The KPO clamp rail fastening system is a commonly used solution for securing railway tracks. It consists of KPO clamps, iron pads, and bolts that connect the rails to the sleepers. The KPO system employs a rigid connection ensuring that the rails remain firmly fixed in place and preventing track loosening or movement. Its effectiveness in supporting heavy loads and its durability under harsh conditions make it a preferred choice for heavy railways, port transportation, and mining tracks.
