 A spring switchman Overview 
 1.SL-120 elastic switchman device (referred to as: switchman device) is a manual conversion switch equipment. 
 2 it to the spring tension to achieve the transition to be anti-position switch, and keep the function given the anti-position. 
 3 applies prone to "squeeze fork failure" in case of turnout, turnout will not damage the equipment once the squeeze. 
 4. It can lock the shaft penetration hole and the locking base with lock, lock the switch in fixed position against the state, in order to facilitate traffic through bifurcated safety. 
 Technical parameters of the spring switchman 
 1 ≤ 120 mm suitable opening switch 

 (2) applies to switch conversion resistance ≤ 1960N (200KG) 
 3 bar maximum linear displacement of 209 mm 

 4 Install two sleepers at 650 mm center distance, with the fork rod tip two sleepers centerline distance of 350 mm 

 5 double-track railway line in the middle of installation, the adjustable handles on both sides of the line from the center line should be ≥ 2250 mm 
 Scope: a railway line suitable for the use of sleeper board lots lining maintenance and repair operations work 
 With, road maintenance operations is to achieve mechanization to reduce labor intensity equipment.
