Open Gantry Type Belt Conveyor:
This structure is used where excessive spans between trestle supports make the general conveyors inefficient and in the case of high lift conveyors, (> 30m lift), where serviceability, (safety), becomes a major consideration. As with the general conveyors it cannot be considered to be an environmental friendly structure again being susceptible to wind, rain and spillage from both the trough and return strands.
