An improved braking system for a hand cart is disclosed. The braking system has a split axle which is rotatably connected to the cart frame. Braking components are affixed to each of the split axle sections. An actuator is connected to a caliper system, which caliper system is used to push the braking components together to lock the split axle into a single axle for braking or controlling the cart.

The hand cart defined in claim 1, wherein each brake is a drum brake. 3. The hand cart defined in claim 1, wherein each caliper has a brake pad affixed thereto, the brake pads being positioned to engage the respective brake. 4. The hand cart defined in claim 1, wherein each brake has a brake pad affixed to its inner side, so that the brake pads engage each other when the brake assembly is actuated. 5. The hand cart defined in claim 1, comprising a connecting rod, the connecting rod being mounted on one of the sides of the split axle and being configured and positioned to engage with the other side of the split axle to operably connect the spilt axle sections. 6. The hand cart defined in claim 1, wherein the actuator comprises a handle and a pull bar to actuate the braking assembly. 7. The hand cart defined in claim 1, wherein each section of the split axle is substantially identical in length. 8. An upright hand cart having a frame, a pair of laterally spaced wheels, a load plate and a brake assembly, said brake assembly comprising: a pair of bearing brackets connected to a hand cart in spaced-apart relationship and extending from the hand cart between a pair of laterally spaced wheels;each of the bearing brackets being connected to a caliper;a split axle rotatably mounted between the wheels and being operably connected to the cart, said split axle including a first axle segment connected to a first wheel, and a second axle segment connected to a second wheel;the axle segments being rotatable with respect to each other;each of the axle segments being connected to a corresponding one of a pair of brakes;an actuator mounted on the frame of the hand cart; andthe actuator being operably connected to a pair of calipers; whereineach of the calipers is movable to engage a corresponding one of the brakes to move the brakes together to lock the axle for controlling or stopping the cart. 9. A hand cart having a frame, a pair of laterally spaced wheels and a lifting blade, the lifting blade comprising a flat surface and being designed to lift and support objects to be moved by the hand cart, the cart further comprising a brake assembly, said brake assembly comprising: a pair of bearing brackets connected to a hand cart in spaced-apart relationship and extending from the hand cart between a pair of laterally spaced wheels;each of the bearing brackets being connected to a caliper;a split axle rotatably mounted between the wheels and being operably connected to the cart, said split axle including a first axle segment connected to a first wheel, and a second axle segment connected to a second wheel;the axle segments being rotatable with respect to each other;each of the axle segments being connected to a corresponding one of a pair of brakes;an actuator mounted on the frame of the hand cart; andthe actuator being operably connected to a pair of calipers; whereineach of the calipers is movable to engage a corresponding one of the brakes to move the brakes together to lock the axle for controlling or stopping the cart.
