PRODUCTS SERVICES INDUSTRIES SERVED SPARE PARTS FOR SALE OUR COMPANY CAREERS CONTACT US Above Grade Receiving Hoppers Compatible hoppers pair with truck and trailer dumpers for optimal material receiving. Airoflex above grade hoppers are designed to receive and reclaim large volumes of bulk materials such as woodchips, bark, pellets, sugar cane, hemp, and other similar flowable bulk materials. Our design eliminates the need for a high maintenance pit and extensive civil work. Altogether, adding an above-grade receiving hopper to your truck trailer dumper system will increase unloading efficiency at your facility, cutting down on time and cost. Our bolted hopper design minimizes the need for field welding, which results in lower installation costs. With safe operation and continued maintenance practices, our robust hoppers are engineered to have many years of trouble-free operation in addition to lower lifetime operational costs. The standard Airoflex above grade hopper is designed to integrate with our extended arm truck or trailer dumper. The truck driver backs the trailer into position on the tilting deck, and the material load empties into the hopper. Hoppers features a live-bottom floor with heavy-duty drag chain to convey material. Conveying capacity can be controlled by chain speed through a variable frequency drive (VFD) electric motor. This gives the operator complete control in adjusting reclaim capacities. A standard hood top contains and suppresses dust during the unloading process. To best suit our customer’s needs, we can configure a hopper using our modular accessories to suit any number of receiving applications.
