Core offering

Rockzone designs and manufactures hydraulic attachments for excavators, including drum cutters (Rockwheel), crusher buckets (Rockcrusher), screening buckets (Rockscreener), and sorting buckets (Rocksorter). The attachments operate using the excavator's hydraulic hammer circuit with only two hydraulic line connections and are compatible with excavators from 1 tonne to 125 tonnes operating weight. The products enable on-site material processing for construction, demolition, mining, quarrying, recycling, civil engineering, and landscaping applications.

Product overview

Rockzone (ROCK.ZONE GmbH) is a German manufacturer of hydraulic attachments for excavators, offering a comprehensive portfolio of heavy equipment tools. The product lineup includes four core product families: Rockwheel (hydraulic drum cutters/milling heads for cutting, trenching, and milling), Rockcrusher (crusher buckets for on-site material crushing), Rockscreener (screener buckets for material classification), and Rocksorter (sorting buckets with patented drive systems). These products share common features including HARDOX reinforcement, planetary gears, and compatibility with standard hydraulic systems. The company also offers specialized sub-products such as the Roadrunner asphalt planers, AX/TC series trenching heads, and Cutter Bucket (CB) series combined cutter-buckets. The portfolio was expanded through acquisition of Hartl-Crusher Engineering&Marketing GmbH. Products are designed for excavators ranging from 1 tonne to 125 tonnes and serve applications including demolition, mining, landscaping, infrastructure, recycling, tunneling, and underwater work.
