Cutter and grab
Bauer trench cutters and Bauer hydraulic grabs are equipment for the panel excavation for the execution of cut-off walls. The centerpiece of the Bauer trench cutter system consists of a steel frame with two gearboxes attached at its base, which rotate in opposite direction around their horizontal axis. Cutter wheels suitable for the prevailing ground conditions are mounted on the gearboxes. Selecting the most suitable type of cutter wheels (equipped with ﬂat teeth, round shank chisels or roller bits) is essential for cutter progress which mainly depends on the geological conditions (particle size, density, abrasiveness, compressive strength, etc.). The accurate determination on the trench cutter for your project depends on the project ground conditions, the required trench width and wall depth. The ideal base carriers for Bauer trench cutter and mechanical or hydraulic grab equipment are BAUER MC 76, MC 86, MC 96 and MC 128 duty-cycle cranes. The entire hydraulic power supply of the attached cutter/hydraulic grab is provided by the hydraulic systems of the MC duty-cycle cranes which have been specially designed for those applications. Cutter and grab are available for a nominal width of 640 mm, 800 mm, 1.000 mm, 1.200 mm, 1.800 mm and 2.200 mm, and panel length of 2800 mm and 3.200 mm, however also special measures for width can be manufactured, if required.
