<p>A modular ramp, in particular for use as a loading ramp or walkway, comprises a plurality of ramp modules 1, each ramp module comprising a ramp frame having a pair of opposing frame end members and a pair of opposing frame side members 2 interconnecting said opposing end members. Each ramp module further comprises a first support leg 3 mountable on a first side member of the ramp frame and towards one end thereof and a second support leg 3 mountable on a second side member of the ramp frame and towards the same end thereof. The support legs are secured to the ramp frame by an adjustable mount 4, the adjustable mount being positioned at a desired elevation along the length of the respective leg. Each ramp frame has means for connection to an adjacent ramp frame. The adjustable mount allows the ramp frame to be selectively mounted on each of the support legs at one of a plurality of inclinations. The adjustable mount can comprise a bracket A1 with holes for a nut and bolt A4, A5 and locking pins A2, A3 that can be adjustably positioned in a side frame central and surrounding circle of holes, respectively. Variations on this theme are also described (Fig 6-10). Preferably, a sleeve L2 & pin L5 allow height adjustment. A hand rail HR2, HR3 can be provided. Double width ramps (Fig 11) or ramps without reinforcing (Fig 12) are also described.</p> |
