World innovation
In addition to standard EK and the convertible EKT range, traditional style rotary drum cutters are now also available from KEMROC. They are designated as the new KR range of drum cutters. Designed to be incredibly robust, these attachments are ideal for use on short arm excavators working in confined spaces, especially in tunneling and also for the vibration free and silent demolition of re-enforced
concrete structures.
Effective dust control is particularly importand in demolition and tunneling applications. The KR range of cutters are designed for the installation of an optional, hydraulically controlled water jet dust control system.
