Product Introduction
The railway fastener system is a complex and precise track connection device, which consists of sleeper bolts, spring clips, rail pads and other components. It can be divided into categories such as trunk railway, urban rail transit and heavy-duty railway according to the application scenario. In the field of trunk railway, SKL series fasteners provide stable support for conventional railways with mature technical systems; in urban rail transit, Nabla greatly reduces the impact of train running vibration on surrounding buildings; KPO heavy-duty fasteners commonly used in heavy-duty railways adopt thickened spring clips and thickened bolts, and a single fastener can withstand up to 30 tons of axle load.
Nabla Spring Blade is one of the core components of Nabla Fasteners System.
Material: Usually made of alloy spring steel such as 60Si2MnA, 60Si2CrA. These materials have good elasticity, strength and toughness, can withstand long-term train loads and vibrations, ensure that the spring leaf is not easily deformed and damaged during use, and thus provide stable and reliable fastening force.
Working principle: When the nut of the Nabla Fastener System is tightened, the spring leaf will produce elastic deformation, generate dynamic and stable buckling pressure on the rail, and firmly fix the rail to the sleeper or pad to prevent the rail from lateral or longitudinal displacement during the train operation. At the same time, it can also absorb and buffer the vibration and impact force generated by the train passing, reduce damage to the track structure, and ensure the stability and safety of the track.
Product Specifications
Product Packaging & Delivery
The plastic turnover box is designed with a double-layer structure. The upper layer is a transparent compartment box for storing small accessories. The lower layer has a larger space and a spring shock absorber installed at the bottom, which is suitable for medium-sized fasteners. The two layers are separated by a partition with a sealing strip, and the box cover is locked with a rotating buckle. When multiple boxes are stacked, the card slots on the side of the box are precisely connected with the protrusions, and finally they are surrounded and reinforced with plastic strapping to meet the needs of transporting multiple specifications of goods in the same box.
