DESIGN OF ERGONOMIC CARRIAGE MATERIAL TRANSPORTATION FOR EFFICIENCY AND INCREASING PRODUCTIVITY

Abstract

The development of an industrial product arises with various problems and product quality that has high value. One example of a product that needs to be redesigned is a wheelbarrow or handcart. The wheelbarrow is a simple material conveyance which is pushed by hand, one wheel and one operator through the handle. This research aims at an ergonomic and economical handcart, so as to produce a product that can be useful for medium-sized industries and can increase efficiency and increase work productivity. This research was carried out by redesigning the product as a development, where this product is usually used in a building called a traditional material conveying tool, then calculating the axle and pedal stress on a wheelbarrow. In this study it can be concluded that the wheelbarrow or wheelbarrow is designed more ergonomically with several changes including changes in the height of the stalk from the ground to minimize bending when lifting the wheelbarrow, changes in shape and size of the supports to accommodate various lifting positions, other things, changes in shape and the size of the body so that when lifting and pushing the wheelbarrow, the load is more balanced, the addition of a jack to make it easier for users to spill loads from the body, the addition of two rear wheels to make it easier to push the wheelbarrow, and change the handle to make it easier for users
