A set of machinery skates 6 Ton capacity each. Can be used to move heavy objects. Polyurethane rollers allow those skates to roll on less than perfect surface. In the past I used skates like that to move heavy loaded containers on a concrete floor and lighter ones on softer ground using steel plates. Super cheap for what they can move!
