  • Three-wheel cargo cart with adjustable handle height
    Patent number: 10919554
    Abstract: A hand propelled three wheeled cart for transporting miscellaneous cargo. The basic cart has a single front wheel with two solid rear supports, such as a standard wheelbarrow. The two rear wheels are attached to a lever that is pivotally connected to the lever mounting support brackets. Lifting the handles pries the two rear wheels, into position, elevating the rear cart support legs off the ground. This cam action reduces the operators lifting effort and improves the lateral stability of the cart. Releasing the handles automatically anchors the cart.
