BACKSpectra Precision GL612/GL622

Spectra Precision the GL612 is a single grade laser and the GL622 is a dual grade laser. Both are rugged, automatic self-leveling lasers featuring grade capability of ± 25% and can be used in a wide variety of grading, excavating and alignment applications by general and specialty contractors. Both grade lasers include the RC602 full-function radio remote control which offers advanced automatic features like Grade Match, PlaneLok and Automatic Axis Alignment. The remote as well as the transmitters have an intuitive graphic display which is back-lit for ease of viewing. Contractors can do everything with the remote control that they can do at the laser keypad, up to 100 meters (330 feet) away—even from the cab of a machine. The ability to make grade changes remotely can significantly reduce setup time and speed operations.

 

Features and Benefits

  • Automatic electronic self-leveling provides fast, easy horizontal level, grade, and vertical plumb setup
  • Large compensated grade range from -25% to +25%
  • Quick setups with the radio remote control for horizontal, vertical and grade applications
  • Electronic Leveling Vibration Filter dampens vibrations typically experienced on tall tripods, in high winds, or on high vibration jobsites.
  • No rework due to automatic temperature and grade- and cross axis compensation
  • Automatic Axis Alignment doing precise automatic axes alignments to a desired alignment points without positioning the receivers 90° perpendicular (+/-40° alignment range on Y- and X-axis)
  • Automatic Grade Match (Y- or X-axis separate) measures and displays the existing grade over unknown ground and eliminates time consuming and error prone calculations, time spent searching for grade plans, and over excavating (X- only GL622)
  • Automatic PlaneLok (Y- or X-axis) automatically locks on to an existing elevation or vertical alignment point which eliminates all drift or possibility of error due to improper calibration or weather (X- only GL622)
  • Very rugged, survives a 1 m (3 ft) drop on concrete—reduces service and repair costs
  • Mask mode eliminates interference with other crews on the jobsite
  • Different rotation speeds (continuously adjustable) plus Scanning Mode offer additional value and make sure also requirements of Interior jobsite will be fulfilled (only GL622)

 

Applications

  • General construction leveling such as forms, footers and pads
  • Precision placement of concrete for critical specification surfaces over long distance and with laser controlled screeds (Automatic PlaneLok)
  • Drift free general construction vertical alignment and plumb for anchor bolt installation, plus form, tilt up and curtain wall plumbing (Automatic PlaneLok)
  • General construction grading and excavating
  • Steep slope road embankments and ditch banks
  • Sports fields, driveways, ramps and drainage
