Combined with a multi-dimensional tub design, the SnowEx Helixx system vastly outperforms traditional augers and delivers unmatched material flow. It also offers the triple threat capability to spread, pre-wet and spray with one machine. The corkscrew (helix) design of the patent-pending Helixx material delivery system is optimized for efficient and cost-effective use of salt and was engineered to operate in the target range for salt spreading best practices. Whether spreading 100% salt, 100% sand, or any mix in between, the Helixx is engineered to prevent clogs and provide a flow of material superior to that of traditional auger spreaders. Designed for use with full-size pickups, flatbed trucks or dump-bed trucks, the Helixx poly hopper lineup includes four different models, ranging in capacity from 1.5 to 5.0 cubic yards. The hoppers are supported by a corrosion-resistant stainless steel frame that features a unique leg and sill design to form a ridged backbone structure for greater durability. For quick installation and removal, fork pockets are built into the legs.
