What Are The 4 Types Of Railway Fish Plates？

Why it is safe to use rail fishplate?

Take Indian fishplate for example, 1 piece of fishplate minimum tensile strength is 5.58-6.51 t/cm2 and 20% elongation. Fishplate was designed to have same strength of steel rail section. One piece of rail section is about 55% of rail sections, so 2 pieces fishplate is more stronger than steel rail profile.

GNEE RAILWAY is a professional manufacturer providing high-quality railway fasteners including fish plates, rail clips, railroad spikes and some other fasteners. Our company exports to 200 countries and regions and gains high reputation. We mainly produce the following types of fish plate, common fish plate, joggled fish plate and compromise fish plates,insulating fish plates.

1,Common Fish Plate

We offer 4 holed or 6 holed rail fish plates to suit 60 kg, UIC, 54 kg UIC, 52 kg UIC, 52 kg, 90A, 90R, 80A, 80'O', 88'O', 75R, 60R, 115 RE, 132 RE, 50R rails, etc.

Common railway fish plates can be divided into four holes and six holes. The materials of railroad fish plates can be divided into nodular cast iron, Q235 rolling steel, forging steel and so on. In general, railway fish plate production applies medium carbon steel and high carbon steel as the raw material. In addition, we can also produce composite railway fish plate, cast iron railway fishplate rail joint and cast steel railway fish plate.

The normal track fish plate is the most common type, which is widely used in various kinds of rails. It is ordinarily made of medium carbon steel and high carbon steel. And there are two types of normal fish plate, four holes normal fish plates and six holes normal fish plates. The fish plate in railway track is used in conjunction with the fish bolt. The fish bolt penetrates through the elliptical hole, and the protrusion at the end of the bolt coincides with the elliptical hole, playing the role of fastening. The normal fish plate has the simplest structure among all kinds of them, which widely be applied in the railway tracks.

2,Joggled fish plate

Joggled rail fishplate is used while rail joint maintainence or emergency repairs, it has unique shape to leave space for welding steel rails with defective. Mostly applicated in seamless steel rails, it is a necessary part in keeping rail joints safety when there is hidden danger.

Joggled fish plate is another type of fish plate, that has the same function as the normal fish plate. The joggled fish plate is different in shape from a normal fish plate. it is a special forged fish plate that includes a fish plate and a bulge section in the middle. The joggled fish plate can effectively clamp and repair the welded steel rail, allowing the train to pass through the railway track safely. It has the characteristics of following rail deformation, a wide range of applications, convenient maintenance, durability, simple installation, and excellent fatigue resistance.It can reduce the impact of wheels on rail joints, increase the continuity of longitudinal deformation of rail joints, and improve the flatness of trains passing through.

This product is a specially forged fish plate. It is suitable for the temporary repair of cracked welded rail joints with clamp assembly to suit various rail sections. Used as an emergency clamp, joggled fish plate enables quick and temporary repair, allowing continued movements through the section at a reduced line speed. AGICO production capablity can meet your ergent order with in short times.

3,Compromise Fish Plates

Compromise rail fish plates are used to connect abnormal rails, which have two separate pieces- one piece installed in the outside of rails, another installed in the inside of rails. Compromise railway fish plates are specially designed to smoothly match the gauge-head face of two rails, one set compromise railroad fish plates are consisted of four bars.

Compromise joint bar and related rail fasteners has wide applications in the railway lines, such as connection between railway switch and main track line, other types of rail connections. Generally, compromise joint bar is applied to 50kg and 60kg, 43kg and 50kg rail tracks.

4,Insulated Railway Fish Plate

We can also supply insulated railway fish plate. As its name, insulated railway joints is made of insulating material, a new type of high strength composite track material. It has the features of corrosion resistant, rust protection, ultraviolet-proof, non-conducting and non-magnetic. What's more, insulated railway fish plate is a thermosetting material and cannot be reprocessed, so it is burglarproof.

The insulated rail joints are bolted rail joints containing bonded insulation materials wrapped around each contacting surface to electrically isolate them. The insulated rail fish plates are all made of insulating materials. Most of the insulated track fishplates are made of high-strength composite materials. They have the features of corrosion resistance, rust resistance, UV resistance, non-conductive performance and non-magnetic performance. In addition, they should be made of a thermosetting material and cannot be processed twice. So they are not afraid of theft.

Types of the insulated rail joints

The type of the insulated rail joints can meet different steel rails:

A. Light rail: 8kg, 12kg, 15kg, 18kg, 22kg, 24kg, 30kg

B. Heavy rail: 38kg, 43kg, 50kg, 60kg, 75kg

C. Lifting rail oblique joint: 43kg, 50kg, 70kg, 80kg, 100kg, 120kg

Model and theoretical weight of the insulated rail joints

9KG refers to 0.81kg; 12KG refers to 1.39 kg; 15KG refers to 2.20 kg; 22KG refers to 3.80 kg; 30KG refers to 5.54 kg.
