I hope this mail finds you well.
For power plant project GGH a roof over the ash silo for rain protection is required. For this please revise your dwg drawing according our attached drawing B-Th-435-8151 Sh1_B. Please consider that the ash conveyor must be supported by roof & wall of ash silo (see isometric view). The load of top of ash conveyor is appr. 5.5 tons.
Thank you in advance.
