FAQ
- Can the GL612N-14 be used for both horizontal leveling and grading applications?
- Yes, the GL612N-14 operates in both level mode for horizontal reference planes and grade mode for single-axis slopes up to ±10%. You can switch between modes using the RC602N remote control, making it versatile for different jobsite requirements including building pad leveling and drainage installations.
- How does the CR700 receiver communicate grade information to the equipment operator?
- The CR700 features bright LED indicators and can integrate with machine control displays in the equipment cab. It provides visual on-grade/off-grade signals that guide operators in real-time, and can also connect to automatic blade control systems on compatible machines for hands-free grading precision.
- What is the effective working range in typical construction site conditions?
- Under normal daylight conditions, the GL612N-14 with CR700 receiver provides reliable operation up to 1,300 feet diameter (650-foot radius). Range may be reduced in extremely bright sunlight or extended in overcast conditions. For maximum range, ensure the receiver mast is positioned at an appropriate height to maintain line-of-sight with the laser beam.
- Is this system suitable for use on multiple pieces of equipment on the same site?
- Absolutely. A single GL612N-14 transmitter can serve multiple machines equipped with CR700 receivers simultaneously. Each machine operates independently from the same laser plane, making it cost-effective for contractors running several grading machines on large projects. Additional receivers are sold separately.
