A support apparatus for transporting a load on a hand truck in a safe and balanced manner includes a base which is disposed generally horizontally when the hand truck is employed for transporting such load and a pivot means for pivotally connecting a first end of the base to the axle intermediate the pair of wheels of the hand truck. Two auxiliary wheels are attached to an opposed second end of the base. A frame support is disposed generally vertically when the hand truck is employed for transporting such load and has a first end thereof connected to the base and has a second end thereof abutting the portion of the hand truck. A brace has a first end thereof connected to the base adjacent to and spaced from the first end of the base and has a second end thereof connected to the frame support adjacent to and spaced from the first end thereof.
