<p>The vehicle frame members are illustrated at (15 and 16) and as can be seen a box-like sub-frame (18) is fitted, the vehicle having been modified to accommodate the sub-frame (18). The sub-frame (18) is the outer structural frame for the ramp assembly from below. The ramp assembly is 'a drop-in unit' cartridge type unit that is placed into position from above making it a simple matter and easy to insert into the sub-frame (18) of the vehicle. Structural integrity of the vehicle is not interfered with; the frame (18) is designed to ensure structural integrity. The ramp assembly also has a cross-frame member (19) employed between the angles (20 and 21). The angles (20 and 21) simply screw to the frame members (22 and 23) using fasteners. A cover plate (13) is screwed into position and this cover (13) can be simply removed should the mechanics of the retractable ramp assembly which are housed beneath it require service.</p> |
