Condition: good (used), Year of construction: 2014, Ref. no.: 18636 Manufacturer: EICHHOLZ Type: OCTABIN TIPPER & MATERIAL FEEDING SYSTEM Year of construction: 2014 Further information: WHAT IS AN OCTABIN TIPPER? An octabin tipper is an industrial automation system used for the controlled and safe discharge of plastic raw materials, granules, or regrind materials from large-volume octabin containers. Heavy octabins are loaded by forklift and then lifted and tilted in a controlled manner using a hydraulic or chain-driven mechanism. The material is discharged into the lower hopper and can then be transferred to the production line via vacuum conveying or dosing systems. These systems are widely used in plastic injection molding and extrusion plants to reduce labor, increase production efficiency, and ensure safe material handling.
