Martin Engineering has introduced the two-wheeled Gen 4 Railcar Opener, which delivers controlled, non-impacting power to open and close even the most difficult railcar gates. 

It features simple maneuverability and lateral turning wheels for moving capstans, outrigger support and height adjustment. Additionally, the “stepped” drive tip improves the gate opener’s contact with the capstan. This new design leads to less demurrage from stalling and a safer workplace.

Railcar openers are semi-automated systems controlled by a worker to enhance the speed, efficiency and safety of unloading materials. A cargo train generally offloads into a storage facility or conveyor by dropping cargo through an underside opening sealed with a gate. A capstan connected to a shaft and pinion gear is used to open the gate. A poorly maintained gate will require a great deal of force to open. Since most facilities do not know the condition of the gates upon arrival, it is advisable to have an opener that has some range. The Gen 4 will generate the power necessary to open and close gates safely and without damage.  

Gen 4 allows adjustment of the driveshaft height to match various rail car capstan heights and to account for variations in unloading platforms. Fitting through 36-inch-wide door frames, the unit’s outriggers expand up to 67 inches (1719 mm) for greater stability during high torque operations.
