Shock Absorber
- Effectively absorbs reverse impact forces generated by the DTH hammer, protecting the drill rig power head, especially critical in large-diameter drilling applications.
- Available in two structural designs: Threaded type for water well drilling, oil & gas, shale gas, and geothermal applications; Hexagonal type primarily used in large-diameter foundation piling projects.
- Compatible with DTH drilling rigs, water well rigs, piling rigs, rotary drilling rigs, and related equipment.
| Model | Max. buffer stroke, mm | Elastic component | Connection thread | Dimensions (Ø x L), mm | Weight, kg |
| 6'' absorber | 25 | PU washer | API 3 1/2'' REG | 182 x 565 | 100 |
| 12'' absorber | 75 | Disc spring | API 6 5/8'' REG | 273 x 885 | 300 |
| 18'' absorber | 125 | Disc spring | Hexagonal 273 | 278 x 1400 | 345 |
Tube drawing Bench
