Iron Elbow and Straight-Chain Tool to Reduce Slip on Wood Transportation: An Experimental Study

Abstract

Abstract. One of the obstacles in transporting wood is the occurrence of slippage. Slippage results in low productivity of timber transport with high production costs and soil damage. The research method is an experimental approach, namely designing, manufacturing and testing the supporting tools in the form of angle iron and straight iron chain. The research objective was to determine the effect of the use of assistive devices on slippage, productivity, wood transport costs and soil damage. The results showed that: 1). Tools from the wheelbarrows of the conveyance wheel from the straight iron chain of the slope class 0-8%, 9-15%, and 16-25% can minimize the occurrence of slippage higher than not using this tool, increase the wood transportation productivity, low transportation production costs, and minimize soil damage; 2). Elbow iron and straight-chain tools are the most efficient and effective. 3). The use of tools in the transportation of wood in slopes 0-8%, 9-15%, and 16-25% is recommended for smooth production.
