Re-purposed hand trucks - this one has a power strip tie-wrapped to the back, so just ONE extension cord needed - looking at your situation, you might wanna relocate the axle to use bigger wheels (same for me, just haven't got around "tuit" yet); 13" are MUCH better)
piece of 1/8" FB lets MOST side grinders just slip over it and hang. For transport, I just grab the whole bundle of power cords somewhere near the middle and hang it up over the hand truck handle... Steve
BTW, as shown these can be a little tippy - I later put a couple of those rectangular buckets kitty litter used to come in, moved clamps down to those - improves balance noticeably - the OTHER advantage: easy to move those "too portable" goodies back into secure storage when yer done...
