Laser grade lasers feature wireless remote control
The Spectra Precision GL412 (single-grade) and GL422 (dual-grade) lasers offer fast, easy horizontal level, grade and vertical plumb setup with no manual levelling. They send a continuous, self-lev-elled 360-degree laser reference over an entire work area, and feature a wide grade range of -10 to +15 percent, so they can be used for a variety of slope applications. These rugged lasers can withstand being dropped up to one metre (3 feet) directly onto concrete.
A two-way, full-function remote control allows the contractor to do everything with the remote control that they can do at the laser keypad, including grade reverse on both axes, up to 100 m (330 feet) away from the laser – even from the cab of the machine. The ability to make grade changes from anywhere on the job greatly reduces setup time and speeds operation, especially when multiple job grade breaks are needed.
Additionally, the GL412 and GL422 self-plumb in the vertical position to accommodate an even wider range of applications, such as anchor bolt installation, plus form, tilt up and curtain wall plumbing. Both units also incorporate automatic temperature and grade compensation providing high accuracy in any weather or geographical location, and no rework.
The laser beam can be turned off on as many as three sides. This capability eliminates interference with other crews on the job site by keeping the beam from straying into other work areas. The lasers can be used with an HR550 Laser Receiver at an operating diameter up to 800 m (2,600 feet), or with the CR600 Laser Receiver mounted on a machine.
General contractor applications include: levelling such as forms, footers and pads; grading and excavating; vertical alignment and plumb for anchor bolt installation, plus form, tilt up and curtain wall plumbing; concrete sections with runoff for sports fields, tennis courts and driveways; steep slope road embankments and ditch banks; and parking garages, ramps and drainage.
