Main Article Content
Abstract
This study presents an alternative design for handling sago bags, focusing on creating a user-friendly platform for loading and unloading. Sago is packed in canvas bags of varying loads (15 kg, 25 kg, and 30 kg), which poses challenges due to its non-uniform distribution and can lead to stability issues during transport. The study proposes an assistive device made of durable, tough, and resistant materials such as HDPE, PP, ABS, and Polyester, offering a balance between hardness and solidity. The device’s standardized size allows for easy connection and application with the forklift lever, with a simple design for easy maintenance and part replacement. The elastic properties of polymer materials enable deformation during heavy load handling, crucial for shock absorption in a stackinglike building style. Rubberized shoulder straps enhance grip and durability. The device can be folded into a compact size (109 cm Î 30 cm Î 10 cm) for easy stacking and storage. The handle features a rubber grip for comfort, and the side belt is made of 1.5 mm thick polyester, designed to accommodate 50% and 100% capacity. The base, 1 mm thick, is constructed from polypropylene (PP) and measures 109 Î 120 cm, ensuring a robust and efficient solution.
