The GO-M04 generates an operator-paced output of 400 ft-lbs which can be increased 10X with an HD Pipe Extension.

The WORKMASTER® GO-M04 Gate Opener is a manual-powered, hand portable, compact Railcar Gate Opener that utilizes a 1-1/2″ sq dr, extreme-duty, ratchet wrench to enable an operator to generate a no-torque reaction power output of 400 ft-lbs with its standard 30″ handle (handle & ratchet head OAL: 36″). The GO-M04 Railcar Gate Opener’s ratchet mechanism can accept up to 5,000 ft-lbs of input torque so the handle can be lengthened using a heavy walled 2″ ID pipe to increase the M04’s “breaker bar” power. Because the GO-M04 uses a 4-sided, tapered drive fitting to turn the capstan, the dangerous slippage problem that occurs using a pry bar is eliminate. The GO-M04 is the ideal Railcar Gate Opener when budget is limited and hopper car unloading is infrequent.
