In the early 1980s, the construction laser was established on the Swedish market. The construction laser with its rotating 360-degree horizontal laser plane was revolutionary. Now one person could do the height balancing himself, instead of two people with an optical balancing instrument as before.
The accuracy was sufficient for most excavation and construction jobs, and the construction laser also provided a continuous laser plane that made it possible to make real-time measurements, instead of, for example, looking between fluctuations, or via measurement instruments.
The laser market expanded rapidly during the 80's and early 90's, Sweden was one of the most laser-dense countries in the world.
What remained were all the necessary manual elevation calculations to translate the heights of the design and drawings into reality, and then all the extra manual calculations for various superstructures and other elevations to be calculated.
With Z-FIX, almost anyone could (finally) transfer the heights from design to reality without risk of miscalculating. No more manual calculations.
Z-FIX consists of a 2.21 meter long "Z-FIX Main Rod" and a "Z-FIX Computer Head" which you move vertically on the main pole. On the mounting plate of the computer head, you screw your laser receiver. You then calibrate the Z-FIX against a known fixed height and the laser plane. When the fixed height is programmed, Z-FIX calculates the heights.
Set the Z-FIX to a fixed height, i.e. a specific height above sea level.
Move the Z-FIX Computer Head with the laser receiver until the laser receiver is leveled with the laser and signals you.
Lock the computer head.
Program the fixed height 71.78 meters above sea level into the computer head.
When the fixed height is programmed, Z-FIX is ready for use.
Now the display always shows the height above sea level that you have at the bottom of the rod (when the laser receiver is at the right level with the laser and giving a signal).
Set the height for "Finished Floor", at 72.23 meters above sea level.
Move the Z-FIX Computer Head...
...until the desired height 72.23 is shown in the display.
Lock the computer head in place on the rod.
Lift the rod.
When the laser receiver gives a signal, you have the desired height of 72.23 meters above sea level, at the bottom of the pole.
Being able to bring out the heights at the bottom of the pole, in such a safe and simple way as Z-FIX offers, is of course very rewarding. But often after that you want to "add" for the possible superstructure.
For example, it could be the case that the height refers to a finished floor and that you want to excavate 35 cm below that.
This is easily solved with the built-in telescopic rod of 200 cm, which can be pulled out downwards depending on how much you want to lie below the selected height. Superb!
If instead you are excavating for a flat surface, road, green area etc. with different heights, but with the same superstructure, you simply let the extended telescopic rod remain at the same extended dimensions that you wish to be below the finished height and only adjust the Z -FIX computer head to the different heights on a finished surface. Simple and flexible!
On the back of the telescopic rod there is something called a red sectioning scale, which is used for sectioning with large height differences.
Z-FIX has 2 different programs:
Z-FIX Height measurement program, where the heights are displayed, and a Zero scale program.
The zero scale program works alongside the height measurement program and offers the ability to zero any height.
You can, for example, measure how much is to be excavated or filled in relation to the selected height that you set to zero.
Or you use the zeroing function simply to balance differences between different points.
