Arnold Dual Roller Pneumatic Roller Railcar Vibrator with Handle and Wedge Bracket: Max Working Force of 7100 lbs at 90

Arnold’s line of pneumatic roller railcar vibrators offers a full range of frequency and force. With only three internal moving parts, these hopper railcar vibrators have an extended life and require minimal maintenance.

HOW IT WORKS
Air pressure activates the multi-slotted vane on two rollers (one within the other) which creates multiple vibrations on each orbit; this produces a powerful force at a high frequency.

INCREASED UNLOADING EFFICIENCY WHEN USED WITH THESE COMMODITIES SHIPPED VIA HOPPER RAILCAR
• Agricultural and Food/Beverage Commodities: potash (fertilizers), urea (fertilizer), corn, soybeans and soybean meal, wheat, sorghum, and distillers dried grains and solubles (DDGS)
• Aggregate/Mining Commodities: salt, coke, crushed stone, sand, gravel (up to 1/2″), limestone, cement, iron ore, gypsum, and frac sand
• Many Other Commodities

Features:
• This series of roller railcar vibrators and shaker solutions is the industry standard for hopper railcar unloading
• Mounts easily to most standard wedge brackets for use with hopper railcar pockets
• There are no bearings, seals, or O-rings
• 3 moving parts (vane, roller-vane, inner/outer roller) provide for simple, long-wearing vibration requiring minimal maintenance
• Shaft, roller, and endplates are hardened and ground to assure high performance and reduced wear
• Frequency ranges between 2000 and 9000 vpm depending on the type of railcar vibrator and air pressure applied
• It produces a powerful output force ranging from 1000 pounds up to 7500 pounds
