Erkat Remains a Byword for Quality & Forward Thinking in '19

Published: 19/3, 2019

Erkat has been renowned within the industry for its robust, high-quality special cutter attachments for almost 20 years. Now integrated into Epiroc, Erkat is looking to expand upon its leading position once again in 2019. Among the initiatives is a sustainable solution to the problem of fine dust pollution on construction sites. 

This effort has already produced an innovative dust extraction system for rotary drum cutters. ErkatÕs solution sprays water onto the drum cutter, which can also be retrofitted. The water spray is applied directly to the cutting head or milling area, with the water supplied via an Erkat pump system. This future-oriented system is already being used successfully with the transverse cutting heads of the ER 100 to 3000 models. 

For indoor use where water spraying is not possible, Erkat also offers small drum cutter models with a dust exhaust hood for dry dust collection. This system ensures maximum dust extraction precisely where the dust is produced, and can be mounted to conventional extraction systems. 

Erkat is also working on other systems with differing numbers of water nozzles and is producing special modules for specific working conditions. In the cutting head flushing system, for example, the water nozzles are integrated into the rotating cutting head and the water supply is fed via the gear box. Water spraying takes place within the very area in which the bit will be applied. 

This innovative system will complement the inherent versatility of Erkat drug cutters, all of which feature a robust design, high load-bearing capacity, low maintenance requirements, easy handling and, most importantly, real cost-effectiveness for duct and tunnel construction, special civil engineering, demolition, trenching, and soil mixing applications. And despite its robust design, ER series drum cutters are amazingly low in vibrations, making it possible to work quietly. 

A key feature of Erkat drum cutters is the one-sided mounting of the cutting wheel on opposite from the motor, allowing cutting with a very small side clearance directly against walls or side obstacles. This is ensured by a standard intermediate bracket that allows the cutter to be turned manually in 22.5-degree increments. As such, making targeted slits in rock, concrete, or asphalt no longer presents any challenge. Users can even execute a continuous 360-degree turn via an additional hydraulically operated rotation module (ERU). This Erkat rotator is designed for particularly tough cutting conditions.
