eiengineering correct ripper use

Our high-performance Single Tyne Ripper is built for precision and power.

Rippers are often used for ripping hard ground, rocks, shale, hard clay and permafrost and any ground condition where normal bucket penetration is difficult.

The ripper shape is an important part of the ripper design, it needs to have a gradual curve so that the material may slide up from the tooth onto the shank where maximum power may be applied, but most manufacturers and operators do not understand the geometry behind ripping the ground efficiently.

The earth is built up of millions of layers over many millions of years and over millions of varying ground and weather conditions.

Excavator rippers are designed to run underneath but parallel with the ground surface to rip rocks and de-layer the ground surface, peeling it back like the skin of an orange.

The best way to penetrate and remove this material is to peel the material away through the “grain” or layers, much like the grain of timber. The ripper tooth should be drawn through the ground parallel with the surface, as shown in the first animation, not as shown in the second drawing which offers greater resistance to the ripper going through the ground with even more resistance onto the tooth, so that the tooth takes the full force of any rocks or stumps that it hits. More importantly, this creates greater resistance which, of course, slows the progress of the excavator which means time and money, and the possibility of breaking of the ripper tooth or even the welded nose of the tooth.

It is only through improper use that ripper teeth break. The tooth is only the device to get the ripper shank to enter the material being ripped or push through or behind the rocks or ice then slide them up the shank where intense force can be applied. Ripper teeth should not be used to pry rocks or ice.

In the animation, you can see that the ripper slices through and slides material up the ripper shank.

So, ideal ripping would entail the ripper being placed at an angle at full reach of the excavator, then drawn through the earth all the way toward the excavator, as close as possible at whatever depth is required, but running parallel with the surface.

Manufactured from eie80 high strength steel and a heavy-duty top box

This guarantees efficiency and reduces wear.

  • As Standard – The Ripper cheeks come reinforced, along with boot, nose and bucket pins that are supplied as standard additions with every Single Tyne Ripper.
  • Armoured Guards – Ripper blade shin guards are available to armour the Ripper against the most unmerciful terrains, and is demanded during abrasive and rock applications.
