Martin Engineering improves Railcar Opener

(Neponset IL)-To improve the unit's ability to stay in contact with railcar gates featuring rack-and-pinion opening mechanisms, Martin Engineering, the leading international supplier of systems and services to improve the handling of bulk materials, has introduced an improved version of its MARTIN® Railcar Opener.

Used to open the discharge gates on bottom-dump railroad hopper cars, the MARTIN® Railcar Opener will improve unloading efficiency and reduce safety risks for personnel.

The improved MARTIN® Railcar Opener features pivoting wheels that allow the unit to roll along the track to maintain contact with the traveling capstan of rack-and-pinion on AAR S-233-92 standard hopper car gates.

The MARTIN® Railcar Opener provides 2700 ft-lb (3661 N-m) of torque at 90 psi (6.2 bar) to open the most stubborn hopper car gates. The output force is smooth and non-impacting to open gates without damaging car mechanisms.

The MARTIN® Railcar Opener adjustable cart base allows one worker to maneuver the opener through tight spaces. Unit height can be adjusted to meet the gate mechanism regardless of ground conditions at the unloading site.

Martin Engineering offers other technologies to improve the unloading of bottom dumping hopper cars. BOOT-LIFT® Railcar Connectors funnel material to a plant's under-track system, preventing wind loss and eliminating the safety hazard of requiring workers to crawl under the railcar. MARTIN® Railcar Vibrators boost the flow rate of materials compacted by long-distance travel.
