Product Introduction
The KPO fastener system is a clamping fastening solution for railway tracks, covering three series: KPO3, KPO6, and KPO9. The system consists of KPO clips, threaded spikes, hexagonal bolt and nut sets, conical spring washers, and elastic pads under the rail. The clips are cold-formed with Q235 steel, and the spikes and other load-bearing parts are made of 45# medium carbon steel.
It is mainly used for track laying in urban rail transit, and can absorb the vibration energy during train operation. Its advantages are fast installation and compact structure. The production process includes steel cold processing, mechanical tapping, surface anti-rust coating and other processes.
KPO3, KPO6, and KPO9 are different models of buckle plates in the KPO type railway fastener system, which are widely used on crane tracks.
Applicable scenarios
KPO3: Generally suitable for some light crane tracks, such as small bridge cranes and electric hoists in workshops. These cranes have relatively small lifting weights and slow running speeds, and the load requirements for track fasteners are not particularly high.
KPO6: Commonly used for crane tracks with moderate lifting weights, such as bridge crane tracks in some medium-sized factories and portal crane tracks in ports. It can meet the requirements of frequent operation and operation of cranes under medium load conditions.
KPO9: Mainly used for heavy-duty crane tracks, such as casting crane tracks in large steel plants and large loading and unloading bridge tracks in mines. The cranes in these places have large lifting weights and frequent operations, and the tracks need to withstand huge loads and impact forces. KPO9, with its strong buckling pressure and stability, can ensure the safe operation of the tracks under long-term heavy loads.
