Simple machine skates

(1/4) > >>

PekkaNF:
I need to move 1 metric ton and bit heavier or lighter machines ocassionally.

I build a toe jack probably two years ago, now I got impulse to build a skates.

I decided to build longer kickbike types and lowest practical. I am using truck wheels and UPE beam, I had a about one metre pice ling around, I cut it half. Due height of the beams does not allow wheel to clear the web, it must have a cutout.

Soaked the parts two days in food grade vinegar to remove rust and scale. Then I used rotabroach cutter to drill holes for the wheel axles.

Rest is easier, just needed holes to clear the wheels. I don't have a plasma cutter. I drilled 18 mm holes into corners and used bandsaw to cut the excess and 12 mm mill to clean them up.

I still need to turn spacers both sides of the the wheels and turn grooves for circlips or something to keep the axles from falling off. Fit is bit tighter than sliding fit, it needs securing

Golly Pekka,
      You had me wondering just how big this was going to be. Using truck wheels?  :Doh:

Then I looked at the pics and solved my dilemma.   :lol:
      Here in OZ truck wheels to me would be something like 24" diameter plus tire. 

   Regards,

John I think that they are PALLET truck wheels / rollers

Nice job Pekka  :thumbup:

PekkaNF:
English is my third language....you can blame me.

These things gets me off guard sometimes, specially with terms like tracktor trailer...I am thinkking a trailer behind John Deere or other africultural implement and the other guy might be talking about something more road going vessel.

Andrew is right, I was refering to pallet truck rollers, about 75 mm dia, length about 70 mm.

Follw up plan (one of these winters) is to build "rotating dolly"







Castor wheels or a truck is not easy to carry load, be stable and turn easily. Very tempted to buy a castor wheels ready made, but they seem to pretty expensive for my limited use.

Pekka,

Many moons ago when I worked with designing packaging machine plants we often used this kind of help when having to move heavy machinery:

You can see the swedish name of it in the link but I have no clue to what it is called in english, google translates suggestion "roller skewer" is far off target I think.

Anyways, the rollers on this one are bearings, probably deep groove bearings and it works as shown for 3 metric tonnes. The model I used had a substantial axle and cast iron rollers which is easy to make providing one have the CI bar of course.

So bearings or full metal rollers is my idea for your skates, also for the steerable one.

Just another idea really.
