Portec Rail MACK™ Reversible Switch Point Protectors
Wheel flanges impact very heavy loads against the toe of a switch point. This results in rapid deterioration of the switch point and eventually leads to chipping of the running edge. Portec Rail MACK™ Switch Point Protectors take the brunt of this impact and divert the wheel flanges from the point. MACK™ Protectors are made from high quality manganese steel and are reversible when one edge becomes worn. Their use prolongs the life of a switch point by as much as five times. In addition to reducing wear on switch points, MACK™ Protectors help to prevent derailments due to split switches by helping deflect wheel flanges past any switch that is not completely closed. MACK™ Reversible Switch Point Protectors are designed for slow speed territory and are ideally suited to yards, industrial loads and private sidings. A maximum speed of 15 mph (25 kph) is advised.
