Rippers
Rippers deliver high efficiency in hard-ground, frozen-soil and rock ripping. They provide a powerful solution in excavation, mining and foundation work.
HKM rippers combine powerful breaking performance with outstanding durability for the toughest ground work. Built from wear-resistant steel bodies and high-strength alloy shafts, the RP20-RP50 models offer long life and corrosion resistance.
Bolt-on toothed picks can be changed in minutes, and reinforced mounting brackets resist bending even under heavy loads. From compacted soils and frozen ground to soft rock masses and loose geological material, they keep maintenance to a minimum while maximizing operator productivity.

This tool performs a pre-selection based on catalogue values and is not a binding quotation. Attachments without a hydraulic supply, such as rippers, have no flow or pressure rows; those models are unaffected by the flow filter. The final choice is made together, based on material, workload and the hydraulic equipment of the carrier.

Frequently Asked Questions
What does a ripper do?
It provides high breakout force to rip hard ground, rock and frozen soil; used in earthmoving and mining.
When is a ripper preferred over a breaker?
In layered, cracked ground a ripper digs fast; in very hard, massive rock a breaker is preferred.
Which carrier does it suit?
The right ripper class is chosen by carrier tonnage. Share your machine and we will recommend the model.
