Equipment originally came with standard oak crate on shipping pallet. Machine dry weight exceeds 550 lbs. Bench needs to support this weight. Secondary use of bench comes when machine needs to be shipped or moved to another location. Bench is flipped upside down to place machine inside of cradle, strapped into place and hoisted into truck bed. Heavy duty casters on both top and bottom allow for ease of use and storage while machine is on bench or inside crate.
