Welding and Track Maintenance Equipment

Battery-Operated Weld Shear EMB1/EMB2

Pandrol’s battery-operated weld shearing machines are designed for the easy removal of excess metal following an aluminothermic weld and is available in two variants.

The EMB1 is a narrow model, ideal for use in tunnels and closed environments, and the EMB2 is a wider unit, which is more comfortable for use when shearing through the mould. Both machines are rigid, powerful and designed to consistently deliver fast and accurate results. They are compatible with vignole and double-head rails.

Technical Features

  • The machines are powered by two batteries, using lithium HD technology which last for 12 shearing operations per charge, meaning there is no carbon emission during operation
  • The shear is fitted with two hydraulic jacks that are able to produce a force of 21 metric tons under a pressure of 250 bars
  • Two hydraulically-operated blades on either side of the weld move and cut off the excess metal, and five types of blades are available for different vignole rail profiles
  • A retractable locking system, fixed under the rail head, prevents the shearing machine from rising up in use
  • A manual lever controls a hydraulic distributor that allows the blades to move
  • The shearing machine comes in one piece and is lightweight

Advantages

  • The battery-operated shearing machine is fully autonomous, providing flexibility and freedom in the working environment
  • No emissions means it can be used in tunnels and closed environments
  • The shearing operation is extremely accurate, thanks to the adjustability of the blades and the guiding rollers
  • The accuracy of adjustments means that 2mm of weld metal can be left above the running surface, so the quality of profile grinding is not impaired
  • The shear is quick and powerful, minimising the time spent grinding the rail and maximising uptime
  • The machine is safe to use, lightweight and easy for two people to pick up and place on track
