Diaphragm wall drilling rig
BAYA TEC System

Baya is the 3rd generation of hydraulic grab and has been tested numerous times in order to improve the drilling rates, which are the best available on the market, today.
It combines the advantage of the pendular grab (versatility) with the Kelly system (performance and quality).

Use
Baya can be used to construct diaphragm walls or prefabricated walls, cut off diaphragm, oblong piles etc… Baya drills up to great depths, into a large range of grounds (silt to strong sandstone with Rc 100 bar). Clients use Baya where they used hydromill before.

Versatility
Its erection is quick, and so is its dismounting with its cardan system and its quick transport kit, which allows carrying the boom elements at the same time.
Baya has a large range of drilling widths from 19.7’’ to 59’’ and a large range of drilling lengths from 106.3’’ to 165.4’’, thanks to the fast interchangeable elements.

Performance
Thanks to its penetration coefficient and its closing force, Baya’s energy is the most powerful in the world, and allows drilling into harder grounds or drilling more quickly.
Thanks to its Kelly and motorised turning joint, Baya can go into the drilling trench very quickly or can empty its bucket above a truck very easily. Finally, the automatic half turn allows better verticality. Baya’s clamshells are all equipped with one chisel allowing better penetration into hard grounds.

Safety
The assembling systems of the different elements are simple and quick, assuring work with safety.
