Jtec is the leader in Mother/Daughter tugger systems throughout North America. Our CarryMore Tugger Cart System transports Daughter Carts containing up to 4,000 lbs. of materials OFF THE GROUND thanks to its patented Elemate feature. This allows daughter carts to always utilize one or two fixed casters to aid maneuverability with fantastic ergonomic considerations for the operators. Sturdy CarryMore Mother Carts LAST -- as evidenced by original models still being used in factories in America since 2012. And those carts are used 24/7/365 in those sites. Check out this video!
