Bidirectional Unimog U500 with eight-spindle screw machine (ASM) 30.75.
Bidirectional Unimog U400 with eight-spindle screw machine (ASM) 30.75.
Both of these precision screw machines at PORR allow perfect results when loosening and tightening the rail mounting. The 8-spindle precision screw unit with a bidirectional unimog as a carrier vehicle enables fully automatic, synchronous loosening and tightening of rail fastenings.
Both the quality (through computer-supported recording of the torques achieved) and the performance is above-average compared with conventional screws.
