A guide frame ( 1 ) for an earth drilling apparatus includes a support plate ( 6 ) for holding the drive unit ( 7 ) and a handle frame ( 2 ) having handle sections ( 17, 18 ) for holding and guiding the earth drilling apparatus. Operator-controlled elements ( 19 a , 19 b , 19 c) for controlling the drive unit ( 7 ) are arranged in the region of the handle section ( 18 ). The handle sections ( 17, 18 ) of the handle frame ( 2 ) lie in a plane ( 5 ) above the support plate ( 6 ). The handle frame ( 2 ) encloses the drive unit ( 7 ) as a closed frame and is connected via a carrier frame ( 8 ) to the support plate ( 6 ). The carrier plate ( 8 ) is fixed to the handle frame ( 2 ) via several coupling elements ( 20 ). Each coupling element ( 20 ) includes a vibration damper ( 24 ) which is arranged between the carrier frame ( 8 ) and the handle frame ( 2 ). In this way, the handle frame is decoupled by the carrier frame from the drive unit with respect to vibration without affecting the bracing of reaction forces via the handle frame.
