“A consistent and frustrating problem we ran into was clogging issues on the hopper trucks,” Bill Noeske explained. “Whether it was seed or any other cargo, the road vibration caused the material to compact at the chute mouth, so during offloading our drivers would spend hours completely emptying the trailer. They would have to get under the truck to poke at the plug or get on the truck and pound at the wall, and it would still not dislodge all of the material that clung to the sides. It was unsafe, frustrating and costly.”
Seeking a solution, the Noeskes reviewed various options, including permanently mounted vibration units. “One of our trailers already had dealer-mounted vibrators at the slope, which worked okay, but we needed more versatility,” Noeske pointed out. “To access all parts of the trailer we purchased one MT-FAST Vibrator from Martin® Vibration Systems, and it worked so well that we bought two more for the remaining trucks that weren’t equipped with vibration.”
Powered by a rig’s onboard compressor, the vibrator suctions securely to any flat surface of the trailer using a patented vacuum mounting system. Requiring less than 15CFM for effective operation, the lightweight unit delivers 200 lbs of linear force. Well suited to large particle sizes and low bulk density materials, such as grain, meal and other agricultural products, the low-frequency, non- impacting energy loosens stubborn loads without damaging the hopper. Weighing in at only 8 lbs, the units are explosion-proof and washdown-safe.
With fast spot-to-spot mobility, operators are able to apply the proper vibrational force at any point on the trailer to dislodge bridged or clinging material. All hoses and connectors are supplied with the unit. No assembly is required.
Since they’re not limited to a bracket on the knock rails, the units can be positioned at corners, valleys or other problem areas where material flow tends to stall. And because they are affixed directly to the hopper wall, energy is transferred more efficiently than with a permanently-mounted vibrator on a bracket.
“Our drivers tell me they’re asked about the vibrators all the time by other drivers who are stuck pounding and poking their loads, while our people are unloading and driving away within a few minutes,” Noeske said. “There are some friendly disputes within our crew over who gets which truck, because the Martin units work a lot better than the permanently-mounted vibrators.”
