Product Introduction
KPO fastener system belongs to the clip-type fastening system, which is mainly classified into KPO3, KPO6, KPO9, etc. Its components include KPO clips, screw spikes, sleeper pins, bolts, nuts, washers, and rail pads. Clips are usually made of Q235 material, and other metal parts such as screw spikes are made of Q235, 35#, 45# and other materials according to different grades. This system is mainly used for fixing railway tracks, especially crane tracks. The advantage is that it has stronger clamping force and longer service life than ordinary fastening systems. The production process covers forging and machining of metal parts, as well as surface treatment such as galvanizing to improve the corrosion resistance of the parts.
KPO rail fastener system is a fastener system commonly used in crane rails. It is a rigid fastener with simple structure, easy installation and good stability.
The gusset plate is fastened to the rail and sleeper by bolts, and the rail is fixed to the sleeper by the buckling pressure of the gusset plate, so as to achieve the connection and fixation between the rail and the sleeper. The gauge block can adjust the position of the rail to ensure the accuracy of the gauge. The insulating gasket can prevent the electrical connection between the rail and the sleeper and reduce the influence of stray current.

Product Packaging & Delivery
Hard plastic compartment box + corrugated outer box nested packaging: For scattered small fasteners, hard plastic compartment boxes are used for primary packaging. Each compartment box has an independent transparent box cover, and soft silicone pads are laid inside the box to prevent scratches. The compartment boxes filled with fasteners of different specifications are neatly placed in a customized double-layer corrugated outer box. The card slots are set inside the outer box to ensure that the compartment boxes are fixed and do not shake. After the top of the outer box is covered, it is sealed with environmentally friendly paper tape and then cross-bound with fiber strapping tape for easy transportation and inventory.
