The conveyor designer also depict cable place / space, in consultation with electrical engineer. He also decides trestle type / location in consultation with structural engineer. The belt conveyor designer (mechanical) decides the conveyor arrangement basic drg including space around it, super structure dimensional feature in context of operation, maintenance, etc. The conveyor super structure has following 3 functions:
The over-head belt conveyor as stated above is supported by super structure. I think, the above back ground information will possibly be of use for the structural designers and others to put forward their technical or non-technical queries in the forum and make this topic lively.Īuthor of Book : Engineering Science And Application Design For Belt Conveyors (new print November, 2012)Īuthor of Book : Belt Feeder Design And Hopper Bin SiloĪdvisor / Consultant for Bulk Material Handling System & Issues. The above narration mentions straight line interaction between mechanical, structural, electrical and civil, but in reality it is to and fro, as an ongoing process during initial phase of project implementation. The structural dept creates structural arrangement drgs and manufacturing drgs in conformity with agreed specification, and applicable standards and to provide sound supporting structure for the conveyor. Similarly, comment from electrical engineer and civil engineer is also taken care in basic arrangement drg. After completing the structural design, the designer informs to the mechanical designer, the rectification necessary in the conveyor arrangement drg made earlier (mechanical), which becomes an agreed basic drg by all concerned. The structural designer designs the structure, as per the well known and established design procedure, taking care of the equipment load, wind load, earth-quake, erection load, applicable statutory codes and standards in the country of installation, etc. Thus now structural designer has conveyor basic drg showing conveyor and super structure and also the load applied by conveyor, on to super structure. The conveyor designer also inform live load on floor / walkway depending upon the conveyor components heaviness, etc. Mostly this will constitute compressive or tensile load. Mostly this will constitute shear force at footing interface. Horizontal force - Y along conveyor width. Horizontal force - X along conveyor length, toward head or tail. The loads / forces at each footing comprise of: He also informs the stage - 1 design output and conveyor’s important technical features along with the basic drawing. The conveyor designer inform load / forces acting at all footings of conveyor frame. Then this basic drg copy goes to structural engineer, electrical engineer and civil engineer.
for regular operation, inspection and maintenance of conveyor. as applicable).ģ) Provide access, floor, etc.
The conveyor super structure has following 3 functions:Ģ) Protect conveyor from environment (sunlight, rain, stormy wind, snow, etc. The belt conveyor as stated above is supported by super structure.
Thus, name belt conveyor includes belt, pulleys, idlers, scrapers, drive unit, stringer, stands, head terminal, tail terminal, bend pulley support, take-up, skirt board, discharge end hood, spout, etc. This supporting frame is called ‘conveyor frame’ (say chassis). The belt conveyor is mechanical equipment, and it includes all mechanical, including supporting frame for mechanical items. The belt conveyor when over-head, is installed on / in super structure (gantry, gallery, trestles, transfer houses).
