Bulk material bed

A bulk material carrier, comprising:

• an elongated bed including parallel elongated side walls joined on opposite ends by front and rear end walls and a bottom wall joining lower edges of the side and end walls;
• support means adjacent the front and rear end walls for moveably holding the bed above the ground surface;
• top rails extending along the elongated side walls from the front end to the rear end of the bed;
• first diagonal truss members, each affixed at a top end thereof to a top rail above the support means at the front wall and extending downwardly and rearwardly therefrom to bottom ends situated intermediate the bed ends and elevationally below the bottom wall;
• second diagonal truss members, each affixed at a top end thereof to a top rail above the moveable support means at the rear wall and extending downwardly and forwardly to a bottom end situated intermediate the bed ends and elevationally below the bottom wall;
• structural means rigidly interconnecting the bottom ends of the first and second truss members.

A bulk material trailer, comprising:

• an elongated bed formed of parallel elongated side walls joined on opposite ends by front and rear end walls and a bottom wall joining lower edges of the side and end walls;
• a wheeled carriage moveably supporting the bed adjacent the rear end walls;
• a hitch member located adjacent the front end wall, adapted to connect the trailer to a towing vehicle;
• an exterior skeletal frame at the front and rear ends forming support columns above the wheeled carriage and hitch member;
• elongated rigid top rails extending along the side walls from the support columns at the front end to the support columns at the rear end wall;
• first rigid diagonal truss members, each affixed at a top end thereof to a top rail and skeletal frame above the hitch member and extending downwardly and rearwardly therefrom to bottom ends situated intermediate the front and rear ends and elevationally below the bottom wall;
• second rigid diagonal truss members, each affixed at a top end thereof to a top rail and skeletal frame above the wheeled carriage and extending downwardly and forwardly therefrom to a bottom end situated intermediate the bed ends and elevationally below the bottom wall;
• wherein the first and second truss members and associated top rails are oriented in parallel vertical planes on opposite side walls of the bed;
• structural means rigidly interconnecting the bottom ends of the truss members elevationally below the bottom wall of the bed;
• and
• an upright rigid web member for each top rail, each extending vertically from a top rail to the structural means.
