Product Introduction
SKL fastening system is a commonly used fastening system in railway track construction, and SKL spring clip is a key component in SKL fastening system.
SKL fastening system usually includes SKL spring clip, rail pad, sleeper screw, plastic sleeve, gauge block, washer, etc. Different types of SKL fastening system, such as SKL12, SKL14, etc., differ in specific structure and application scenarios. For example, SKL-12 type is commonly used in ballastless track and belongs to the sleeper track plate separate fastening system. Its rib plate is provided with independent screw holes at both ends, which are connected to the railway sleeper or track plate by fork bolts; there are T-bolt insert seats and shoulders on the rib plate, and the elastic clip is fixed by tightening the nut of the T-bolt; horizontal and lateral adjustment is achieved by using eccentric taper pins of different sizes.
SKL spring clips are the buckling parts of elastic fasteners. They generate buckling pressure on the track through their own bending and twisting deformation, effectively ensuring the reliable connection between the rails for a long time, maintaining the integrity of the track as much as possible, preventing the longitudinal and lateral movement of the rails relative to the sleepers, ensuring the normal track gauge, and thus ensuring the safety of rail vehicles. At the same time, since the contact between the train wheels and the rails is rigid contact, vibration is inevitable, and the special elastic structure of the spring clip enables it to absorb the impact energy generated when the vehicle passes by and achieve the effect of shock absorption.
There are many types of SKL series spring clip track fastener systems, such as SKL1, SKL3, SKL12, SKL14, SKL15, SKLB15, etc. They are generally made of high-quality spring steel, such as 60Si2MnA, 60Si2Cr, 38Si7, etc. These spring steels have the characteristics of high strength, high toughness, good elasticity and fatigue resistance, and can meet the working requirements of SKL spring clips to withstand huge pressure and impact force on railway tracks for a long time. The manufacturing process usually goes through forging, heat treatment, surface treatment and other processes to ensure the performance and quality of the spring bar. Common surface treatment methods include natural color, blackening, baking varnish, galvanizing, Dacromet, etc., which can improve the corrosion resistance and wear resistance of the spring bar.
Product Packaging & Delivery
or the packaging of the fastener system before shipment, first stack the fasteners of the same batch neatly on the pallet, and lay corrugated cardboard between the layers. Use high-strength stretch wrap film to tightly wrap it from the bottom of the pallet upwards, and tighten it after wrapping it to the top. Add L-shaped paper corner guards to the four corners of the pallet and fix them with tape, and then use horizontal and vertical strapping tape to reinforce the paper corner guards and the pallet as a whole to form a stable transportation unit.
