A 2D machine control system uses laser technology in construction and earthmoving equipment to precisely guide the machinery along two axes: elevation and slope. This system consists of a Spectra Precision GL1425C dual grade laser level that emits a laser beam and an Spectra Precision LR50W Machine Receiver mounted on the construction equipment. The GL1425C projects a reference plane and the LR50W receiver detects the laser beam's position relative to the desired grade or slope. This information is then relayed to RD20 remote display allowing the operator to adjust the machine's movements accordingly to achieve precise grading, leveling, or alignment Overall, this Machine Control System enhances accuracy, efficiency, and consistency in construction tasks, leading to improved productivity and quality of work. Spectra Precision GL1425C Dual Grade Laser The automatic self-leveling Spectra Precision® GL1425C dual grade laser is the most rugged, cost-effective laser that does three jobs—level, grade, and vertical alignment. Even in harsh jobsite conditions, the GL1425C delivers consistently reliable and accurate performance, enabling you to work faster and smarter.
