Horizontal hydraulic drilling units are manufactured in the following types:
- MINI-20
- HWP-25
- HWP-27
- HWP-27S
- HWP-33
- HWP-50
- HWP-80
- HWP-120
- HWP-140
Existing network of trafficked roads, railway crossings pose problems in the contruction of non-collision sewer pipelines, gas, heating and cable entries for power and telecommunications.
To avoid the enormous costs and difficulties arising from traditional quarries, we designed and built with modern horizontal hydraulic drills.
Drilling permit for pushing these pipes with diameters ranging from 100 to 1400 mm and a length of 50 m Drill Selection is made according to the diameter and length of the drilled hole.
Drilling permit for pushing these pipes with diameters ranging from 100 to 1400 mm and a length of 50 m Drill Selection is made according to the diameter and length of the drilled hole.
Each rig is supplied from the hydraulic-powered internal combustion engine. It is possible to supply drilling rigs with hydraulic excavators after adaptations.
Rigs are equipped with cutterheads for normal land, and the widia heads for the rocky land.
