Tribrach Introduction:
A tribrach can come in handy when you need to use an optical or
laser plummet. Plumb bobs can take up valuable time, and they can
hard to use in the wind. Using a tribrach with a laser plummet can
keep it level, but you can also use it with other survey
instruments for the same purpose. Feel free to look at what we have
in stock, so you can find a laser tribrach that’s right for you!
How do you make a tribrach on a tripod?
Mark a point on the floor, precisely level the tribrach, and center
the image in the optical plummet. Draw a pencil line on the tripod
head precisely outlining the tribrach. Rotate the tribrach 120
degrees and fit it to the pencil outline.
Can a tribrach be used with a total station?
You can use a laser tribrach with any type of laser measuring tool,
but you can also use it with a total station or any other surveying
instrument. This device will allow you to attach your instrument to
a tripod, so it can be more stable while you’re using it.
Why does a tribrach need to be adjusted?
The precise alignment of the support area to the base plate of the
instrument assures extremely accurate forced centring. The optical
plummet is so robust that the need for adjustment during the entire
lifetime of the tribrach is practically unnecessary.
How big are the foot Screw on a tribrach?
The hysteresis of Leosurvey tribrachs amounts to a maximum of 3"
(1.0 mgon). The foot screws are maintenance-free and have a larger
diameter.
