GWJ Type Rail Joint Holeless Clamping Device

GWJ Type rail joint holeless clamping device is suitable for emergency processing broken rail or damaged weld joint, and also is used as temporary connector in continuously welded rail track (cwr) laying operation. Among the devices, GWJ-60 and GWJ-60(D) are suitable for temporary connecting 60kg/m rail, GWJ-50 and GWJ-50(D) are suitable for temporary connecting 50kg/m rail. While adopting this device, it's unnecessary to drill hole at the rail web, and the rail joint resistance is massive. The device possesses nut loosening installation. It features quickness in manipulation, safety and reliability, small maintaining amount and economical advantage. It's an ideal rail joint clamping device.

Method of operation

The device can be employed as one pair or three pairs (fishplate), also can be used as two pairs combinedly (bulge splint). While operating, first adjust the distance between the rail gap (crack) and the sleeper at the both sides. Push aside the ballast under the rail, put in the fishplate at the rail web. Place the chuck groove bevel on the rail base bevel, insert the bolts. Screw down the nuts at both ends repeatedly to the rated torque at the same time, lay down the loosening plate.

While using one pair: visually align the clamping body (breadth) center with the rail gap (crack).

While using three pairs combinedly

While installing three pairs (GWJ-60,GWJ-50): first adjust the distance 360mm between the rail gap (crack) and the sleeper at the both sides (The sleeper center distance is about 720mm.), visually align the clamping body (breadth) center with the rail gap (crack). The space between the left or right clamping body and the middle clamping body is 25mm.

While installing three pairs assembly (GWJ-60 and GWJ-60(D), GWJ-50 and GWJ-50(D)): visually align the clamping body (breadth) center with the rail gap (crack). The space distance between the left or right clamping body{GWJ-60(D)} and the middle clamping body is 10mm. While screwing down the nuts at both ends, it's forbidden to allow the left and right clamping body being deflecting.

While installing two pairs (using bulge splint): place the bulge splint at the rail web of the rail gap (crack). The space distance between the inside edge of the left or right clamping body and the weld seam is 110mm.

C. Removal method

1.While disassembling the clamping body, first turn up the loosening plate, insert the pull pin to fix the loosening plate.

2.Loosen the nut at both ends. Anyway, don't allow the nut to separate from the bolt.

3.Knock the fishplate and the clamping body side surface, loosen the nut at both ends as the clamping body is loosened, dismantle the clamping body.
