Abstract

A cutting frame for a trench cutter with oil-lubricated bearing seals for the cutter wheels and with a controlled hydraulic pressure-compensation device for the bearing seals is described. There is a pressure-resistant oil reservoir connected to the bearing seals via lines and there is an air-filled buffer space open at the bottom, exposed to the outside pressure and arranged vertically below the oil reservoir. The oil reservoir and the buffer space are connected to one another via a longitudinally displaceable piston, and the piston is preloaded by a compression spring in the direction of the oil reservoir. <IMAGE>
