is designed to be an allround Dual Grade Laser with
two specific features -ease of use and reliability. The two control panels, one behind each grade direction,
are identical and easy to understand. No more wondering
if you are adjusting the right direction.
The AMA DL has an in-built battery pack with 60 hours
of operation on each 7 hour charge. A charge over the
weekend gives a working week’s operation.
The integrated tilt foot allows for the full -5% to
+20% grade range without extra accessories.
These features make the DL the perfect choice for rental
operation or the professional contractor.
The DL uses the same optics as the AMA AC1 Pipe Laser,
ensuring a strong, visible and perfectly round beam
for 500m radius working range. The rotation speed can
be set up to 1200rpm to give maximum stability for machine
control systems.
We wanted to have a large X grade, -5% to +20%, and
still keep small, well protected windows. The solution
is a second tilted 5/8" thread for X grades between
10% and 20%. No extra accessories needed.
We designed the DL for reliability and longevity. A
shock proof, rubber suspended mechanism is mounted in
a rugged cast aluminium housing.
The DL is designed for a life of 10 years, going right
against the trend in the industry. Each unit is individually
shock tested and temperature calibrated. The windows
are small, thick and recessed to minimize the risk of
breakage.
The DL has two identical displays, one behind each grade
direction. Easy to understand, avoids mistakes. Grade
can be dialed in digit by digit, or just press + for
accelerating grade. The MODE button will let you select
rotation speed.
Exchangeable battery packs are lost or cause problems
with dirt and water getting at connectors. The DL is
powered by an in-built battery with 60 hours capacity
per 7 hour charge. You can easily activate the TILT
function to protect yourself against accidental movement
of the laser setup. The DL will shut off and warn if
hit or if one tripod leg sinks.
TILT is activated on the user configuration menu (press
the MODE button a few seconds). Here you can also switch
between automatic levelling or manual, you can mirror
the Y axis grade for easy grading of both cambers, and
you can lock the keyboard for added protection. The user configuration menu
also contains other useful features: Wind sensitivity
- In windy conditions or heavy ground vibration, you
can make the self levelling less sensitive to allow
you to carry on with the work. You do this by selecting
WIND. You can go the other way by selecting FINE for
extra high precision under very stable conditions.
Sector shutoff - If you are working in a multiple
laser setup, you can shut off sectors of the laser beam
rotation so that the lasers don't interfere. This is
also useful when working close to reflective surfaces.
Select SCT and turn on/shut off any of the 8 sectors.
Alignment scope - As
an option, the DL can be factory equipped with a rifle
style alignment scope for accurate alignment of the
main axis. To enable maximum precision, the DL's main
axis can be field calibrated to the alignment scope
using the SCOPE function.
House - When using the
alignment scope, accuracy is increased if the DL housing
is level. Select HOUSE to give you bubble indicators
in X and Y to help you level the DL housing.
Remote control - Optional The remote control is designed
for three specific tasks:
1. Working the display controls when the DL is mounted
on a high rise tripod. You have full control over all
parameters from the remote.
2. Working the DL from the cab of a machine. You can
mirror the Y grade and shut the laser off.
3. Alignment of the main axis. You can stand with a
detector on a pole 50m from the DL and align the main
axis using the remote control.
Charger in a robust carrying
case. We offer a variety of hand held and machine mounted
detectors. Optional accessories include 12V cable.
