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.

Welding Process of Overhead Crane Rail Joint

Welding Process of Overhead Crane Rail Joint In order to make the overhead crane rail transport more stable, rail splints will not be used for the overhead crane rail joint connection, but welded joint connection will be used. The main key to the welded joint is to solve the bending deformation and weld cracking of the overhead crane rail joint. During the welding process of the overhead crane rail joint, the overhead crane rail joint is deformed downwardly, so the overhead crane rail end must be padded to a certain height before welding to ensure that the rail joint can be kept straight after the welding is completed. The height of the rail end pad is determined by factors such as the type of rail, length, fixing method and ambient temperature. The rails are fixed to the crane beam by means of hook bolts, and each joint is provided with four fixed points. After the bottom of the rail is welded, reduce the height to 20mm, and then tighten the hook bolts to continue welding. When the o...

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...
