A heavy vehicle and machinery trailer comprising: (i) a trailer base having a plurality of wheels and suspension means; (ii) a trailer bed supported on the trailer base by the suspension means; (iii) loading ramps connected to the trailer bed wherein the suspension means, or other methods such as hydraulically operated landing legs, are adapted to allow an operator to alter the pitch and/or roll angle of the trailer bed relative to the ground surface and wherein the loading ramps are adapted to have varying lengths such that when they are extended to the ground on a sloped surface, the lengths can be adjusted so that the ramps are evenly pitched. Further, the trailer has a hydraulic system under the control of an electrical controller which is operated by a user either by control panel or remote control. The electrical controller has a preset matrix of safe loading and unloading parameters which it uses to determine whether the sensed state of the trailer is safe for loading or unloading.
