Closure Rail Puller, type CRP 160

Looking for a high-performance rail closure puller that can ensure optimal rail position while your team handles rail closure welding? Contrail Machinery provides you with the Closure Rail Puller, type CRP160, a high-performance hydraulic device designed for pre-tensioning the rails to be welded. In order to perform closure welds, this machinery is able to pull the rails together with a force of up to 140 tons for pre-tensioning the Long Welded Rail in order to be fixed at the neutral temperature

The CRP 160 rail puller is compatible with the CR100 flash-butt welding machine and it works by synchronising with the head during the welding process, helping it to pull the excess force required to perform the rail closure welding works.

Advantages of Closure Rail Puller, type CRP 160
  • The puller is connected through heavy-duty quick-disconnect couplings, so it can be easily installed or disconnected.
