Valley Craft's 1/2 cu. yd. Auto Lock Hopper is constructed of heavy duty steel and features watertight continuous welds - two fixed and two swivel 6 inch casters - tapered front to help initiate dumping and a load capacity of 2,000 lbs. When paired with the Hydraulic EZ Dump Fork Lift Attachment - this Hopper System increases productivity and lowers overhead expenses by reducing employee downtime and decreasing the number of fork lifts needed to complete jobs. The EZ Dump mobile hoppers allow employees to move aside fully loaded hoppers to await fork lift pickup while rolling in an empty hopper to continue production uninterrupted.
