With the introduction of vibration technology, in which PRINZING was pioneering involved, the production of precast concrete parts could be rationalized. This was also the starting signal for the industrial production of precast concrete parts in large quantities of much good quality.
One of PRINZING's developments, the patented central vibrator, resulted in the worldwide export of machines for the production of pipes and cable stones in the 50's. At this time the first manhole machine was developed, which was chain driven and electrically operated.
By 1970 it was possible to increase the output of the manhole machines and the quality of the products considerably, due to the introduction of hydraulics.
Also at this time the moveable tilting table machine ("egg-layer") for the continued and efficient production of kerbstones and U-channels, together with bricks was successfully marketed.
