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.
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.
