At McCullough Industries, we carry a wide range of material handling systems, supplying our customers with durable products that can endure years of heavy use. The Wright GEN II lines of standard, self-dumping hoppers are engineered with versatility in mind, with over 30 models to choose from.
The GEN II series features capacities that range from ¼ yard all the way up to 6 yards. With such a large selection, dimensions and specifications vary greatly. However, all GEN II hoppers are manufactured with heavy steel construction, 3” fork opening, low center of gravity, and a compact footprint. To learn more about Wright hoppers, contact us directly.

Note: All dimensions are approximate some dimensions may vary slightly per hopper.
