Abstract

A system for ice removal and prevention of ice accumulation on semi-trailers and intermodal shipping container chassis systems includes a power supply, a semi-trailer having at least one surface; a plurality of heating elements mounted and spaced apart at regular intervals from one another on at least one surface of the semi-trailer, at least one temperature sensor, a temperature controller having at least one processor and memory having computer executable instructions which cause the system to allow a user to program a desired temperature of a surface of a semi-trailer; sense a temperature of a surface of the semi-trailer; heat the semi-trailer surface with the plurality of heating elements; and maintain a desired temperature of the a surface of the semi-trailer. The system may further include a plurality of heating elements attached to the frames of twist-locks for intermodal chassis systems.

Claims (18)

1. A semi-trailer and intermodal chassis de-icing system, the system comprising:

a power supply;

a semi-trailer having at least one surface;

a plurality of heating elements mounted to, and spaced apart at regular intervals from one another, the at least one surface of the said semi-trailer;

at least one temperature sensor; and a temperature controller unit; including

at least one processor and memory having computer executable instructions which, when executed by the at least one processor, cause the system to:

allow a user to program a desired temperature of the semi-trailer having at least one surface;

sense a temperature of the semi-trailer; heat the at least one semi-trailer surface with the said plurality of heating elements spaced apart at regular intervals from one another, and

maintain the said desired temperature of the at least one surface of the semi-trailer;

wherein the semi-trailer and intermodal chassis de-icing system having at least one surface is a flatbed intermodal trailer having a plurality of twist-locks for container chassis trailers said plurality of twist-locks for container chassis trailers having heating elements mounted to at least one surface of said twist-locks for container chassis trailers.

2. The system of claim 1 wherein the power supply is an auxiliary power unit mounted to a semi-truck.

3. The system of claim 1 wherein the power supply is a commercial generator.

4. The system of claim 1 wherein the power supply is a standard 110-volt power outlet.

5. The system of claim 1 wherein the heating elements have a thickness of less than 2 millimeters.

6. The system of claim 1 wherein the plurality of heating elements are a wire-wound style.

7. The system of claim 1 wherein the plurality of heating elements are an etched foil style.

8. The system of claim 1 wherein the at least one surface of the semi-trailer having at least one surface is a roof of a semi-trailer.

9. The system of claim 1 wherein the at least one surface of the semi-trailer having at least one surface is the underside of a semi-trailer.
