Very light, easy to transport and precisely manufactured brackets made from aluminium for installation in sole-plate and stope areas.The repeat accuracy achievable for the positioning of the instrument lies in the range of a few tenths of a millimetre.
As even on large construction projects, it is rare that many instrument positions are used simultaneously, this system is extremely economical.
The arm of the bracket consists of a very stiff 40 x 60mm aluminium box section with a screwed on device mounting plate (Ø 120mm). The tripod is fixed to the bracket using a handy 5/8“ tightening screw.
The bracket is adapted to the wall with this system using a solid brass bolt with a protective cover which is glued to the wall. During measurement, the cover is unscrewed and replaced with an adapter bolt made of stainless steel, the console is slid onto this and fastened using the clamping lever.
The two guide pins on the adapter bolts 14-TK1-AB increase the centring accuracy as the bracket arm can only be in a position (identical to the initial installation in relation to the wall bolts.
Setting up is thereby done in a matter of seconds as there is no requirement for a lengthy horizontal levelling of the bracket.As the tripod only offers limited levelling possibilities, the wall bolts must be very precisely installed. For this, we recommend our two-component cement and the installation apparatus 14-TK1-EV with two installed tube guides at right-angles to each other.
The positive contact of the head of the bolt on the tunnel lining is very important here.Therefore the gap between the back of the bolt and the tunnel lining must also be filled with two-component cement, or similar.
If you plan to use a device heavier than 7kg or a motorised instrument, the console should be secured using two additional braces to the sides and downwards to achieve even higher stiffness.
For this, there are two standard wall bolts with M8 internal thread installed under the bracket on the 11R-series.
The bracing kit 14-TK1-TSA contains all the required parts and is available as an option.
For the protective transport of bracket, adapter bolts and the optionally available bracing kit, we recommend our transport case 14-TK1-TK-S with a foam insert cut to suit. In this special case, you can store two complete bracket sets with bracing sets and installation aid.
Distance to wall: 490mm
Weight (without bracing kit): 2.3kg
