Conveyor steel work design is governed by the same rules as any other structure. Find out what local Standards apply. You will need to determine the wind load conditions for your site if it is not covered by the structural Standard.

Three supports along a 15m x 800mm conveyor seems excessive unless you have a formidable drop height. ■

The base of these supports are not grouted, and the height of head end support is around 7.5 meters.

Can anybody please tell me what should be the base dimension so that the conveyor does not topple.

Also is there any standards for height to width ratio for these supports.

Greetings and salutations Saini Punjeet,

As louis has said any local codes and wind loads apply.

Would you tell us a bit more please? is the conveyor going to be-

A cable supported belt with a mid belt drive or a steel supported belt with a head pulley drive?

Conveyor belts are typically anchored to bed rock or foundations with mechanical

bolts and or turnbuckles to maintain center lines.

A steel supported belt or cable supported belt will have belt stands that are

adjustable vertically to allow clearance of the bottom belt as it approaches inclines.

The belts supports are as wide wide as the troughing idlers mounting edges to do three jobs,

supprt and carry the belt line and ore weight, maintain the alignment of the belt conveyor.

The belt stands carry the weight of the return idlers and bottom belt and you may

have cable supported return idlers as well in some cases.

The cable supported belt will have sailboats anchored to the ground to maintain wire rope tension with turn buckles to hold the belt up.

Where is the belt tensioner/take up unit/counter weight? or is it to be a screw tensioner at the tail end?

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

The wind load will affect the conveyor as it provides a huge surface area with the belting like a sail and if the wind is strong enough and the belt is not anchored it will be pulled over. Belt wrecks are a messy business especially with long inclines

=========================================================

It may be much simpler to purchase a small mobile steel supported conveyor for this application from Mr. George Baker at ASSINK Inc. or from Dos Santos International or Mr Nordell at Conveyor Dynamics Inc., as all the designing will have been done for you and you will be money ahead in the work with zero aggravation.

If you purchase a stationary steel supported conveyor from one of the gentlemen I have mentioned above the ground work that will be needed for this will only be the design and building of the proper foundation and support piers for it as required by the ground conditions encountered.............

Dear Mr.SainiPuneet,

What is the material you are going to convey? I feel 18 degrees is too high. Are you going to install simple flat conveyor or chevron conveyor or bucket conveyor?

If you don't know I will start a subject myself.

Kind Regards,

You should contact www.cattron.com and www.MSHA.gov to see if wireless remotes are even allowed.

Here is a typical covert request for free design input. You asked for guidance on the stability of what could be reasonably assumed to be a fixed structure. Now it develops into a skid mounted arrangement with an inlet chute some 8m tall. What next. For my money, you're on your own. ■
