The trailer for use in transporting a load from one area to another. The trailer (10) comprises a frame (11) and a bed (20) operatively mounted to the frame (11) which is capable of being moved from a first or lowered position to a second or elevated position in substantially vertical manner or nontilting manner. At least one lifting mechanism (40) is operatively connected to the bed (20), which applies the greatest force for lifting the bed (20) from lowered position to the elevate d position at the beginning of the lift, rather than at an end or midpoint of the lift. A least one over-center latching mechanism (80) secure s the bed to the frame when the bed is in the elevated position.
