No: 12/252906 Application Filed: October 16, 2008 Assignees: CHM Industries, Inc. (Saginaw, TX, US) Claim: 1. A high mast lighting system, comprising: a mast; a pole plate disposed within the mast; and a winch assembly housed within the mast and coupled to the pole plate, the winch assembly comprising a circuit breaker box, wherein at least a portion of the circuit breaker box is disposed through an opening in the pole plate. Claim: 2. The mast lighting system of claim 1 , wherein the winch assembly comprises a spool for winding and unwinding a winch cable, wherein the winch cable is spaced apart from the circuit breaker box at least three (3) inches. Claim: 3. The mast lighting system of claim 1 , wherein the winch assembly comprises a winch plate coupled to the pole plate. Claim: 4. The mast lighting system of claim 1 , wherein the winch assembly comprises a winch plate directly coupled to the breaker box. Claim: 5. A mast lighting system, comprising: a mast; a pole plate disposed within the mast, the pole plate having a first surface and an opposed second surface; and a winch assembly housed within the mast and coupled to the pole plate first surface, wherein the winch assembly comprises a breaker box coupled thereto and extending through an opening of the pole plate so as to extend beyond the pole plate second surface. Claim: 6. The mast lighting system of claim 5 , wherein the winch assembly comprises a winch plate coupled to the pole plate. Claim: 7. The mast lighting system of claim 5 , wherein the winch assembly comprises a winch plate directly coupled to the breaker box. Claim: 8. A method of manufacturing a high mast lighting system, comprising: providing a winch assembly having a breaker box and securing the breaker box to a winch plate; securing the winch assembly to a pole plate disposed within a mast such that the winch assembly is housed within the mast, and at least a portion of the winch assembly is inserted within an opening on the pole plate. Claim: 9. The method of claim 8 , further comprising securing the winch plate to the pole plate. Claim: 10. A high mast lighting system, comprising: a mast; a pole plate disposed within the mast; a winch assembly housed within the mast, the winch assembly comprising a winch plate, a circuit breaker box and a drive system coupled to a winch plate, the drive system disposed at least partially in front of the circuit breaker box; and wherein the pole plate comprises an opening to enable the circuit breaker box to extend at least partially therethough when the winch plate is coupled to the pole plate such that the circuit breaker box is spaced apart from the drive system to provide access to the circuit breaker box. Claim: 11. The high mast lighting system of claim 10 , wherein the drive system comprises a winch cable disposed in front of the circuit breaker box, the circuit breaker box positioned within the pole plate opening such that the breaker box is spaced apart from the winch cable a length equal or greater than the width of a cover on the breaker box. Claim: 12. The high mast lighting system of claim 10 , wherein the drive system comprises an electric motor.
