ABSTRACT:
The dock plate is formed by a plate member having upper and lower surfaces, front and rear ends and two opposites sides. Two side members are provided which are removably attachable to the two sides of the dock plate. A handle with a wheel is attached to each of the side members. The two side members and their handles and wheels may be removed from the dock plate or attached to the two sides or dock plate at different positions along their lengths. When the two side members are attached to the sides of the dock plate, the handles may be pivoted to operative positions for allowing the operator to lift and move the dock plate with its wheels or to out of the way inoperative positions. In another aspect, the two side members each have outwardly extending tabs for supporting their handles when in their inoperative positions.
