Design:2 Vs Design:1
Start-up fee has reduced
Operated area is reduced
Number of Hydralic Lines has reduced
Advantagers of Fully Automated
Mechanical Rail-way Gate
No electricity needed
Low in maintain and easy in operation
Expensive in Start up
Hard to locate
Hard to repair when damaged
Thank You !!
