Lever is a new wheelbarrow design for the construction workers. The occupational injuries rate in construction workers is the highest among all the careers. The main cause of injuries is from over loading and repeating the same motion. The existing wheelbarrows mainly focus on transporting materials without good human behaviour consideration. As a result, the unpredictable loses of man power and healthy life for the both construction company and the workers are confusing the industry nowadays. Lever is design to reduce the risk of getting hurt in the waist while the construction workers are using wheelbarrow. On the other hand, thank you to the gyroscope technology, the working efficiency is improved up to 30% by the easier control.
