KTR Chain Trenchers
The Kemroc KTR range of chain saw trenchers is a game changer for excavators, providing a versatile attachment that can trench not only in soils but also in rock with 90 MMPa compressive strength. With a range of cutting chain widths available, each fitted with wear-resistant picks, the KTR trencher can produce trenches with perfect profiles in widths ranging from 20 to 60 centimeters and to a maximum depth of 2 meters. When starting the trench, the KTR is supported while sumping down to the desired cutting depth. After reaching the required depth, the excavator can be driven backwards, or the trencher can be pulled forward with the excavator arm. The housing also features a spoil discharger to deposit spoil to the side of the trench, making the KTR range an efficient and effective tool for trenching projects.
