Freight Car Door Openers

Plug Door Demon

The "Boxcar Bully" Freight Car Plug Door Opener is designed to open railcar plug doors without the danger of physical stress to the operator. The "Boxcar Bully" Freight Car Plug Door Opener can be operated from the seat of a fork truck/lift or from behind a pallet jack.


Portable Plug Door Opener

Unlike the "Boxcar Bully" Plug Door Opener which mounts to a forklift, the Door Demon® Portable Plug Door Opener is a stand-alone unit housed on its own easy-to-move cart. This Door Demon® is small enough to store (hide) anywhere yet durable enough to remove the violence and hardship out of opening even the toughest, damaged plug doors.


Portable Winch

The Portable Boxcar Winch will open the toughest railcar slide doors. The powerful winch rope delivers 6,000 pounds of pull to open bent and damaged doors. The pivoting anchor chain holds the portable unit in place for safe operation.



Double Winch - "Bully DR Winch"

The Double Winch freight car door opener is one of our most recent products.
