Re: Welding casters to a "shop crane" base

I should have mentioned that I would prefer to bolt them on......... But I have seen various applications welded on.

The only bearings you need to worry about are the swivel ones, they really aren't much of a bearing. Just two stamped plates with a ring depression and some loose ball bearings. If you wrapped the bearing area with a wet towel and welded the plates on with 1" welds using a stick or MIG welder you shouldn't heat them up enough to bother. The main rolling load bearings are held in by a bolt with a zerk on the head end. Just remove.

I'd caution you to not leave a heavy load suspended for any period of time (more than a few days or weeks) You will flat spot the plastic, the rig just won't roll any more. The plastic usually springs back ........ eventually.


Thanks Roy, I will post an update when I get them and weld them
on. Good point on leaving weight suspended, which I do not want to do
for safety reasons also.

Yes, you won't weaken the legs by welding to them - however, you'll trash the bearings in the casters due to the heat. BTDT, got the weld-spattered T-shirt. If the legs aren't wide enough for the caster base, weld a plate onto the legs, then bolt the casters to the plates.
