Two crank stands only hold a weight capacity of 140 lbs. So, before you can find out how big of a load you can mount on them you must add up the weight of the truss, any truss mounted power packs or dimmers, "y" adapters, nuts and bolts, and don't forget cable and tie weights. Subtract that from 140 lbs and then you'll have the actual lighting weight that can be added. ADJ triangular trussing is very heavy because it isn't aluminum. It actually will consume almost all of the weight capacity with the above mentioned necessary accesories. The crank trusses are most applicable with the black "I" beam truss, because it is light. But it holds 140 lbs as well if evenly distributed. The triangular trussing can handle a much heavier load, its just that the stands cannot. A third solution would be to find a triangular trussing that is made of aluminum and use it with the crank stands. Depending on how much weight you want to hang, your best option may be to go with both heavier stands and strong triangular or square trussing. It pays to do the math before you spend your money. Not much would be worse than having your rig taking a tumble and possibly seriously hurting someone in addition to the financial loss. Besides a ladder really isn't that big of deal to have to use. You'll proball have to use one anyways to focus your lights. Hope this helps.
