The invention relates to a control for at least one retainer of a transfer device for a rod section of a ground drilling device, wherein the ground drilling device is configured for moving a drill string, and the transfer device is configured for transferring the received rod section from a position in a rod magazine to a position on the drill string or vice versa, and the control is configured to move the retainer between a position above the rod magazine and the position on the drill string while the drill string is still moving.

Control for a retainer of a transfer device for a rod section of a ground drilling device

A device for inserting a pipe into an elongated cavity, comprising at least two pipe grippers which can be moved along a curved path and which are arranged and designed in such a way that they grip around the pipe at least in sections and, in the gripped state, they move curved at least for a portion.

Device for inserting a pipe into an elongated cavity

A ground drilling device with a drivetrain for rotating a drill string, wherein at least one section of the drivetrain is configured to form a channel between a force transmission element of the drivetrain and the drill string, wherein the channel projects through the force transmission element and the force transmission element may be driven radially in the drivetrain.

Ground drilling device, system comprising the ground drilling device, method for producing a ground drilling device, and use of a ground drilling device

A ground drilling device has a drilling carriage which defines a drill string axis, a drill rod magazine for a plurality of rod sections, and a transfer device for the transfer of a rod section between the drill rod magazine and a position of the rod section in the direction of the drill string axis. The ground drilling device also has a guide on a top of the drill rod magazine that is configured to guide movement of the transfer device.

Ground drilling device and use of a ground drilling device

A Ground drilling device having a drilling carriage and a sled movable back and forth on the drilling carriage, wherein at least one gear is present for the drive of the sled, whose rotary movement is transformed into a linear movement by means of a rack, wherein a force relieving pathway is provided to relieve the gear of a radially introduced force.

A ground drilling device having a drilling carriage, which defines a drill string axis, a first drill rod magazine for a plurality of rod sections and a transfer device for the transfer of a rod section between the first drill rod magazine and a position of the rod section along the drill string axis, wherein at least a first connection element is arranged at the first rod magazine and/or at the drilling carriage for the connecting of the first rod magazine to a second rod magazine such that the second rod magazine is arranged next to the first rod magazine.
