Abstract

A wheelbarrow is a carrier, having only one wheel and consists of a try bolted to tow handles and two legs. Use as device for carrying small loads for a household gardener, a wheelbarrow also used in construction and industry for carrying larger loads (Kallie, 2019) Wheelbarrows are human-powered carts with one wheel to assist in carrying all kinds of burdens, from harvested crops to mine tailings, and pottery to building materials. Problem occurs during wheelbarrow pushing may have a high risk of overexertion (Datta, 2001) User have to apply 57% and 23% more force in the vertical and horizontal direction while pushing one-wheeled wheelbarrow. Muscular activity increased significantly in the dominant hand with the one wheeled wheelbarrow. (Godilano, K, & A., 2018). The design is composed of two hydraulic dumper real type absorber at back of container, two non-pneumatic wheels in front. With the help of the two additional wheels, the stability problem of the conventional wheelbarrow was resolved. In designing a product, ergonomic aspects such as working posture, energy consumption, conditions of environment, safety and usability need to be considered. These features emphasized in the design of this wheelbarrow-on the-go. A few improvements will be made on the design of wheelbarrow. Among new design innovations will be done are: front lift system to allow the bucket dump independently from the rest of the wheelbarrow, hydraulic dumping real gas absorber with two tires for more stability. Wheelbarrow-onthe-Go comes with improvement in terms of number of tires, simple design of wheelbarrow and pneumatic dumping system compared to an existing product in market. It more convenient to be used by workers which is 20% time saving for works can be transfer and done compared to manual wheelbarrow and manpower. Wheelbarrow-onthe-Go can lift load maximum up to 50 kg.
