The invention relates to a device for clearing a helix gap of an auger, comprising a retainer for holding the device on a mast of a drill, a guide tube which surrounds the auger in portions and is mounted on the retainer, and a clearing element which engages in the helix gap and is mounted on the retainer so as to be freely rotatable about the drilling axis. According to the invention it is provided for the guide tube to be mounted on the retainer so as to be freely rotatable about the drilling axis, for the clearing element to be firmly attached to the rotatably mounted guide tube, for the guide tube to be axially fixed in the direction of the drilling axis, for the purpose of clearing, and for the clearing element, together with the guide tube, to be able to be caused to rotate about the drilling axis by means of a pulling procedure of the auger for the purpose of clearing the auger. The invention further relates to a method for making a drilled hole in the ground using a drill, wherein the device according to the invention is used.

The invention relates to a drilling unit with a carrier vehicle with a hydraulic supply, a mast, a carriage which can be moved along the mast and a hydraulic cylinder for moving the carriage which comprises a cylinder housing, in which a piston with a piston rod is mounted so that it can be displaced. The piston rod is fixed to the mast and the cylinder housing to the carriage. The carriage is connected to the hydraulic supply and comprises at least one hydraulic connection. The hydraulic cylinder is connected via the hydraulic connection on the carriage to the hydraulic supply.

Drilling unit

A construction machine comprising an undercarriage designed as a running gear and an upper carriage with a housing having side walls, wherein for access to the housing at least one housing opening with an access wall is provided, which is adjustable into an open position, and in an area in front of the housing opening a horizontal gangway is formed. At least one pull-out element is provided which can be pulled out horizontally between a retracted position and a pulled out position, in which the pull-out element projects horizontally from the housing, and in order to form the gangway a base plate is provided on the pull-out element.

Construction machine

A drilling unit, with a carrier vehicle, a mast rotatably mounted on the carrier vehicle about a pivot axis, which mast can be pivoted between an erect operating position and an inclined transport position, and at least one erection cylinder for pivoting the mast between the operating position and the transport position. For pivoting the mast in addition to the at least one erection cylinder an erection cable is provided which is guided via a cable deflection pulley arranged on the mast, on the carrier vehicle or on a carriage which can be moved along the mast, and in that in order to apply a pulling force to the erection cable via the cable deflection pulley an erection force can be transferred to the mast in the direction of its operating position. The invention further relates to a method for erecting a mast of a construction work unit.

The invention relates to a safety means for a construction machine having a carrier unit and an actuation unit, which is adjustable with respect to the carrier unit, comprising at least one detecting means for detecting the current position of the actuation unit relative to the carrier unit, an indication means with which the current position of the actuation unit relative to the carrier unit can be indicated, and an evaluation unit, by means of which, depending on at least one input value, at least one adjustment range of the actuation unit can be determined, in which the actuation unit is adjustable at a given safety against tilting of the construction machine, whereby the adjustment range can be indicated together with the current position of the actuation unit by means of the indication means.

Safety means for a construction machine

The invention relates to a construction machine having a carrier unit, an actuation unit, which is adjustable with respect to the carrier unit, at least one detecting means for detecting status data of the construction machine, and a computer unit, by means of which, based on the detected status data, at least one adjustment range of the actuation unit can be determined, in which the actuation unit is adjustable at a given safety against tilting of the construction machine. The invention also relates to a method for operating a construction machine of such type.

Construction machine having a computer unit for determining an adjustment range

A construction apparatus for foundation construction includes a chassis, a mast for guidance of at least one ground working apparatus and a support mechanism for the mast, wherein the mast is arranged in an adjustable manner on the chassis. The support mechanism has at least one support arm, which is pivotably hinged about a pivot axis on the chassis. A rotary encoder is provided for detecting the pivot angle of the support arm relative to the chassis as a degree of an adjustment position of the mast.
