With over 50 years of experience providing material handling equipment, the engineers at McCullough Industries have consistently applied science to design and build hoppers that are engineered for safety and economy. The Wright® Self Dumping Hoppers are perfectly balanced to roll forward when loaded, dump completely, and automatically return to an upright, locked position ready for reloading. Continuous welding helps to prevent leaks or drips. Top and pouring lips have formed smooth edges for added safety and strength. Extended sides prevent side-wise scattering of material.
