Stilts using W-Beams were added to these big ton variable assemblies in order to meet height requirements for an oil refinery in Port Arthur, TX. Entirely fabricated with carbon steel, these big tons measure 50 1/2″ – 70″ L x 18″ – 22″ W by 37″ H and are capable of supporting loads up to 113,734 lb with an upward travel range of .076″ – .816″. Permanent travel stops were later installed in order to prevent any chances of downward shift.
