Straddle Lift Sand Mold Transfer Car


A customer needed a way to move varying sizes of sand molds without damaging them. The molds ranged in size from 36” to 74” cubed and weighing from 3,000 to 22,000 lbs.


The design requirements needed to clamp, lift, transport, lower and unclamp. The base is a four wheel transfer car with two individually driven wheels requiring them to be electrically synchronizing via a variable frequency controller. The clamping/unclamping and lifting/lowering functions are performed using an onboard, self-contained hydraulic power unit.
