[2][3] At Kalmar production was carried out on 18 ft (5.5 m) battery-driven carriers, which held one single car body at a time.
The carriers were designed to swivel and rotate the individual bodies so that workers could access every aspect of the car in a practical fashion.
The best advantage with those carriers, was that they held car in best possible ergonomic position, and by that reduce the personnel's work related injuries.
While a worker on a conventional assembly line might spend his entire shift mounting one license-plate lamp after another, every member of a Kalmar work team may work at one time or another on all parts of the electrical system—from taillights to turn signals, head lamps, horn, fuse box and part of the electronically controlled fuel injection system.
As long as cars roll out on schedule, workers are free to take coffee breaks when they please or to refresh themselves in comfortable lounges equipped with kitchens and saunas.
