L-742 Ultra-Precision Dual-Scan® Roll Alignment System Aligning Parallelism of Rolls Has Never Been Faster HAMAR LASER ALIGN WITH THE BEST

Roll parallelism accuracy of .000045 in/ft (0.0038 mm/m) Up to 70% faster than competitive systems Auto rotating laser planes 200’ (30.5 m) measuring range Longer range, fewer setups Multiple wireless targets reduces manpower Very easy to use with minimal training requirements Real-time data displays for measuring and aligning Today’s alignment lasers are better, faster and more accurate than any other method for aligning rolls and there is no better laser than our L-742 Ultra-Precision Dual-Scan® Roll Alignment System. The system is so easy to use and accurate that you can get...

Measure More Rolls With Each Setup By using a laser plane, the L-742 has the ability to measure multiple rolls from the same setup. Rolls up to 100 feet (30.5 m) above the laser can easily be measured! Read9 Multi-Target Display Speeds up Laser Transfer The setup process is easy and fast because our Read9 PDA Display program displays up to 5 wireless targets simultaneously, so when using the Laser Transfer Method, you simply look at the data for the 2 reference targets (usually #2 & #3) and adjust the laser until both numbers are the same. Then use the measuring target to measure the...

* Gyroscopes not available for purchase. Service only, ** European systems do not calibrate Penta Prism centering, a source of large errors. HLI's Laser Transfer Method Competitor's Pentaprism Method Competitor Beam-Bending Roll Alignment Systems When using the Pentaprism Method with a reference roll, after the Pentaprism is moved to another location along the machine, the laser beam at the second location will not be parallel to the laser at the reference roll by up to ,0005 in/ft (0,040 mm/m), Not very good for 3-7 meter rolls! Furthermore, rotating the prism to reach and upper or lower...

How L-742 Works for Roll Alignment Here’s how the process works for using a reference roll as the laser datum to measure rolls for parallelism to the reference roll. L-742 mounted on L-106 with Target #1 about to be aligned to the reference roll 2. A-1519-2.4ZB Target #1 is placed on the reference roll horizontally at the closest point to laser, is leveled and zeroed in Read9 PDA software. Target #1 is then moved to the far end of the roll. Offset Centerline Reference Roll Datum 8. Then the yaw adjustment on the laser base is adjusted to tilt LP#2 until both Target #2 & #3 show the same...
