Push and pull rods are very important in the construction of railway signaling and track changing devices as each of them has a functional contribution in the mechanical activities of the signals and points (sw.). Such rods act as a linkage whose non-rotating end is attached to a motion actuator, such as a control and enables the operator of the system to reposition the trains as desired.
The following describes push pull rods including their importance in railways:
Overview of Push And Pull Rods:
Key Features of Push And Pull Rods:
Function:
Motion Transmission: Although many mechanical elements are involved in the showing of signs proved best. Push and pull rods are employed in delivering mechanical force perpendicularly from a lever or actuator to the sign or switch unit. Whereby a lever is pushed or pulled so are the rods as the signal is given or the direction of the track is taken.
Control of signals and switches: These rods assist the sign as well as the switch operator to operate them from a distance facilitating the effective running of trains on junctions and crossroads.
Material:
Durable Construction: Push and pull rods mostly consist of strong materials such as steel or aluminum making them suitable for construction since they can manage the mechanical exertions and hold up in severe environmental conditions.
Corrosion Resistance: Most rods are painted or coated to prevent corrosion of the metal to ensure subsistence of usage in active scenarios.
