Rock Splitters<\/h2>\n[\/vc_column_text][vc_column_text css=””]The Rock Splitter is our efficient add-on solution for safe and highly productive rock splitting – the alternative to explosives and demolition hammers.<\/p>\n

Hydraulic rock splitting cylinders allow controlled and cost-effective operations!
\nFor use in urban and sensitive areas, noise, vibration and flying-stone risks must be assessed for the selected setup and compared with a defined alternative under equivalent conditions.<\/p>\n

Thanks to the rugged booster system made by Darda, these have an extreme splitting force regardless of the input pressure of the carrier – whether hydraulic excavator, demolition robot or carrier with telescopic arm and swivel joint – despite their slim design and low weight.<\/p>\n

The rock is not pulverized by the splitting technique. The material remains intact and the production of larger split pieces is guaranteed with more volume per drillhole under safe conditions.<\/p>\n

The splitting step itself does not require process water; water may still be required for drilling or other site operations. Effects on parallel work must be assessed for the site. Even operation under water is possible. The patented automatic wedge lubrication and shut-off device are designed to support component service life; actual service life and cost effects depend on operating conditions and maintenance. This significantly increases productivity in industries such as mining, quarrying, tunneling, construction and demolition.<\/p>\n

With two attachment versions and two different splitting inserts, matched to the prevailing material, we have the perfect solution for every operating condition.[\/vc_column_text][\/vc_column]\n\t\t\t\t<\/div>\n\n\t\t\t\t\n\t\t\t\t\n\t\t\t\n\t\t\t\n\t\t<\/section>\n\n\t\t\t\t

\nSplitters<\/h2>\n[\/vc_column_text][vc_column_text]Conventional mechanical methods destroy the structure of the material by external forces. However, rock and concrete, can withstand very large compressive forces from the outside. By comparison, resistance towards forces acting from the inside out is relatively low. This fact was the basis for the development of the Darda hand-held Rock and Concrete Splitter in 1967 by Helmut Darda. Finally, the development of the Darda machine-guided Rock Splitter also benefited from the enormous experience.[\/vc_column_text][\/vc_column][vc_column width=”2\/3″ vc_columns_pull=”ls-col-md-pull-4″][ls_vc_html5_video vc_file_mp4=”10254″ vc_html5video_controls=”yes” vc_html5video_playsinline=”yes” vc_html5video_loop=”yes” vc_html5video_muted=”yes” vc_html5video_autoplay=”yes” vc_html5video_download=”yes”][\/vc_column]\n\t\t\t\t<\/div>\n\n\t\t\t\t\n\t\t\t\t\n\t\t\t\n\t\t\t\n\t\t<\/section>\n\n\t\t\t\t

Safe Wedge
\nPrinciple<\/h2>\n[\/vc_column_text][vc_column_text]First, a hole of the appropriate depth and diameter is drilled, into which the splitting insert of the Rock Splitter is then inserted and adjusted to set the splitting direction. With hydraulic pressure, the wedge pushes itself between the two counter wedges and presses them apart. The effective splitting force of up to 1800 tons or 17652 kN destroys the structure of rock and stone from the inside. A split is created in a matter of seconds.[\/vc_column_text][\/vc_column][vc_column width=”2\/3″]\t\t
