Pipe lasers for utility construction
Trimble has introduced the Spectra
Precision® DG613 and DG813 pipe
lasers, a new generation of Dialgrade®
lasers for the installation of gravity flow
pipelines.
The DG613 and DG813 are smaller
in length than their predecessors, the
DG511 and DG711. This shorter length
is a benefit when setting up the units in
manholes with precast inverts and a tight
radius. Both models have a grade range
from -12 to +40 per cent and are fully
self-levelling over the entire grade range.
The cross axis is also fully compensated,
providing quick set up and ensuring
the laser will be level without having
to manually rotate it in the invert. The
new pipe lasers have a 150m (500ft)
working range, providing a single setup
to lay pipe from one manhole to another.
The new RC803 remote control provides
full function control and utilises infrared
communications when in the pipe at a
distance of up to 150m (500ft). For ‘over-
the-top’ setups, the remote uses radio
communications at a distance of up to
130m (430ft).
Flexible power options for the pipe lasers
provide 40 hours of operation with NiMH
rechargeable batteries and 50 hours with
alkaline 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 available. A large LCD allows
users to easily view the display when
the laser is in a manhole. All functions
are controlled via a graphical, user-
friendly menu. The same user interface
is on the RC803 remote control.
Both models incorporate new features.
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 100 per
cent grade in a few seconds and then
adjusted left or right to perform first day
set in a short trench. Both models have a
Line Scan function that allows the user to
quickly align the beam to the pipe laying
target’s centre, which is placed in the last
piece of pipe.
The DG813 has advanced features when
used with the SF803 Spot Finder beam
detector. The Spot Align feature will
automatically align the DG813’s beam
to the centre of the Spot Finder. This
alignment feature can be used for an
accurate and quick setup, to orientate
the beam towards the next manhole
when used in a trench, through the pipe
or when doing an over-the-top setup.
Spot Match is used for checking that the
pipe has been installed to the correct
grade or for finding the grade value of
a pipeline. This can also be used to
calculate the grade between manholes.
SpotLok is used to lock the beam in
a desired position for applications
when the beam could be subject to
environmentally caused drift, such as
temperature changes in the pipe.
