Ultra-visible green Spectra pipe laser from Trimble

The new Spectra Precision DG613G pipe laser.

Trimble has introduced a new green Dialgrade laser for the installation of gravity flow pipelines: the Spectra Precision DG613G pipe laser.

The DG613G, with an ultra-visible green beam, has the same compact design and features as the DG613. The laser's short length is ideal when setting up in manholes with precast inverts and a tight radius. Both models have a grade range from -12 to +40 percent and are fully self-leveling over the entire grade range. The cross axis is also compensated providing quick set up and ensuring the laser will be level without having to manually rotate it in the invert.

The DG613G has a 150 meter (500 feet) working range providing a single setup to lay pipe from one manhole to another. The RC803 remote control provides full function control and utilizes infra-red communications when in the pipe at a distance of up to 150 meter (500 feet). For "over-the-top" setups, the remote utilizes radio communications at a distance up to 130 meter (430 feet).

Flexible power options provide 30 hours of operation with NiMH rechargeable batteries. Alkaline batteries can be used directly in the laser without a separate battery pack. To recharge the NiMH batteries, a vehicle outlet 12V charger is also available as an optional accessory.

A large LCD display with a graphical interface allows users to easily view the display when looking down at the laser in a manhole. All functions are controlled via a graphical, user-friendly menu that is replicated on the RC803 remote control.
The DG613G offers features to save time and money. To reduce costly rework, the Line Alert will cause the beam to blink to notify the operator that the setup has been disturbed. Using the Line Set function, the beam can be moved up to 45 degrees/100 percent in less than 10 seconds and then adjusted left or right to perform first day set in a short trench. In addition, it has Line Scan functionality, which allows the laser to be quickly aligned to the center of the target in the pipe.
