Railroad spike is the main component in rail fasteners. It is used to fasten railway sleepers or rail ties in the rail track and plays an important role in ensuring the stability of railroad. The obvious features of track spike are the offset head, flat edge point and chisel, which makes the spike resist to loosening.
Railway workers often use a tool - railroad spike puller, which can be used to pull out the railroad spike in the sleeper in the saving effort way.
Another relevant tool is railroad spike hammer, which is used to hammer the railway spikes into the railroad ties. Railroad spike is short for metal spike for railway track. The function of the spike is fixing railway track and making the subgrade of the railway track have a better ability to under pressure.
Railroad spikes as the railway accessories are commonly used in railway track facilities, which were generated in early time and developed following the continuous upgrade of the railway track. Now the commonly kinds of domestic rail spikes include wood screw spike, spring spike, screw spike, conventional spike etc.
AGICO Rail Fastener supplier can not only provide these rail spikes above but also can design railroad spikes by drawing. The usage mode of the various railroad spikes is different but the functions are almost the same because different structures are all used to impact on the railway track.
Common conventional rail spikes are divided into manual spike and machine-made spike. The process of installation and usage of two kinds of spikes are very simple and the rail spikes can be fixed by spike hammer. Manual rail spike are made by hand and thus have varies sizes. But the price of them is lower and generally sold by tons. Machine-made spikes are made by the process such as forging, heat treatment and thread chain. Regardless of the shape, size and availability they are the best choice in spite of higher price. The machine-made spikes are generally sold by units.
But the production process of two kinds of railroad spikes is different. The process of common manual railway spike is an earlier process of the spike producing. This mode of production is used by manual forge way, making hot embryo shape of railway spike. So using this production process to make railroad spike itself exists some shortcomings, for example, part of the rail spike surface will raise or have rough selvedges, and its weight will have positive or negative deviation.
Compare to the manual railway spike, machine-made spike can avoid these problems very well. The railroad spike production process is the combination of manual and mechanical mode. Commonly machine-made spikes have smooth surface and each of them has little deviation. Therefore railroad spike can be produced batch production more effectively and there will be no high defective rate problem which commonly exists in manual spike.
The material of AGICO machine-made spike is carbon constructional quality steel and rail track steel as raw material. It is forged averagely and shaped by machine. The size outside and the quality inside meets the government standard well.
