Kemroc launches drum cutter attachments

Published 24/2, 2020 at 12:01

Kemroc started 2020 by announcing a major expansion to its product range with a complete range of twin head rotary drum cutters. The new models will be available from March 2020 with additional models expected to follow later in the year.

In addition to the standard EK and convertible EKT range of drum cutters with chains, Kemroc has completed its product offering with rotary drum cutters that have no central cutting chain. With strong, torsion and wear resistant housings and very rugged gear drives, these are designed to work in demanding conditions. The KR range of rotary drum cutters are designed for use on excavators from 1t to 125t with a very robust design making them the ideal attachment for use on short arm excavators in tight spaces, making them ideal for tunnelling as well as vibration free and silent demolition of reinforced concrete structures. 

The new drum cutters are compact, lightweight but strong. The direct drive KRD drum cutters are available for use on excavators with operating weights from 20t to 40t and are ideal for use on long arm excavators for demolition and shaft sinking applications. They can also be used for soil stabilisation and concrete renovation applications, with intentionally oversized bearings being used to support the cutter drums for a long operating life.

With these additions to the product range, Kemroc states it has the largest number of rotary drum cutters on the market. For excavators in the 20t to 50t range alone there are three models of different sizes, tailored to the weight and hydraulic capacity of the respective carrier. In addition to the new range of rotary drum cutters, with or without cutter chain, a new KRL range of longitudinal drum cutters for use on excavators with operating weights from 15t to 40t has been introduced. These are designed for use in civil engineering applications such as the cleaning of bored pile heads and excavation of holes for foundations. 

A wide range of cutter options are available, including a conversion pack for grinding tree stumps and can also be easily converted into an auger drive unit with the models available for use on excavators from 2t to 70t operating weight. Compact, robust and easy to maintain, these rotation units expand the operating capabilities of all attachments. 

Klaus Ertmer, the owner and managing director of Kemroc says of the new developments: “All of our machines are designed to be strong enough to withstand the forces they will be subjected to during normal operating conditions. They create low levels of noise and vibration and they are energy efficient. We can guarantee this because we have been involved in rock cutting technology for more than twenty years and we combine our experience with the needs of the customer when we design and build our products. We want to make our range even better and larger. For this purpose we have recently expanded our design department and we will introduce further additions to the product range later this year.”
