ABSTRACT:
A trailer (10, 210 or 310) having a tilting bed (26, 226 or 326) is described. The bed has a front portion (26A) and a back portion (26B) which are pivotably mounted together. The front portion is fixably mounted to the frame (12, 212 or 312) of the trailer. The back portion is able to be lowered to form a ramp for loading and unloading the trailer. A cable and pulley system (40, 240 or 340) is used to raise and lower the back portion of the bed. The cable(s) (50, 250, 251 or 350) of the cable and pulley system can be loosened or tightened using either a winch (52) or a hydraulic winch (266 or 366). The pivot point of the back portion is located in front of the axle (16) of the trailer which creates a longer leverage arm which allows for easier lifting of the back portion of the bed.
