The handle should also be positioned at a height and angle that is comfortable for the operator to use, with consideration given to the operator's height and reach. Pumping Effort: The design of the pump should be such that the amount of effort required to operate the pump is minimized. This may involve selecting an appropriate gear ratio for the crank handle, a longer handle or designing the pump components to minimize friction and resistance. Weight and Balance: The weight and balance of the pump should be optimized to ensure that it is easy to lift and manoeuvre. The pump should be designed to be well-balanced, with consideration given to the weight of the pump components and the distribution of that weight. Access and Visibility: The design of the pump should allow the operator to easily access and see the pump components (Chrimes, M. and Preene, M., 2021). This may involve designing the pump housing with clear windows or other features that allow the operator to see the pump mechanism or designing the pump with easy-to-access maintenance points. Noise and Vibration: The design of the pump should minimize noise and vibration to reduce B operator fatigue and improve comfort. This may involve using vibration-damping materials, designing the pump to operate at a lower frequency, or incorporating other noise and vibration-reducing features. Overall, the design of a hand-crank pump should prioritize the comfort and safety of the operator. By considering the ergonomics outlined above, designers can ensure that the pump is easy and comfortable to use and reduces the risk of operator fatigue or injury.
