Railcar Vibrators

The Rhino Railcar Vibrator Lifter

• The “Rhino” Vibrator Lifter removes the danger of inserting and removing heavy railcar vibrators and brackets into the cradle of hopper cars.

• The Rhino is powered by a pneumatic motor, which operates a hydraulic system designed to safely and easily maneuver the vibrator and bracket assembly into and out of the railcar cradle – all without any manual lifting by the operator.

• The vibrator operates off of the same pneumatic line, allowing the user to simply switch air power from The Rhino’s hydraulics to the railcar vibrator. Custom designed brackets allow the lifter to be used with roller railcar vibrators as well as piston railcar vibrators.
