Ways of improving the stability of an object

It may be possible to use 'A'frame stiffeners as shown in the sketch. It is a free hand sketch and not to scale.

Thank you, I had an idea to use struts but the customer may not desire them. I will have to try to change his mind.

Make the struts as hyperbolae. Sort of (CE) Designer struts!

Hmmm,thats seems very intregueing, hyperbola struts. I can maybe use hollow sections for the struts. Cost will go up but it is a very attractive idea Ramani. Thanks 👍 If i use this idea i will post a picture of the finished product. Right now i'm trying to source the appropriate castors for the job. Im trying to find ones with a wide base to avoid sinking in the gravel.

50 mm wide rubber casters are available. If necessary two of these can be mounted side by side at each location. That should spread the load well.

Two castors side by side would be great but im looking at cost. All parts are being made od 316 stainless steel (the panel is being used in a plant near the sea). Due to this the cost to the customer is already high. So far i am unable to source castors wider than 2" maximum width.
I am also exploring the option of making the wheels myself to the desired width. I have polyurethane that i can use to cast the wheels but the problem with this is that the polyurethane may deform easily.
I can make the trolley with the 2" castors but im trying to make life easy for my customer, but only if he is willing to pay a little extra of course 😎

You can put a rubber sleeve (replaceable) over an SS tube of suitable diameter and width. Close the ends of the tube with an SS sheet through which the shaft goes. Since there is no requirement for speed or long distance movement, bush bearings would suffice. UHMWHDPE bushes can stand abrasive environment.

This is an option but i dont think my superior will approve it. I think he would rather give in to the cost of buying. the castors.
