The GO-B3A Battery Powered Gate Opener generates an 2 RPM paced power output of 3,000 ft-lbs of Torque.

The WORKMASTER® GO-B3A Gate Openeris a battery-driven, torque-controlled, portable power tool that produces up to 3000 lbs-ft of torque to open hopper car gates that are easy to moderately-dicult to open. Although the Opener, at 35lbs, is compact and lightwieght, because it is a torque wrench, it does require the use of an easy to attach torque reaction arm for safety. The GO-B3A is supplied with two (2) long lasting HD Lithium-Ion batteries which, if properly maintained, will open hundreds of hopper cars for
years.

GO-B3A Gate Opener

The GO-B3A Hopper Car Gate Opener is well suited for worksites that experience:

  • Unloading sites that receive occasional to light hopper car traffic;
  • Railcars that vary from easy-to-open to moderately difficult;
  • Neither compressed air or electric power is available or is limited;
  • Majority of railcars have fixed position gate mechanisms;
  • Trackside surface is level, smooth, and unobstructed;
  • Narrow decks or platforms preclude wheeled-cart or beam-mounted Opener;
  • Site security requires portable, easy to remove and store tools.
