发明名称 Modular gantry and structural element therefor
摘要 A structural element (10) which can be used to modify the loading characteristics of a gantry module (18). The element (10) is securable between legs (22) so that for a standardized roof assembly (19) the gantry module (24) constructed using the structural element can span a greater distance with comparable loading characteristics with modules (18) which have a greater number of supporting legs. The structural element (10) has particular application is modifying a standard gantry module (18) into a vehicle access module (24) without compromising loading characteristics.
