Product Introduction
As an important component to ensure the normal operation of railway tracks, the railway fastener system consists of spring pieces, rail pads, anchor parts, washers, etc. It can be divided into light, medium and heavy fastener systems according to the load-bearing capacity of the track. The light system is suitable for branch lines and industrial railways with small traffic volumes to meet basic track fixing needs; the medium system is suitable for general trunk lines and can withstand the load of medium-volume trains; the heavy system is designed for heavy-load railways, and with its superb load-bearing capacity and stability, it can cope with the frequent crushing of 10,000-ton trains.

As the intermediate connecting part of the railway track structure, the design and construction of Nabla Clip for Nabla Rail Fastening System fully consider the actual application needs. The buckling mechanism of Nabla clips can continuously maintain stable constraints on the rails when the train is running; the presence of insulators eliminates the risk of current leakage; and high-strength connecting components ensure the integrity of the system structure. In view of the different characteristics of ballasted and ballastless tracks, the system can be flexibly adjusted and configured. It shares the load with the ballast in ballasted tracks and cooperates with the elastic cushion in ballastless tracks to always maintain the correct geometric position of the track and ensure the comfort and safety of train operation.

Product Packaging & Delivery
For large and heavy fasteners, a removable metal frame is used for fixing. First, the fastener is placed in the center of the frame and clamped with an adjustable hydraulic clamp. Universal wheels are installed at the bottom of the frame for easy movement. Then the frame and fastener are wrapped with waterproof canvas, and the edges of the canvas are fixed to the frame with metal buckles. Multiple frames can be stacked for transportation and fixed in series with chains to ensure stability and safety during handling.
