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.
Claims25
A trailer which comprises:
- (a) a frame having a first end and a second end with side members extending therebetween;
- (b) a tongue assembly mounted on the first end of the frame;
- (c) a single axle having opposed ends and attached to and extending between the side members of the frame spaced apart from the first end of the frame with wheels rotatably mounted on the opposed ends of the axle adjacent the side members of the frame;
- (d) a bed having a first portion and a second portion, each portion having first and second ends, the first portion being mounted at the first end to the first end of the frame and the second end of the first portion being pivotably connected at a connection point to the first end of the second portion wherein the connection point of the first and second portions of the bed is located adjacent the axle between the first end of the frame and the axle;
- and
- (e) pivoting means for pivoting the second portion of the bed from a raised position with the first and second portions of the bed in a same plane to a load position with the second end of the second portion adjacent a ground surface such that the second portion of the bed extends between the ground surface and the second end of the first portion at an angle, the pivoting means including a lifting means mounted on the second end of the frame and connected to the second portion of the bed.
