The compact and simple design makes the flash-butt welding equipment kit, type CR65 extremely easy to operate and maintain.
In addition to the standard rail, the CR65 head can be used in welding grooved rails and crane rails (electrodes and shearing dies will be designed accordingly).
The rail welding equipment, type CR65 is very light, weighing only 3 tons and develops an upsetting force of 65 metric tons.
The welding head jaws are optimized and tested to withstand long-term fatigue, the new design offers a firm clamping capability and a solid structure of the whole mechanism.
The alignment of the 2 outer vertical reference blocks is easily done by a mechanical adjustment system, ensuring a precise movement up or down.
With the new type of electrode, the flash-butt welding equipment kit, type CR65 can weld rails with different profiles only by changing the contact pads (inserts). With a single type of electrode block, up to 3 types of rails can be welded.
