Abstract
A hand cart provides a handlebar attached to a wheeled frame upon which is disposed a platform for carrying loads. Independently slidable sides surround the platform, providing walls to prevent loads from sliding off the platform. Some embodiments of the invention enable raising and lowering the platform. Embodiments provide user-operated normally engaged braking. A suspension system facilitates cart transport, keeping the cart generally level on uneven surfaces and enabling front and rear wheels to pass over barriers.
