This design has improved safety and ergonomic in wheelbarrow. Wheelbarrow is a simple and useful product for caring things,but it has dangerous effect on users body because workers usually dont have enough knowledge about Anatomy and Ergonomic. They use their joints and vertebral column except muscles to carry the load. It seems be more dangerous for old workers. In this design the mechanism has changed. You push the handles down except pulling up and it cause the weight be on the wheel while youre caring the load.You dont need to use a lot of energy to push it down because the wheel is in the middle and the legs prevent from turning over
