on flatcar, and locomotive traction flatcar rolls the frame that changes the outfit away from.

9. main frame is packed up hydraulic leg, retreats contraposition.Repeat 1-8, until ABC tri-part track switches are reclaimed complete.

The step of lay-up operation is as follows:

10. main frame contraposition, a upper hydraulic leg, main frame is positioned at the paving state for the treatment of (as Figure 15 A).

11. locomotives push the flatcar that new track switch is housed and enter the frame that changes the outfit, the frame that the changes the outfit track switch of slinging, and locomotive traction flatcar rolls the frame that changes the outfit away from.

12. subsidiary engines enter the frame that changes the outfit (as Figure 15 B), the frame whereabouts track switch (as Figure 15 C) on subsidiary engine that changes the outfit, subsidiary engine transport track switch and main frame contraposition (as Figure 15 D).

13. start main frame traction system, and track switch enters main frame, and subsidiary engine returns to (as Figure 15 E).

14. trolleys are at horn afterbody, and hanger rail shoulder pole declines, and press 3600mm spacing and lock track switch, and lift by crane track switch (as Figure 15 F) with the soft rope of nylon.

15. trolleys move ahead, hanger rail shoulder pole decline (as Figure 15 G).By front and back oscillating arm mechanisms, adjust horn position, track switch contraposition.Track switch is laid complete, and hanger rail shoulder pole rises, and by front and back oscillating arm mechanisms, adjusts horn return centering (as Figure 15 H), and trolley reversion is to horn afterbody.

16. main frames are packed up hydraulic leg, move ahead, and contraposition, a upper hydraulic leg, main frame is positioned at the paving state for the treatment of.Repeat 11-15, until ABC tri-part track switches are laid complete.
