What are the types of rail joints?



Rail Joints also called railway fish plates or joint bars, or splice bars is a metal joint bars connected to the ends of two rails to bond them together. A quality rail joint bar can largely reduce the impact of wheels on the jointing sections of the rail tracks. And increase the continuity and steadiness of the train when passing through the jointing sections. These rail components are guaranteed railroad transportation safety no matter whether it’s light or heavy.

Types of rail joints

We supply more than 30 types of rail joints, according to different standards:

Rail joints for light rail: 8kg, 9kg, 12kg, 15kg, 18kg, 22kg, 24kg and 30kg

Rail joints for heavy rail: 38kg, 43kg, 50kg, and 60kg

Crane rail joints: QU70, QU80, QU100, and QU120

To ensure the fine use of railroad equipment, we need to maintain the rail joints from time to time in order to improve quality and avoid any accidents.

Assembling and maintenance standards for rail joints:

STEP1: Check if the bolts are well fastened and make sure no wounds or cracks on the surface

STEP 2: Keep each connecting rod and locking device clear from cracks. No grinding or corrosion on the rod body or abrasion pinhole less than 1mm. Good insulation shall be maintained.

STEP 3: All iron rod connections with good insulation. The insulation link between the locked iron and gauge rod are both fine. In uninsulated conditions, a 3mm gap should be kept and not into other parts. And bolts are fastened well.

STEP 4: Ensure no cracks on the shell of the switch machine to assemble rail joints, and the installation is firm under good lock condition.

STEP 5: Ensure the oil tank circuit is in good protection without damage or being buried by ballasts or other debris.

What are railway rail fasteners?

What are railway rail fasteners? Railway rail fasteners Railway rail fasteners are a kind of railway accessories. The parts used to combine rails and sleepers (or other types of under-rail foundations) on the track are also called central joint parts. Its function is to fix the steel rail on the sleeper, maintain the gauge and prevent the longitudinal and lateral movement of the rail relative to the sleeper. The railway rail fastener system is divided into the shrapnel fastener system, gusset fastener system, and elastic strip fastener system. The gusset-type fastener is composed of a gusset plate, a threaded spike, a spring washer, an iron seat, and a buffer pad. The threaded spike is anchored in the reserved hole of the concrete sleeper bearing platform with sulfur cement mortar, and then bolts are used to fasten the buckle. Plate fastened. There are elastic strips I, II, and III types of clip fasteners. Type I elastic strip is composed of ω elastic strip,  screw spike , gauge b...

30 LB RAIL FOR SALE

  30 LB RAIL FOR SALE What is a 30 lb rail? A 30 lb rail refers to a rail weighing 30 lb in meters, which is an ASCE 30 model rail produced according to ASTM A1. As a common light track, it is mainly used for laying mining track lines. Therefore, it is widely used in the South American market. The dimensions of the 30 lb rail are as follows: Head width: 42.9mm Track height: 79.4mm Track bottom width: 79.4mm Waist thickness: 8.4mm GloryRail is an important  mining rail  supplier in China.

We maintain long-term cooperative relationships with many important customers in Peru, Colombia, Panama, and Venezuela in South America BUY 30 LB RAIL FROM CHINA As the world’s most important rail tracks production base. There are six major steel mills in China producing rails with an annual output of millions of tons. G...
  What are seamless rails? seamless rails Continuous seamless rails, also known as a welded long rail line, is a line that welds ordinary rails without leaving rail seams. meters or longer. The long rails are laid and fixed on the sleepers within the specified temperature range. There are rail slits at the end of the long rail, and the middle part cannot expand or contract with the temperature rise and fall. Therefore, the middle section of the steel rail will generate a large temperature pressure in summer and a large temperature tension in winter. The large pressure and tensile force in the rail can be calculated according to the annual high and low temperature of the place where the rail is laid. The large pressure on the rail should not cause the rail to buckle, and the large tensile force should not cause the rail to break. The seamless rails line greatly reduces the  rail joints , reduces the impact on the rails when the wheels pass through the joints, is conducive to s...
