A cutting device for producing vertically running trenches in the ground includes a trench wall cutter which has a cutting frame, a first cutting wheel arrangement and a second cutting wheel arrangement. The cutting wheel arrangements are arranged adjacent to each other on the underside of the cutting frame in order to remove ground material underneath the cutting frame. The trench wall cutter has an adjusting mechanism, with which the first cutting wheel arrangement is adjustable in a direction lying obliquely underneath the second cutting wheel arrangement.

Cutting device for producing vertically running trenches in the ground

The invention relates to a foundation construction device for producing trenches in the soil comprising a frame, at least one soil-removing device arranged on the frame and a control device for controlling the foundation construction device in the trench, wherein the control device has at least one control body which can be adjusted between an inoperative position and a projecting control position in order to rest on a wall of the trench. Provision is made for the control body to be adjusted into a first projecting control position on a first side of the frame or into a second projecting control position on a second side of the frame that lies opposite the first side of the frame.

Foundation construction device for producing trenches in the soil

The invention relates to a foundation construction device for making trenches in the soil comprising a frame, on which a soil-removing tool is arranged, and a control device for aligning the foundation construction device in the trench having two control flaps, which are supported pairwise opposite each other on the frame, and having at least one extendable and retractable guide wheel arranged on the frame.

Foundation construction device for making trenches in soil

The invention relates to a winch device with a first winch having a first winch drum and a second winch having a second winch drum. There is also a synchronizing device through which a rotation of the first winch drum can be synchronized with the rotation of the second winch drum. Further, a differential shaft with a first synchronous wheel and a second synchronous wheel is provided, said first synchronous wheel being connected via a first rotary connection device to a first drive and the second synchronous wheel is connected via a second rotary connection device to the second drive.

Winch device

The invention relates to a method for making a trench wall in the soil, in which a trench wall cutter having at least one rotatably driven cutting wheel is lowered into the soil, whereby soil material located below the cutting wheel is stripped and a cut trench is made and a settable liquid is supplied into the cut trench. For this purpose it is intended that a gas is supplied into the cut trench. The invention further relates to a trench wall cutting device for making a trench wall.

Method and trench wall cutting device for making a trench wall in the soil

The invention relates to a trench wall cutter comprising a bearing shield, on which at least one cutting wheel is supported in a rotatable manner. Between the cutting wheel and the bearing shield at least one sealing member is provided. For the lubrication of the sealing member a lubricating device is provided, which has a lubricant inlet port arranged above the cutting wheel.

The invention relates to a cutting wheel for trench wall cutter, having a cutting wheel hub and at least one cutting tooth holder, which is located in substantially radially projecting manner on the cutting wheel hub. The cutting wheel according to the invention is characterized in that there is at least one mixing blade on the outside of the cutting wheel hub.

Cutting wheel for a trench wall cutter

The invention relates to a hinged tooth for a cutting wheel comprising a pivot bearing for pivotally supporting on a pivot pin located on a cutting wheel hub, a cutting tooth support extending from the pivot bearing and a steering arm extending from the pivot bearing substantially in a direction opposite to that of the cutting tooth support. A simple and at the same time stable arrangement is achieved in that the pivot bearing, the cutting tooth support and the steering arm are designed as a one-piece support.

Hinged tooth

A cutting tooth is fitted in a cutting-tooth holder of an earthworking appliance which has at least one cutter. The cutter is mounted ahead of a cutter-support region, as seen in the cutting direction, and has at least one cutting edge. The size of the cross-sectional areas of the cutter-support region which lie perpendicular to the cutting advance direction and intersect the cutting edge remains approximately constant in the area which is delimited by in each case two such cross-sectional areas.

Cutting tooth for earthworking

On a slurry wall device having a cable mounting, on which is attached a supporting cable for guiding the slurry wall device, is provided an adjusting device, with which a supporting cable contact point can be laterally displaced, so that the slurry wall device can be controlled with respect to its deflection in the trench. This permits the orientation of the slurry wall device and consequently its contact angle ofthe bore hole bottom to be controlled by a particularly simple device. It is also easily possible to retrofit a slurry wall device with such an adjusting device.

Direction control system for a slurry wall device

A trench wall cutter with a drive mechanism which is attached to the cutting frame in a position which is spaced away from the bearing shield with a gear for driving at least one cutting wheel is provided. Between the drive mechanism and the drive pinion of the gear in the bearing shield there is a drive shaft. To reduce wear on the drive shaft bearing and gear wheel in the gear an external spiral tooth system is formed on one end of the drive shaft which fits into a connecting sleeve with an internal tooth system. In the internal tooth system the drive shaft with its external spiral tooth system is held rotationally fixed with the capacity to be deflected around the axis of the drive shaft. The connecting sleeve is also joined to the drive mechanism or drive pinion of the gear.
