Abstract (en)
[origin: EP2275604A1] The apparatus has a mast (4) guiding a ground working apparatus (9) during foundation construction. An adjustable support mechanism (6) supports the mast such that the mast is arranged in an adjustable manner on a chassis (2). The support mechanism comprises two parallel support arms (61) pivotably hinged about horizontal and horizontally running pivot axes (71, 72) on the chassis. A rotary encoder (1) i.e. absolute encoder, detects a pivot angle of the support arms relative to the chassis as a degree of an adjustment position of the mast. An independent claim is also included for a method for operating a construction apparatus.
